Subject: [Elecraft] Wanted P3

Dear Elecrafters,

After a long period of inactivity, I have been back on the air regularly with 
my K3 (serial 7***). I operate CW and some FT8/FT4. It's a QRP one and has some 
addons. When I bought the original kit, I had the idea of getting a P3, which 
never happened at the time. Now they are discontinued, so I wonder if anyone 
has a P3 they would be interested in selling to me? Since I'm in Ireland it 
would be best if it were somewhere in Europe as freight charges from the US 
have become pretty huge.

73,

Paul EI5KI

Re: [Elecraft] K4 Rx is awesome...

[George Thornton]

That was not my experience.  

Right out the bat we were occupying a frequency and calling.  We were heard so 
well we found ourselves at the bottom of a pileup for the next two or more 
hours.

You might want to take a closer look at your various mic and transmitter 
settings.  These have to be adjusted correctly for maximum effect.

I’ve been using my K4 at 100W (per the FD rules) this afternoon on several 
bands.
I am 1D OR.
I can hear many many stations but hardly any of them can hear me.
To me, this means that the K4 Rx is bomb-proof, sensitive, selective, and just, 
well, awesome.
If the other stations had better receivers, they might be able to hear me 
calling them. 
They are obviously bogged down with on-site overload/spurii/phase noise etc. 
What a pity. 
I gave up replying hopelessly to CQFD’s from other 100W stations and went and 
did some woodworking instead.
Much more satisfying. Oh well….

I was wondering too about the huge signal in the center of the waterfall…. 
Hopefully, the ARRL “Clean Signal Initiative” will help encourage manufacturers 
to clean up these messy transceivers!

I recently discovered several presentations by Rob Sherwood - famous for his 
receiver testing.  I was fortunate to get to meet him at Hamvention this year 
and thanked him for his work.  His new(?) message:  CLEAN UP THE DIRTY 
TRANSMITTERS.  And he calls out specific models!  BTW, Elecraft was NOT on the 
lists, but it is surprising which ‘high end’ transceivers were.  It’s worth 
reviewing his presentations on the subject - and it kept me from a bad upgrade!

Re: [Elecraft] Field Day Operation

[George Thornton]

Our group was a 6A.  The signal was from the 20 meter voice station in our 
group.  This station in the picture was GOTA operating under a separate call 
sign.

The 20 meter voice station showed up large on our waterfall, but we kept 
elsewhere on the band and no problems.  

There was another station of ours operating CW on 20 meters, separated by about 
400 ft. in elevation.  We had no problems with them.

Interestingly, at one point the 20 meter station chair contacted me and said he 
was being desensed by us and the 20 meter CW station.  I think they were using 
an Icom rig.

The conclusion, the K4 is just as well protected from adjacent station 
interference as the K3. Elecraft is the rig of choice in a multi-station 
operation.

This was my station.  

I appreciate the suggestion and will see what we can do next year to increase

Thanks for producing such a quality rig.  It was a joy to use and was very

Re: [Elecraft] Elecraft 80M SSB Net Report

[George Thornton]

I have a similar sized lot and am located in a city.

Antennas are everything on HF and the bigger the better.

I tried just about everything but eventually sprung for a rooftop tower and a 
SteppIr 3 element.  Huge improvement.   Much better than a dipole.

I hear the hex beam antennas work pretty well, are less intrusive and don't 
require as much in the way of a tower or rotor.

Re: [Elecraft] COM port problems

[George Thornton]

It is possible the parameters set in the computer after reboot don't match 
those set in the program.  Check the port and baud settings.

Generally xom port settings need to match for communication to occur.

Subject: [Elecraft] COM port problems

OK, got a massive problem that just cropped up this evening that is far
beyond my understanding that has completely killed my ability to use my K3
with my computer.



After restarting the PC, suddenly I cannot communicate with the radio using
DX Lab Suite or N1MM+ on the assigned COM port. I have downloaded the K3
Utility software and it is able to connect to the radio on COM5, its usual
port, and invoke macros via the Utility. So I know there's proper
communication between the radio and the PC. But once I close down the K3
Utility program I get the first major problem. The radio goes into transmit
for 10 seconds, releases for about 4 or 5 second, and goes back in to
transmit. Only powering the radio off and back on again stops this behavior.

The main issue is that no CAT control software seems to be able to connect
to the radio at all. The radio is on COM5, and has been for at least the
last 4 or 5 years, and until today it has just worked, even after building a
new computer last November. I just rebooted today and everything went to
heck.

The kicker is that's it's not a K3 hardware problem, and since it works with
neither N1MM nor DX Lab software any more it's apparently not those programs
either, and quite frankly I just don't know where to look next. Compounding
the issue, and likely related to it, the N1MM Rotor control cannot find
either COM port assigned to the rotors (COM1 and COM3). I have tried
removing the ports and re-adding them in Device Manager but the problem
still persists. I am absolutely prepared to pay a certified systems
professional to diagnose and fix this, but with ultra-specialized radio gear
I doubt they'd be able to figure it out either. Any suggestions? I'm
basically QRT until I can fix this.

official company in design and appeared to be an outlet for the company.

I placed a small order as a test but then changed my mind within an hour after 
reading up on problems.  I tried to cancel the order with the company but of 
course they did not respond and claimed to have shipped.  I of course never got 
anything.

I went to Paypal who of course paid the company.  I kept crying fraud and after 
a couple months of back and forth nonsense and my persistence they finally 
refunded.

I agree Paypal offers no protection for the most blatantly fraudulent 
transactions.  They are almost complicit in the fraud from their side because 
they could easily see a pattern of activity

Their own inaction under these circumstances almost makes them complicit in the 
fraud itself.

Re: [Elecraft] Unassembled K2 Vs Assembled Marketability

[George Thornton]

As a former K2 owner I can say at least half the fun of one of these was to 
build it myself.

This is one of the last kinds of major kits that involve assembling all the 
components onto a circuit board.  Today with all the surface mount devices the 
technical challenge is too much for most of us and kits largely become a 
mechanical assembly of already completed circuit boards.

I don't know the answer to the question though I agree with someone else who 
said they are different commodities.  However, in the long run an unopened kit 
may be worth a small fortune, like some unopened games and Barbie dolls are.  
The K2 deliveries are presently TBD . . . I have one (my fifth) on order and no 
ESD is posted.  I assume it's a parts problem.  The K2 has already had a number 
of small component modifications made as the traditional parts have become 
unobtainable or uneconomic.  If it were possible to place an order for the 
final five S/Ns, whenever that happens, I'd pay for them today.  What say, 
Wayne -- will you make me that deal?

Re: [Elecraft] KX3 in multi radio environment

I normally use a K3s in a highly competitive 6A field day environment.  One

I don't have a KX3, but a friend does and he has a question regarding the KX3 
receiver in a multi transmitter environment like Field Day.  I would not expect 
it to be as good as a K3, but is it usable?  Anything special you have to do to 
it?  I'm thinking at a minimum a set of band filters, which would be easy even 
with the 100 watt amp.

Re: [Elecraft] OT: Nano VNA

[George Thornton]

Roughly in the same price range is the Array Solutions AIM UHF.

In the course of my HAM career I have used a variety of analyzers.

I have a NanoVNA and it does work, but its menu system is horrible and counter 
intuitive.  In addition the use of tiny connectors is not ideal for our common 
N and PL 259 equipment.   It also has to be recalibrated a lot more than other 
units and that can be a hassle.  I don't completely trust it because I am not 
always sure I am using it correctly.

My favorite analyzers were the AA series and the AIM UHF.  The AA 600 I owned 
was a stand alone unit and it was pretty trustworthy.  

The AIM UHF seems to be very similar to the VNWA referenced below and was in 
approximately the same price range.   It also worked through a computer.

In the end I much prefer the AIM UHF.  Although it was a bit inconvenient to 
have to bring along a computer, I found that in nearly every situation it was 
worth the inconvenience. For instance, graphing a full SWR curve along a 
frequency range was very helpful to analyze antenna tune.  You can see exactly 
how the curve goes including the lowest point and you could make gradual 
antenna modifications to get perfect tune.

Re: [Elecraft] using the sub receiver in a K3S with a 2nd P3?

[George Thornton]

The P3 is designed to work with both the main and sub receiver using the IF 
output.

I don't think you can separately hook up a P3 just for the sub receiver.  I 
think the radio puts out a signal to the IF output for whatever receiver is 
active at the time.

Re: [Elecraft] Giving Up

[George Thornton]

I am not active in CW, most of my HF work is voice.  I do some contesting but I 
have conflicting time demands that make it difficult  to spend a lot of time in 
the operating chair.  

The K3 has been my rig of choice and I am very comfortable with the rig.I 
am of course intrigued by the K4.

Improved audio alone would be a reason to upgrade.  My biggest concern with the 
K3 is the quality of the audio.  It has a tinny, harsh sound that can wear on 
you if you are in the contesting chair for long hours.  I have moderated the 
sound by use of a pair of Sounds Sweet speakers and I bring those bulky beasts 
with me when I go into the field.   

I am looking for an opportunity to compare the K3 and K4 side by side. I also 
want to see how the K4HD shakes out.

Doug,

You didn't mention what rig you are going to buy instead.  Be sure to be aware 
of its limitations before you buy it.

For example, the FTdx101MP has three show-stoppers (for a CW op like me), 
despite it's impressive numbers in the Sherwood table:

   - Poor QSK performance (the clicking keying relay cannot be disabled,
   same problem as the IC-7300)
   - No CW sidetone output on USB Audio CODEC-- cannot record both ends of
   your QSOs (a contest requirement in some contests)
   - Mouse wheel is not supported for fine tuning or RIT (I think).  K4
   supports this very well

As for comparing the K4 to the K3, despite the K3's "superior" numbers in the 
Sherwood table, the K4 SOUNDS so much better than any K3.  The K4 audio is just 
SO CLEAN compared to the K3, which makes a big difference when a pileup calls.  
That quality is not captured by any subjective measurement.
The narrow DSP filters (down to 50 Hz) also seem to work so much better in the 
K4 than the narrow 250 or 200 Hz crystal filters in the K3 -- no ringing.

Bob, N6TV

Re: [Elecraft] Giving Up

[George Thornton]

I think it is correct to say the basic k4 does not exceed the K3 raw 
performance (based on the Sherwood engineering standard) but I think the 
results are pretty close for practical purposes.  I would not say the K4 is 
materially worse.   I think it would be up to individual K3 owners to decide 
whether to sell and pay the difference for an upgrade.  

I looked at pricing for the Yaesu stuff and the comparable dual receiver model 
comes out at $4700.  Their 200 watt version is advertised at $5200.  

We don't really know how much the superhet option will cost but what if it was 
a grand more, that would put the top of the line K4HD at $5000.   At that level 
I would look more at a full feature comparison before I reached a conclusion 
about which is a better deal.

I don't have full information on pricing and options so I don't know if my 
numbers are off.

We are dealing with a US company versus foreign made and that may also be a 
factor.

I also suspect Elecraft could in the future come out with a scaled down model 
that has only one receiver and that could become a lower cost option.

Except that the K4 (not K4HD) does not equal the K3 for raw performance.  The 
K4HD with equivalent performance and accessories is going to cost a fortune, 
with the extra cost going mostly into creature features.

And you're forgetting comparison to rigs from other manufacturers. If you 
create a sliding scale of cost versus performance for various rigs, Elecraft 
doesn't come out on top on any rig anymore.

Re: [Elecraft] Giving Up

[George Thornton]

I don't know the FTDX10 but it looks like it has a single receiver and can't be 
updated.

I note these Yaesu rigs seem to have crystal filters and use a combination of 
superhet and direct sampling architecture whereas the K4D is direct sampling.   
I would hold off on reaching conclusions on relative performance until the K4HD 
comes out and is tested.  Only then would you get comparable radios.

Except that Yaesu radios have a long history of generating nasty clicks, and

Re: [Elecraft] Giving Up

[George Thornton]

I agree that the price for the K4 has to be compared with the fully loaded K3 
plus P3.   In that respect it is not overpriced.

I don't think we should make too much of the Sherwood Engineering test data at 
this point.I would suspect it would be hard for the human ear to tell the 
difference among the top eight or ten models on the list.  I also think that 
when the K4 HD unit is out you might see higher results.  I suspect direct 
sampling technology is not as capable as superhet when it comes to separating 
out closely spaced signals which is what Sherwood Engineering uses to rank 
radios.

GM Doug,    A fully loaded K3 P3 was always dear.   It rivalled the 7850 price 
but did not reach the cost while arguably being the better radio.   The fully 
loaded K4 is less expensive to my reckoning in todays money than the loaded K3 
with P3 and physically smaller.    I suspect it may not be so much superior to 
the K3 in RF terms except that it is in the important area of ergonomics.   The 
wait has been excessive for sure.Your reasonng is understandable.   Hope the 
next radio is great.   Meanwhile keep enjoying ham radio.I will keep waiting.73

Giving Up Sadly, I've decided to give up waiting for the K4. I'm probably far 
down the list anyway. Their are numerous reason for this decision. First, there 
is the cost. With a tuner the price is $4600 making it one of the most 
expensive transceivers on the market. I fully realize that the K4 is feature 
rich and extremely well designed. I would never take anything away from 
Elecraft's engineering ability. The K3 set a new standard of performance that 
made the other manufacturers substantially up their game - which they did. But 
is the K4 going to do the same thing the K3 did? To me, it doesn't look like 
it. Innovative in some, perhaps many ways - yes. A new trend setter? I'm not so 
sure. When the K3 came out it was very competitively priced. I'm not sure I 
would describe the K4 with the same words. It is unquestionably an expensive 
radio. At this point the price/performance just isn't there for me. I sold my 
very complete K3 station several years ago in anticipation of the K4. But now 
the waiting has left me thinking about how much I'm willing to invest and 
whether or not another brand whose transceivers are as much as $1500 less and 
whose performance seems quite impressive will meet my needs. After literally 
several years of contemplation I conclude that, for me, the K4 is not worth the 
price. $3600 (with the tuner since every other significant radio includes one) 
would seem competitive and I would jump on it at this price. But as it is? 
Can't see doing it. I apologize if feelings are hurt or I've made anyone angry. 
I'm leaving the list since I'm no longer waiting patiently for what we once 
called Vaporware.Good luck to everyone on their current and future K4s.Doug --

Re: [Elecraft] P3 freezes

[George Thornton]

I have a more or less fully loaded K3 with the synthesizer upgrades.  The K3 
was gone through at the factory and appears to be running well.

I have a P3 that also has the SVGA card and the transmit monitor add on.

On a number of occasions my P3 seems to freeze and fails to move with tuning as 
I turn the tuning knob.

Before I call Elecraft for guidance I wonder if anyone has any suggestions.  

THANKS.

Re: [Elecraft] Speaker upgrade

[George Thornton]

Which radio?

With respect to the K3 I would recommend use of external speakers.   They can 
improve comfort for longer listening periods.

I am a personal fan of the Sounds Sweet communications speakers.  Unfortunately 
although the web page remains open they have not been selling them for years..  
If you can find them used I would grab a pair.

I don't know that replacing the internal speaker would be worth the trouble.

Re: [Elecraft] Can I rent a K4?

[George Thornton]

I think Elecraft has enough on its hands with COVID 19 just getting these rigs 
designed, updated, built and shipped.  

I am not aware that any major manufacturer of HF amateur radio transceivers 
maintains an equipment rental program.

A rental program would be complex to administer.  You would have to deal with 
insurance, shipping concerns and complaints that inevitably are part of such a 
program.  Plus a legal team on hand to deal with problems that result from a 
rental experience gone bad.  The program would have significant staffing 
requirements.   I would think even if they were interested in offering this 
service, they have many more pressing concerns giving COVID 19.

Re: [Elecraft] Shack Equipment Storage

[George Thornton]

Wet is much more of a problem with electronic equipment than 100 plus degree 
heat.

I live in Western Washington, my locality has about the same total rainfall as 
the middle east coast states but we rarely have downpours.  It just drizzles 
and mists all the time.  

I have owned boats in this climate and I know proximity to water greatly 
magnifies the problem.   Electrical connections corrode quickly in a damp 
marine environment.  I used to have to go through my boat wiring system and 
clean contacts annually to keep the lights functioning.

A small heat source does wonders to lower humidity.   Even an incandescent 
lightbulb can help in small spaces.  Just running your radio generates heat 
that dissipates humidity within the radio..

I have a wood shop in an unheated garage. I have to keep a heat source in there 
in the winter to keep the tools dry, otherwise my tools will rust away.

I would worry about condensation. I live in New England. New England is the 
only part of the country except for the coastline in WA, where there is a 
positive water budget typically. In other words, more rain falls than is 
evaporated or used up.  My ham shack is 1/2 mile from my house and was 
unheated. It was hard on the equipment.  Very hot wx was not a problem but cold 
temps and then the arrival of warmer and moist air would produce water droplets 
all over the gear.  Transformers would stay very cold and the water would drip 
off of them when the temps warmed a little bit.  Anything that used high 
voltage was subject to explosions if you were foolhardy to turn them on. It was 
all due to the water.

What I did was install a propane heater with a special thermostat that allowed 
operation down to 32 degrees. I set the temp to around 40 F. That keeps most of 
the condensation at bay. I also put in a solar heater on a south facing outside 
wall, and it pumps warmer air inside if the Sun is out. On a sunny winter day 
in January it will be 50 degrees in the room during the day. I have had no 
trouble with this setup. I am just about through with my 1st 100 lb propane 
tank and January is just about finished, so the cost is not too bad. You must 
use a vented propane heater. The unvented ones, or portable K1 space heaters 
like Kerosuns etc all produce water vapor and are no good for what we want. 
Maybe in a desert climate things will be different, but that is what works for 
me.

I have an unheated room as well, but only keep rugged stuff there in winter. 
Homebrew KW amps etc seem to do OK. I would never leave a KX anything there 
however. Been there. Done that!

Re: [Elecraft] K4 Receive Filter question

[George Thornton]

I have followed the Sherwood Receiver test data over the years and I know 
Elecraft has always been in or near the top spot.

I also would be reluctant to upgrade to a K4 if my K3 is the same or pretty 
close to the same in the key performance characteristics.

I wonder whether we are nearing the theoretical limit of what can be gained in 
receiver performance.

The difference among the top eight to ten on the Sherwood list is not likely to 
be practically significant.

I work in the 2 to 3 db above the noise floor CW, and 6 to 10 db above the 
noise floor on SSB now, (that is why I presently own a K3s and a P3VGA)  so I 
guess I will have to wait for the real answer. I really cannot believe that 
Elecraft did not run their own test. If and when I spend my cash I am not 
looking for the pretty blinkie colored lights and a fancy screen, I want 
performance.  My really big issue is: receiver noise floor, sensitivity and DSP 
that does not distort or degrade the incoming signal.
 But thank all of you for your input  and I truly appreciate all the comments.

Re: [Elecraft] Sherwood Receiver report K4 ?

[George Thornton]

It is my understanding Sherwood Engineering obtains a K4 and tests it.  Until 
they have done that it will not show up on the list.  Since Elecraft is a major 
player they will test it when they can.

Re: [Elecraft] Buying a Used K3(S) - any things to consider?

[George Thornton]

I don't know the answer to all your questions but I will note the following:

The KIOb3 board is not essential.  You just need to have a serial port or a USB 
adapter for connecting with a computer.  I never bothered to upgrade mine when 
I upgraded the synthesizers on my K3.

Many of us have found the panadapter to be very helpful.   The P3 panadapter is 
a pretty sophisticated device and many of us have found it really helpful 
particularly in contest situations.  It is kind of like moving around the band 
with your eyes open instead of operating blind.

Subject: [Elecraft] Buying a Used K3(S) - any things to consider?

Sorry but I just need a little help with this - I'm in the K4 Group 3 list and 
know it will be a while before I get the call, so considering buying a used 
K3(S) in the mean time. This would be my first Elecraft and I am hesitant to 
jump in knowing the support has ended. Are there any guidelines to consider if 
I do purchase one?

Things like:
    1) Find the KIOB3 card that has ACC/RJ45/USB or doesn't that matter?

    2) What's the deal with the SPEAKER jack always looking like a horseshoe 
with the chrome ring missing? Is that an easy part replacement or does it mean 
something else? I tend to see this a lot in listings and that concerns me.

    3) Why on some radios the ANT jacks are different colors? I'd like to have 
both teflon white but also see the old brown bakelite color in pictures.

    3) Any serial number above range to pick from? I know these are all
5-15 years old but I'm still running a 33-year old Icom Superhet with a 250hz 
xtal filter; not a real fan of visual eye-candy waterfalls or the Pan adapters 
- call me crazy but it seems distracting. Maybe the K3 with a regular screen 
would be better for me long term than the fancier K4 (although it's beautiful).

    4) Does the CW decoder display work when you have the second RX 
installed/enabled?

The going used rate for a K3 is around $1500-$2500 and $3000-$4000 for a K3S 
(which is the K4's starting price but less than 5 years old). I don't want to 
have to beg for boards if something goes wrong after an unseen online purchase. 
I've ruled out the other SDR alternatives from Icom, Kenwood and Flex as I know 
I want an Elecraft due to their heritage. Being an SDR noobie I'd love to try 
one first but that's not going to happen.

Appreciate any pointers...

Thanks,

Tony - KX3H

Re: [Elecraft] Tuning Random-Length Wire Antenna with K3 Internal Tuner??

[George Thornton]

You might take a look at the SGC company website.  They make excellent 
autotuners designed to be mounted outdoors at the antenna.  The site includes a 
number of guide articles and manuals with a wealth of information.

These tuners are fully automatic in that when you first transmit on a frequency 
the tuner automatically tunes and puts the setting for that frequency in 
memory.  

When operating these with the K3 you use the tune button (long press on the 
xmit key) and watch the SWR go down as the unit tunes.

Re: [Elecraft] k3 no RF in transmit

[George Thornton]

I concur with this statement.  

For instance, SGC makes "smartuners" that can be remotely mounted from your 
transceiver.  These tuners work automatically to tune the antenna when a 
transmission occurs.  The long press on the XMIT button function transmits a 
low power continuous tune sufficient to activate the SGC tuner's tuning 
function.

The ATU tune works with the internal tuner.

You've made a mistake, a long XMIT (TUN) press is for applying a small amount 
of output, to match with the antenna (or check the SWR).

ATU TUN (ATU) applies power to the internal tuner, if any, if enabled. Two 
different functions.

Re: [Elecraft] K3S MIC Problem

[George Thornton]

The K3(s) as I understand it has protective circuitry that will reduce mic 
output if there are return power issues.  

I once had an experience during Field Day where my K3 was suddenly not 
transmitting or doing so at a very low level.  Mine was traced to a SO239 
connector that had worked loose and was not making good connection.  

You can also try recalibrating TX to see if that helps.

In my case the unit went back to the factory for  diagnosis, inspection and 
repair.  Elecraft's gentle ministrations restored it to full function and I 
have not had a problem since.

and this seemed to prevent the problem most (but not

Re: [Elecraft] K2 purchase considered

[George Thornton]

I have owned both a K2 and K3.  I have also worked but have not owned a KX3.

I am also not a CW operator.

The K2 was one of the more interesting kit projects, I had a lot of fun with it 
and learned a lot.  It is built "old school" with very little surface mount 
chips.  

It is however a 22 year old design.  The K3 and Kx3 are more recent design and 
have significantly improved receivers.

John,

The K2/10 does not have a KEYOUT signal, so you would have to add one to key 
the KXPA100 (it is not a kit available from Elecraft).  You can see what needs 
to be added at http://www.mmccs.com/mmarc/n0ss/index_k2.html
- scroll down to K2 (basic) External T-R Relay Driver.  Contrary to what is 
stated, no kits are available - N0SS is SK.

Other than that, the K2 is still a good transceiver even though it is a
22 year old design.

Re: [Elecraft] FS: Elecraft PR6 Preamp - SOLD

[George Thornton]

FYI they still sell the PR6-10 preamps new from Elecraft.  I just bought one a 
month ago.

I have the K3 and I have made some (but not all) of the conversions to K3s 
standards.   

My K3 is performing well.  I have my eye on the new K4 but want to see some 
comparative performance test results before I buy.

For those of you picking up legacy K3 rigs recently, you might want to consider 
this option.  The PR6 was designed to help boost 10M and 6M signals as an 
add-on unit which plugs into the RX IN/OUT connections on the back of the K3 
with supplied BNC connectors.  There is a power connection and a control so 
that you can turn on the PR6 by simply pressing the RX ANT button on the front 
of the K3.  Here is a link to the user's manual:

$60 or best offer, postpaid to lower 48.

Re: [Elecraft] K3 going expeditionary

[George Thornton]

Concur.  

The K3 can in my experience be vulnerable to voltage drop which can happen with 
a questionable power source.  

For a rig like the K3 you should draw straight from the battery.  You can add 
some additional protection in a mobile setup by incorporating a voltage 
regulator In the circuit just before the K3.

You could do that. I wouldn't advise it for other reasons. Why don't you 
measure the current at different power levels when on a power supply? There is 
a current display on the radio. The cigarette plug is not directly connected to 
the battery. There is likely to be poor connections resulting in IR losses and 
other problems.

Re: [Elecraft] Field Day and clean radios

[George Thornton]

Assuming this is not just keying you are also going to have to disinfect the 
microphone.  You also have issues with computer keyboards for logging.

For working with computers I would think the commercial equipment wipes would 
be OK.

I typically wet paper towels with alcohol so it is damp but not dripping.  I 
have used that method to clean screens and keyboards on laptops with no 
problems.

I do think the virus is pretty vulnerable outside the human body.   70 percent 
or higher concentration of alcohol wiped across a surface should kill any virus 
that got there.

Re: [Elecraft] K3 on SSB

[George Thornton]

I have owned a K3 forever.  I am not myself a contester except on Field Day.

Most performance measurements for the K3(s) show it still in the top group in 
terms of ability to hear weak signals adjacent to a stronger signal, an 
important measure for performance in a contest.  Until recently they were in 
the #1 position or near #1.  Now some newer rigs have barely exceeded the K3S 
performance by a very small amount, we will see how the K4 performs, I suspect 
Elecraft will be at the top of the heap again.I am not sure you can 
actually tell the difference in performance at this level.

The main criticism as I understand it with SSB is that the K3 produces a 
harsher sound on SSB than some other rigs.  While this will not interfere with 
your ability to operate, it can irritate the listener over time. 

You can moderate that somewhat through EQ settings, but I do think that some 
other rig manufacturers have been noted for more pleasant sounding audio. 

For me, long ago I found some really nice speakers (Sounds Sweet, no longer in 
business) that do an excellent job of making my K3 with updated synthesizers 
sound pleasant.   

I am looking forward to the K4 getting released and tested.

I will probably not be in the market to purchase anything major until this 
coronavirus situation stabilizes and the economy gets back to normal.

Previous posts suggest a consensus, or at least a widely-held opinion, that the

CW, and on SSB in only one contest and a few casual ragchews and nets.  In what 
ways is the K3 inferior to others on SSB?  Yes, this is a question, not an 
argument.  And is the K4 designed to correct whatever those flaws may be?  I 
have not yet ordered a K4.  Knowing this info would be helpful to that

Re: [Elecraft] Off-Topic: Your advice/suggestion about antenna

[George Thornton]

I would add the following comments.

You can easily reach the point of obsession with antennas, and some of the 
choices involve heavy expense, tons of room, tolerant neighbors and a lot of 
maintenance.

I think the Yagi antennas are among the best choices, by their nature they 
concentrate strength in one direction.  As a horizontal polarized antenna they 
are less affected by noise than vertically polarized antennas.  They also 
heavily concentrate power in one direction, and they naturally filter out 
interfering signals coming from the sides.  They are fun and work really well.

I am a SteppIr fan and their antennas are well built and reliable.  I have done 
wonders with a 3 element trombone version using just 100 watts in an urban 
location with the antenna mounted on a nine foot rooftop tower.

Yagis do involve heavy wind loading and they do require a sturdy tower type 
base of support and a substantial rotor.   

Size is always better but with size also comes expense, hard work and 
maintenance.   Looking at SteppIr, a three element Yagi is light enough to be 
raised by hand with a small crew of two or three people using a gin pole.  The 
larger SteppIrs weigh around 250 lbs and you will need a boom truck.  

There is a lot of wind loading with Yagis and wind storms can cause a lot of 
damage.   Your rotor needs to be pretty sturdy; even the three elements need a 
Tailtwister or better.  You have to go really heavy duty with the big boys and 
that costs a lot more money.

Our Mike and Key field day site sports a wide variety of Yagis.  I run the GOTA 
station with a small three element trapped Yagi that I can support on a 
temporary tripod mount made out of Army surplus aluminum tubes.  The 40 meter 
Yagi is made of wire, six elements with what looks like a 100 ft boom, erected 
on lines run between trees.

Subject: Re: [Elecraft] Off-Topic: Your advice/suggestion about antenna

Duane,

I agree on both points.  The antenna is THE most important element of any 
station (the accepted maxim is it's 90% of the budget but most hams are 
'cheap').  The radio is useless without a decent antenna.  An EDZ can work well 
but the peaks and nulls vary on every band and wind in the trees can be an 
issue.  Height matters, a LOT too.

I also hid (in plain sight) a similar 370' EDZ (at 35') antenna IN the HOA 
space (shot a wire over some oak trees) for years without it being seen and it 
worked well (other than the noise floor was obscenely high, all the time 
because it was urban).  It absolutely ROCKED on 40M (the noise precluded 
hearing much on 160M but I got 15-20 countries).

If budget is less of a concern, you might want to consider SteppIR, starting 
with the 2 element Urban beam (40-6M).  The only other comment along that line 
is leave a LOT of headroom capacity when selecting a rotator, they take a lot 
of wind abuse.  There are other beam antennas worth consideration, many are 
less expensive.

When I moved away from the HOA infestation area into rural with a 40 db
(average) lower noise floor, in time I went from all band (R7, dipole or
vertical) wires to a SteppIR DB36/80 (80-6M) which gave me an average of 
another 10 dB of GAIN in reception (plus directivity to null noise even further 
AND transmit gain too).

I bought the antenna, rotor and tower at an estate sale (SK sale), saving many 
thousands of dollars.  The son (a non-ham) just wanted it all gone, I assisted 
;-) so keep watch, ready to 'attack'.

The sole remaining wire is an Inverted L for 160M.  I greatly prefer this to 
any dipole because the one wire is not pulled/stretched between multiple trees 
when it's windy (and the trees NEVER sway in sync at the same moments).  It 
moves precisely WITH the tree motion, it isn't stretched or pulled.  However, 
it's moderately deaf on 160M, I'll have to add an RX array (RBOG or 8 square 
are the current considerations) yet I'm now at 131 countries worked on 160M.

The sole sticking point remaining is my requirement that NOTHING antenna can be 
seen from the house (I bought an amazing view, it came with a house), so even 
with the acres I have, I'm limited to a few acres total, further reduced by 
proximity to the power lines along the road. Fortunately my neighbor (700' 
away) is also an HF active ham with even more acres (same visual rule) so we're 
considering a shared RX array (SDR and wifi based, which removes much of the 
desense issue too).

So my suggestion is that you look at the larger picture and perhaps even start 
fresh, not re-modify the original plans (make it a Revolution, not just an 
evolution).  Part of my move (escape to) here was just for that reason, to 
start with a fresh station based on simplicity of operation (which takes a LOT 
of planning and work to obtain; in a couple years, it'll be there, I hope.)

Re: [Elecraft] Found: P3

[George Thornton]

Concur that a standard computer VGA card will not work here.  On the other had 
if you are referring to a pre-owned Elecraft SVGA option card that you buy used 
on the market I don't think that will be a problem, I am not aware of later 
generation cards and most of the feature upgrades are in firmware anyway.  If 
that is what you are thinking you might want to make sure by calling Elecraft.

The SVGA option works with almost any monitor for sale today that has a 
standard VGA plug connection.

While you are at it I would speak positively about the tx monitor option.  I 
have found that really useful to quickly verify my transmitter is operating 
properly and the microphone settings are ideally configured.   

I use my K3/P3 combination a lot in Field Day.  Things can go wrong in this 
setting, including disrupted antenna feed lines and antenna malfunctions.  In 
addition with multiple operators using the equipment you don't' know if someone 
has altered settings in some manner.  With the TX  monitor equipment you 
visually see what you are doing with every transmission.  You catch something 
going wrong immediately and can move to correct it.You also know if no one 
is responding to you it is more likely due to band conditions or who is out 
there rather than your equipment.

Re: [Elecraft] When might there be a P3 sale or drop in price

[George Thornton]

That was my experience as well.  I initially had the LP Pan but later switched 
to the P3 panadapter.

The P3 in my experience is far easier to use under practical operating 
conditions.  You can widen or shorten the span to zoom in on a narrow part of 
the band, or zoom out to see across the band.  You can easily adjust to put the 
noise floor at the bottom of the screen and adjust the height of signals so it 
all becomes more easy to follow.All of this can be done quickly with one 
hand.

I like my toaster and I don't regret buying it.

 That's for "bonding".  Where do you pick up "ground" - at the

Re: [Elecraft] K4 YouTube Video List by Date

[George Thornton]

I am a happy owner of a K3 that has been partially updated to K3s standards.

I am not a contester (other than at Field Day) and it is a big financial jump 
to go to the K4.

Since my existing equipment is working so well for me, I am not likely to move 
to the K4 unless there is some degree of enhanced performance.

John, that's the beauty of it all... you can play now (or rather in the near 
future) or you can wait and decide for yourself after all the 'glorious 
independent reviews come in' (grump around like the Grumpy Old K3 Grinch who 
stole Christmas). "When I was a young man we used a K3 or a K3S and by golly we 
loved it" You young whipper snappers with your new fangled K4 gizzo radios! 
:)  Is someone making you upgrade to a K4?
Twisting your arm? You totally missed the point.

The K4 isn't ONLY about the receiver specs... maybe for you so you have no 
choice but to wait...  I get it...  However if that was the case, then you 
would have bought some other transceiver that has already exceeded some of the 
K3S's specs. No? The point here is that there is far more to the new platform 
than receiver specs alone and the potential truly leaves the exhausted K3's 
processing and now static capabilities in the dust (Elecraft is moving on 
whether you like it or not... that ship has already sailed!).
Plus sensitivity is only as good as the noise floor your antenna system 
provides... I'm not aware of an HF antenna system that provides a ~-133dBm to 
-145dBm MDS noise floor.  So sensitivity is all relative to your antenna 
system.  Blocking dynamic range is far more important to me.  It's time for 
Elecraft to move on to a platform they can build on.  I'm sure many will shake 
their fist in the air, weep and wail and gnash their teeth, holding on to the 
K3s for years and years to come (a testament to K3 success), but many will be 
excited for what the K4 will bring and are willing to go along for the ride 
right from the start.

You can stomp your feet and do what you like...bark at the moon and pound sand 
and continue to stick with the K3 until the end of times, nothing wrong with 
that... try to convince yourself that the creators of the K3 can't do any 
better.  I'm in the camp that they have already done better and I want to go 
along for that ride.  Doing better includes far more capabilities than dropping 
the MDS by a few dBm what will net nothing.
Onward and upward I say... it's exciting to see that there is and continues to 
be a market to keep pushing the envelope in the HF transceiver market.

Re: [Elecraft] K3 problem

[George Thornton]

I want to echo my appreciation of Elecraft repair service.

I had my K3 in a few years ago after it malfunctioned during field use.

They also went through it and made all sorts of additions and calibrations.

Really well worth the moderate cost and inconvenience.

The unit continues to perform flawlessly.

Jim,

In my view, that is a very wise decision.  I'm 77 yrs of age ("seasoned
citizen") with shaky hands.  After observing just how small the SMD components 
are when trying to install the K-pod mod for powering via its data cable,  I 
realized my 6 year old K3 with an annoying problem (PWR control mushy) needed 
to be sent home (aka The SPA).

What I hadn't expected was that they would also bring the radio up to the 
latest specs by installing gold pins, installing the latest firmware (which I 
thought I had done), repairing a LPA problem I didn't know I had, and 
performing all of the calibrations (my POWER reading was significantly off, 
they said).  Yes, it was a little expensive ($400), but well worth it, and my 
K3 will now serve me well for many years to come.  You will not be disappointed.

Re: [Elecraft] KPA500 - Advantage of min fan speed?

[George Thornton]

For heat transfer to another object, the amount transferred depends 
substantially on the heat absorbing characteristics of the object.   Some 
objects are natural insulators and will result in little heat transfer.  Air is 
not an insulator but it is not as effective as water, which is 24 times as heat 
absorbing as air.  

The surface area of contact is also important.  Moving air across a hot surface 
increases the exposure of cooler air to the hot surface resulting in faster 
cooling.  In other words a faster fan will always cool more than a slower fan.

Andy,

Physical fact related to any heat dissipating object -- if you apply an air 
stream across the object, it will not come up to a given temperature as quickly 
as having no air stream across it.

Specifically for the amp, if you run the fan speed minimum at 1, it will heat 
to the 55 degC threshold more slowly before switching  to level 2. 
Of course, from there on up to higher temperatures, there will be the same time 
period between the higher fan speed steps.

In other words, the fan minimum will NOT shift the entire range of thresholds, 
but it WILL delay the time to reach the level 2 threshold.

Don W3FPR

Re: [Elecraft] K4

[George Thornton]

I have a fully provisioned K3 with some of the K3s upgrades.  I have the P3 
with transmit sensor and SVGA additions.  A few years ago I had it serviced and 
everything is working nicely.  By now I am comfortable with operation and I 
have figured out how to tune things up for maximum performance.  I even have a 
Rose Kopp K3 bag embroidered with my call sign.

The biggest criticism I have heard of the K3 has to do with the quality of the 
audio.  The K3 rig is a bit shrill and harsh compared to some other rigs I have 
heard.  I have a nice pair of Sounds Sweet speakers (alas no longer made) that 
solves that issue for me.

I have looked at the K4 materials on line and I understand the multiple 
advances this rig will offer.  If I went for it I would go for the full HD 
version.  I want the maximum possible advantage in a contest situation.

But to spend 5 grand plus I would need to see some improvement in performance 
to justify the substantial additional expense.  That includes receiver 
performance as well as advances in DSP and noise reductio

I am going to hold off on ordering until I see some test reports and 
evaluations.  I will probably order next year after the kit option becomes 
available.

Re: [Elecraft] K3 PowerPole connector

[George Thornton]

Are you replacing the connector that plugs into the K3 or are you replacing the 
part built in to the K3?

If the part that is built into the K3, I would strongly suggest getting the 
part direct from Elecraft.  These have to be securely mounted within the radio.

If the part that connects, note the following:

PowerPole connectors come in sizes according to the current amperage required 
for the particular circuit.

Anderson PowerPoles consist both of the red and black housing and the crimp 
connectors for the wires.  

The housing size used in the K3 is the standard size that will fit both 15, 30 
and 45 amp crimp connectors.   You choose the connector that fits the 
particular wire size.   30 amp capacity circuits are adequate to power the K3 
and should be used.

Unless you purchase pre-assembled connectors you will also need a crimp tool to 
crimp the connectors to the wires.   There is also a small learning curve on 
how to crimp and insert the crimped wires into the housings.  

I would get the parts you need from a company such as Powerwerx.  They can help 
with any connections.

Re: [Elecraft] K4

[George Thornton]

I have been an active HAM since about 2000.  

After a brief and very unsatisfactory experience with a Kenwood 2000, all my HF 
rigs have been Elecraft and I have always gone kit.

I currently own a well-populated K3 with some of the K3s modifications.

I am less concerned about bells and whistles than pure performance.  Can I hear 
them?  Can I penetrate through under adverse conditions and get a QSL?

Elecraft has always delivered and has always been at or near the top in 
performance.

I have confidence with Elecraft that I am at the top in quality and when I 
can't get through it is not the fault of the radio.

I know this is a smart company.  It is an American company that has survived 
and excelled in a market dominated by foreign competition.  

On top of it, this is an organization that listens to and takes care of its 
customers.If something goes wrong they will help me sort it out and fix it. 
 And they will do it for a reasonable price.

I don't see myself ever going anywhere else.

Re: [Elecraft] P3 Panadapter

[George Thornton]

I have owned both the K2 and K3.  Perhaps the most fun I had in HAM radio was 
building the K2.   I learned a lot about soldering and assembly techniques.  

Electronics technology has advanced with miniaturization and surface mount 
parts.  The skill and equipment requirements for surface mount work is beyond 
the average amateur.  Elecraft does not offer kits that require surface mount 
work.

The assembly process for the K3 is much less satisfying than with the K2.   All 
circuit boards come pre-assembled and you are pretty much just building the box 
and plugging things in.  

I also have worked extensively with the P3.   I find it very helpful.  There is 
a wealth of knowledge you get from being able to visually see the spectrum you 
are working.  

That being said, some of the advantages of the P3 come from its close 
integration with the K3.  I would believe that close integration would not be 
possible with the K2.

There are also other panadapter options including the LP-Pan, which will allow 
you to view the K2's spectrum.   I much prefer the P3 because of the handy 
controls that allow you to adjust the image, but some of those other options 
may be less expensive.

Think also of where you might go with all this.  The K2 is a wonderful rig and 
more than adequate for HF work.  If yuou get really serious about this you may, 
as I did, choose to upgrade to either the K3s or KX3.  The P3 could be used 
with the K3s but the KX3 has a different, smaller unit.

Don,

You can use it with the K3 (the P3 input can be tuned anywhere between 455kHz 
and 21 MHz).
You will have to add an IF output to the K2.  DX Engineering is now selling the 
Clifton Labs buffer amplifier which can be used for that purpose.

I don't know what documentation is being sent with the DX Engineering kit, but 
if you need it, I can supply the original Clifton Labs document for the K2.

Re: [Elecraft] K4

[George Thornton]

If you are used to working large rigs with lots of buttons, I can see how the 
K3/K3s might be an adjustment.

I have found the K3 controls to be natural and appropriate.  For most of my 
operation the buttons and dials I need to use in action are right at my 
fingertips.  Once set up correctly, I find little need to venture into the menu 
system on a day to day basis.  

Sure. It would be nice to have band and mode stacks.  But is it that big a 
deal, worth spending many thousands of dollars to change?  

We will gain nothing in performance with a bigger rig.  Already Elecraft 
outperforms ALL of the big boxes on the market, per Sherwood Engineering.

Here is an elegant and simple solution for the K4 that will satisfy the big box 
demand.  

Design a modular big front panel that simply plugs into the K3.  Design should 
be relatively easy because you don't have to change the K3s itself, just add a 
command and control interface for the larger front panel.  Can you use the 
accessory port or do you need more connections?  I don't know I am not an 
engineer.  Currently computer radio control programs work with a simple DB9 
connection.  

Then give an option of mounting the K3s in a larger box.  That would have the 
added convenience of making it easier for us klutzes to be able to get into the 
rig to make changes such as adding filters.

So, you would have options:
1. standard K3s
2. Standalone large front panel.  Put your K3s under the table and mount your 
front panel wherever.
3. K3s in a larger box with the larger front panel mounted on the front.  You 
can even add options to the large box such as nicer stereo built in speakers, 
even a built in AC to DC power supply.

It will all still be the best HF radio in the world, made right here in the US.

Subject: Re: [Elecraft] K4

I'll weigh in on this a little before it gets stamped on again as being, 
unfortunately, irrelevant and pointless.

I think there is a big gaping hole in the Elecraft product line. Not in 
performance terms but more in ergonomics. A K3 has been my primary radio for a 
few years now and before that an Orion, before that a TS940,
TS830- etc etc. Performance wise there is no doubt the K3 bests them all, I 
recently built a K2 and think that's scarily good in raw performance terms as 
well. My K3 is pretty much fully kitted out and I have a P3 as well which is 
extremely useful and they're going nowhere.

 From the super small super portable super capable K2 and KX3 to the small and 
portable and no less capable K3/K3S their market segments are well covered but 
KenYaeCom have surely sold enough
TS990,FT9000,IC7800/50/51 that shows well the market demand for a quality high 
end desktop sized radio. If the pictures on QRZ are anything to go by not 
everyone operates out of a shoe box with many having dedicated rooms for their 
radio hobbies. If the shoe box is your limitation then the K3 is undoubtedly a 
superb choice but where space is less restricted a bit more in the way of panel 
acreage might well sway a lot more FT9000/TS900/IC78xx users I feel, not to 
mention those of us who just feel the K3 package is, for a desktop radio, just 
a bit too much of a compromise.

Key requirements on my end after considerable K3 usage. A better more up to 
date menu system that either removes or better, handles the myriad un-intuitive 
selections. There are a number of menu options which unless you have 
significant handbook familiarity lack explanation about additional keypad 
presses. There are even some for which software updates need to be consulted 
though that is a different matter. Some menu choices could well be better homed 
as front panel controls. The keypad is another area I find seriously lacking 
for a top end product. 
Again, great for the type of product it is but I find it lacking. Band keys, 
mode keys, a proper band stacking register, a better way to deal with the sub 
receiver settings, more, bigger and wider spaced control knobs, yes all of this 
needs panel space but that shouldn't really need to be a problem. It's possible 
the entire form factor could use a rethink, do we need a box 12 inches deep. 
Why not a front panel that is
16 inches by 6 inches on a radio that is just 5 inches deep. Overall it would 
likely be a similar volume and contain just as much under the skin. The Orion 
was probably overkill with the amount of fresh air in every box, some careful 
plug in board stacking could have reduced the box depth by half whilst 
retaining the same front panel space. A good display with all info including 
the somewhat obligatory scope and waterfall properly integrated seems a no 
brainer today I guess, of course with a port for connection of 36 inch full 4k 
displays, ideally with different screen displays.

I like the 

Re: [Elecraft] K3S - Help me decide on which options to purchase

[George Thornton]

I would add to that my comments:

I think if you are chasing DX on sideband it might be helpful to also get 
either the 1.8 or 2.1 filter.  These filters are effective at blanking out 
adjacent stations so you can hear the weaker DX signal.

I would not be afraid to go under the hood and add things as long as you don't 
have the second receiver.  In my opinion the second receiver installation is 
very tricky.  Clearances are very tight with the second receiver and 
installation is tricky.

Since you've had a K3 before, you should have some insight as to how if 
fulfilled your needs.

The radios are very similar, I have both and for the most part don't see a 
world of difference, other than the old one is more reliable.  The K3S preamp 
is better if you care about the higher bands.

I am mainly interested in chasing DX.  Because I have a KPA500 and KAT500, I 
don't have a tuner in either radio, although obviously, the old K3 predates the 
external amp/tuner.  Also, I don't have a second receiver.  You can work DX, 
even with wide splits without one.  I do it all the time.

I would recommend the 2.8 kHz filter just because the symmetry is better and 
this affects TX opposite sideband rejection.  I have a 400 Hz and a 250 Hz 
filter, only because I was given the latter. The 400 is fine for CW and optimum 
if you venture into RTTY.

If you're only interested in a couple of bands you should be able to have 
matched antennas and won't need a tuner.

If you want general coverage RX or are interested in the VLF stuff get the 
filter.  But really, installing one later is a matter of removing a few screws 
from the top cover and plugging it in.  The same is true of crystal filters 
except you have to remove two covers.  Don't be afraid of this stuff.  You have 
a ham license remember?

Re: [Elecraft] P3 vs LP-Pan / NaP3

I too had the LP-Pan before the K3.

Computers can be finicky and I found using the LP-Pan to be at times difficult 
to keep running.  I also did not find it easy to adjust the scale ranges to 
make the graphics displays optimized for what I wanted to do.

By contrast, the P3 was easy to set up and get running.  The controls used for 
ranging the display were knobs with labels and were easy to adjust on the fly.  
The integration with the K3 was a further plus.

Re: [Elecraft] Antenna Analyzer

[George Thornton]

The Time Domain Reflectometer (TDR) is a hugely important feature, and is now 
available with other brands, including some of the RigExpert models.

I do a lot of field work with both HF and VHF/UHF.  In my experience most of 
the problems I have encountered have been traced to cable defects of one kind 
or another.  The TDR function allows you to quickly and reliably test the 
integrity of cabling, allowing you to identify the exact location of the defect.

I am partial to the RigExpert models, which have been reliable and accurate, 
and very easy and intuitive to use.  

My only quarrel with RigExpert is that they do not offer water resistant sealed 
cases.   These can get damaged in a wet environment.

I was introduced to the SARK-110 several years ago and besides being an 
excellent antenna analyzer, it had one feature that nobody else had (when I 
bought the SARK) and that is called a "Time Domain Reflectometer".  This allows 
you to find breaks, impedance bumps and other anomalies in cable runs.

During my 20 years in the Army, I was introduced to a hugely expensive HP-140A 
oscilloscope with a TDR plug in.  We used it to find cuts in our buried coax 
where the local people were digging it up for the copper (back in 1967).  From 
that point on, I always wanted a TDR but they were way too expensive (even 
used) for a poor ham to even consider until I was introduced to the SARK by a 
good friend at the "OzarkCon" QRP convention.  It paid for itself quickly by 
finding where a gopher (or
mole) had chewed mostly through some buried coax I had going to a vertical in 
the back yard.  The SARK's TDR pinpointed the break within a foot and it was 
probably more accurate than that as my measurements when following the cable 
were somewhat sloppy.

It also makes a pretty decent signal generator as well, can be calibrated 
against WWV with not too much effort, but the minimum signal you can output is 
50 microvolts (S9) so a good external step attenuator is needed along with 
double shielded cables to minimize feedthrough of 
the SARK's output signal.   Oh yes, I did mention, it's an excellent 
antanna analyzer as well and it will do Smith Chart plots and other stuff too.  
You can control it with a computer via USB too.

No financial interest in the company, just a very happy user.

[George Thornton]

I don't live in California but I have driven all through the area.

Elecraft is located near the coast north of Monterrey and south of Santa Cruz.  
This is as I recall very roughly 50-100 miles south of San Francisco and a 
couple hundred miles north of Los Angeles.

Most of the fires are either in the California wine country, which is north and 
east of San Francisco, or in southern California, near Los Angeles.

Watsonville is itself located in a valley and there is probably relatively 
little vegetation in Watsonville itself to fuel a fire.

This area involves the beginning of a climate transition zone.  Southern 
California can get very dry along the coast.   This area is high risk for fires.

The north/central California coast is heavily influenced by cool, moist marine 
air.  The forests in this area tend to be relatively wet and fires are more 
rare.  For example, in San Francisco, temperatures can be 20 or more degrees 
cooler than in Oakland across the bay and dense evening fog is common.

As you go north in California into Oregon and Washington, where I live, forests 
on the coast get wetter and denser.   Forest fires in the coastal areas are 
extremely rare and unusual.  Conditions are almost always too cool and wet.

In central/northern California, Washington and Oregon fires tend to happen in 
the drier, inland areas.

I hope all of the Elecraft personnel are safe from the fires. I am not sure

Re: [Elecraft] K3S Kit issue - Does not transmit in SSB

[George Thornton]

I would start by bringing your tests down to the basics and eliminating any 
possible computer software configuration cause.

I would first re-load the firmware and re-run calibration.

Assuming those all work correctly, the next issue is to properly configure the 
microphone settings.  There are several things that have to be correct, 
including where the microphone is connected (rear or front), the nature of the 
microphone, any bias and the proper microphone power setting (hi or low).  Read 
the manual and follow the instructions.

If you are still having problems, test with another microphone to make sure the 
problem is not with the mic.

If none of those work I would call the factory for further guidance.  They are 
excellent at diagnosis and are very helpful.

Subject: [Elecraft] K3S Kit issue - Does not transmit in SSB

Good day,

I am adressing this issue to this forum as I am puzzled and don't know what
to do.

Basically, I assembled my K3S kit about a month ago, no issues with the
build and initial testing. I have done all of the required calibration and
even the RF Gain calibration using the XG3 signal generator.

Everything worked out fine, I was able to receive signals and hooking up my
paddle I was able to transmit in CW. Since I have the TX Monitor option, I
was able to see the signal and power output on the P3 display. I did put
back the radio in his box and put it aside for about a month as I was busy
with other family issues (i.e. a new baby).

I pulled back the radio last week as I wanted to play with the digital
modes, after fiddling with the settings I was able to hook up the computer
and the radio using the USB cable to use the internal sound card and
control. I am able to receive signals on my computer, I can see the received
signal on the computer display so I have no doubt that the sound card
drivers are working. I configured the software to control the radio and when
I start to transmit using the software, the radio turn into transmit mode
and the TX red LED lights up. However, looking on the P3 Display using the
TX Monitor, I see no signal being transmitted, if I increase the Monitor
volume, I hear a hissing sound and there is no power output.

Since I initially thought this was caused by a setting, I hooked up the MH2
microphone and pressed the PTT, the TX LED lights up, but when I speak in
the microphone, no signal appear on the TX Monitor, same hissing sound when
I increase the Monitor Volume and no power output.

Does anyone have faced such an issue? Any idea what is wrong?

I have assembled many kits helping other people (K3, K3S, KX3, PX3) and
never faced any issue but for my kit, I dont get it.

Thanks in advance!

Re: [Elecraft] K3s Carry Bag

[George Thornton]

I have been using cases like that to transport my K3 to Field Day for a number 
of years.  Although I thought I was being very careful I found that the radio 
sustained damage to some of the parts that stick out, specifically the SO239 
connector and a knob in the front that cracked.

I now use the Rose Kopp DXpedition case, the one that includes custom dense 
cell foam padding to protect the protruding parts on the front and back.

I would also think a hard Pelican type case with removable foam sections is 
another good way to protect your investment.

Given what we pay for this stuff, If you are going to move this around a lot 
for Field use, I would argue in favor of maximum protection.  The cost of a 
single repair trip to the factory is going to exceed the price of the best 
protective case.

Re: [Elecraft] Frustration with Elecraft

[George Thornton]

I want to strongly echo others' statements of confidence and support for 
Elecraft's quality, integrity and follow through.

I started with Elecraft by building a K2 (great kit building experience) and 
later K3/P3 with all the bells and whistles.

These guys make excellent products and they provide top notch service.  They 
stand by their customers and their products.

Electronic equipment is complex and sensitive and occasionally components 
malfunction or become damaged.  These things are easily corrected.

True "noise cancelling" mics sound awful. They work on the principle of
cancelling noise more than an inch or two from the mouth. SUPER noisy
places like aircraft are the ONLY place to use them.

Most hams who have too much background noise either don't work the mic
close enough (it should be an inch or two above and alongside the
mouth), or have processing and/or mic gain turned up way too high.

Re: [Elecraft] K3 Display is Dated. . .

[George Thornton]

I agree with this assessment.

I like the Elecraft solution.  The K3 screen gives you clearly and simply what 
you need to know at a glance.  No fuss and always there for you.

You want a screen with a lot of other information including a band scope, put 
it in a separate box.  That leaves you free to innovate and add features as you 
want without tampering with the main information screen on the K3.

Most importantly make it reliable and make it work practically without the need 
to add a computer to the mix.

With all due respect, I think the K3/P3 is a classic design, including the
man-machine interface. Not a square nanometer of wasted real estate,
everything is where I need it the most and when I need it quickly.
Graphics, interactivity, not too much, not too little, just the right
touch. It is quite clear that a great deal of thought and iteration went
into laying it out. In that sense, it's like my Collins S-Line, another
obviously well thought-out intuitive classic design that is a delight to
operate. So bedecking either of these with a multicolor touch screen is
not something that appeals to me personally. Jim Ewing N4TMM

my mind is using the tiny knob to QSY... Full mouse support would be welcome.
I've found that the small screen works better than anticipated, so have not 
added the SVGA option. Maybe someday.
Another worthy contender is the built in SDRPlay support in Win4K3 Suite. It, 
too is pretty much plug and play, and gives you the point and click mouse 
support. I have mine connected to the IF output of the P3, and can use them in

Re: [Elecraft] Elecraft insurance rate?

[George Thornton]

I have not looked at this in recent years but it used to be you declare value 
so the shipper can set rates for insurance.  They are going to charge more for 
something that is hugely valuable.

To me the problem is not so much damage in transit but loss of the package.

I have had two incidents at my home where things went awry.  In one case they 
said a package was delivered, but I never saw it.  On another occasion (just 
this week) a package was left at the wrong address.  Fortunately, my neighbor 
saw that and brought it over so there was no loss.

There is less risk of a package being misdelivered when a signature is required.

If a package is misdelivered, who is to say what happened.  The shipper will 
not admit to misdelivery, and it may come down to a mysterious criminal 
stealing it from your doorstep.

Hi,

I am aware of the UPS calling their insurance "declared value". Can somebody
enlighten me as to what it means? Literature by UPS is very adamant that
"declared value" is not insurance. Then exactly what is it? My expectation
is that if the package is damaged or lost I will receive fair compensation
up to the "declared value".

On the topic of Elecraft's new insurance charges, I have been told by
somebody at Elecraft in the past that they are "self insured". I take that
to mean that they will take their chances and absorb the loss if a package
is damaged or lost. It may very well make economic sense for large shipping
volumes in the long run. BTW I have *never* have anything shipped to or from
me damaged or lost. Not even a scratch to the shipping carton. So the notion
of UPS strongmen tossing packages around must be a myth. The same thing goes
for the post office. It has become a very competitive parcel service in
recent years.

Re: [Elecraft] Sub Receiver & KBPF3

[George Thornton]

I have built several kits of all kinds going back to Heathkit days and I built 
my own K2.

I had a lot of problems with the sub-Rx installation.  I have big hands and 
could not seem to be able to see to line things up properly, not to mention the 
pesky TMP connectors.

I am at the point with this where I will no longer attempt any mod that 
requires removal of the Sub-Rx.  Everything goes back to the factory.

Re: [Elecraft] Help me choose my first HF rig

[George Thornton]

My experience was different.

My first HF radio was one of those that had all the features including VHF/UHF. 
 I thought it was a good buy at under $2000 because it was so versatile.   I am 
not naming radio names.

The problem is the receiver on that rig was absolutely horrible.  As a new HF 
operator in an urban location, I already had a handicap because I did not have 
a top quality antenna.  End result was the HF operation on that rig proved 
mostly useless.  I ended up selling the rig after about two years, complete 
waste of money.

I would say that, looking at Sherwood Engineering test data, any of those rigs 
in the first 10-20 is going to perform more than adequately for casual use.

New HAMS often waste a lot of money on purchases they later regret.

I have never been dissatisfied with any Elecraft purchase.

Best advice so far, Lynn. To the OP: Get something, then GET ON THE AIR.
Nobody learns from reading specs and opinions. It isn't the way to find
your first rig, and probably wasn't the way you picked your first
girlfriend. Play the field. The learning starts when you take the
plunge. You'll know what you want out of the next rig.

Good used rigs aren't expensive, and if you buy wisely, you can get most
if not all your money back for the next rig.

Re: [Elecraft] K3 loss of rx signal

[George Thornton]

Exerting too much force with PL259’s can put stress on the radio SO 239 
connectors, I have had some of the internal mounts work loose over time.

Top quality Amphenol connectors are more precisely machined, fit better and are 
much easier to work with.  I don’t get failures with these and hand tightening 
seems to be sufficient in most situations.

Lordee, I've seen, done, and heard of these things so many times...

PL259 the worst offender, with BNC close second. Mini-coax TMP in a
class by itself.

On the PL259, if the teeth around the edge of the mating shell aren't
aligned to move down into the teeth of the SO239, you can "tighten"
the PL259 to what seems tight, but a temperature change or a jiggle
will let the teeth align. The connector is now loose. A variety of
"false snugs" can occur with PL259, barrel, SO239 that have been
outdoors and gotten stuff in threads.

BNC's, if not inserted straight on, can seem snug, but not go down all
the way. Then the twist shell can go a distance and won't seem to want
to go any farther. It's very easy to not have enough finger strength
to twist the shell enough to go all the way down.

Mini-coax TMP connectors are bad because if the center pin does not
match inside the socket it won't go down and cause an infamous
intermittent that many have experienced. The flares on the male TMP
have to go down until they are prevented from further insertion by the
socket.

Re: [Elecraft] K3 Stops Transmitting (solved)

[George Thornton]

I have written about this before.  I have had similar problems at Field Day, 
and some friends of mine have also had issues while in mobile contest use.

>If there is any issue with the power supply itself, or if the cables between

As an example, I have an Astron power supply mediated through a PWRgate device 
and a separate power distribution panel.  When I route my K3 power this way, I 
can see a drop of as much as one volt or more of input voltage according to the 
K3's internal voltage meter when I transmit.

On the other hand, using a short run of thick gauge wire direct from the PS to 
the K3, the voltage drop is only .1 or.2 volts.

My friend had problems in mobile use in a contest going from the vehicle 
generator (motor on) to car battery.  He ended up installing a voltage booster 
device to get solid performance.

When this happens I was able to restore function by reinstalling firmware and 
recalibrating the transmit power.

Subject: [Elecraft] K3 Stops Transmitting (solved)

A couple of weeks ago I posted that my K3 suddenly stopped transmitting
during ARRL CW.
The PTT would enable, it was not in TEST mode, the CW monitor would sound,
but no output.
Pushing the TUNE button would result in "0 watts" showing on the display.
The problem persisted after I power cycled the radio, plugged/unplugged the
DC source, tried various control changes, and a soft "drop" test. Through
all of this, the Rx worked just fine. Nothing restored the radio
transmitting ability. So, I swapped it out and continued the contest.

When I got home, I hooked the radio up and it transmitted just fine.
Something happened that
stopped the radio from transmitting, but now it worked fine. So I posted my
experiences here and asked for suggestions.

A number suggested the DC power supply cable. My experiences at the site
suggested that wasn't the culprit. A number suggested that I had somehow
put the radio into "TEST" mode, but I was sure I had not. I even toggled
into and out of "TEST" mode several times, but that didn't solve the
problem. Several suggested that a voltage had been applied to the Inhibit
pin of the ACC15 connector, but there was nothing plugged into the ACC15
socket. Two suggestions seemed most plausible: that one of the coax cables
from the new synthesizer to the other boards was intermittent, or that the
Sub Rx plugs was intermittent.

Once I had a place to look, I opened the radio and did the following:
1. Took a pair of long nose pliers and GENTLY rotated and firmly seated each
coaxial cable connector connecting the synthesizer board to the rest of the
radio.
All seemed to be secure
and in tight, but they were all rotated just a little.
2. Checked the seating of the Sub Rx into its connectors. The back
connector was not fully
seated- I'd say it was about 80% seated, but there is a little play in the
connector. It is now fully seated.

Since then, I've operated the radio about 30 hours in contesting. The no
transmit problem has not come back. Did I fix it? The problem had never
happened before, I don't have a clear problem that was solved, but it has
made it 30 hours now without a problem. At least for now, I feel the
problem has been solved.

Re: [Elecraft] K3 Power Supply Question

[George Thornton]

I am using an Astron 35 amp ps.

I did not use a dmm, just the meter on the k3.  I only got a .2 drop when I 
connected direct with a five foot thick gauge wire.  But using the same pwrgate 
setup as yours it dropped a full volt or more on transmit.

A friend had problems running in a mobile setting with battery backup he went 
to a voltage boost regulator and it all works.

From what I am learning the K3 needs a strong, stable power supply to be 
reliable.

Subject: Re: [Elecraft] K3 Power Supply Question

I put my DMM leads on the front terminals of the 4545 and with key down, no 
change at all: 13.9V, so it appears that MFJ gets a pass on this one.

To do my testing I had run the 4545 directly to the K3 and not through the Rig 
Runner. However, to do that I had simply hooked the cable from the 4245 that 
used to go to the Rig Runner into the end of the cable going to the K3, 
basically taking the Rig Runner, Power Gate, and Boost Regulator out of the 
picture. This gave me two cables, total of about 10 feet, with three APP 
connectors.

Thus the connection went from the 4245 through a five foot cable and some 
ferrite donuts into another five foot cable to the back of the K3. The voltage 
dropped to 12.5 on the K3 meter. With some work, I pulled the cable out of the 
K3 and connected the 4245 cable with the ferrites directly into the K3. With 
this combination (only ONE cable and Power Poles at the K3 end) the voltage 
dropped from 13.9 to 13.1. This means that a second five foot length of cable 
and two APP’s caused a loss of .6 volts.

So, what does all this mean? Since I am not using wimpy, skinny wire I have to 
conclude that perhaps the APP’s might be the cause of some of this voltage 
drop. With the original configuration I had using the AGM battery, Power Gate, 
Boost Regulator, and Rig Runner, there are a bunch of APP’s in the circuit, in 
addition to several feet of wire. I “could” simply connect the 4245 directly to 
the K3 and settle for a drop of .8 volts (13.9 to 13.1), but that kinda defeats 
the purpose of having a solar / battery backup system and a power distribution 
system. I thought this issue would be solved by replacing the MFJ PS with 
something else, but it is looking a LOT more complex at this point. Crap - what 
is one supposed to do?

I had something somewhat similar happen and the best I could tell it was

Re: [Elecraft] Augment KX3 or buy K3?

[George Thornton]

To amplify this answer, the dual-receive and filter options available only on 
the K3S are valuable tools for penetrating pileups.  The dual receive also 
allows for diversity reception, which can improve your ability to pick out a 
weak signal from the surrounding noise.

I did not know the PX3 has the same size screen as the P3.  The P3 does have 
additional optional features not available with the PX3.  These include the TX 
monitor and the ability to put the image on a larger screen (SVGA option).  I 
have both of those optional features and I find them very useful.

If you are into contesting or DXing or otherwise dealing with pileups,
then the K3S is in order for you.

If you operating is a bit more casual than that, then add the KXPA100

Re: [Elecraft] Augment KX3 or buy K3?

[George Thornton]

I have had the opportunity to work both options on Field Day.

The KX3 is a nice rig and it performs very well.  When you add the amplifier 
and PX3 you have a completely workable setup that has the added advantage of 
extreme portability.

However, the K3s has a number of features and capabilities that don't come with 
the KX3.  You have greater options for filters, dual receivers, digital modes, 
etc.  The P3 has a larger screen, and it can connect to an external monitor.   
The KX3 by comparison has relatively weak audio and would benefit from either 
amplified speakers or headphones.

I would say that if you are considering contesting, then the K3s is the way to 
go.  IF all you want is casual use, the KX3 with amplifier is plenty of radio.

Subject: [Elecraft] Augment KX3 or buy K3?

Hi all
I am in the fortunate position of having some money to spend upgrading my
station; however I'm torn between two options.

I have a KX3 which I love and use a lot as a base station and also for
SOTA. Generally, I operate with 5W max but there are occasions where I'd
really like more power: but no more than 100W.

My options at present seem to be:
1) Reserve the KX3 for SOTA and buy a K3S, (but nothing more I only have
enough for a K3S)
2) Add a KXPA100 with ATU (and maybe a PX3) instead.

If this were you with money burning a hole in your pocket, which of these
two options would you go for?

Re: [Elecraft] Compare the K3 and the Icom IC-7300

[George Thornton]

The current Sherwood Engineering receiver test data list includes all of these 
radios.

In the latest figures, the K3 (old synthesizer) rates above both the 7300 and 
TS590G.  The 7300 is down 5 in the list from the K2 and the 7300 is two above 
the TS590G.

If you just installed the upgraded synthesizer you would improve your K3 by 
five spots.  In fact, only the full K3S and Flexradio 6700 are currently better.

However, for casual rag chewing I would think any of these transceivers would 
be just fine.   It would be a matter of personal preference.  I know several 
people who are very happy with the TS590G.

These are all quality rigs.

ARRL reviews most new rigs, but I don't see one for the 7300.

For the way you operate, If I were looking for a lower cost backup for a
K3, I'd look at something like the TS590SG. A friend who's a great
operator owns one and likes it, and ARRL lab test data for it is quite
good considering its price.

Re: [Elecraft] P3 "Point and Click"

[George Thornton]

I have used both.  I much prefer the P3.

The LP-Pan is tricky to set up and configure, and computers can be balky and 
unreliable.  Adjustments can be tricky and counterintuitive, and require 
specialized knowledge of how the particular program works.

The P3 is a plug and play device.  Adjustment is via various labeled tuning 
knobs and becomes pretty easy with a little practice.

In fixed mode the P3 can easily and directly tune to an interesting point on 
the band.  Just rotate the knob to bring the cursor into position and press the 
button.  Just as fast as a mouse.

Re: [Elecraft] Full kits,

[George Thornton]

Constructing my old K2 was one of the most fun and challenging things I have 
done with electronics.  Before that I built a few things long ago with Heathkit.

Top end modern transceiver technology has moved beyond the K2, which is why 
Elecraft did a complete redesign with the K3 and K3s.   The K2 is a nice rig, 
but the K3s is so much more.

Modern electronics is all about miniaturization.  Nearly all the components are 
smaller, they have to be installed at the surface instead of via through-board 
solder holes.   The result is that you can now create transceivers that have 
top notch performance yet fit in the palm of your hand.  Witness the K3s and 
K2s.

To work with miniaturized surface mount components you need specialized 
equipment and specialized skills.  A simple $100 soldering station and some 
rework tools is no longer good enough for this kind of work.  There are 
relatively few amateurs who could or would tackle a kit where the great 
majority of the components are tiny and surface mounted.

I imagine Elecraft could re-engineer the K3 with non-surface mount parts.  I 
imagine the box will have to be a lot bigger.  Same performance?  Perhaps, 
perhaps not.  That will be a significantly different beast.

I think the added cost of re-engineering would probably make the kit 
prohibitive.

There are still kits around, and smaller projects are still reasonable using 
traditional construction methods and parts.  However, the era of 
solder-your-own kits is definitely in decline.

Or we could all lease some equipment and learn how to surface mount.

Re: [Elecraft] Considering KPA500/KAT500 Combo with Flex 6500

[George Thornton]

I have toyed with the idea of moving up to an amp.  My problem is I live in an 
urban location with houses close together.  I am concerned that with too much 
power I might start lighting up the neighbors' TV's and computers.

I think the best money invested is in the antenna.  I got a used 3 element 
SteppIr a few years ago, paying about what it would have cost for a KPA 500 by 
the time I added a rooftop tower and used rotor.  I have been very pleased with 
what I have been able to do using 100 watts and that antenna, and I have found 
only a few situations where power would have helped me.

Of course, now we are down in the solar cycle and I am now looking at what I 
can do to improve low band performance.  I am contemplating a 43 ft vertical 
and a SteppIr DB 18e.

I have owned pretty much only Elecraft over the past decade and a half and I 
have been well pleased with the quality of their equipment.

Subject: [Elecraft] Considering KPA500/KAT500 Combo with Flex 6500

Hi... with all the hoopla over the new $7K Flex amplifier I was feeling a
little power envy so went on a search for options. I own an Elecraft KX3
and absolutely love the rig quality so I'm thinking about the KPA500/KAT500
combination assuming I'll get the same quality equipment.

Is anyone running this combination with the Flex 6500 who might share their
thoughts, configurations, hints & kinks?

I'm thinking the combination makes sense for me because (my decision
points):

1) Being a low power operator, 500 watts seems a lot more manageable than a
nuclear powered 1.5 KW setup. It seems like a good, safe step.

2) No electrician required. I think I can run it off 110 VAC already in my
shack.

3) If I understand correctly, there is little or no integration effort
required. I'm looking at putting it inline with the RF path and adding a
PTT connection. Voila.

4) The KX3 is able to easily tune my 600 ohm ladder line fed (via 4:1
BALUN) 80 meter dipole on any band so I would guess the KAT500 wouldn't
have an issue.

Is there a reason I shouldn't consider this setup with the Flex? The only
other thing that caught my eye was the ACOM 1010 which would also require
an external tuner.

Re: [Elecraft] No Output from K3S on WSJT MSK144

[George Thornton]

I am not sure I understand your problem, and therefore my potential solution 
may be irrelevant.

I experienced sudden extremely low power output recently during a contest.

The solution was to re-install the firmware and recalibrate TX power.

I later determined the cause was voltage drop coming from the power supply.  I 
fixed loose connections in my power supply and put a short lead from the supply 
direct to the K3 and things are going well again.

Problem fixed at zero cost.

Re: [Elecraft] power issues

[George Thornton]

I did some checking today on my voltage to the K3 using two different routes.

I am using an Astron RS-35m power supply.  It was tuned up to output slightly 
under 14v.  Normally it mediates through a PG40s backup and switching device, 
connected to three 140AH backup batteries as well as the power supply.

When I connect the K3 power through the PG40S distribution panel I read 13.3 
volts at the K3.  This drops significantly when I transmit, going down to under 
12 volts.

I then direct-wired the K3 lead to the Astron using ten gauge wire and a 
relatively short lead.  Power at the K3 then reads 13.8 and drops only to 13.7 
during transmit.

Since I had failures attributed to erratic power supply, my conclusion is the 
K3 should only be run via a short, large gauge lead direct to a power supply in 
good order.

Re: [Elecraft] K3 - stuck at MCU LD we upgrading software

[George Thornton]

The history of my Astron 35 metered power supply is that it has been moved 
around a lot because I have brought it to Field Day for multiple years.

I took it apart today and found that although the connection between the power 
leads and the bolts was tight, the connection between the bolt and the housing 
of the power supply had worked a bit loose over the years.   I took things 
apart and tightened the connection between the case and the bolt.

It is all back together and working fine.  I also have a direct connection 
between the PS and the K3 using thicker wire.

The K3 is working fine right now.

In the past I suffered loss of transmit power although RX was fine.  I don’t 
remember the error message but I think it was ERR DSP.  With every failure 
reloading the firmware and calibrating power cleared it up.   The information I 
had was that this error can be associated with erratic power supply issues.

Jimmy,

You should see little voltage sag on transmit, especially at QRP levels.

Compare the voltage directly at your power supply terminals between
receive and transmit. If it stays up, then check your power cable to
the K3 for adequate size wire and good connections. If you have a DC
power distribution device like the RigRunner, remove the K3 from it and
connect direct from the power supply to the K3.

OTOH, if the voltage at the terminals droops during transmit, open the
power supply cover and remove the bolt terminals - clean the solder lugs
on the inside and the bolts, then reassemble making certain the bolts
are tight. If those bolts turn even a little bit when tightening the
external bolts, they are not tight. You must have tight connections at
the power supply.

Hi Jimmy,
Tnx for the info. I have a 35A switcher that loafs along. As I never have both 
K3's transmitting at the same time I am not taxing the supply.
W3FPR got me on the correct track.

In your case, di d you check the voltage on the K3? Maybe you had a problem 
with a connection in the power supply? Down in the Caribbean periodically we 
have to take apart the Astron linear power supplies and clean the contact 
surface on the two bolts feeding the 12V output. They develop a little bit of 
resistance that drops the voltage under a load.

Tony,

I used to have this problem all the time. It was maddening. I never knew if the 
rig was going to turn on. It was always necessary to restart my computer to get 
my K3/100 to talk to the app that resets the firmware. I had several 
suggestions to fix the problem. The one that proved most helpful was to get a 
different power supply. I was using a big Astron supply feeding into a Johnson 
power strip. Several devices ran off the power supply. It should have been able 
to supply plenty of power for everything because the other devices were low 
wattage users like a keyer. Anyway, I had a smaller Anstron device that was 
once used with a 2-Meter radio. It was fully capable of 100 watts. I hooked it 
up and the rig as a dedicated supply and it has worked perfectly ever since. 
You may have a different problem than me but that’s my story.

Re: [Elecraft] Mysterious intermittent failure possibly related to power supply?

[George Thornton]

The long history was that a few years ago I lent the rig for Field Day use and 
something unknown went wrong.  There was a nut that came loose inside the rig 
and there might have been a short circuit somewhere.

The rig was sent back to Elecraft for diagnosis and repair and it was fully 
worked over including all the mods including gold pins.  It came back fine and 
I did not open the case between then and this year's Field Day power transmit 
failure.

After Field Day I re-flashed the firmware and recalibrated transmit and it 
worked fine again although it did not get heavy use as my main antenna was down 
for servicing.

The synthesizers were upgraded about two weeks ago without a problem.

George,

Does your K3 have the gold PA pin upgrade?

Are the nuts on the filter cap studs that mount the circuit board tight?

Re: [Elecraft] Mysterious intermittent failure possibly related to power supply?

[George Thornton]

I have been having some mostly transmission issues that I suspect might be 
related to the power supply.

The issue is intermittent failure of the K3 to generate full power on transmit. 
 It operated fine for an hour or two at Field Day but suddenly we were QRP on 
my k3/100.  No error messages, just would not deliver full power.

When I got home I was told to re-install firmware and calibrate transmitter.  
Did that and everything worked fine again.

Yesterday while working on getting a new installation of PACTOR running I got 
an ERR DSE message which is solved by, again, re-installing firmware and DSP.  
Again, it ran after the K3's software was refreshed.

>From what I have seen errors like this could be traced to erratic power supply 
>issues.

My power supply is a 15 year old Astron RS-35M.  I adjusted the operating 
voltage up a bit as I am also using a PWRGate PG40s to mediate charging of some 
gel cell storage batteries.  I usually leave the Astron on all the time.

My K3 is currently wired direct to the Astron with heavier gauge wiring so I am 
getting power direct from the Astron with no mediation through batteries or the 
PWRGate.

Anybody have any thoughts to what might be going on?

I have a K3 in the 3900 serial number range, running latest (non-beta) 
firmware.  K3 has most of the bells and whistles including sub receiver and has 
been upgraded with the new synthesizers.

Re: [Elecraft] K3 won't power up

[George Thornton]

I have a k3 that was working fine but now will  not power up.

I had lent the unit to someone to use at Field Day.  They reported it would not 
power up.

Going through the unit it appears  that a nut and washer has come off of one of 
the PL259 antenna plates.  A thorough internal inspection found a loose washer 
but no nut.  

There is nothing evidently wrong inside, no flashing, no sparking, no burning 
odor.  It just won't come on.

Fuse did not activate.

I am going to call the factory tomorrow but anyone have any ideas?

Re: [Elecraft] Antenna choices

[George Thornton]

I have tried a number of different things over the years.  I have finally 
settled on a 3 element Steppir.  I got it used and paid half the cost of new, 
so it was not exorbitant.  With a little care they can be made to function as 
good as new.

The 3 element stepper and K3 are a potent mix. I can get pretty much everywhere 
and am able to get through most pileups with 100 watts,   I find I really don't 
need an amp.  

The 3 element is infinitely tunable and will give  you near perfect performance 
on all bands 40 and above.  You can add an inverted V under the tower to get 
down to 80 meters.  

You will need a rotor.  You don't need a huge investment however, they work 
well with the commonly available Ham IV rotors.  Lots of reliable and 
attractively priced used ones on the market.

I would put my money into the antenna instead of the amp.

 Multi-band Yagi antennas are multi-band, but not wideband. They are tuned for 
 specific bands, like 20m or 15m. They do not work well on bands they are not 
 designed for.
 
 A vertical on a tower might give a few dB of gain (on the bands it is 
 designed for). A Yagi (beam) will typically give 10dB or so of gain on each 
 band it is designed for.
 
 The G5RV works for a lot of people, but it is a compromise on many bands, and 
 could cause problems when run with high power (500W).


 
 Since you are going to the bother of putting up a tower, I'd also put up 
 dipoles cut for most of the lower bands and feed them from a common point. 
 This is called a fan dipole or parallel dipole. If you'd like that pre-cut 
 for you, I recommend Hy-Power Antenna (http://www.hypowerantenna.com/).

Re: [Elecraft] The Final Build and order for K3

[George Thornton]

I would have only one word of caution with respect to filters.

Replacing filters with a single receiver unit is fairly easy.  However, the 
process is more tricky when you have a sub receiver involved.

I personally found the sub receiver unit very tricky to install.  The 
clearances are tight and it was very hard for me to see if things were aligned 
correctly.  There are also a lot of tricky cable connections.Although I 
have built several Elecraft kits I still don't feel comfortable removing or 
installing the sub receiver unit.  

To change any filters you have to pull the sub Rx unit.

 Hello all,
 
 Many thanks to all that answered my many questions, and gave a new

 I have decided to order a new rig based on what was said here, about a
 30 minute conversations with a fellow named Dave at Elecraft, and that 
 eham gives it a 4.9 rating, which is hard to get there...  I tend to 
 take eham reviews with a grain of salt, but darned few radios get 4.9 
 there.
 
 If I missed sending anyone a thank you note, please forgive me, the 
 number of answers I got was phenomenal, and I think I got everyone, 
 but is would have been easy to miss someone.  So thanks to all for 
 your help in this.  It made spending 5K almost fun...  Almost...  :)
 
 Here is the final build as I will order it as soon as Dave from 
 Elecraft returns my MARS modification call.  I don't know if he gets 
 commission, but I want to be sure to order through the fellow that 
 helped me there at Elecraft.
 
 Final Build:
 
 Radio:
 K3/100-F  K3 basic radio 100W version
 KAT3-FK3 ATU unit
 KBPF3 K3 General coverage RX module for main radio
 KRX3-FK3 second rx
 KBPF3 K3 General coverage RX module for sub radio.
 I am a MARS member, and want General coverage on both
 KDVR3 Voice memory unit
 
 Filters:
 KFL3A-400 One for each radio, main and sub
 KFL3B-FM  FM Filter for main radio
 FILTERStock 2.7 KHz for both radios, main and sub
 
 Misc:
 P3-F  Panadapter
 KXV3A K3 RX Ant, IF Out  Xvertr Interface
 KUSB  Factory USB cable.
 
 Why two KBPF3's:
 Someone had mentioned that I probably did not need the second KBPF3, 
 and for the most part that person was correct, but for my MARS operations...
 I do some very odd splits sometimes, sometimes neither side being in 
 the ham bands, so the second RX was needed.
 
 Filters:
 During these entire process I had to tell myself these are roofing
 filters-- remember, these are roofing filters-- these are not bandpass 
 filters these are not band pass filters...  Remember...
 
 Many people pointed that out to me, and for that I am thankful, you 
 all saved me a few bucks...
 
 I spoke to Dave at Elecraft, and he indicated that adding filters 
 later should not pose a major issue for me, based on my experience.  
 That said, I can order filters later, and probably will, as I need 
 them, or discover I wish I had ordered them to start with.  Remember, 
 these are roofing filters...
 
 I ordered the FM Filter as opposed to the AM filter, because it is a 
 roofing filter, and several folks suggested it as it lets me do AM and 
 FM, as opposed to if I ordered just the AM filter.  I would then need 
 the FM filter later, if I did FM.  This allows both modes with one 
 filter.
 
 USB Cable:
 I ordered the cable from Elecraft because I trust they have done 
 testing and clearance of this cable, and that it will work.  I am 
 running Linux as my major OS, and I can not say enough to thank the 
 folks at Elecraft for including the utility program for Linux users...
 
 Panadapter :
 I can't imagine a radio without an Panadapter anymore...  The thought 
 is abhorrent to me.
 
 Again, many thanks to all for your help in this!!  I would feel as 
 confident I ordered correctly if it had not been for this mail list, 
 and the kind users on it.

Re: [Elecraft] Antenna question

[George Thornton]

This might be a stupid question, but here goes.

I have a small lot.  I currently am using a 3 element Yagi that barely fits on 
the property.  I was thinking about getting a vertical as a second HF antenna.  
If I put it up it is going to have to be pretty close to the Yagi.

I have a dual receive K3.  If I have both receivers going, one on each channel, 
and I broadcast on one of these antennas, am I in any danger of overloading and 
frying the other receiver?

Re: [Elecraft] A confession

[George Thornton]

I have had my K3 for about four years.  

The unit can be intimidating at first to a new user.  The menu system is 
massive and at times scary.  The microphone gain and compression have to be set 
correctly if you want to get through a pileup.  There are a few other operating 
tricks that help improve performance that can be picked up on this reflector.

In my experience the menus almost never need to be touched.  Everything needed 
for effective operation is at your fingertips on the front panel controls.  
Operation has become simple and intuitive for me.  

As far as firm upgrades are concerned, those are extraordinarily easy and 
straightforward if you stay away from beta versions.  The software update 
program is clear, straightforward and automatic, just tell it to update the 
radio and let it alone until it is done.  

This is a wonderful, effective and well-designed piece of equipment.  You 
already have it, get it out and enjoy it.

Re: [Elecraft] P3 freezing

[George Thornton]

A short while ago I reported my P3 with SVGA would freeze up from time to time.

Following recommendations on this reflector I have solved the problem.

The freeze only happens when set on maximum screen resolution.  I dropped the 
resolution by one level and everything works like a charm.  The second highest 
resolution is more than adequate.

I am not an engineer, but I suspect the problem has to do with the ability of 
the P3's hardware to keep up with all the video calculations at maximum 
resolution.

Re: [Elecraft] P3 svga hangs

[George Thornton]

I have the following setup:

K3 (with two receivers)

P3 with SVGA

Steppir 3 element Yagi 

External monitor attached to P3

I am having problems with the P3 SVGA being sluggish and periodically locking 
up.  Sometimes the external monitor locks up, sometimes both.  I can usually 
get it running by turning the P3 off and on.  This happens fairly frequently 
and can be quite annoying.  The impression is the P3 SVGA is overloaded and 
can't keep up.

The software is all up to date.  

Everything else seems to be working just fine.  

Any help would be appreciated.

Re: [Elecraft] Microphone for the K3 questions

[George Thornton]

I have the QC2 Bose headset, the Yamaha CM500 everyone recommends and the MH2.  
I work mostly SSB.

I am happy with either the Bose or Yamaha with the K3. The Yamaha works just 
fine.  You don't need noise cancelling and the Yamaha does not need a battery.  
I reserve the Bose for use with a laptop while traveling.  The Yamaha pretty 
much stays permanently attached to the K3.  The Bose works just fine in 
conjunction with the MH2 however.  I got the Yamaha originally not because I 
needed it but because it was cheap.  I have never regretted that purchase.

I get uniformly complimentary comments on voice quality and excellent results 
penetrating pileups on 100 watts with either the MH2 or the Yamaha mic.  I see 
absolutely no need to buy anything more expensive.  

Mics on the K3 are not plug and play.  They have to be set up and configured 
properly.  If anything is wrong the mic may perform badly or not at all.

As far as desk clutter is concerned, I love using a boom.  Completely hands 
free, no desk clutter, the mic goes to your comfortable sitting position and 
most importantly it looks cool and professional.  Used booms are available 
cheap at flea markets if you don't want to spend about $100 for a new Heil boom.

Gary,

Both those microphones should work well with the K3.  Couple that with the fact 
that you hear things OK in the monitor.
That suggests that there is something else wrong with your K3.  I would first 
check the filter selection for transmit using K3 Utility and make certain the 
actual 2.7 (or 2.8) kHz filter is selected for transmit.
All the rest that I can offer is that one K3 I had a hand in testing needed to 
have the Reference Oscillator re-calibrated because of a similar problem - that 
is worth a try.
If you continue to have problems, contact Elecraft support for additional 
assistance.

 Perhaps there's a problem with the mic or the settings but I bought

 warm up. A bit of overkill that's not worth exploring.

 I just looked on the Elecraft product list  see the MH2 and the Heil 
 Proset. The MH2 is surely wired properly for the K3 but I wonder about 
 the quality of sound its element generates. It looks like the Heil 
 proset would be the ideal if I worked SSB frequently but I don't. The 
 MH2 would surely be fine for the occasional use but I've never cared 
 for having the thicker coiled wire hand for hand mics extending out on 
 the desk from the radio.

 If I got something like the heil proset I couldn't use my QC15 and I 
 seriously wonder if the Heil comes close to the audio quality in this 
 Bose headset, I don't know, I'd have to compare to know. The QC15 is 
 the finest headset I've ever used for radio, thanks to the electronic 
 noise cancelling feature I can't hear the amp at all and I keep the 
 fan at full speed. As a musician the QC15 give a really pleasant 
 reproduction and are very comfortable.

 Any suggestions on something else I might look into that is less 
 pricey than this Heil set  maybe better sounding than the MH2? I 
 don't have to have it now and am not in a rush.
