[Elecraft] K3XREF

[Phil Hystad via Elecraft]

Is the K3XREF, external clock interface, still offered as a product?

I searched Elecraft but could not find any references to it.

[Elecraft] Fwd: Astron RS-50M 13.8 vdc Linear Power Supply

[Phil Hystad via Elecraft]

Gang,

Not having nearly as many Elecraft rigs as I used to have, I do not need my 
Astron RS-50M power supply anymore.  Plus, maybe I am getting to old to lift 
it.  It is a linear power supply so has a real iron content more than anyone’s 
daily dosage requirement.  Shipping weight is 46 lbs.

Here’s the thing — I would like to sell it to a local guy (Puget Sound Area, 
Washington) so I don’t have to pack this up and ship it anywhere.  It is not 
the expense, it is the hassle.

It is in perfect working condition with the exception that the little neon 
lights for for a backlight on the meters no longer shine as brightly — 
truthfully, they don’t shine at all.  But, I never needed that nor did I ever 
really make use of the meters so I have not bothered to fix that.  I see that 
the newer models now
use LED lights so maybe if you buy this you can switch over to LED.

Any interest?  I can’t remember what I paid for it but I am pretty sure it was 
over $300.  So, to move this quickly, I will let it go for $50 if you pick it 
up at my QTH in Kirkland, WA.

In summary:

For Sale:  Astron RS-50M 13.8 vdc Linear Power Supply

Price:  $50 for pickup by you in Kirkland, WA 

It is in good working condition and you can test it here before you close the 
deal.  I just now tested
the output voltage (no load test) with my Fluke 187 DVM and it reads 13.8 
volts.l

Thanks,
73, phil, K7PEH

P.S.  You could buy it for $50 and then sell to someone else for more $$ and 
make a profit.

Ray,

Thanks for the reply and confirmation.  I just received my own message 
reflected back to me so I was hoping I would see another message and yours is 
just the ticket I needed.

So, it is indeed working — I guess low turn out this Memorial Day weekend.

I have not received an Elecraft reflector message for two days.  Are there

[Elecraft] K3 & KX3 with KPA500/KAT500

[Phil Hystad via Elecraft]

I currently run a full K-line (K3/P3 -> KPA500 -> KAT500) and I have a KX3/PX3 
with KXPA100 as my backup and portable radio.

When I first got my KX3 I wanted to use it with the KPA500 but at the time, as 
far as I remember, it was not possible without some fiddling of cables 
(physical switching) or operating one of the radios with less then full 
functionality on the interface.

Is this still true?

Ideally I would want to cable up the two radios to operate with full Elecraft 
intended functionality without having the need to unplug/plug cables or switch 
cables.  Today I see commercial dual RF input amplifiers that enable this sort 
of operation.  It is also possible with a number of third party linear 
amplifiers but this means dropping some of the nice features that Elecraft has 
enabled for automatic band selection, VOX, and other operations.

Operating with one of the radios fully in off position is fine with me in such 
a dual configuration.

Can this be done and if so has this been written up or documented someplace?

[Elecraft] Temperature or Warmth of KPA500 when "Off" ?

[Phil Hystad via Elecraft]

Living in the Pacific Northwest and having just gone through a big bath of heat 
I have become a temperature detective.  Anything not being used should not be 
radiating in the infrared spectrum above surroundings.  Thus, all of my radios 
are off.

Or, so I thought.  I forgot that the KPA500 was still on though off and I put 
my hand on the side of the cabinet and discovered some dastardly warmth — a 
“no-no” in this non-air-conditioned house.  So, I unplugged the KPA500 for the 
time being.

But, I was surprised.  I would have guessed that I would not be able to sense 
any warmth from the cabinet as the surrounding environment should have kept it 
cooler.  It was not hot.  Just warm to the touch.  Definitely not as warm as my 
iMac computer that I am using at the moment.

I should get my infrared temperature sensor and measure the actual radiated 
temperature and maybe I will do that some day.

But, is this normal?  I assume that there is a small current powering a micro 
processor and its related circuitry but should it be actually that warm — is 
there a cpu burning "idle loop" used and thus causing high current flow thru 
the processor.  

If it were not for the fact that breakfast is almost ready (steel cut oatmeal) 
I would plug the KPA500 back in and wait a while and then measure the 
temperature of the cabinet.  I will do that later.

Re: [Elecraft] KAT500 Tuner antenna selection stuck in #2 position

[Phil Hystad via Elecraft]

I have had a similar problem and in my case I was not looking at the right spot
for adjusting the antennas.

There are two different spots when using the KAT500 utility.  The Operate menu 
selection and then also the Configuration\Antennas selection. 

In my case, the Operate page would not let me change the antenna (nor the 
KAT500) because the configuration of antennas was not set up properly.  I have 
no idea how those got changed since they had been OK before but I reconfigured 
the antenna selection options and saved the configuration and everything worked 
correctly after that.

Re: [Elecraft] A Clarification: IC-7300 vs FTDX10

[Phil Hystad via Elecraft]

I answered that question two years ago and it cost me about $200.

I bought a 7300 because I thought it would be a descent backup to my
K-line (K3).  Two months after I bought it, I sold it for a net $200 loss.

I did the test that Don outlines in his message quoted below.  I searched
for weak CW stations on my K3 and then switched the antenna over to the
IC-7300 to see if I could pick them up.  Not a a precise experiment but I would
say about half of the weak signals I could hear enough to copy on my K3 were
not copyable on the IC-7300 and a few of them were not even making an 
appearance.  This test was all done with my 20-meter dipole near the resonant
point of the antenna so no tuners were involved for either radio.

But, that was not the kill-shot for the 7300.  The relay clicks on break-in 
keying
drove me crazy.

Re: [Elecraft] Elecraft K4 now in Rob Sherwood's RX performance table

[Phil Hystad via Elecraft]

I admit that I am a technology chaser.  My current rigs offer all the features 
I use as I am not
very much of a demanding operator.  But, I love technology and there is this 
thing
inside of me that says I need to have the latest of everything, always the 
latest iPhone,
the latest iMac, the latest iPad, and so on.  Cost is not an issue, it does not 
get in the way
of my thirst for technology.

That, and that only, would be the reason I buy the K4 of I ever do decide to do 
that.

From an operating standpoint, I don’t think I use any features that are more of 
an edge
than my rig back in my novice days (Eico 720 transmitter, HQ-170AC receiver).  
I admit
to be a ham operator that does not challenge the “best” of the operating 
envelope.

[Elecraft] K4/10 & KXPA100 ?

[Phil Hystad via Elecraft]

I currently own both the KXPA100 and the KPA500 amplifiers.  If I were to buy a 
K4/10, I am assuming that it would be fully functional (all interface features) 
with either of these amplifiers.

Question: are there any functional limitations with K4/10 operation of either 
of these amplifiers?


Also, I would like to know pros/cons on the following configuration:

   K4/10  —>  KXPA100  —>  KPA500

Thanks,
73, phil, K7PEH

rid of the KX3+ I will let the issue quietly drop into the back ground and 
revisit in another six months.

[Elecraft] Advice on K3 versus KX3

[Phil Hystad via Elecraft]

Looking for advice…

I am considering which of my two rigs to keep, the K3+P3 or the 
KX3+PX3+KXPA100.  My K3 is serial number 3799 and it has not been upgraded with 
the new hardware developed for the K3S and I have no interest in upgrading the 
K3.

Sherwood engineering ranks (with its default ordering) the KX3 above the K3 but 
as for me, those subtle differences in performance factors have never been 
meaningful to me so that does not matter.

The question is:  If I sold off the K3+P3, what would I be missing with keeping 
just the KX3?


73, phil, K7PEH

P.S. I almost put the K3 up for sale last year but covid changed my priorities.

[Elecraft] On Selling K3 Full K-Line...

[Phil Hystad via Elecraft]

I am planning to sell my full K-Line:  K3, P3, KPA500, KAT500.

Right now I don’t know if it is better to offer as a package or individually.  
Selling all to one buyer would be preferable.  But, is it easier individually?

Also, I still need to do the research to determine a sales price — I have no 
idea what the going rate is these days.

Any suggestions or comments welcome.

73, phil, K7PEH

Re: [Elecraft] With the K4 coming, is it time to replace this email list with a forum?

[Phil Hystad via Elecraft]

If there were an alternative to e-mail for the kind of dialog that takes place
on this e-mail reflector I think the style and format, along with operating 
rules,
of the Stack Exchange forums would be a great fit.

Now, I don’t think Stack Exchange would allow a vendor directed forum and
there is already a Ham Radio forum which is not that good in my opinion but
the way the software works, the organization, the division of posted questions 
with
answers and the voting to rank answers (and even questions) is very good.  Each
forum also has a chat mode for back & forth dribble that might come up now and
then.  

If you have not visited a stack exchange forum, consider some of the following
which I list merely because these are some I follow.

https://physics.stackexchange.com 

https://ham.stackexchange.com 

https://math.stackexchange.com 

And, this last link is a sort of directory of available SE topic areas:

https://stackexchange.com/sites

Re: [Elecraft] K3 on 2 meters

[Phil Hystad via Elecraft]

OK, I am curious…

Why was not this reference clock board not built into the 2-m option board in 
the first place.  Overall I can’t imagine that the net cost would be as much as 
designing and separating out an optional PCB and all that goes along with that 
as the combined cost of the 2-m option and reference clock now.

After all, it was recommended for SSB and CW use.  Now, I suppose that there 
are possibly people in this world that would buy the 2-m option only for FM 
comms but given that a nice separate 2-m FM rig would be cheaper it doesn’t 
make sense to me to add something like that to the K3/K3S.

Re: [Elecraft] KX2 list server - how to connect

[Phil Hystad via Elecraft]

I went and browsed around a bit.

I saw some messages posted in March about a KX1 that does not power up.  Then, 
in July there are messages with the title “KX3 doesn’t power off” or something 
like that.

Does this mean that a KX2 is either always On or always Off ?  And, would that 
occur in only April thru June?

Re: [Elecraft] K3 on motorboat.

[Phil Hystad via Elecraft]

The problem with this argument is the dichotomy of choice.  The contrast 
between art and science was introduced into philosophical discussion several 
hundred years ago.

Today, the discussion might better be divided into three categories:  Art, 
Engineering, Science with the recognition that many things real or imagined may 
include parts from all.

Re: [Elecraft] [Elecraft-KX] Made the decision to buy an Elecraft... now I can't decide which one :/

[Phil Hystad via Elecraft]

>  I doubt you’ll find a used KX2-not many letting go of these! 

I did that — I mean I let my KX2 go.  Some stupid idea got into my head that I 
wanted to get the Icom 7300 after they first came out.  So I sold my KX2 ) to 
buy an Icom 7300.  I also have a K3 & KX3 so I figured selling the KX2 would 
not hurt.  Big mistake.

I had the Icom for about a month and then decided to sell — I am mostly CW and 
as a CW rig it was not that great (mechanical QSK relay made too much noise for 
one thing).

After selling the Icom 7300, I bought another new KX2 Kit and enjoyed putting 
one together again.  I am guessing this entire mistake cost me about $250 to 
$300.

The KX2 is definitely a keeper and it is my main goto portable QRP rig.

 Hello all and thanks allowing me to join,
 
 I am new to this group.  While I have a lot of fun with QRP it has always 
 been here at the home QTH and nothing portable.  Well I got invited to a 
 SOTA activation a few weeks ago and I am totally hooked on the idea of 
 working portable so now I am trying to put together a kit which includes a 
 better transceiver.  I currently have 2 QCX 5w transceivers and have been 
 watching the news on the Icom 705 when I saw a comparison on the KX2/3 and 
 started looking toward the Elecraft.  I am very impressed with the 
 features and reviews and I have decided I would prefer to support a US 
 manufacturer.  I am also happy to see one of the owners here participating 
 in the forum, which I could not expect from one of the "other three" 
 manufacturers.
 
 So with most of my operating to be done portable, but not being someone 
 who is overly concerned about weight, I am leaning toward the KX3.  Here 
 are a few questions:
 
 1) I see there are optional filters for the KX3 - is there any option for 
 filters on the KX2?  How does it affect usability when in a high RF noise 
 environment? (for example having the KX2 with no filter)
 
 2) is there any problem with running an external battery?  I have a 
 Bioenno 12v 12Ah pack that works great with my current setup.
 
 3) How useful is the 2M option on the KX3 in making summit contacts during 
 SOTA?  Is that the main purpose for this unit or is it to have an 
 "all-in-one" for the "shack-on-the-belt" VHF types?  I don't operate much 
 VHF but I think it would be handy to have a 2M yagi on the KX3 during SOTA 
 in case the HF conditions are not favorable.
 
 4) I have done well buying used radios in the past and I see some KX3s 
 listed and selling quickly lately.  Is there a service available where you 
 can send a used radio in for a "tune-up" or just to bring it up to current 
 spec?  Is that even necessary?
 
 Thanks in advance for any help with this.  I already have a fully decked 
 out KX2 waiting in the online shopping cart but I'm hesitant to push the 
 button :D  Also I guess they are backordered so maybe I should just watch 
 the list for a used one?

Re: [Elecraft] Quiet Ductless HVAC System

[Phil Hystad via Elecraft]

I didn’t know that an HVAC system would be an RFI generator.  What part of HVAC 
is the cause of this and is this a recent problem in manufacturing units?

Note — I have never lived in a home with AC — never had a need here in the 
northwest (Seattle area).  I probably should add that when we go to our condo 
on Kauai the first thing my wife does is to turn off the AC unit.

[Elecraft] 2-Port Network Model for BL-2 Balun (both 4:1 and 1:1) ?

[Phil Hystad via Elecraft]

Does anyone have, or has done the measurements to create, a 2-port network 
model of the BL-2 Balun?

I would prefer parameters for both 4:1 and 1:1 if they exist.  I presume these 
might be h-parameter models due to transformer within the balun but I prefer 
parameters that include any Complex representation that might include phase 
shift or transformation of complex impedance.

Thanks,
phil, K7PEH

Re: [Elecraft] Electrolytic Capacitor failure

[Phil Hystad via Elecraft]

Contributing to the Astron fan mail…

My main shack PS is Astron RS-50M with two RS-35M in backup.  I originally had 
just the two RS-35M supplies but just had to move on up.

Never a problem with any of them although the RS-35M supplies are not actively 
being used at this time.

Re: [Elecraft] RFI issues

[Phil Hystad via Elecraft]

I once had a noise issue and I used my KX3 roving about the neighborhood to 
find it.  Actually, I found a number of loud noise sources doing that as I 
moved around.  It seems that if the noise level is fairly constant as you move 
around the area but will within the same general distance from the TV/FM 
station antennas you could isolate the source as those antennas or something 
else.

Re: [Elecraft] Found: P3

[Phil Hystad via Elecraft]

The videos are excellent.  Ben Eater is one of the better teachers of digital 
electronics (especially to a philistine such as myself) on Youtube.  I built 
his 8-bit computer project almost two years ago and I am in the process of 
building the 6502 computer project (yes, my own Apple-1).

Even though you may not plan on building your own VGA (which Ben refers to as 
the world’s worst VGA) you should watch the videos to understand how Ben 
teaches an how VGA signals work.

Re: [Elecraft] Reaching Across the Chronological Divide

[Phil Hystad via Elecraft]

From what I have seen, it is not just Internet and Cellular that has stolen 
some thunder from ham radio as an interesting hobby to pursue.  It is also 
computer gaming.  Both of my grandsons are into computer games (both in high 
school now) and both are involved in programming computers (some motivation 
from me as being a programmer for 50+ years) and they both want to pursue 
computer programming of games.  I hope that changes but this has seriously 
diminished any interest in ham radio and they both have grown up known about my 
hobby, electronics, and such.

Computer Internet gaming offers some of the same features of ham radio of 
meeting people all over the world that you did not know before hand.  Gaming is 
one of the Internet based activities that creates International friendships and 
cross culture exchanges.  Surprising, who would have thought.

I admit that if I were a kid growing up with today’s technology that I probably 
would not be interested in ham radio.

Re: [Elecraft] THE FUTURE OF OUR HOBBY

[Phil Hystad via Elecraft]

Back in 1960 I bought my transmitter, an Eico 720 Kit for $79.95.  My receiver 
at that time was a Knight-Kit R100.

The US inflation calculator says that $79.95 in 1960 is equal to about $695 
today.  This was a transmitter only and the only mode was CW and it was crystal 
controlled (no VFO).  If you add in an almost equal amount for a receiver than 
today’s KX2 or even for that matter, a KX3 is a real bargain.  That Eico 720 
transmitter in 1960 was a nice rig but it was low end of the transmitter 
totem-pole.

A few years after that I upgraded my receiver to a Hammarlund HQ-170AC which 
was considered one of the great receivers for its day.  However, it is no where 
close to be as good as the receiver on a KX3.  That HQ-170AC was ~$329 (in 
1965) and at today’s price would be equal to a ~$2700 purchase!

Rigs today, even the best ones, are cheap in comparison.

[Elecraft] FS: Astron RS-50M Linear Power Supply

[Phil Hystad via Elecraft]

I am selling my Astron RS-50M Linear Power Supply but prefer to sell locally 
(Greater Seattle Area) rather than box up and ship it so prefer some kind of 
local pickup (or, delivery if not too far out of my way).

It is in perfect condition except for the meter back lights are burned out.  I 
have owned a number of these Astrons and for some reason this always happens.  
My other Astron supply does not have lights in the meters either however I 
never do look at those meters so for me it was no big deal — lights aren’t 
needed anyway to read the meter.   No dents or scratches on the cabinet that I 
know of — in fact, I don’t think it has ever been moved once I put it in place 
about 8 years ago.

I also built a nice wooden table that the power supply sits upon.  It is 
designed to allow airflow underneath from underneath.  The table is sized to 
provide a height of the power supply underneath my table I use for operating.  
This table is offered as a free gift to the buyer if they want it.

This power supply retails for something above $300 depending on where you buy 
it.  I am offering it at $150.  No dents or scratches on the panel that I know 
of.

If interested, let me know by e-mail.

Re: [Elecraft] AX1 Loaded Whip Antenna - Elevation and Counterpoise?

[Phil Hystad via Elecraft]

Some points…

“…dragging along a remote tuner”

Surely you are kidding or you get the award for hyperbole of the day.  The T1 
fits in my shirt pocket!  It is zero effort to bring — no “dragging” required.

And, I operate with 50 feet of coax because carrying multiple different lengths 
of coax on various trips where I operate portable does get into dragging.  
There have been some situations where 50 feet has not been enough such as in 
one national park where the convenient picnic table was quite a distance from 
the nearest convenient tree.

Re: [Elecraft] AX1 Loaded Whip Antenna - Elevation and Counterpoise?

[Phil Hystad via Elecraft]

Sounds like an idea worth trying — I have always wondered about the coax loss 
between my KX3/KX2 and my portable antenna no matter which one it is (i.e. 
AX-1, Wire and counterpoise wires, Buddipole, etc.).

But, really glad I did not sell the T1 on several occasions of thinking about 
selling it.  I have not used my T1 since I sold my KX1 almost three years ago.

[Elecraft] AX-1 Tripod Adapter

[Phil Hystad via Elecraft]

I just ordered the AX-1 antenna Tripod Adapter but I am wondering if it fits 
the camera tripod that we have.   I need about two inches of clearance (i.e. 
radius from center of attachment screw) to clear the platform designed for the 
camera.  I am not sure that the AX-1 tripod adapter has that amount of distance 
between the BNC connector and the mounting screw.

Has anyone used this tripod adapter on a camera mount tripod?Or, do I need 
to buy another tripod and if so, any suggestions?

[Elecraft] FREE: Traffie Hexbeam Antenna (Seattle area)

[Phil Hystad via Elecraft]

For anyone in the general Puget Sound area (aka Seattle area) who is interested 
in owning a 15 year old Traffie five-band Hexbeam antenna please contact me 
offline.

I have decided to retire the hexbeam antenna.  Lately I have been primarily 
portable ops using various portable op style antennas.  I have an 80-m dipole 
that I can use on 80 thru 17 and the important part of the 15 meter band (low 
end for CW) which I can use if I need the big gun antenna :-)

So, the antenna is still on my roof and in the next few days I plan to take it 
down and take it apart.  Very difficult to move all set up as it has an fairly 
large span.  But, it is not rocket science to put together.

If you are within driving distance (pickup truck probably needed, poles are 
long) of Kirkland, WA and you want a free antenna that originally cost a little 
over $1000 then let me know.  If you find you don’t need it, maybe you could 
sell it — I am too lazy to sell it.

Please contact offline.

Re: [Elecraft] portable antennas and rigs going through airport security

My KX3 takes NiMH batteries and as far as I know, airlines do not care about 
them.  The main concern would be Lithium but even my laptop has Li batteries 
and that is always accepted.

Re: [Elecraft] Hara Arena Hit by Tornado

[Phil Hystad via Elecraft]

The “Dayton” Hamvention should be moved to the Seattle area — no air 
conditioning required.  Hold it in Key Arena (or, whatever it will be called by 
then per whoever owns naming rights).  Key Arena is part of Seattle Center 
where Space Needle is located as well as the almost 60 year old monorail and 
the bizarre architecture of Paul Allen’s  MoPoP (Museum of Popular Culture).

73, phil

P.S.  If it were in Seattle, I would attend.

Re: [Elecraft] Mobile high power

[Phil Hystad via Elecraft]

I ran mobile CW with my Begali Paddle sitting on the middle console of my 2004 
Chevy HD2500 4x4 pickup.  I had a Hi-Q antenna on the rear top mounted on the 
side panel making use of one of the stake holes to feed coax.  Operated like 
that for about 10 years.  100 watts from an Icom 706 MkIIG.

No real problems with the truck although while operating on the 40-m band key 
down would light up half the warning display lights on the dash.  This mostly 
only happened on the 40-m band though a few times I had seen it on 20-m too.

My 2018 Toyota RAV4/Hybrid has a warranty statement saying “Do not operate 
mobile based radio transmission equipment” and that this could (not would but 
could) violate the warranty.  However, I got rid of the pickup truck mainly as 
I lost interest of mobile operating in favor of portable operating (not in the 
vehicle) and in my opinion, big trucks were made for mobile ops (all that 
steel).  My longest CW contact, half way around the world, was via mobile on 
that pickup truck on I-5 while traveling thru the state of Oregon.

Re: [Elecraft] Technical question on keying of an SDR radio

[Phil Hystad via Elecraft]

Wayne,

Thanks for the explanation.  I should have realized that it might have been 
documented.

My question was prompted by the appearance of a question posted to the "ham 
radio" formum of Stack Exhange on-line.  The OP (original post) of the question 
mentioned looking at a 1976 ARRL Handbook and seeing a circuit for the keying 
and wanted an explanation of how that circuit worked.  The answers (at the time 
I read the post) were somewhat simplistic and directed to the circuit that was 
shown in the question which of course was technology going back to the 1940s or 
before.  

Thus, I was curious of the improvements possible with DSP.

Thanks,
phil, K7PEH

[Elecraft] Technical question on keying of an SDR radio

[Phil Hystad via Elecraft]

If you look at various old circuit diagrams of ancient radios made from 
electronic circuits you find that the telegraph keying for the radio involves 
switching on and off the driving oscillator frequency or something similar.

However, with an SDR, you have other options and I have no idea how it is 
typically done.  For example, a digital signal can be produced that represents 
the Morse coding and this signal need merely be converted to analog and 
amplified.  Or, is there still an analog circuit being switched on and off for 
Morse code (telegraphy) keying with a modern SDR.

Can someone describe how this is done in a radio like the KX2.  And, is it done 
differently in the different Elecraft radios — I presume that the K2 would have 
the more traditional sort of circuit but that is really just a wild guess on my 
part.

73, phil, K7PEH

Re: [Elecraft] Macintosh version of Elecraft KX3 Utility

[Phil Hystad via Elecraft]

The warning message does not merely appear just once with the first launch of 
the software but on subsequent lauches as well (after shutdown of the app).  
However, I have noticed that if a subsequent launch is within a small period of 
time after an earlier launch where the message was shown, then the message does 
not appear again.  However, after a longer period of time, the message on 
launch will appear again.

Now, definitions for "small period of time" and "longer period of time" would 
be your own assessment because I have found that it is different intervals 
depending what I guess to be arbitrary (or, unknown to me).

Re: [Elecraft] K4?

[Phil Hystad via Elecraft]

I believe many future electronic devices will not have a touch screen.  They 
will have a voice interface.  In fact, a number of devices in my home right now 
are voice operated and it seems to work just fine and this capability is 
improving rapidly in the industry.

For example, my 2018 Toyota RAV4/Hybrid has a touch screen system.  I also have 
my iPhone coupled to the RAV4 so I make calls hands free merely by saying 
something like "Siri, call home".  I also play music I have on my iPhone.  
Instead of using the touch-screen music browsing system, I merely say "Siri, 
play Beatles One" or whatever.  I have actually named my music playlists with 
names easy to use Siri for this interface.

And, instead of doing simple time-zone arithmetic, I have the habit of saying 
"Alexa, what is GMT time for now".  Alexa answers clearly with date and time.

Re: [Elecraft] K4?

[Phil Hystad via Elecraft]

On the idea of a K4...

I have not bought a K3S.  I have not upgraded my K3 with features included in 
the K3S.  And, I find myself using my KX3 and KX2 more than my K3.

The K3 is a keeper though, no reason to sell.  But, I also have no reason to 
buy any other rigs.

I am sure a K4, if ever produced would be a great radio but more likely my 
grandchildren would make more use of it then I would.  One grandson is studying 
for his Technician License so far (age 12).

Re: [Elecraft] KPA1500 vs SPE Amps

[Phil Hystad via Elecraft]

Actually, Elecraft should do that as an experiment.  They could either make or 
specify appropriate combiners/splitters to use on front and back and solve 
other problems that might crop up.  Surely they have lots of KPA500s sitting 
around.  Lots and lots. :-)

73, phil, K7PEH

P.S.  My off-hand comment can be blamed on the fact that I am sitting here 
snowed in until maybe March with nothing else to do.  I live in Kirkland 
Washington and there is 16 inches of snow on the ground (all time record) -- we 
normally have rain with merely wet streets so this is a new thing.

[Elecraft] K3 S-meter reading and coax input or antenna voltage ?

[Phil Hystad via Elecraft]

If I had an S-meter reading, S9 for example, on my K3, what could I infer about 
the voltage level of that signal at the Coax input to my K3?

A table I found on the Internet for singals below 30 MHz says that an S-9 meter 
reading is a signal of 50-microvolts but where in the system is that 
registering 50 microvolts.  At the input the K3 or some other circuit within 
the K3?

Thanks -- just mostly curious about this and the connection between S-meter 
reading and actual signals input to the receiver.

Those options I listed, USPS, UPS Ground, and UPS Next Day Air were all that

I have bought small parts from Elecraft before, like back when  a hardware fix

ridiculously small and should not demand a shipping cost twice the cost of the

Re: [Elecraft] Elecraft Web Storefront Problem

Don,

USPS Priority Mail is:  $16.98   (this is what is selected)

UPS Ground is:  $19.03

UPS Next Day Air is:  $73.68

I just shipped a few boxes by UPS ground and all of the boxes were bigger and 
heavier than the KX2 Ground Mini Banana Plug and those three shipments were all 
cheaper than the UPS Ground noted above.  Plus two of those UPS shipments to 
Phoenix AZ from my QTH in Kirkland, WA were cheaper than the USPS Priority Mail.

Yes, I will call tomorrow and order via phone.

So far, I am not liking the new web site.

[Elecraft] Elecraft Web Storefront Problem

[Phil Hystad via Elecraft]

It is a problem with me or do others have trouble ordering online.  Actually, 
the problem is that the postage due calculation has got to be way off.

I wanted to get the little MINI KX2 Ground Banana Plug for $7.95 and the 
postage due was $16 and change.  Didn’t seem to matter how I selected things.  
This banana plug is small enough to be shipped in a regular 45 cent postage 
stamp.  I can see extra charges for preparing that mailing but hopefully not 
more than double the price of the item I am hoping to buy.

Does anyone else have this problem?

Re: [Elecraft] Elecraft KX3 Utility error on Mac OS X High Sierra

[Phil Hystad via Elecraft]

One thing to try is to download a fresh new FTDi driver and install that.

Re: [Elecraft] Why Black

[Phil Hystad via Elecraft]

I started the trend of black :-).

Back in the early 1960s, my home-brew dual-811 linear and its power supply both 
had black wrinkle 19 inch rack cabinet front panels.  Also, I built a SSB 
exciter that also had black wrinkle 19 inch rack front panel.  I even had the 
black wrinkle rack cabinet to go with these rigs.  A big black tower of 
equipment -- well 48 inches high.

Re: [Elecraft] DX World Transceiver survey

[Phil Hystad via Elecraft]

Surveys that collect information from the users of the service or product don’t 
usually publish volume or number of units sold.  They will publish information 
on numbers of persons surveyed or break down numbers per product type.

It is a totally different type of “survey” that reports on product comparisons 
including units sold and so forth.  That kind of survey is what you would 
expect from a Consumer Reports product review, not a survey of users.

Usually, a survey that requests you to pick from a selection of products is no 
different then a high school popularity contest.  And, most surveys are like 
this.  Including those political polling surveys.

But, there are serious surveys too.  I once did a survey for Consumer Reports 
on a new car purchase.  It took me 30 minutes to finish.  I think it had on the 
order of 100+ questions.  It was years ago and not even an on-line survey.  I 
can’t remember how many pages were involved but it was enough to result in an 
extra heavy return envelope though postage was prepared.  I had to mark a whole 
lot of little check boxes and so on with a black pen.

Re: [Elecraft] Operating KX3/KXPA100 on LiPO3 batteries??

[Phil Hystad via Elecraft]

Bruce,

I read on-line Amazon question on the battery asking about simultaneously 
drawing from the battery while charger plugged in.  The answer, from Bioenno 
themselves, was that this should not be done.  The charger and using the 
battery should not be done simultaneously.

Is your battery different in that you can charge it while using it?

[Elecraft] Operating KX3/KXPA100 on LiPO3 batteries??

[Phil Hystad via Elecraft]

Has anyone operated a KX3 with the 100-watt KXPA100 using LiPO3 (or other Li 
chemistry) batteries.  If so, what was the battery brand, number of cells or AH 
rating, and performance and at what power levels.  I don't expect any research 
quality answers, just the experience and capability of the batteries.

Thanks,

Re: [Elecraft] Vanity Calls

Ditto for Washington State — copy of FCC license required to get call sign

Re: [Elecraft] K-Line Climate Control

[Phil Hystad via Elecraft]

Surprised to see the term "Climate Control".  Sorry to be fussy and pendantic 
but this is not a climate control question.  Climate is the long term, local & 
world-wide, changing of weather parameters/variables.  More correctly this 
would be environmental control of the operation of your rig considering weather 
changes and even extremes of weather.

(pre-punched) and then keep them in a binder.  This way, I can add notes here 
and there in the right spot merely by inserting another 3-hole punched paper or 
punching printed e-mails or something myself.

I think this is the absolute best way to manage the information you will 
collect over the years on different things like suggested settings for 
this-and-that and so on.

Re: [Elecraft] Adapter for use between iPhone headset and a KX2/KX3

[Phil Hystad via Elecraft]

Wayne,

I have yet to use voice (SSB) on my KX3 or KX2 having been so far CW only.  Are 
there any other
audio settings you have set other than those you mention below.  Do you 
recommend speech
compression set to max or was that just a test of audio quality check.  I will 
experiment but it
would be nice to know what starting points and boundaries make sense.

I still have all my iPhone headsets from my original iPhone 1 through my 
current 6s.  Actually,
still have all those iPhones too.  I may test each one to see how they work — 
now, I need to
find them all though.  Just ordered the Y-adapter cable from Amazon.
