Re: [Elecraft] Silent power supply for a K3s

[Bob Nielsen - N7XY]

The Astrons are quiet and pretty reliable.  I have had a RS20 since 1980 
and the only problem I had was cured by replacing the regulator chip 
about 35 years ago.

etc.

It is amazing what proper station design/construction can do for making 
silence. Open faced metal shelving and bare desktops don't cut it.

Just for grins, I put one of those Nanoxia fans in my IC-7300 and silenced it 
completely. Worth the few dollars and effort. No temperature changes noted. 
Hmmm - KPA500?

Re: [Elecraft] OT: Metric system

This was done by many stations when the price of gas first exceeded 
$1.00 per gallon the (all mechanical at the time) pumps couldn't handle 
3 digits.

Hi again,

Hopefully Eric will find it in his heart to let this thread continue.

Yes, we are. Booze and wine are now sold by the liter. Curiously beer is
generally not. In my opinion gas stations should be the next in line to
convert. I am sure modern pumps could easily be reprogrammed to display
liters instead of gallons. To the uneducated the price per liter would look
like  a bargain. Wow, less than a dollar! I don't think super markets would
encounter a huge cost converting from lbs to kilos either. Probably the road
signage would be the biggest cost problem.

As I recall from school, Thomas Jefferson proposed that the U.S. switch

Just for the record:

50 C =  122F

55 C = 131F

60 C = 140F

Re: [Elecraft] Tuners and spurious responses

[Bob Nielsen, N7XY]

DLW Associates makes a filter which has 40 dB rejection across the 
entire broadcast band.  It is available from DX Engineering.


On 12/22/18 7:20 PM, Al Lorona wrote:

  No, not a null, but a rolloff. When I quoted -40 dB I didn't mean a notch at 
one frequency, but the stopband level reached by the time you get well into the 
broadcast band. So that would be -40 dB on all AM stations below a certain 
frequency.
The K3 is a good receiver, but every receiver has its limits and certainly the 
K3 will suffer once an interfering signal gets above a certain level.
A trap or stub would work, but my point was that it would be unnecessary if 
using a link-coupled tuner. Attenuating a 50 kW station by 40 dB makes it  
sound like a 5 W station.
Al  W6LX




That said, is suppose it IS possible that a tuner/antenna combination
just happened to have a deep null right on the frequency of a nearby
broadcast station

Well, S0 noise can be frightening because it makes one think the front end
has gone out on the radio.  But then I’m always duped when the first CW
signal comes in and blasts my ears out.

Today: SFI=69 and SN=0 (yes ZERO), but NEVER let that keep you off the
air.  I had some time this afternoon and managed to work Germany and France
with 5 watts.  Had it not been for QRM, I would have had a nice rag chew
with France.  Unfortunately the QRM kept stepping on my signal (I could
hear him as well.)

Other stations heard today include OJ0DX (Market Reef) and Kuwait.  Had
the other stations been a little more patient, I’m sure I could have worked
both.  I guess they thought they weren’t making enough contacts and moved
on to other bands/modes.

Never give up!  Never say die!  (Who knows the movie quote?)

What I need is an alarm app for my iPhone that tells me that HF conditions

Re: [Elecraft] Craziest / most rewarding QSOs

The most rewarding QSO I DIDN'T have:

A few sunspot cycles ago I tuned around 10 meters from my then-QTH in

Re: [Elecraft] Data transmission on 30 meters with PX3 problem

[Bob Nielsen, N7XY]

Back in my early days as a ham (1950s), I inadvertently discovered that 
the metal housing of a D104 microphone was very effective in performing 
such a touch test.

Hi Gwen,

Don is correct. The W3EDP with a large choke Balun, as pictured, between
the Unun and KX3 is an OCF Doublet with a resonant frequency of 11 MHz.
It is rather difficult, if not impossible, to isolate a dipole end
impedance using a choke Balun. The KX3, being at the high impedance
point on 30 meters, will experience a rather high RF voltage.

A way to determine if the rig is part of the antenna is to use what I
call a "touch test." Observe SWR while transmitting, if touching the KX3
antenna BNC jack causes the SWR to change, then the KX3 is part of the
antenna. At the extreme, the touch results with a RF burn. I have
experience RF burn at 15 watts.

Re: [Elecraft] Bluetooth latency and CW reception

Thanks for that reply Phil.  Actually I also have Phonak hearing aids 
and a ComPilot II.  I will give that a try after I get my new K3S

I have only had the hearing aids for a few weeks but the improvement has

Welcome to the club.


Has anyone been able to use a bluetooth connection (such as bluetooth
headphones) successfully on CW?

My hearing aid devices (Phonax Audeo) use an around-the-neck pendant
adapter (Phonax ComPilot II) that does BT to and from my cell-phone but
couples to the hearing aid devices inductively.  It has a 3.5 mm  jack
that will feed external audio to the induction system as well.  Standard
3.5 mm M-M patch cord from the headphone lack on the radio or the
computer puts the audio sounds into my ears with no noticeable latency
problems, as tested with my K2.  They also make a BT adapter for
across-the-room TV sound use but I have never tried it because I have no
need for that.

Enjoy hearing again.

[Elecraft] Bluetooth latency and CW reception

[Bob Nielsen, N7XY]

Like many of us of a certain age, I have started wearing hearing aids 
(actually I first tried one 20 years ago but since my hearing on one ear 
was still pretty good at the time I gave up on it soon after).  Now I 
have issues in both ears and am essentially deaf in one so I got aids 
with CROS technology to feed sound from both sides to my better ear.


Because of the technology involved in this, I was unable to get 
bluetooth capability in my hearing aid and have an adapter which 
receives bluetooth and  I have been told that it sends it to the aids 
with a very low power 10.6 MHz signal.  This works quite well but 
ordinary headphones aren't very comfortable when wearing the hearing 
aids and I would prefer to not have to remove them when operating.  I 
have been thinking about getting a bluetooth transmitter to connect to 
my K3S instead of using my headphones. However, I suspect that latency 
may be an issue and there might be an unacceptable delay between the 
keying input and the sidetone received by the hearing aids.  I N7XY'm 
also concerned that RF (especially on 30 meters) might saturate the 10.6 
MHz receiver inside the hearing aid.


Has anyone been able to use a bluetooth connection (such as bluetooth 
headphones) successfully on CW?

32-bit Linux is pretty dead as OS on desktops/laptops. Sure, many embedded

Re: [Elecraft] Experience with KX2 indoors

[Bob Nielsen]

As I mentioned previously on this list, I operated WPX CW from 
northeastern France in 2004 with my 10 watt K2 (running 5  watts) and a 
W6MMA MP-1 mini-screwdriver antenna plus counterpoise from a 6th floor 
hotel room.  The antenna was sitting on a table near the window and I 
worked quite a bit of DX, including Tunisia and United Arab Emirates.  
Being the only entrant in the 20M QRP category, I naturally came in 
first place.  Prior to the contest I worked many additional stations 
including Aland Islands at 10 watts.  Of course, propagation was a bit 
better than is currently the case.


Caveat: This was the Elecraft version of that antenna (no longer 
available) which had the loading coil painted in Elecraft grey, which 
obviously added some additional mojo.


I'm planning on setting up the same antenna for use with my KX2 from my 
ground level apartment but don''t expect quite the same performance.

Other than I-5, Oregon's highways are one lane each way with few

roads fill up fast. Local news reported that one town in the eastern 
Willamette Valley had a 30 mile long bumper-to-bumper back up 
yesterday. I-5 should be moving at least.


Here in Newport on the central Oregon coast (within the band of 
"totality"), traffic is heavy and growing worse by the day. People 
are being reminded that they may NOT camp on the beaches. Besides, we 
should have record high tides caused by the sun and moon tides 
converging on eclipse day. Many beaches will be under water. Lodging 
and camps are at full capacity. In spite of visitors being warned 
they will be fined, we expect to find roadsides that have any space 
and parking lots everywhere filled with campers and trailers. During 
the eclipse we expect to find vehicles just stopping in the road to 
watch, oblivious to the fact it stops traffic for as long as they sit 
there (that already happens from time to time every summer when 
people stop in the middle of the highway, get out of their vehicles, 
and take pictures (sigh...).


The local telephone services are installing many hundreds of portable 
"towers" to augment the regular cell towers. Even so, I won't be 
surprised if Wayne is correct: Amateur Radio may be the most reliable 
communications system.


Also, hundreds of additional ambulances are on scene to handle more 
emergencies, although whether they will be able to get where they 
need to go is in doubt. Many roads have NO shoulders where people can 
pull over. A deep drainage ditch runs down each side of most rural 
roads just off the edge of the pavement.


A number of helicopter ambulances are arriving to help where 
emergency vehicles cannot reach.


National Guard personnel are being dispatched to help with traffic in 
various locations and they have better off-road vehicles for places 
where the highways are jammed.


One major concern locally is on the morning of the 21st when people 
here discover the sky is overcast (as it usually is on the coast this 
time of year- at least until noon) they will try to head east along 
US20, one lane each way through the 3,000 foot coastal mountains, to 
reach cloudless skies.


Gas prices up over a dollar ($3.25 yesterday) and are sure to 
continue to rise as long as the pumps don't run dry. Gas is delivered 
from over the coastal mountains and it's likely that no new 
deliveries are being made before the crowds dissipate.


Similarly, grocery store shelves are emptying out and may not be 
restocked before the eclipse.


Our local water company is concerned about handling the load imposed 
by having 5 or 10 times the normal number of people using it. They 
recommend storing extra water now.


Overall the emergency services point out that this is a great test of 
our readiness for the anticipated "Cascadia event" that we train for 
regularly including strong earthquakes, tsunami and no passable 
highways for several days at least.


That may be, but August 22nd will be a great relief!

Re: [Elecraft] BL2 -- Antenna Balun Usage

[Bob Nielsen]

Even Jasik, ed., "Antenna Engineering Handbook" mentions the balun.  My 
first ham antenna (1952) was a 40 meter dipole fed with 72-ohm twinlead 
and a B 1:1 air-core balun and I once worked on an airborn military 
system which used a balun.


The term "unun" has a much more dubious justification, however (my opinion).

PLEASE ignore all of Jim's pontification.

I find it curious that Terman ("Radio Engineering"), Kraus 
("Antennas"), Johnson ("Transmission Lines and Networks") all use the 
"meaningless" word "balun" in their books. Clearly, these guys should 
have consulted with Jim before doing so, because obviously they didn't 
know what they were talking about.


A transmission line transformer can be as simple as a geometric mean 
quarter-wave line between two different impedances.  No ferrites 
required.  A balun (pardon me, I'm with Kraus) can be a quarter-wave 
open stub at the feedpoint of an antenna.  Collins ("Fundamentals of 
SSB") calls this a "Bazooka-type balun", but what does Collins Radio 
know about anything?)  Or, it could be a half-wave line connecting the 
two halves of a dipole.  A stub balun can be both a balancing device 
and an impedance transformer at the same time.  And it's nothing but 
coax.  A two-wire line wound around a core might be a common-mode 
choke, but if it's long enough and different in impedance from the 
load, then it's an impedance transformer too.


In summary, just removing the term balun from one's lexicon doesn't 
simplify anything.


And I almost forgot, that N6BV article Jim mentions is titled, "Don't 
blow up your BALUN."

I am no expert when it comes to baluns


You're not the only one. :)

Some important comments. First, PLEASE strike the word "balun" from 
your vocabulary. It is a meaningless word that tells us NOTHING about 
the device or circuit element it is used to describe. I can think of 
nearly a dozen VERY different devices that are CALLED baluns. Use the 
word "balun" conceals what the device actually is and prevents 
everyone involved from understanding what it does.


A two-wire line wound around a ferrite core forms a COMMON MODE 
CHOKE. It is not a "transmission line transformer," nor is it an 
inductor, nor is it a transformer at all! The ferrite core carries 
only flux due to common mode current, and loss in the choke is I 
squared R, where I is the common mode current and R is the resistive 
impedance of the common mode choke.


Arrays of common mode chokes CAN be wired in series/parallel 
combinations to match circuits of differing impedance, but that 
device is NOT a transformer, it is an array of common mode chokes. If 
we want to know how this array of chokes work, we must analyze them 
as arrays of common mode chokes, not as a transformer.


A transformer, is, by definition, two windings that are magnetically 
coupled, and the impedance transformation ratio is the square of the 
turns ratio. If we want to know how a transformer works, we must 
analyze it as a transformer. It's as simple as that. The ferrite core 
carries ALL of the flux, and thus all of the differential power 
carried by the circuit into which it is inserted.


In general, common mode chokes do NOT affect the differential signal, 
but there CAN be differential mode loss in the transmission line that 
forms the common mode choke due to transmission line effects. For 
example, if the common mode choke is inserted in a badly mismatched 
transmission line, there can excess loss due to SWR throughout the 
line, both in the part of the line that forms the choke and in the 
rest of the line. Below UHF, virtually all loss in real transmission 
lines is due to I square R; if the combination of the antenna and the 
line places a current maxima at the choke, that segment of the line 
can burn a high fraction of the transmitter power, greatly reducing 
the transmitter power that gets to the antenna and overheating (and 
frying) that segment of the line. N6BV wrote an excellent 
applications note about this for QST several years ago, to which I 
contributed.


It IS practical to model (predict) dissipation in a common mode choke 
using NEC. A single wire is added to the model with the geometry and 
physical connections of the transmission line, and the known 
(measured) impedance of the choke is added as a Load at the point 
where it is inserted in the system. NEC is then set to model with a 
defined transmitter output power (for example, 1,500W), and currents 
are computed. NEC then provides a readout of current at every point 
on every conductor, and the current in the choke is used to compute 
dissipation in the choke.


Tutorials at k9yc.com/publish.htm show a practical method for 
measuring the common mode impedance of ferrite chokes, and for 
determining values for a parallel equivalent circuit that can provide

While the mcHF has some digital audio circuitry, I don't believe it
provides a digital voice mode.

FreeDV is a very narrow-band (1.1 kHz) digital voice mode using the
open-source Codec2, developed by VK5DGR.  One can run FreeDV without a
computer using the Rowetel SM1000 adapter
(https://www.tindie.com/products/edwin/sm1000-freedv-adpapter/). This
should work nicely with a KX2 or KX3 for portable FreeDV operation.  I
haven't tried doing that but it looks fairly straightforward.

Re: [Elecraft] K3/K3s; Digital modes, specifically DV

[Bob Nielsen]

While the mcHF has some digital audio circuitry, I don't believe it 
provides a digital voice mode.


FreeDV is a very narrow-band (1.1 kHz) digital voice mode using the 
open-source Codec2, developed by VK5DGR.  One can run FreeDV without a 
computer using the Rowetel SM1000 adapter 
(https://www.tindie.com/products/edwin/sm1000-freedv-adpapter/). This 
should work nicely with a KX2 or KX3 for portable FreeDV operation.  I 
haven't tried doing that but it looks fairly straightforward.

Greetings to all,


The K3/K3s is an excellent radio for digital modes due to the ease of
interfacing with a computer if desired.  A computer is not even needed
for some digital modes, and I have tried that successfully.

I have mentioned in the past that I had tried the free software for
digital voice on HF called 'FreeDV'.  I had worked a Canadian ham a few
times using it and he has been keeping in contact with me via email
encouraging me to get back into it.  I am starting to get up to date
again, and I found accurate reviews of it on
http://www.eham.net/reviews/detail/11016   by K2RWF and WA0TPN.  I think
you will find the reviews interesting and informative.

Notice that the reviews seem to be either at, or near, 5/5 or 0/5. I
think both of the reviews I mentioned answer why that is.  I will keep
my experience mute and let you glean aye/nay from the reviews. Whether
you approve of digital voice or not, the K3/K3s is a natural for using
it, and it's fun.  (As always with digital modes, be kind to your finals.)

included.

Larger amps will *REQUIRE* a 240VAC circuit which, unlike Europe, we in the
USA seldom have unless special wiring is installed.

Charlie, I think one of the main reasons for switching to a smaller amp was
the weight involved in the 1.5Kw rigs.  Just thought I would add back in.
The MJF AB1000 combiner looks interesting, but I would not touch one unless
I knew of many who used one successfully.  That way I could get a second
KPA500, and run 1KW which adds the 3db and I could move the separate parts
with ease.  :-)

Well, if you've never tried to work truly "weak" signals, I can assure you
that +5 dB WILL make a world of difference.
Otherwise, why would you go to the trouble of installing a ½dB noise figure
pre-amp at the antenna, just to eliminate 2dB of feed-line loss on receive?
Or, stacking a second Yagi to gain at most, +3dB?
Yes, +5dB can be very hard to come by when you're operating at the fringes
of performance.
My thoughts are, if you're gonna run an amp at all, go for legal limit.

Not knocking anyone running 200 or 500 or 700 watts, just my own opinion.

Advising Elecraft about producing a larger amplifier is quite a bit above my
pay grade so I won't go there. However, going to 1,500 watts from 500 watts
is a bit less than 5 dB -- a little less than one International Standard
S-unit.  5 dB might come a lot cheaper from an antenna change.

Before purchasing the KPA500, I ran my "1,500 watt Behemoth" at 500 W for
close to a year to see if I could tell the difference. Admittedly, I'm a
casual contester and DX'er, and I operate my ham radio for other reasons
too, but I really couldn't see much if any difference in terms of who I
could work or how long it took to snag the latest expedition.
Operating skill [or lack thereof in my case] was a much bigger factor.
The KPA500 was full QSK which its predecessor was not, which became a big
advantage.

I have since sold the KPA500 [and KAT500] and run 100W from home. My
HOA-Stealth "wire on the fence" is close enough to the house that I
occasionally make something happen [like flash touch-lamps or reset the
u-wave clock], and I figured 500 W might nuke the neighbor's dog who patrols
the other side of the fence.  I'm very surprised that the wire,
6 feet high, works as well as it does. If I quest for QRO and "real
antennae," I can always run W7RN remotely.

Re: [Elecraft] K3S Set-up for WSJT-X

As long as there is sufficient isolation in the switch there should be

I want to buy a two position coaxial switch.  I want to connect ONE 
antenna to it and switch this antenna between a KX2/KXPA100 (100 
watts) and a KX1 (about 3 watts).  The coax cable coming from this 
switch to the KX2 is a short piece of RG8X and the coax cable going 
from this switch to the KX1 is 25' of RG-174 (yes, I already computed 
the dB loss and I can live with).



Am I likely to cause any damage to to either piece of equipment?

I've assembled a great mini digital station with my KX3 and a portable

Recreated with modern technology it shouldn't be any larger than a

Has any company made a similar interface where size was a primary concern?

Re: [Elecraft] [KX3] Re: Magnetic loop antenna for the KX3

[Bob Nielsen]

Another possibility for portable operation is the SuperAntenna MP-1.  I 
don't know if the current MP-1 is any different from the original W6MMA 
version but I had good results with my Elecraft edition (which had the 
coil painted the same color as my K2). Perhaps the color made a 
difference.  I took it with me on a vacation trip to northeast France 
and worked around 20 countries on three continents on 20 meters from my 
hotel room, including A6, 3V, OH0, EW, 9A.  The MP-1 was sitting on a 
counter next to the window of the room with about a 15' counterpoise 
laying on the floor.

Reading the mail in this group always makes me realize how little I know.

In the last year since getting back on the air after at least 25 years

End Fed Quad is the easiest to operate with. I didn't even have to 
fiddle with  cutting the tuning stubs. The Alpha Antenna Loop also is 
very easy to set up and tune. I have been very successful with it on 
40 meters from a second floor bedroom. The Buddistick is the most 
finicky to set up but it also has performed well for me but I use it 
the least. In all I have had contacts in 29 countries,  worked 45 
states on 40 meters, and 34 on 20 meters. I have done this with my kX3 
using CW, SSB, PSK , RTTY  and a few on JT65, never going above 10 
watts, usually at 5 and some even at 1. I even spoke with a chap 
flying at 35k feet in a 737 on USB and what a thrill that was. Funny 
how I've never had a contact with someone using a KX3 on the other 
end. As for software I use HRD and Win4K3. Both have their strengths 
and weaknesses.


All I can say is this is a fun hobby for everyone at all levels of 
expertise. It isn't hard to make contacts so long as you are patient 
and don't have unrealistic expectations. You guys that are a lot 
smarter than guys like me are an inspiration for where I can be if I 
set my mind to it. Thank you!

If you can upgrade your mac to 16gb ram (check out https://www.macsales.com/) 
then running Windows in a VM such as Fusion or Parallels works great. For the 
MacBook Air or older MacBook users with 8 or even 4gb ram the best option is to 
set aside 20gb disc space and load Windows into a BootCamp partition (just run 
the BootCam assistant) because of its full Intel chipset. The computer is then 
a dual boot and can boot directly into Windows. Its the best way to go for I/O 
complex apps such as FreeDV or HRD. Its way cheaper then buying a separate 
windows computer if you want to stay on a single computer.

I strongly suggest resisting the temptation to make any audio connections 
directly between the radio and the mac. If your rig does not have a USB port, 
get a something opto-isolated in-between such as a Signalink USB or equivalent.

[Elecraft] Begali Adventure paddle on KX2

[Bob Nielsen]

The Adventure paddle, when mounted to the KX2 with the Begali KX3 
bracket, is tilted upward from horizontal when the KX2 tilt leg is in 
position and the levers are somewhat higher than desired.  I was 
discussing this with Lyle, KK7P, and he suggested that if the leg were 
one inch longer, the paddle would be horizontal.  This would also raise 
the display a bit, making it easier to read.

Yes.
The digikey part that I purchased is:
  
http://www.digikey.com/product-search/en?keywords=S-ND
  
I just straightened out the pins, wrapped the wires around the pins and

soldered and shrink-wrapped the wires for protection.
I used a twisted pair with a ground shield.
I ohmed out the pinouts from my KXPD3 key and hooked up my Begali
Adventure the same way.
You need to be careful though that the Begali Adventure mounting bracket
doesn't put any undue strain on the Digikey connector where it attaches to
the  KX3.
You may need to shave off a little of the plastic as the Begali mounting
bracket is slightly larger then the KXPD3.
I am S much happier now with the way the Begali connects to the KX3
and it is such a better key with a much better operating angle than the  KXPD3.
Let me know if you need any additional information or have any other
questions.
Thanks.

Re: [Elecraft] [KX3] Headphones for KX2/KX3 for Single sided deafness

As another ham who is deaf in one ear (although I was in my 50s when it

Joe,

I suggest that you are looking at the wrong parameter. Audio folks have
not done "impedance matching" for a long time now.
You should be looking at the SPL ratings for the headphone instead -
that is an indicator of the sensitivity.

The audio amplifier output is a low impedance and will feed as much
power into the connected device (speaker or headphones) as it can take.
Consider a parallel - plugging a lamp into an AC mains receptacle.
The AC Mains receptacle is a low impedance source. If you plug in a 25
watt bulb, it will produce the light of a 25 watt bulb, but if you plug
in a 100 watt bulb, it will produce more light - same low impedance
driving source.

Just guessing here ---
Is it possible that your single headphone has a mono plug on it? If so,
it is shorting out one channel of the KX2 audio. Change it to a stereo
plug with the tip and ring connected together. (caution, wires in
headphones can be difficult to solder, some are nylon fiber wrapped
loosely with copper braid for flexibility).

Alternately, just use a regular set of headphones - yes, you will not
hear one side, but the audio should be better.

hopping all the time. You could hear scientists from all over using calls
ending in -IGY, standing for international geophysical year. They traveled
to far-flung places to take readings on propagation, weather patterns,
aurora, and anything else they expected to be affected by the record levels
of solar activity. Those were the days of phone patches (no Skype), and 15
phone had a constant flow of patched conversations from scientist phoning
back to the home folks. Even in those days there was SSB activity, mostly
coming from 10 watt phasing exciters. Other popular rigs included the
Viking Ranger and the Heath DX-100. The tube of the day was the 6146. The
older hams who mentored me had home-brew rack-mounted monstrosities,
plug-in coils, something like a pair of 250TH tubes modulated by another
pair of 250THs, power transformer as big as a wastebasket.

Re: [Elecraft] Strange Interference

I'm on Bainbridge Island in the west-central part of Puget Sound and I'm 
not hearing anything (not much in the way of signals either).  Of course 
it is several hours later.

Re: [Elecraft] Linear PS Recommendations

[Bob Nielsen]

Since the KPA500 has its own linear supply, you probably don't need much 
more than 20 amp capability. I have used an Astron RS-20 for the past 35 
years but I would probably go for the RS-35 or RS-50 if I was getting 
another one.

I will have plenty of power soon...  40 Amp 220 VAC sub-panel going in with 8 x 20A 120, 
1x 15Amp 220, 1 x 20A 220 (yes, I know the sub branches total more than the sub-IN...  
total up the breakers in your main service).   The wiring is such that I can up it to 60 
Amps if/when I "need" it.

I just can't deal with this SMPS anymore... Ran one net on battery power and it

will still need a nice quiet hoss of a linear to feed the charge controller(s).

Re: [Elecraft] K3 power oddity

[Bob Nielsen]

Running at reduced power for RTTY is probably a good idea.  My TS-570 
died in the middle of a RTTY contact at 100 W. and as bad as that was, 
I'd hate to think of it happening to a K3!


Bob, N7XY

Thanks Don for the explanation of what is going on with the "ALC" meter.

I have two suggestions relative to using my K3/100.  The first is a 
suggestion I made by email some years ago, with no reply.  When 
changing from "Spkr + Phones" to "Phones" ( that is, spkr off) I need 
differing audio levels due to the different efficiencies of the 
speakers and phones.  So I crank up the gain on when using phones.  So 
far so good.  BUT; the monitor level remains constant, and changing 
that is a different process.  I'm sure that for some, having the two 
audio levels independent is a good thing - for me, it wold be nice to 
link them.  Could a menu option be constructed which would allow for 
linking monitor and receiver audio?


My second problem is that when running CW or SSB, I like to use full 
power  (100 W).  On digital modes or FM, it seems prudent to limit the 
rig to 50 W.  The power level is currently saved "per band" - cold it 
be saved "per mode" as well?  This would save a lot of "oops" time.


Or maybe these functions are already available and I just haven't 
found them!

Lee (and others)

It is normal for the power control circuits to be reset after a band 
change.  That prevents overshoot if you are driving an amplifier.
Normally the power will come up to the requested power level in a 
couple dot times on CW, or several syllables when operating voice.


If the problem is on voice or data, make sure you are driving the 
audio sufficiently.  If you are not driving the K3 audio hard enough, 
power control will be "flaky".


For Voice: With the compression set to zero, you should produce 5 to 
7 bars on the ALC meter.  After adjusting the mic gain for that 
indication, increase the compression as you choose - normally I would 
suggest compression of less than 10dB.


For RTTY, if you are using FSK D mode, the power control should be 
automatic, but if you are using AFSK A (or other soundcard data 
modes), then do check your audio drive - of course compression should 
be set to zero, but the audio drive should drive the ALC meter to 4 
bars solid with the 5th bar flashing.


Note that the K3 controls power differently than other transceivers.  
Ignore the advice on the internet to show no ALC and adjust the power 
with the audio level.
With the K3 (and K3S, KX3, KX2), the "ALC" meter is a combination 
"VU" meter and ALC meter.  The 1st 4 bars are there to help you 
adjust the audio level.  The onset of ALC is indicated by the 5th 
bar.  So 4 bars solid and 5th bar flickering is the "no ALC" point 
for the K3.
In data modes, adjust the power with the Power knob, not the audio 
level.

Re: [Elecraft] Uninterruptible Power Supply for K3S

[Bob Nielsen]

I also live on an island and we too have several outages a year (which 
can last from seconds to days).  Most are caused by branches blown down 
by wind, hitting and breaking the power lines (it is slowly getting 
better as Puget Sound Energy has proactively been trimming trees before 
they break).  I have four UPS devices in various parts of my house. The 
shack and my home computers and DVRs are connected to 1000VA TrippLite 
UPSs I bought at Costco several years ago and these also protect against 
surges.  I don't try to operate an amp when the power goes out, but have 
run 100 watt radios barefoot for several minutes. The batteries in my 
systems probably need replacing and when I do that I will try to silence 
the darn beep that they make (I can tell when there is an outage without 
hearing that noise). I will also  look into setting up a 12V system like 
you described.

Re: [Elecraft] N1MM Logger +

[Bob Nielsen]

I disagree somewhat.  Whenever I have connected new hardware to my Macs, 
the drivers were already there and I didn't need to find and install 
them as I often have needed to to on Windows.  I realize this won't 
always be the case but it is nice when things work this way.


The difficulties with Linux can vary considerably depending on the 
distribution used and it takes some degree of experience to solve these 
difficulties when they are encountered but at least you can often see 
where things are failing, something which is often hidden from Windows 
users.


I retired when Windows was at the 3.1 stage and Linux was pre-1.0, so my 
computing these days is more of a hobby than actual work, but it's a 
good way to keep the brain cells engaged.  I still haven't fully 
transitioned from the command line do a lot using the Terminal app.

Until the Linux folks make the installation of new hardware as easy

I'm VERY strongly in Ken's camp on this one. I started with computers 
in the early '80s with a measurement system running in CP/M, which I 
took the time to learn. I also took the time to learn DOS, and to do 
relatively simple programming in SBASIC and BASIC. A few years down 
the road, I transitioned to Windoze, because that's where the 
engineering applications I needed ran. Later, I tried to make OS/2 
work for me, but I spent more time getting those specialty Windoze 
apps to run in OS/2 than I did productive, billable work.


That's how I feel about the desire to make ham stuff run in *nix. I'm 
an engineer, a ham, a technical writer. I do NOT want to spend my time 
doing IT. I have paid those dues, and lost on the deal big time. OSs 
are not religious to me, they are practical for what I want to do on a 
computer.


A year or two ago, I went through the exercise of getting Linux and 
VBox to work on a couple of machines. It was a struggle, and I don't 
want to get into the reasons. I did that to try to run an ancient 
version Quattro Pro that happens to do engineering graphs better than 
anything I can find in current software -- it's what I use for all my 
published graphs. I got VBox running, but I've failed at installing a 
version of Windoze old enough to let me load QPW from floppies!


*nix may be wonderful if you're a programmer, but I'm not. :) As Ken 
has observed, there's way too much IT overhead involved.

Re: [Elecraft] KX3 firmware wish

[Bob Nielsen]

Hopefully any changes along that line will be rolled over into the KX2 
software as well.   My skills with paddles aren't quite good enough to 
be properly decoded for the digital modes (and my coordination is has 
gone downhill from my younger years).


After getting the necessary USB sound card and cables, etc., together to 
work digital modes I was going to try WSJT-X with my KX2 and found that 
it wasn't recognized the radio.  The KX3 selection didn't work, although 
it does appear to with FLRIG.  I guess I will have to wait until the KX2 
is added to hamlib.  I looked at the Programmer's Reference but didn't 
find anything that helped.

Optionally let the settings be stored pr mode.

Re: [Elecraft] KXPA100- How impactful to making contacts?

[Bob Nielsen]

Has anyone tried using a RM Italy HLA 305 or 305V with a K2, KX2, K3 or 
KX3?  The review in QST a few months ago was positive.  Over 200 watts 
out for less than $700 (not counting an antenna tuner).

Adding $100 or more to add a touchscreen ui to a radio provides very little 
value in my view, is silly. The radio cost to value ratio is very low (meaning 
the value is high). The only exception I can see would be integrating the P3 as 
an option (hopefully enhancing with a micro computer/ssd for logging, digital, 
extended macros...etc, basically what I'm doing now with a raspberry pi).

So that is if the cost is comparable to getting the P3.

Without the features of the P3 integrated; who changes settings so often that 
the included programmable macro buttons aren't enough?

Well, touch screen UI have also moved over to commercial products, the military

good enough to be used on commercial aircraft and in military applications, 
then it sure is good enough for ham radio.
Touch screen UI panels having become so prolific, that they have dropped the 
cost enormously, resolution is picture sharp and reliability is extremely good.
Touch screens have huge potential, and almost unlimited versatility. If you 
need more knobs or buttons on your rig, due to new features having been 
added……no problem with a touch screen.
Just a firmware update to add a knob, button, slider or meter onto the screen.
The problem with conventional rigs, is you run out of physical knobs and 
buttons when features are added to the radio. I see this in my KX3 - some knobs 
have three functions, and to try and remember what each knobs second or third 
function does, becomes difficult.

Food for thought :-)

No, some of the signals on the KIO2 connector are used internally and are not

Re: [Elecraft] K-1 4-bander suggestions?

[Bob Nielsen]

Fred, you forgot the step between passing the received code test and the 
written test: a sending test.  When I upgraded from Novice to General in 1953 
at that same office, one of the applicants passed on receiving but failed at 
sending.  He was so nervous that his fist was just too shaky to control the 
hand key.  

Novice testing by volunteers started around 1956 or so.

 He collected the papers, and hand-graded them one by one, saying

Re: [Elecraft] DVI connectors with an P3SVGA

[Bob Nielsen]

DVI connectors will do both analog and digital, if the connected device 
supports both.  My first generation Mac Mini had a DVI connector which I used 
with a DVI cable to a digital monitor.  It also came with a DVI-SVGA adapter 
which I later used with an analog monitor.

 Hi Joe,
 
 Save your money, it won't work. My understanding is that DVI is a digital
 format and the SVGA card is an analog format. So while you can get cables
 and and/or adapters that will fit they just won't work. I haven't received
 my SVGA card yet but in preparation I conducted an experiment with my PC
 using a DVI adapter. I connected the VGA output of the PC to the DVI input
 of the monitor using a DVI adapter on the end of the VGA cable. The monitor
 won't recognize the analog signal on the DVI input.
 
 So here's what I did. My PC has both a VGA and a DVI output. I used the VGA
 output from the PC to drive the primary monitor. I then used the DVI output
 from the PC to drive the secondary monitor. I then put a VGA cable on the
 other input to the secondary monitor and have it in position to attach to
 the P3 as soon as UPS drops off the card. I only use the secondary monitor
 to display the VE7CC cluster program and there is a front mounted button on
 the monitor to switch between the two inputs.
 
 If your PC has a VGA and DVI output you can do exactly what I did with your
 single monitor.
 
 The only difficulties incurred were trying to get the PC display program to
 properly identify monitor number 1 and monitor number 2. I fiddled with it
 for quite a while but I don't remember what I did to get it right. You
 should have no problem with only one monitor.
 
 (As an aside, you can get very inexpensive DVI adapters in all of the
 various formats on eBay by way of China or other Asian destinations).
 Usually for under $3.00 including shipping).

Re: [Elecraft] high-power tuner

[Bob Nielsen]

Bolometers work at pretty low (milliwatt) power levels and you would need to 
use an attenuator, which could add some error to the measurement.  Hewlett 
Packard made the HP434A Calorimetric Power Meter, which could measure up to 10 
watts by matching the temperature in a load with that caused by DC power (which 
can be accurately measured).  I often used one in the early 1960s (this was at 
work--they were a bit pricey for ham use).

 Ron, Rick, Erik: There are many reasons why temperature measurements are a
 poor way of evaluating a tuner. There is a method of power measure based on
 temperature rise. It's called a bolometer.  It only works well if the mass
 involved is small. Wiki bolometers if you want the details.
 
 I think there is an even more important reason not to use this approach.
 Let's consider the case where the transmitter has a very strong second
 harmonic say -10db. If the tuner is doing its job, tuning, not just
 matching, the 2nd harmonic will be tuned or filtered out. 10% of the energy
 will be lost. What becomes of that energy? In an ideal world that energy
 would be reflected into a dummy load, like when you use a circulator. Since
 most tuners don't have circulators, part of the energy will be dissipated in
 the tuner and part will be reflected back to the transmitter. That energy
 that is dissipated in the tuner is a measure of how well, not how poorly,
 the tuner is working. BTW in this case measuring SWR at the transmitter will
 also suggest the tuner is not doing its job well when it is. 
 
 Now we know good rigs don't have strong harmonics but I think I have
 illustrated why measuring heat is not a good measure of performance.

 As has been clearly demonstrated in this thread, there are multiple methods
 of measurement. The one that gets my vote for elegance is the one with two
 tuners back-to-back. With respect to the method that measures temperature
 rise, taking into account the mass of the tuner, one also needs to take into
 account the specific heat capacity of the tuner. One kilo of material x
 doesn't heat up at the same rate as one kilo of material y when the same
 heating power is applied. The tuner will of course be a mix of materials, so
 one would have to measure the rate at which the tuner heats up when heat is
 applied through a know heating source rather than TX power. If it is done
 that way, one needs to know neither the mass nor the specific heat capacity,
 since what one is measuring is essentially the mass times the specific heat
 capacity.

 I was investigating tuner losses a few years ago and ran into many of these

 A physicist buddy pointed out to me that the normal approach to measure loss
 in something like a tuner is to put it in a well-insulated chamber and
 measure the rise in temperature over time while transmitting. From there on
 can calculate the energy required to cause the temperature rise which can be
 used to calculate the number of watts of RF that never make it through the
 box.

 There seems to have been no answer as to how to accurately measure the loss
 in a tuner.  
 Here is a solution but requires two tuners or at least one calibrated one
 that could be used to measure others.
 Take first tuner and tune it into the mismatch, say 600 ohms.  Use an
 antenna analyzer.
 Then remove the load, and connect another tuner to the output of the first
 (back- to-back - antenna port on first to antenna port on second tuner.)
 Then put a 50 ohm load on the second tuner where the transceiver would be
 connected, and tune the second tuner to a match.  It will have the same
 settings as the first tuner, complete symmetry.
 Then measure the power in the 50 ohm load  to get the loss.
 
 Since both tuners are matching the same load, and the system is symmetrical
 the loss contribution by each tuner is half.  Repeat for other types of
 loads, and now you have a calibrated tuner to use with any tuner you want to
 test.

 You can get perfect up, and you can get OK up. You an argue about what
 works better and what works worse. But when the bands are open, you
 might be able to work DX with a cantenna under your desk. (I've heard
 stories.)
 
 I used an untuned dipole with a LDG tuner to work my first (and only)
 DXCC back in the last sunspot cycle.
 
 So what I'm saying is put something up FIRST and then start the arguing,
 I mean, discussion.
 
 (But then again there are all sorts of aspects to the hobby and if you're
 here to argue you can if you want.)

Re: [Elecraft] K2: KDSP2 - Should I or Shouldn't I?

[Bob Nielsen]

The nice thing about the KDSP2 is that you can tailor the settings to do 
different things when required.  I have had good luck reducing atmospheric and 
similar wideband noise, effectively lowering the noise floor (sometimes to the 
point where, in the lack of a received signal,  you can hardly tell if the 
radio is on.  I also have the KNB2, which acts on different noise types than 
the KDSP2.

 on 15M. I switched on the DSP and it shoved the funny noises into the
 noise floor which is higher, but much easier to listen to than the goofy
 motor noises.
 
 But I think someone else pointed out that you don't want to use it for
 digital modes.

 My K2 does not have the KDSP2 (or the KAF2) and the noise level drives me

 Is it worth building a KDSP2 or not?  Those of you who have one what do you

Re: [Elecraft] K3 and K2 simultaneous on serial to USB cables to computer

You will need to make a jumper cable between the K2 and your serial-to-USB 
cable.  See Figure 7 on Page 13 of the KIO2 manual for the connections.

Re: [Elecraft] Reference Oscillator Calibration

You might be able to use 10-15 feet of wire as a temporary receiving antenna.  
WWV has a pretty strong signal (depending on your location and propagation

 I just finished assembly and all went well.  I've had an excellent

 calibration stage.
 
 I don't have a frequency counter, though I suppose I could purchase
 one.  I've tried hitting the frequencies for WWV but I'm not picking
 anything up.  Of course, I don't have an antenna yet as the manual did
 not mention it as being a required piece of equipment.  I'm short on
 radio sense, I think. I have one on order,  but it has not yet
 arrived.  I was hoping to have the K3 calibrated and then begin
 dealing with the antenna setup.
 
 Is there any other way of calibrating the ref oscillator?  Can it be
 done online with the KUSB?Any suggestions would be appreciated.
 
 Thanks for your help,

Re: [Elecraft] LSB on 75 Meters

Is this some sort of new math?  As I see it, 9.003 minus 5.000 equals 4.003

 The VFO does not need to be the LO ... the IF can just as easily be

 You're correct it's a typo *BUT* there is no error in the inversion

 All you need to do is spend some time with the historical record.

 When you mix a 5 MHz signal with a 9 MHz signal, there's no need to stand on

 Instead, you go back to second grade and subtract 5 from 9 and get 4.

 Try the math again ...
 
 If you have a 5.0 - 5.5 MHz VFO and subtract a 9 MHz USB signal from
 that VFO you end up with a LSB output that tunes from 4.0 - 3.5 MHz
 in reverse.  Start at 5.0 and subtract the 9 MHz carrier frequency you
 get *minus* 4.0 MHz (carrier frequency) when the highest modulating
 frequency (3 KHz or 9.003 MHz) is used you end up with *minus* 3.987
 MHz - *lower sideband*!  Do the same with the VFO at 5.5 MHz and you
 will find LSB at *minus* 3.497 to 3.500 MHz.
 
 A mixer can produce F2 +/- F1 just as easily as it produces outputs
 at F1 +/- F2.  If you don't believe this ... spend some time reviewing
 the early SSB transmitter and receiver articles in QST from the 1950s
 or borrow a Drake 1A/2A/2B and learn why some bands tune backward.

Re: [Elecraft] US 60 Meter Band Changes Approved by FCC - CW Issues

For those rigs with fixed memory channels on 60 m, it might make sense to use a 
keyed audio oscillator in SSB mode.

 You're right, for transceivers that implement the 60 meter band in the VFO; 
 not all compatible transceivers do. My FT-817 has 5 memory channels for 60m, 
 thus not much chance for me ever using the new modes on it; I guess I'll have 
 to add the 60m module to my K2 for that.

 Mike,
 
 Not all transceivers shift the transmit frequency.
 
 The Elecraft K2 and K3 dial always indicate the carrier frequency, and 
 what is displayed does not change when changing modes.  With Elecraft, 
 the pitch of signals will change when changing between CW and SSB.
 
 OTOH, my Yaesu transceivers do shift the displayed frequency when 
 changing between SSB and CW, but they shift the receiver - the display 
 will indicate the transmitted carrier frequency.  If you were receiving 
 a signal in SSB mode and shift to CW, the pitch will stay the same.
 
 With either Elecraft or Yaesu, there is nothing complicated to figure 
 out - set the displayed frequency to the center channel frequency - but 
 with the Yaesu, one must do that AFTER setting to CW mode.  With the 
 Elecraft gear, you can set the frequency in whichever mode you choose, 
 then switch to CW.

 The point to be taken is that most HAM transceivers, when the emission 
 mode is changed from USB to CW, shift either the effective receive or 
 the transmit frequency by the desired amount of sidetone frequency. 
 They don't shift both the effective receive AND the transmit 
 frequency. For example, a transceiver tuned to 5357.0 kHz on the dial 
 in USB mode will produce a zero Hz AF output when receiving a 
 transmitted signal of 5357.0 kHz, and a 1500 Hz AF output when 
 receiving a transmitted signal of 5358.5 kHz. When the transceiver is 
 shifted to CW mode, the receiver frequency typically remains 5357.0 
 kHz, while the transmitter frequency is shifted up to typically 5357.8 
 kHz (for 800 Hz CW sidetone). But the new FCC rules require that the 
 CW transmit frequency be 5358.5 kHz, which will produce an undesirably 
 high side tone to any USB/CW mode receiver set to 5357.0 kHz. If you 
 are in a USB phone QSO on 5357.0 kHz, anyone sending a CW signal on 
 that channel must do that using 5358.5 kHz. The phone boys will hear 
 not the typically 800 Hz sidetone, but rather a high 1500 Hz sidetone!
