And you are sure the antenna and coax connections are O.K.?

Forgot one thing about the 30m VSWR situation:

While the ATU was trying to tune the antenna, it started at something 
like 25-1.  It got down to about 6-1 after quite a bit of noise, but all 
during this time my external wattmeter indicated zero power output.  On 
all the other bands, it shows a low power while tuning.  It also 
produced no power when I keyed it after tuning.

Re: [Elecraft] K3 Band changing...

[David Yarnes]

Alan and All,

I had nearly the same setup back in 1961-2 while stationed in Berlin, 
Germany.  Built the Apache, which worked great, then added the SB-10 shortly 
thereafter.  That was my first SSB venture, and you are right--the reports 
were good.  Problem was though, the Apache was not the most stable 
transmitter ever designed!  I had an annoying drift problem, which really 
gets accentuated on SSB.  But Heathkit readily attributed it to a design 
flaw on their part, and sent me different capacitors to use (temp. 
compensating).  Got the Apache settled down sufficiently (but not 100%), and 
life was good!  Kind of a brick though, compared to my 8 pound K3!

Many (many, many) years ago my station consisted of a Heathkit Apache
TX1 transmitter, Mohawk RX-1 receiver, and SB-10 SSB adapter.  I figured
that I had to switch or adjust a minimum of ---12--- controls to change
bands.  If I needed to change between LSB and USB, add two more for a
total of 14.  And that does not include switching antennas and changing
the dial frequency if required (on both transmitter and receiver).

That also does not include my 6 and 2 meter transverters.

In those days I thought twice before deciding to change bands.  :=)

On the other hand, the SB-10 phasing-type SSB exciter had absolutely
WONDERFUL-sounding audio.  I got unsolicited compliments on nearly every
QSO.

P.S. The list as I recall it:

TX-1:  Bandswitch
  Tune/operate switch
  Driver tuning
  Driver gain
  Plate tuning
  Plate loading
RX-1:  Bandswitch
  Antenna trimmer
SB-10: Bandswitch
  Carrier null #1
  Carrier null #2
  Tuning

Re: [Elecraft] K3 - ESSB Availability

[Roar Dehli]

Hi Joe.

Yes, I am also awaiting this firmware update. I have not yet got my K3, but
my hopes are that it will be ready soon. Right now I am also using the
IC-756pro3, microphone are the TSM MT-57 dynamic, and I use the W2IHY
equalizer into the rear ACC connector. I have also ordered a better
microphone, the AV Leader STM-11 :
http://www.avleader.com.tw/product_Studio%20Microphones.htm
This one has a very flat frequency response and needs an equalizer to sound
good.
This one also needs +48V phantom power, I have the small LEEM PHW-22 phantom
power supply. 
This one is cheap, and it has selectable +48V or +12V.

This is what amateur radio is all about for some of us, not just getting a
message thrue but making it sound as good as possible.

Best regards
LA4AMA

Great!

Are there any photos available, showing the 1- and 2 pocket design?  Or

Buy another radio that does everything you want.

Of course, it hasn't been built yet.

Here's an idea, start your own company and build "the perfect radio",
but be ready for the incessant whining (like 5 year olds) which will
issue forth from your customers because you didn't do it "their way".
The fact that it's the best performing radio on the market doesn't
matter a damn, "It won't let me do X" or "it won't let me do Y"
is all you'll hear from the ingrates.

What's the matter, just because you'd have to spend 3-4X the money to
get your dedicated band changing keypad and anywhere near the
performance shouldn't be a problem, should it?

R. Kevin, what part of that don't you understand, to justify the tone

Looking forward to your reply, and hopefully, apology.

Re: [Elecraft] K3 Band changing...Devils Advocate...

[Don Wilhelm]

Don,

Do you really want band *stacking* memories?  A stacking memory is 
first-in, last out, so you have to drill down through the stack to get 
the one you want.  That seems likea much worse situation than the normal 
band up/down switch which is a double ended stack.


If you are referring to something different, then please do not call it 
a stack - the definition of a memory stack has been quite clear since 
the first days of microprocessors.

Don Rasmussen wrote:

I brought up the band changing issue early on with the
guys, not because I just had to have it, but because
it seemed that every transceiver these days that's big

The thing that I find disconcerting is that even
though many of the buttons on the K3 are fully
occupied with multiple TAP and HOLD functions, there
are (5) that I will never ever use in their TAP -or-
HOLD capacity - those being M1, M2, M3, M4, and REC. 


These could clearly be drafted into service as band
stacking registers (on first press), yet they just
stay there hogging up space on my front panel. 


I proposed a CONFIG option that would allow the
MESSAGE keys to be used either as DVK on first press
as originally fitted, but also could be used as
bandstack keys if the user preferred that as a first
press function over the DVK. 


A minimum of 5 band stack keys are waiting there for
use, 10 if you include HOLD.

Re: [Elecraft] K3 Band changing...Devils Advocate...

[Don Wilhelm]

Dave,

I believe what is really wanted is "random access" band buttons - in 
other words a single button press for each band.  For the life of me, I 
cannot figure out how this ever has been construed in ham circles to use 
the term "band stacking memories" - perhaps someone can tell me how 
'random access'  equates to a 'stack'.


Despite the fact that several proposals have been brought forward for 
how to use the quick memory keypad (as well as the other memories) for 
this purpose (and it is also suggested in the K3 manual), the complaints 
continue because Elecraft has not chosen to make that function a 
permanent (and unchangable) feature.  I just can't understand why the 
complaints, since that 'feature' is already present if one wants to set 
it up that way.

RE: [Elecraft] K3 Band changing...Devils Advocate...

[Dave Van Wallaghen]

Ok, lets see if I get it - users want to randomly assign bands to a set of
buttons in an order of their choosing, that makes sense to the operation
they are performing, then memorize the meaning of the buttons, and call up a
particular (and memorized) band with a single button. 

And this would be more convenient than cycling through the band select
buttons, presumably because you are forced to cycle through bands you may
not need to at this point in your operation.

Am I getting this right? I apologize for the bandwidth - I'm just trying to
get educated.

It seems to me some are sitting around trying to figure out some little 
whistle they would like to add to the K3.  Its even going to become an alarm 
clock, a broadcast station, and a coffee maker.


I am glad the folks at Elecraft have a meeting of the minds before precious 
resources are spent on gagetry.


To me, resources - particularly intellectual time - should be spent on 
features that mean the K3 will dig out weaker signals, have a better noise 
blanker, work additional digital modes, be a better contest rig, interface 
with popular contest or station control software, have a tuning display that 
is useful rather than pretty, be better behaved as a driver for an 
amplifier, better DSP algorithms, etc.


I think time spend implementing some of the things I have seen mentioned 
would be a real waste, and just add to the configuration issues. IMHO this 
is a list of parameters  that is already becoming so large that users are 
never getting around to understanding them all.

RE: [Elecraft] K3 Band changing...Devils Advocate...

[John W2XS]

I haven't used the K3 receiver enough to really comment, but I like the way
the TS-930 works (with the PIEXX board installed).  There are 99 memories
available which are accessed via the RIT knob (similar to the K3 and the VFO
B knob).  In addition, there are 9 individual band buttons on the front
panel that are assignable to any frequency in that band. So, for example, I
can be listening to WBCQ on 7415 and then press the "80" button to move to
3530 (the frequency that I have programmed for 80 meters). The
direct-frequency-entry capability of the K3 is roughly the same thing with a
few more button pushes. The 930 also has "up" and "down" buttons that allow
scrolling through the spectrum in 500kHz steps.

Re: [Elecraft] K3 Band changing...Devils Advocate...

[W7TEA]

My K3 should be arriving in a 2-3 weeks so I'll
obviously pass on making suggestions until I can play with it awhile.  
My Omni VII's band stacking registers are not FIFO
but rather like having four sets of VFO's for each band at
the push of one button.  

So VFO A could be at 14.001 and VFO B operating 
split at 14.003 on register A.  Registers B, C, and D
can have their own unique settings.  Rotating back to 
Register A brings back the last frequency you were at
in this register-or 14.001/14.003.  You move thru the
registers by punching the band buttons. In addition,
there are 100 memories each able to save both VFO's
and split operation.  They take two button pushes to 
either choose or save a frequency and to transfer it 
from memory to VFO. 

Seems pretty intuitive to me and very easy to use.

[Elecraft] K3 Band Stacking

[Phil & Debbie Salas]

Band Stacking:  I can tell you how it worked on the Yaesu MKV.  There were 
two "band stacking" registers per band.  When I'd push the band keypad 
button for a particular band, I'd go back to the frequency and mode I was 
last using on that band.  If I pressed that same band button again, I'd go 
to a second previously used frequency and mode in that same band.  If I 
pressed the band button again, I'd go back to the first frequency mode, etc.


So I set up one "push" for the CW end of the band, and the second "push" for 
the SSB end of the band.  The nice thing was that I'd go back to the 
previous frequency, not to a memory frequency, when I'd push the buttons. 
So I might be checking an SSB conversation occasionally, but spending most 
of my time on CW.  So just pushing the band button (a single push) would 
toggle me back and forth between the two frequencies.

Re: [Elecraft] K3 Band changing...Devils Advocate...

[drewko1]

I don't have a K3 yet but I'm happy with the Band+ and Band- buttons
on my K2. I pretty much know how many pushes I'll need to get from one
band to another, usually only one or two away. 

Anyhow, the display changes instantly with each button push before the
relays get a chance to switch, so you can quickly step through
multiple bands, watching the display without tripping the relays,
until your target band is reached. For the ten or so ham bands we have
this seems like a reasonable way of getting around. 

I don't know that I'd want ten or twelve extra buttons for this. That
just doesn't seem any more convenient to me. In fact, it is less
convenient. (But then I am a bug and straight key op so pushing a
switch many hundreds of times in sequence is not a big deal to me,
haha!) 

I never have to look at the Band+/Band- buttons; I know where they are
by touch and can just focus on the display. I see that the K3 also has
them in the same location: top left corner. That is ideal as far as
I'm concerned.

Now, getting around the non-ham bands is a different story. I'm not
too crazy about direct frequency entry. Would prefer to just spin a
knob to increment or decrement the frequency in 1-Mhz steps, maybe
five 1-MHz steps per each full turn of the knob.

I understand there is some problem with going between ham bands and
non ham frequencies. I expect this will get straightened out at some
point.

I'm starting to think that if, historically, all rigs had come with 
Band+ and Band- buttons, plus dedicated GoToBandXY buttons, we'd be 
seeing posts asking for a knob connected by a shaft to a multi-gang 
rotary switch, hooked to a big air-wound coil with multiple taps.


I'm confident the Elecraft guys are prioritizing their efforts, and 
putting "Fifty ways to change bands" at the nether end of the list.

[Elecraft] K3 Band changing...Devils Advocate...

[Don Rasmussen]

Hey Don (FPR type),

I've been a programmer since 1980 - quite familiar
with the stack. But you're right, to me a single
button band set to a tunable memory would be the major
advantage. 

Make it a 2X "stack" to access two tunable memories
would be icing on the cake. I'd use high end of the
band with one press, low end with the next press. It
does matter that the two presses are made to the same
button, seems easier than finding and pressing two
separate keys. 

IMO 3X stacking becomes cumbersome. 4X - forget it. 

Everyone has their own look, YMMV, etc. ;-)

Nobody should confuse my comments to be negative, I
truly love this radio.

Don,

Do you really want band *stacking* memories?  A
stacking memory is 
first-in, last out, so you have to drill down through
the stack to get 
the one you want.  That seems likea much worse
situation than the normal 
band up/down switch which is a double ended stack.

If you are referring to something different, then
please do not call it 
a stack - the definition of a memory stack has been
quite clear since 
the first days of microprocessors.

John,

If you assign the 'Quick Memories' to the bands  as suggested in the 
manual (and per Windy's solution on the reflector), then you have 
exactly the same function as your TS-930 provides.  In addition, the 
K3's band up/down buttons will take you to the last used frequency on 
any band rather than to the fixed frequency you have programmed into the 
quick memories.


The only 'catch' is that the buttons are labeled '1' thru '9', so you 
have to remember which band corresponds to which button - the 
assignments are your choice.

[Elecraft] K3 Memories - Band changing etc.

[Bill Coleman N2BC]

I miss dedicated band buttons even though my main rig has been a K2 for the 
last couple years.  Using the "Quick Memories" and M1..M4 work quite well 
though.

But (you knew this was coming), the very thing that makes the "Quick Memory" 
function handy can also be its downfall. Try as I might to be careful, I 
continue to clobber the memory by pressing V>M in error.  Because the 00 - 09 
locations are "Quick Memories" they are overwritten immediately when the 
numeric keypad entry is pressed.

I would like to see either:

1) A menu entry to disable "Quick Memory" function for storing (V>M only).  In 
other words when disabled, storing would require a second V>M keypress just 
like the rest of the memories.

or

2) A menu function to LOCK the "Quick Memory" areas.  This would require 
changing the menu entry to "QUICK" or "NORMAL" before entering anything in the 
"Quick Memories".

or

3) A combination of 1 & 2 to give the 00-09 locations a selection of QUICK / 
NORMAL / LOCK.

I'm sure there are many contest operators that will use the "Quick Memory" 
function during the heat of battle.  A menu approach would not take anything 
away from that use.

Just my $0.02.  By the way, I "grew up" on DX-35s, Apaches, Drake 2Bs, HQ-170s 
etc etc ,even with an occasional "AW s&^$" when I clobber a memory, band change 
is a whole lot quicker!

Re: [Elecraft] K3 Band changing...Devils Advocate...

[W6NEK]

Hi Dave,
I think the "Band Stacking Register" definition came from the way Icom 
implemented it on their 756PRO series of radio.  This is taken from the 
IC-756PROIII operating manual on page 24:


"The triple band stacking register provides 3 memories
in one band. 3 sets of a frequency and operating mode
on each band are automatically stored when used.

If a band key is pushed once, the frequency and operating
mode last used are called up. When the key is
pushed again, another stored frequency and operating
mode are called up.

This function is convenient when you operate 3 operating
modes on one band. For example, one register
is used for a CW frequency, another for an SSB frequency
and the other one for an RTTY frequency."

The 756PRO series of radio has 12 dedicated "Band Keys" which allows this 
kind of user interface.  To implement this on the K3 in hardware is simply 
not possible.  As I mentioned in a earlier post, it has been achieved using 
PowerSDR & LP-PAN.


When not using PowerSDR I simply enter the 1st two digits of the band I want 
to go to and press enter.  Works for me.


Best 73,
Frank - W6NEK

to

a neophyte? Right now, it seems intuitive to use as is, but then again, it
is all I know and I'm sure that in the heat of the battle there may be a
better way.

I just discovered a new way to abuse the K3 using this system. I programmed
my Quick Memories to take me to frequencies in the CW part of each band,
then M1 - M4 to take me to different parts of the band.

So after pressing M>V, 5 to take me to 15m (CW) I pressed M>V, M3 to go to a
different part of the band. Only either I didn't press M>V hard enough so it
didn't register, or I had a senior moment and didn't press it at all, so I
transmitted the programmed contents of memory 3 at 100W into an untuned
antenna.

If you use the message memories then there is a risk of accidentally
transmitting their contents if you are using the same buttons as per-band
memories as well.

Re: [Elecraft] K3: too easy to overwrite dial memories

[K9ZTV]

Guys . . .

This is much ado about nothing.  Just LEARN how the K3 does memory 
storage and retrieval and it will become second-nature to you.


During the first week or two following assembly I overwrote some 
memories a time or two myself . . . until I trained myself not to.  In 
the nine months since, I have not overwritten anything.


As has been said for a full year now, the K3 is a complicated piece of 
gear.  At least initially.  A complicated radio requires understanding 
and effort on the owner's part.  If you wish not to exert the required 
effort (no shame in that), there are several good entry-level rigs out 
there by competent manufacturers, both foreign and domestic.  But there 
is no reason to demand reinvention of the front panel and associated 
circuitry merely because you find certain features awkward at first.

[Elecraft] K3 Band changing...Devils Advocate...

[Don Rasmussen]

>>> The 756PRO series of radio has 12 dedicated "Band
Keys" which allows this kind of user interface.  To
implement this on the K3 in hardware is simply not
possible. <<<

The K3 does not have 12 keys to dedicate the the
function, so covering -all- bands may not be possible,
but there are 5 DVR keys, which could be reassigned
to allow 2X or 3X stacking of your 5 favorite bands.

Some will ask - what's the point if PowerSDR can make
up the difference?, others would suggest they'd rather
leave the computer off most of the time.

Previous message: [Elecraft] K3 Band changing...Devils
Advocate... 

Hi Dave,
I think the "Band Stacking Register" definition came
from the way Icom implemented it on their 756PRO
series of radio.  This is taken from the IC-756PROIII
operating manual on page 24:

"The triple band stacking register provides 3 memories
in one band. 3 sets of a frequency and operating mode
on each band are automatically stored when used.

If a band key is pushed once, the frequency and
operating mode last used are called up. When the key
is
pushed again, another stored frequency and operating
mode are called up.

This function is convenient when you operate 3
operating modes on one band. For example, one register
is used for a CW frequency, another for an SSB
frequency and the other one for an RTTY frequency."

The 756PRO series of radio has 12 dedicated "Band
Keys" which allows this kind of user interface.  To
implement this on the K3 in hardware is simply 
not possible.  As I mentioned in a earlier post, it
has been achieved using PowerSDR & LP-PAN.

When not using PowerSDR I simply enter the 1st two
digits of the band I want to go to and press enter. 
Works for me.

Best 73,
Frank - W6NEK

Re: [Elecraft] K3: too easy to overwrite dial memories

[David Ferrington, M0XDF]

At the risk of offending someone - computers (and the K3 has a certain  
amount of that) should be programmed to serve humanity and not the  
other way around.
I've been in IT 39 years and there was a time when I accepted that a  
human might have to work a certain way or act a certain way in order  
for the computer program to best succeed.
This is no longer the case and I don't accept that any program is so  
limited that it makes it difficult for the human.


This is what the basis of all modern computing should be. That goes  
for the K3 too, which by the way I love and am NOT complaining about,  
but I would prefer some form of confirmation step before I overwrite a  
memory.
This does not need to be a sting of 'Are You Sure', 'Are You Really  
Sure You Want To", 'Are you sure you DONT want too'! - just something  
like a contiguous two button press or one button twice is sufficient  
and that should be configurable for those that don't want that feature.

[Elecraft] hello to all K2/100 owners, advise needed

[John Klokis]

I recently got my K2 serviced and updated.  I was told by the technician that I 
needed to tighten the mounting screws on Q1 and Q2 after 10 to 12 hours of use. 
Failure to do so could destroy the transitors. I have read the KPA/100 manual 
and it says to tighten these mounting screws after initial use.  My radio is 6 
years old.  Do I still have to try and remove the board to tighten these 
mounting screws periodically when using high power(100 watts).  If so needed, 
can I access these mounting screws easily or do I have to remove the KPA100 PCB?
My K2/100 and KAT100 really performs well since it was updated and 
correction of a problem fixed.  I do not work on radios, but I would try and do 
this maintanence if needed to prolong the life of the transitors.  John K3JK

You will find that the rubber buttons on the K3 do not offer the same

No, it only has to be done once after initial assembly or whenever the 
transistors have been removed.



If so needed,
can I access these mounting screws easily or do I have to remove the
KPA100 PCB? 


You need to take the shield off of the KPA100, but you do not need to 
remove the board.

[Elecraft] K3: overwriting memories? - Try this!

[DOUGLAS ZWIEBEL]

When I was first loading all the memories (I mean band switch), I too
hit the wrong sequence a few times and "messed up."

(See my suggestions:
http://mailman.qth.net/pipermail/elecraft/2008-March/084937.html )

But once they were loaded, I "found" an easy way to NOT overwrite what
I had entered.  Instead of READING what the buttons say and figuring
out what that means (apparently a stumbling block for me), I just
always go to the one in the top, right-hand corner first.  It's easy
to do...a "no brainer" - and I qualify!  Do things by rote...take the
"thought" out of the loop and you'll be fine.

Since then, I have NEVER accidentally overwritten an existing
(programmed) memory.  Top right-hand corner is a great location!

Try this simple approach.  It works for me!

[Elecraft] K3 and CW problem

[Larry]

I have a new K3 that I just got up and running. I am having a problem on CW
mode.

I have a 500 and 250 CW filter installed and both work the same with this
problem.

When I spot a station and get right on frequency the volume drops off to the
point of almost disappearing.

If I tune 40 to 50 hertz above or below the zero beat point the volume comes
back up.

I have double checked all my filter settings and the RX equalizer is set
flat. NOTCH is off also.

I've checked all the Menu items and do not see anything out of wack.

Basically, when I tune a station spot on the volume drops to nothing.

Anyone have any ideas? What am I missing?

If the thermal pads for the PA transistors were replaced then you DO 
need to re-tighten the screws after 10 - 12 hours of use. Check with 
the technician who serviced and updated your K2 to see if they were replaced.

RE: [Elecraft] K3 and CW problem

[Dick Dievendorff]

I'm going to make a guess that the filter offset you've dialed in isn't
negative.

Would you connect your K3 to your PC, start the K3 Utility, navigate to the
Configuration Tab, click "Edit Crystal Filters..." and verify that all the
settings are correct?  The frequency offset for a 5-pole crystal filter is
usually negative. Do the offset values match those printed on your crystal
filters?

If you can, please capture a screen shot. Click the title bar of the crystal
filter window, press Alt-PrtSc, then open the Windows "Paint" program and
paste (with Ctrl-V) the image into paint, save it as a .jpg file and send it
to me.  Alternatively, save your configuration and send me the .k3config
file.  I'll also need to know what filters you have, what slots you
installed them in, and the frequency offset value that's printed on the
5-pole filters.

Subject: [Elecraft] K3 and CW problem

I have a new K3 that I just got up and running. I am having a problem on CW
mode.

I have a 500 and 250 CW filter installed and both work the same with this
problem.

When I spot a station and get right on frequency the volume drops off to the
point of almost disappearing.

If I tune 40 to 50 hertz above or below the zero beat point the volume comes
back up.

I have double checked all my filter settings and the RX equalizer is set
flat. NOTCH is off also.

I've checked all the Menu items and do not see anything out of wack.

Basically, when I tune a station spot on the volume drops to nothing.

Anyone have any ideas? What am I missing?

[Elecraft] K3 and CW problem

[Larry]

Dick

 I appreciate your help in this matter but I discovered the problem. It is
not the radio but my headphones. I have a pair of Kenwood HS-5 headphones
and it seems they have a real dip in output below about 700Hz. I have the
sidetone set at 650 Hz.

 When I tried a different set of headphones the problem went away. I never
noticed that the speaker didn't do this either. 

 I am kind of surprised that the HS-5 headphones have this noticeable dip in
output at this range and I am surprised I never figured it out before this
as I have been using these phones with my K2. But as I think about it this
explains some things I noticed with my K2 but never figured out.

I'll post to the list tomorrow as this might be interesting to others to
know that some headphones output really drops at the lower frequencies.

I'm going to make a guess that the filter offset you've dialed in isn't

negative.

 

Would you connect your K3 to your PC, start the K3 Utility, navigate to the

Configuration Tab, click "Edit Crystal Filters..." and verify that all the

settings are correct?  The frequency offset for a 5-pole crystal filter is

usually negative. Do the offset values match those printed on your crystal

filters?

 

If you can, please capture a screen shot. Click the title bar of the crystal

filter window, press Alt-PrtSc, then open the Windows "Paint" program and

paste (with Ctrl-V) the image into paint, save it as a .jpg file and send it

to me.  Alternatively, save your configuration and send me the .k3config

file.  I'll also need to know what filters you have, what slots you

installed them in, and the frequency offset value that's printed on the

Re: [Elecraft] K3: overwriting memories? - Try this!

[Tony Fegan VE3QF]

   I went a step further and put a piece of white 1/4 inch masking tape 
over the V>M key. Not pretty but it works for me. It is just enough to 
catch your eye and of course when you really need it, it can still be 
depressed. I do have an "advantage" in that with poor eyesight it is not 
easy to read and mix up the keys!
   My band memories are set similar to yours Doug. I have my most used 
frequency in VFO-A and my second most used frequency in VFO-B. I operate 
mainly SSB but monitor the other modes. I have not used the band up/down 
for 3 months.

(See my suggestions:
http://mailman.qth.net/pipermail/elecraft/2008-March/084937.html )

But once they were loaded, I "found" an easy way to NOT overwrite what
I had entered.  Instead of READING what the buttons say and figuring
out what that means (apparently a stumbling block for me), I just
always go to the one in the top, right-hand corner first.  It's easy
to do...a "no brainer" - and I qualify!  Do things by rote...take the
"thought" out of the loop and you'll be fine.

Since then, I have NEVER accidentally overwritten an existing
(programmed) memory.  Top right-hand corner is a great location!

Try this simple approach.  It works for me!

RE: [Elecraft] K3 and CW problem

[Dick Dievendorff]

Wow, that is an interesting result!

Evidently my guess was wrong.  Thanks for the follow-thru message.

I think I have a pair of those phones somewhere, but I found them too tight
to be comfortable.
