Bob, et al,
I installed the Koss UR40 pads on the CM-500 headset. I can't remember which
video but the Yamaha and Koss are the same size pads.

Re: [Elecraft] K3: Odd ALC behavior

[Brian Hunt]

The "TUNE" tones from both applications (FLDIGI & WSJT-X) looks like a single 
frequency and is a pretty decent sine wave on the scope, although "pretty 
decent" is hard to quantify. It's more like the 500 Hz and its harmonics are 
beating with some process within the K3. The "pulsing " isn't apparent in the 
RF output power, at least as far as I can measure, so it may just be an audio 
artifact. Moving off those frequencies is certainly a work around for setting 
the audio drive level.

Re: [Elecraft] New release of Win4K3Suite

[Clay Autery]

Awesome!!!  Thanks, Tom!  It just keeps getting better and better!

Note...  Once you open the drop-down and a value is highlighted, you can
use the arrow keys to go up and down the list while listening instead of
futzing with the mouse each change... 

Right Click on NR, Left click on displayed value, then arrow up or down
one click per setting choice...

Also finally started using the TX EQ presets  For some reason, my
radio frequently loses my standard setting: 
(-16,-16,-16,-12,0,0,+3,+3)  Now that it's in a preset, it'll only take
one click to restore it!

LOVE this software!

Re: [Elecraft] OT Yamaha CM-500 ear pads

[mpupeza mpupeza]

I ordered Koss UR40 cushions from Koss and they were $5.00 + $0.35 Tax (S+H
FREE) to my Winter Home in Florida. Perfect fit but snug and awkward to install.
I looked how to do them on Youtube. There are several screws to loosen under the
rim of the old ones. They were mail delivered in less than a week. Much cheaper
than a new headset.

Re: [Elecraft] K3: Odd ALC behavior

Is it possible that a beat note between tones (and their harmonics) is what’s 
modulating the ALC reading? If so, moving the tone slightly off the standard

Re: [Elecraft] KX3 Heat Sink

[Wayne Burdick]

David,

The new heat sink roughly doubled key-down time in our lab tests. I’d suggest 
you try it as-is before investing in a third-party heat sink. I use RTTY at 
full power on my KX3 with just the new stock heat sink and have never had an 
issue.

[Elecraft] New release of Win4K3Suite

[Tom]

Hello,
There is a new release of Win4K3Suite for the Elecraft K3-S, KX3, and KX2.  
This release provides support for a few firmware changes in the K3 current beta 
and future release.
In addition, the Noise Reduction control now supports setting the level of 
noise reduction by right clicking the NR button and selecting one of 32 
different levels.  It fun to play around with this control to see the 
difference it can make.

Win4K3Suite is the ultimate computer control and integration program for your 
Elecraft Radio.  It interfaces with all Elecraft hardware allowing even the KX2 
to control and integrate the KPA500 and KAT500.  In addition, it has built in 
virtual port technology which allows up to 4 software or hardware devices to 
share the radio.  It integrates with HRD LogBook and DM780, DXLab, Log4OM, 
WSJT-X, N1MM+, you name it!

You can see an overview here:
https://www.youtube.com/watch?v=htVlc9x0IoU

and some reviews here:
http://www.eham.net/reviews/detail/11214

Check out how to use the built in Spectrum Scope!

Re: [Elecraft] KX3 Heat Sink

[k1szo]

Hi Jim,

I recently purchased my KX3 and intend on doing a lot of digital modes.  
I looked into 3rd party heatsinks, but was notified that Elecraft uses a 
new improved heatsink that wraps around the bottom of the KX3.


So my question to you is, do you have the newer KX3 Elecraft heatsink or 
the older model?  I was going to work mine first to see how hot it gets 
before making a move if the newer heatsink is acceptable.   I can't find 
any reviews of it.


I will definitely be watching this thread to figure out if I too want to 
purchase the 3rd party Pro Audio Engineering KX32 Ultimate Heatsink as a 
replacement.


Regards,
David ~ K1SZO

Re: [Elecraft] KX3 Heat Sink

[k2ud]

Of all of the aftermarket KX3 heatsinks, the VE7FMN has the most surface area 
and mass- read that, it will be the coolest albiet heaviest heatsink you can 
add to the rig.  I have one on mine, run RTTY and PSK31 a lot and never notice 
much in the way of heat at all with the heatsink.

Look at http://VE7FMN.CA for more info.

Good find Brian!!! I see it too in FT8.

This probably explains the great variability in results reported. Some of us 
have a problem, others say, Huh, what the heck are you talking about?

Re: [Elecraft] K3: Odd ALC behavior

[Mike Harris]

A blast from the past, it's been 17 years since I was involved with this 
stuff.


In E1 PCM multi channel voice transmission systems the standard test 
tone was 1024Hz so as not to interact with the 8kHz sampling rate.


This is not a fault but a fact of life.

Maybe the designers would care to mention the DSP sampling rate for the 
TX audio.

This looks like a beat between the modulating frequency and some
sampling process associated with the ALC meter.

[Elecraft] OT: For Sale: 4-band KX1

[Phil Hystad]

I am selling my 4-band KX1, 80,30,40,20 meter bands.  This KX1 is in excellent 
condition.  The KX1 has been discontinued so maybe someday this rig will be a 
collectors item or maybe have a place in a museum somewhere (Smithsonian?).

I built the KX1 myself, very first Elecraft kit I built.  I did the 40,20 band 
kit and I bought the 80,30 band kit at the same time but never got around to 
building it.  A few years pass and finally I sent it to Don Wilhelm to build.  
Having passed thru Don’s hands you can expect the excellent work he did.  

I never did buy the antenna tuner as I bought the T1 instead because I had 
other QRP rigs that I also used the T1 with.  However, judging by the Order 
list on Elecraft, I am assuming you can still purchase the antenna tuner kit.

Price:  $250 includes shipping CONUS.  Included in shipping is KX1 and all KX1 
documentation. Payment by PayPal requested.

Please contact off the list if interested.

Re: [Elecraft] K3: Odd ALC behavior

[Bob McGraw K4TAX]

I did a spot sweep in 100 Hz steps from 1000 Hz to 2000 Hz using TUNE 
function on WSJT-X.  I observed, depending on frequency of the tone, the 
value of ALC indicated does change.  This to me indicates the uniformity 
of the filter does show some ripple across the top.  This is normal in 
my thinking.


So when setting levels, select a mid range tone and let the others fall 
where they may.  In any event, you won't be far from the ideal level.

Hi,

I have an issue in  regards to obtaining 4 bars, and getting the 5th 
bar of ALC to fluctuate while transmitting JT65.


I have plenty of audio, and can drive the ALC to 6 or more bars if I 
turn things up.  However, as I get to 4 bars with the 5th flashing a 
bit, the ALC starts to fluctuate between nothing and 4 or 5 bars...


That is to say, the ALC just goes to zero, no visible ALC, and then 
teh ALC returns to 4 or 5 bars.  This happens across a one or two 
second time span.


The ALC is at zero more than it is above zero most of the time. If I 
run it to five bars, with the fifth fluctuating, all is well, there 
seems to be some sort of threshold at the 5th bar of ALC...


I have tried a number of things to try and triage this...  For instance:

1.  Running in "Transmit Test" mode to eliminate RF feedback.
2.  Upping the audio level feeding the K3.
3.  Reducing the audio level feeding the K3.
4.  Upping the line in on the K3 setup.
5.  Reducing the Line in on the K3 setup.
6.  Adjustment of the WSJT-X output level control, under conditions 2 
through 5 above.


In all cases the above described behavior of the ALC dropping to zero 
does not change in any way if I am at 5 or less bars.  That is to say, 
if I take the ALC level to 4 bars, it starts dropping to zero more 
than not...


Does anyone have any suggestions as to what this might be?

A a bit of history-- the computer and sound card were used on an Icom 
756 ProIII, and there was never an issue like this...  The ALC was 
adjustable from zero to too much on the Icom, with no dropouts...

[Elecraft] KX3 Heat Sink

[Jim Ruff via Elecraft]

I've been doing a lot of FT-8 using my KX3 and my KXPA100 at 20 watts, and have 
noticed that the KX3 is heating up quite a bit and is almost hot to the touch.  
The KXPA100, while warm, appears to be okay.  Should I consider purchasing a 
heat sink for the the KX3? If so, what products in your opinion are the best?

Thanks,JimW7JHR

Re: [Elecraft] K3: Odd ALC behavior

[Brian Hunt]

I spent some quality time with my K3, FLDIGI and an oscilloscope today.  
I had the same problem as described.  Looking at my USB soundcard output 
to the K3, the amplitude of the audio from FLDIGI in TUNE mode was rock 
solid.  Looking at the MON output from the K3, the level oscillated in 
time with the ALC "pumping" at about 2.4 Hz (timed with a stop watch).  
At the same time the K3 power output into a dummy load was rock solid at 
a selected 10 watts.


Then I changed the carrier frequency in FLDIGI slightly off 1500 Hz and 
the "pumping" went away!  At 1515 Hz I could easily set the ALC to the 
desired 4 bars solid, 5th flickering.  Then I remembered (and verified) 
that the default filter center in DATA A mode is 1500 Hz. I changed the 
filter center frequency to 1450 Hz and moved the FLDIGI frequency around 
but couldn't reproduce the "pumping".


I plan to repeat the same tests with WSJT-X 1.8 but wanted to get this 
out to the group.

Hi,

I have an issue in  regards to obtaining 4 bars, and getting the 5th 
bar of ALC to fluctuate while transmitting JT65.


I have plenty of audio, and can drive the ALC to 6 or more bars if I 
turn things up.  However, as I get to 4 bars with the 5th flashing a 
bit, the ALC starts to fluctuate between nothing and 4 or 5 bars...


That is to say, the ALC just goes to zero, no visible ALC, and then 
teh ALC returns to 4 or 5 bars.  This happens across a one or two 
second time span.


The ALC is at zero more than it is above zero most of the time. If I 
run it to five bars, with the fifth fluctuating, all is well, there 
seems to be some sort of threshold at the 5th bar of ALC...

Re: [Elecraft] K3: Odd ALC behavior

[Don Wilhelm]

Glenn,

That method will give you a bad indication of the power output.
Elecraft transceivers use a closed loop power control system - as found 
in some commercial transceivers, but as far as I know, not in other 
amateur transceivers.


The result is that an Elecraft transceiver (K3, K3S, KX3, KX2 and yes 
even the K2) will endeavor to provide the power level that was set with 
the power knob.  That can cause some of the transmit gain stages to go 
to their maximum output limit - which will increase distortion.


Set the audio level first as described by Elecraft, and after that, set 
the power level desired with the power knob.

Leave the audio level alone after setting it.

Ignore the common internet advice, it does not work well with Elecraft gear.

Hi Glenn,

Respectfully, the issue, as already stated a few times, in several messages, is 
not that no one knows what to adjust, and we are all over thinking how to fix 
this, but that it is not possible to get the desired results, no matter what 
one adjusts.

I have adjusted all possible combinations of level controls-- LINE IN on the 
K3, the sound card out on the computer, and the Power Out on WSJT-X, to get to 
the desired results, and have failed.

Given that I am a pretty creative fellow, and spend decades in the Electronics 
industry, I suspect I am doing this correctly, so no, I am pretty sure this is 
not a case of over thinking, but of something not visible happening.

I just read Ken's post of July 16th, and yes Ken's problem sounds like the same 
issue I have-- as one approaches the correct settings, the K3 jumps to 
instantly to 5 bars, skipping 4 bars, or as you lower any input to the K3, the 
ALC actions simply stops at 5 bars...  Then te ALC levels start to pump, while 
power out stays the same...

I have heard this described as Power Hunting before, but in my case, it seems 
totally disconnected from any power settings I run.  I have tried everything 
from 1 watt to 100 watts, and the behavior never changes.

Alas, I fear I will just continue running with a bit of ALC, which I don't want 
to do...  I would like to set it up as per Elecraft recommendations, but that 
seems impossible.

Thanks to all for the sheer number and breadth of answers...  Rather

and answer all here...

I have done all the steps outlined i the posts here before, and have
tried them again today.

Output from the computer is sitting dead center, line in was sitting
at 27, and the power slider on WSJT-X is sitting at 4/5th full.

I took a different sound card program, (MixW in RTTY), and I got the
same behavior at 5 bars, the meter shows 5 bars, or no bars going
between those conditions about once or twice a second randomly.

If I increase ANY of the audio controls it drops out of that mode, and
acts just as Elecraft say to set things, just one bar higher, i.e.
sits at 5 bars, and the 6th flashes...

No combination I can create of the input, or output controls will stop this.

I also tried adjusting the power controls set a 1 watt, and at 50 watts.
The power control makes zero difference in how it behaves.  In fact
if I am in TEST TRANSMIT mode the problem shows...

Listening to the computer output via MON-- sounds perfect...

I may next get the scope out again, and start looking at things again...
I doubt it is the sound card changing levels because the issue goes
away if I turn up LINE IN on the K3...

I am still at a loss as to what is causing this issue.  I am pretty
sure it is an artifact of something happening in 

[Elecraft] K3S Odd ALC Behavior

[Bob McGraw K4TAX]

I posted a video in my Dropbox at the link below.It shows 4 ALC bars 
solid on and the 5th flickering.


https://www.dropbox.com/s/an06t907tx8xgid/Video%20Aug%2004%2C%208%2012%2025%20AM.mov?dl=0 



I find that anytime where any the controls are running at near a minimum 
value, the granularity of the steps is significant.  {i.e. big steps = 
big changes}Where as operating near mid range to upper mid range,  
one has better control of the levels, meaning there is less change per 
step.


Also with WSJT-X I find that trying to grab the PWR slider and move it 
up or down with the mouse is a bit of a challenge.  The mouse 
acceleration will cause significant changes.It is easier to position 
the mouse cursor on the line and click above or below the slider to 
attain a fine adjustment.   This way it will only move to the next 
step.  Don't hold the left mouse button down or the slider will move to 
the position of the mouse cursor.


As stated before, there's three places where the levels must be adjusted 
and they do interact as they are fundamentally in series.


(a)   Speaker level -  nominally about 25 to 35

then to

(b) WSJT-X PWR level - nominally about mid to upper mid range

then to

(c) K3S Line gain - 25 to 35

Re: [Elecraft] K3: Odd ALC behavior

[Walter Underwood]

This is right for most ham transmitters, but wrong for Elecraft. Elecraft 
transmitters have a closed-loop power control that will try to keep the power 
at the set level (50 W) regardless of the audio input.

1. Set output power to 0 W and/or use a dummy load.
2. Set WSJT-X to “Tune”, where it will put out a constant tone.
3. Adjust all audio levels, starting at a middle position, until you have 4 
bars solid and the 5th flickering. It might not flicker for this solid tone.

Hi Glen,

Thank you for the info, that is essentially what I am doing.  I am

the desired results, and have failed.

Given that I am a pretty creative fellow, and spend decades in the Electronics 
industry, I suspect I am doing this correctly, so no, I am pretty sure this is 
not a case of over thinking, but of something not visible happening.

I just read Ken's post of July 16th, and yes Ken's problem sounds like the same 
issue I have-- as one approaches the correct settings, the K3 jumps to 
instantly to 5 bars, skipping 4 bars, or as you lower any input to the K3, the 
ALC actions simply stops at 5 bars...  Then te ALC levels start to pump, while 
power out stays the same...

I have heard this described as Power Hunting before, but in my case, it seems 
totally disconnected from any power settings I run.  I have tried everything 
from 1 watt to 100 watts, and the behavior never changes.

Alas, I fear I will just continue running with a bit of ALC, which I don't want 
to do...  I would like to set it up as per Elecraft recommendations, but that 
seems impossible.

Re: [Elecraft] K3: Odd ALC behavior

[Dave Cole]

Hi Glenn,

Respectfully, the issue, as already stated a few times, in several 
messages, is not that no one knows what to adjust, and we are all over 
thinking how to fix this, but that it is not possible to get the desired 
results, no matter what one adjusts.


I have adjusted all possible combinations of level controls-- LINE IN on 
the K3, the sound card out on the computer, and the Power Out on WSJT-X, 
to get to the desired results, and have failed.


Given that I am a pretty creative fellow, and spend decades in the 
Electronics industry, I suspect I am doing this correctly, so no, I am 
pretty sure this is not a case of over thinking, but of something not 
visible happening.


I just read Ken's post of July 16th, and yes Ken's problem sounds like 
the same issue I have-- as one approaches the correct settings, the K3 
jumps to instantly to 5 bars, skipping 4 bars, or as you lower any input

I have done all the steps outlined i the posts here before, and have tried
them again today.

Output from the computer is sitting dead center, line in was sitting at 27,
and the power slider on WSJT-X is sitting at 4/5th full.

I took a different sound card program, (MixW in RTTY), and I got the same
behavior at 5 bars, the meter shows 5 bars, or no bars going between those

If I increase ANY of the audio controls it drops out of that mode, and acts

bars, and the 6th flashes...

No combination I can create of the input, or output controls will stop this.

I also tried adjusting the power controls set a 1 watt, and at 50 watts.
   The power control makes zero difference in how it behaves.  In fact if I
am in TEST TRANSMIT mode the problem shows...

Listening to the computer output via MON-- sounds perfect...

I may next get the scope out again, and start looking at things again...
   I doubt it is the sound card changing levels because the issue goes away
if I turn up LINE IN on the K3...

I am still at a loss as to what is causing this issue.  I am pretty sure it

Re: [Elecraft] OT: About Grid Squares

[Martin]

Another great tool to determine a locator or the distance between 2 
locators is:


http://qthlocator.free.fr by F6FVY

It uses google maps. Just enter a known locator or  click on a known 
location (e.g. your house) and voila. Maybe it is one of the fathers of 
that sort of tools. I've first seen it 12/2006.

You guys are over-thinking this "issue". Just set whatever combination of
level controls it takes to get four solid bars and a flashing fifth on the
ALC and get on with it.that works for me.

Thanks to all for the sheer number and breadth of answers...  Rather than

all here...

I have done all the steps outlined i the posts here before, and have tried
them again today.

Output from the computer is sitting dead center, line in was sitting at 27,
and the power slider on WSJT-X is sitting at 4/5th full.

I took a different sound card program, (MixW in RTTY), and I got the same
behavior at 5 bars, the meter shows 5 bars, or no bars going between those
conditions about once or twice a second randomly.

If I increase ANY of the audio controls it drops out of that mode, and acts
just as Elecraft say to set things, just one bar higher, i.e. sits at 5
bars, and the 6th flashes...

No combination I can create of the input, or output controls will stop this.

I also tried adjusting the power controls set a 1 watt, and at 50 watts. 
  The power control makes zero difference in how it behaves.  In fact if I
am in TEST TRANSMIT mode the problem shows...

Listening to the computer output via MON-- sounds perfect...

I may next get the scope out again, and start looking at things again... 
  I doubt it is the sound card changing levels because the issue goes away
if I turn up LINE IN on the K3...

I am still at a loss as to what is causing this issue.  I am pretty sure it
is an artifact of something happening in the K3, but for the life of me I
can't figure it out.

Re: [Elecraft] [K3] Using K3 for relative noise survey

[David Cutter via Elecraft]

Apologies for taking this away from Elecraft topic, however, you might be 
interested in a specific noise measurement system here:

http://www.crosscountrywireless.net/sentinel_2_sdr.htm
in which a *calibrated* sdr is programmed to continuously listen on 5 unused 
HF frequencies and report to APRS every 10s.

Rick,
While it is not easy, you should put in the agenda checking it day and 
night. I found very different noise profiles that way

Thanks for all the info!

It turns out I have an RSP2 and now have it running with HDSDR in "slow"
waterfall mode. I'm now looking for a way to control the front end options
of the RSP2 - nothing seems to be built into HDSDR to do that, but that's 
a
topic for another mail list. BTW - I conveniently have an EXCELLENT 
Clifton
Labs 1800 KHz AMBC high pass filter that sure tames the input dynamic 
range

when measuring 160M.

I will also try the suggestions for different ways to record signal 
strength

on the K3.

Thanks again,
Rick
