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.
73s and thanks,
Dave

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.
See Y'all on FT8!

Subject: Re: [Elecraft] K3: Odd ALC behavior
Thanks to all for the sheer number and breadth of answers... Rather than
answer each one, and create a huge number of posts, I will try 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 the K3, but for the life of me I
can't figure it out.
73s and thanks,
Dave
