What's the mathematical difference between AGC DCY = 'Nor' and 'Soft'?
My ears hear this: 'Nor' sounds like a linear return to normal gain while
'Soft' sounds like an x-squared or x-cubed curve back to normal gain, because

The issue is that ESD often doesn't immediately kill components. More
often it simply shortens their lifespans.

My antecdoctal evidence says it worked for me, both on the initial build
and on the removal and re-installation of the DSP board after upgrade.
I'm not going to argue with what Alan said, as I'm not qualified, but
I'm betting the health of my K3 on it, and wouldn't hesitate to pull it
out again

John,
I suspect that the power scaling for the forward and reflected power
signals is not working properly.
In high power (during a TUNE) the /FSCL and /RSCL signal go low which
effectively grounds pins 4 and 2 of RP1 - that creates a voltage divider
with R6 and R7 so the SWR calculation should
There is another point worth mentioning...if you are using a computer
that has no COM ports but with a USB-2.0 --> COM adapter, you should be
aware of the fact that many of the so-called adapters (the cheaper ones)
do not implement the entire RS-232 protocol. I mentioned this on this

It sounds like a simple idea, but I would suggest you use a very
straightforward low-level terminal program (e.g. PUTTY) to see if it can
talk to the K2. This may help to isolate which end of the RS-232 the

If you can communicate in any way with the K2 (and you *can* because you

You might try putting the RTS/CTS jumper on the connector at the

Thanks to Matt Zilner, in an offline message, this is resolved.
The problem was that my PL DEV was set to 0.0.
For anyone else who might face this problem, to adjust PL DEV, you go to FM DEV
in the Config Menu, and then touch 1 on the keypad. THe default PL DEV is
0.36.

If you have the Radio Shack mat, I recommend using it even though I'm
not convinced it does a proper job of bleeding off static charge. For
one thing, the anti-static wrist strap that comes with it does work.
For another, even though it may not prevent static build up, at least it
probably doesn't

David,
I was the one that brought this mat up (unfortunately), and all I can say is
that it was fine for putting my K3 together very successfully and I'll use
it again. I'll stop there, but will add that any time I like, after walking
across my floor here, I can draw a spark from metal objects.
So the question becomes does it work well enough for assembling
Elecraft kits even though it does not meet industry specs. Not
backing any particular horse in this race, but I know that there are
other areas in which industry specs are overkill for me.
Who knows the answer?

Problem solved.
Turned out failure of the 1 mW test was caused by a defective dummy load used
at the XVTR-OUT connector for the test.
Thanks for the many quick/detailed/in-depth responses (some by off-list
responses); fortunately this was a self-inflicted issue, unrelated to the K3 at
all.
