Joe,
I have to change the operating tips page. It was done prior to a major ALC
change. I was waiting for another update as Lyle is changing the ALC meter
feedback. It will change to 1-bar as the desired setting. For now, you can
adjust it for 4 bars. If you cannot get 4 bars 3 is still OK.

Now I don't know what to believe. In Lyle's April 6 post, he says:
We recommend setting the Mic (or LINE IN) Gain so you get 5 bars of
ALC,
with possibly the 6th bar occasionally flickering...
Yet, on the "K3 Operating Tips" page of the Elecraft web site, in the
section about "Setting up your K3 for PSK" it says:
Use the MIC control to set the drive level so that your output is
equal or just below what you dialed in ... You should not see any
ALC bars on the K3 display (when set to CMP/ALC).
Rev D1 of the operating manual seems to agree with Lyle in that it says:
You can use the same procedure outlined for voice modes (pg. 28)
except that speech compression should not be used. [Pg. 28]: adjust
MIC for a peak ALC meter indication of about 5-7 bars.
If the operating tip on the web site is wrong, it ought to be
corrected or removed.

Richard and all,
If you look back to Lyle Johnson's reflector posting of April 6, you
will find the following: (plus other good information about setting
up data modes.
"In this case, the ALC meter display is acting as a "VU Meter" and
is being used to help you set the Tx audio path gain correctly. It
is not showing you how much you are over-driving the PA. This is
why you can set it up in Tx test mode, when you are not transmitting
any RF at all. "
Additional information can be found in Rev D of the K3 user's manual
on page 32.
