Barry: The only thing I have found is the note from Paul W9AC dated 8/28/2004.
The text can be found at www.qsl.net/tentec/mods/563key.htm , basically it says
to
disconnect plug 52 on the if/af board.
I never noticed the problem, but my ear is not that "refined"! HI

Subject: [TenTec] Omni6/Omni6+ AGC pop on cw leading edge
I notice up to a +10dB pop on the leading edge of cw elements with my
Omni 6+. Please see a recorded waveform at
http://n1eu.com/omni6agc.gif
and the accompanying 20sec recording is at
http://n1eu.com/omni6agc.wav
It's clear that when there's been no signal for a second or so, the
big 10dB pop is much more likely. Otherwise there's a "little" pop of
3-5dB. I'm not seeing much in the archives but has anyone tried to
tame the "pop" via AGC time constants etc? Can anyone contribute a
little technical analysis?
I see little difference in the popping with fast vs slow AGC.
Thanks & 73,
Barry N1EU
