I notice up to a +10dB pop on the leading edge of cw elements with my
Omni 6+.  Please see a recorded waveform at

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
