[Elecraft] K3 AGC attack rate

Gary,

There are several AGC parameters that overlap, so I don't know which one 
is creating the most grief for you.
I encourage you to try adjusting the AGC threshold and slope as 
indicated in my "Noisy K3" article on my website www.w3fpr.com.  I would 
think the slope parameter might be effective in reducing the effect of 
your local noise spikes.

It may be better to let the AGC handle the noise spike, but reduce the 
delay so the reduction of gain is shorter.  A bi of experimentation with 
all the AGC parameters may be in order.

73,
