If I run it will full RF gain on a really good antenna and fast AGC there can be some popping on really strong CW. There's enough time delay in the 16 poles of filter that the gain control before the filter can't cut back on signal already propagating through the filters. If I run with RF attenuator of (RF stage disconnected) and the RF gain backed off a little and slow AGC there's no popping and I still copy all possible signals. 73, Jerry, K0CQ -- Entire content copyright Dr. Gerald N.
