See below.? The high "Smooth Samples" setting seems to eliminate much of the audio clicks.? The remaining settings give reasonably good dynamic range while limiting strong signals. I'm still experimenting with values but this is a good start.

I have just tried this and smoothing makes no difference to the clicking for me.? It seems much more related to the AF gain with the clicking being very much reduced with the AF gain turned down and seems to be related to the clunking that is sometimes present when keying on older firmware versions.? With S9=S9 the clunking is very pronounced and makes keying barely possible.? With S9=S0 then this is reduced to the spark like sound and with the AF gain dialled down becomes perfectly manageable but present.? However I have not tried it on air to see if the incoming signal will be loud enough to hear.
