Hi Wayne --
I always get nervous when I see diodes proposed to clip strong RF.
One of the biggest problems we have in a multi-transmitter site
(DXpedition or multi-TX contest station) is IMD generated by diodes
rectifying RF and re-radiating the result back into the local
environment. Even a nearby AM BC station can induce enough voltage on
cause diodes to start rectifying.
IMHO, if some guy wants to listen to a full-power signal from <100m
away, it is his responsibility to insert an appropriate external attenuator.
I really don't want to see the performance of the K3 (AGC on or off)
compromised in any way whatsoever to handle such an atypical scenario.
