Tom,
I agree with all but would use the the shunt diode clamp in conjunction with
an open realy contact or other means to prevent
the rf being rectified in the diode clamp and causing more trouble.IOW, use
the diode clamp as the last/final barrier but with a means to reduce the rf
to the diodes?

PS:QRN very high here for days now, preventing all but the strongest
stations to be heard.
