Eric,

Any particular diode you recommend?

IMPORTANT -  If you do this, make sure to protect the P3 IF input with back
to back diodes. Static electricity on the whip antenna can harm the input
pre-amp. (Ask me how I know..)

I made an adapter here with a male-female BNC terminator with the back to
back diodes internally instead of the 50 ohm resistor.

I power the P3 with a 10 cell AA alkaline battery pack to search for RFI.
