[Elecraft] P3 Noise signature

[Eric Swartz - WA6HHQ, Elecraft]

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.
