[TenTec] RF in Ext. Speaker on Jupiter

[Phil Sussman]

Once upon a time I had a problem like that. The thing I noticed was that when I 
keyed up, it would peg a nearby CB FSM. Taking that as a clue, I made up a 
sniffer coil and wired it to the antenna input of the FSM. 

What I discovered was bad solder on a PL-259 connector on the back of my amp. 
It had tested OK with an ohm-meter, but apparently the shield was not making 
good contact with the shell of the connector.

For RF to get into a speaker you must have exceeded the FCC radiation exposure 
limits, eh? 

Good luck!
