The way CBers using power mikes and linears were dealt with was to stick a pin
through their antennas' coax feeds.

As crappy as much consumer electronics is made, probably a tone-modulated ham
or CB rig with 100 watts or so might get into the guy's gear and demodulate
somewhere, if there's such a thing as a high gain stage in solid state audio
stuff. Back in the old tube days...
