[Elecraft] Where the RFI problem on K2 5087 REALLY was.

[Ron D'Eau Claire]

How easy it is to forget those "features" in commercial rigs. 

That connection us used to set the squelch or enable scan, depending upon
the commercial rig it is used with. On ships it usually enables scan so the
vhf "bridge-to-bridge" radio will be monitoring all the channels as long as
the mic is hung up. Someone calls and you need to respond so you grab the
mic which takes it out of scan when the ground on the mic hangar is broken,
and you're ready to talk.
