[AMRadio] Protecting receiver (was WTB: Coax relay, 110VAC, aux contacts)

[rbethman]

That is why I use an EF Johnson TR-Switch, AND use the BC-610 internal 
relay that shorts the PA tank to feed a second relay for muting.

I use the 455Kc IF output of either receiver to the input of the station 
monitor.

I figured out long time ago that when running a QRO AM station that this 
worked out very well.

I either use an SP-600 or R-390A for a receiver.
