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

[C.L. Mitchell]

On my Viking II the antenna relay output socket fits a HC-6/U crystal holder.  Made a plug for it using an ancient CB crystal and took care of the bare wire 110 V issue [and made good use of a CB xtal].  IIRC, Johnson used the same socket on a lot of their transmitters.  And I just make or find a plastic covering for the Dow-Key type relay terminals.
