Mark: On the Mirage amps I've seen, there are two relays. There is one
(Ry1) controlled by RF Sense, and an antenna relay (Ry2), which is
controlled by Ry1. While putting the amp in the FM position should do what
you want (It only changes how the amp keys. It always operates as a
linear). If you really want to disable the RF Sense keying, there is a
transistor (MPSA13), colllector to relay Ry1, emitter to ground. If you
remove that transistor, only external keying will work --73, Mike, WV2ZOW
