Thanks Greg, I'm using Radio Shack remote speakers. They're very
small cube shaped speakers with mono mini-plugs on the end of
about a 10' wire. As I said, they're unpowered. I just have them
plugged into the aux speaker out connection on the radios.
Can you tell me more about the GE MASTR units?

Thanks


Mike,

I do not know what radio mfg. or models you are using, but I believe that
one of the GE MASTR heads had an option for an LED (or bulb) to perform
such
a function.
