If the heatsink was very hot, then I would assume that the PA
transistors were working. Obviously, there are better methods to verify
this. But lets say they were working, I would check the jumper between the
PA filter boards. This is a common failure point on UHF PAs as well. Does

It is a alarm monitoring unit. With appropriate power sensors it can
monitor transmit power, SWR, various voltages, PTT, etc. It is also capable
of remotely controlling outputs for control functions. If connected to a
phone line, it can also page or call pre-programmed numbers when
That makes more sense Derek. I'm have repeaters setup this way. The bandpass
filter can probably be tuned for either receiver freq and it should work
fine on the other. You could also get a 1:2 splitter to accomplish feeding
each receiver. That way you wouldn't have to worry about the exact cable
With the repeater tx at 444.975, the second receiver would only be 25 khz
away from the repeater transmit frequency! The duplexer wouldn't pass
anything to the receiver at 444.950.

Richard,
Have you tried an additional cavity in the rx path? I had a
similar situation with a UHF repeater and 800 mhz systems and anadditional
cavity worked for my problem. Also, do you have a preamp? If so, where in the rx
path is it? You should have all the filtering ahead of
