Thanks for the input here. I thought something was a bit strange for the
distance. I'm thinking in the duplexer, but am going to have to hook the
transmitter up and have someone a distance from the repeater hear the
signal, almost bet it is there. As far as I can tell, the recieve side of
the repeater is working ok. Just no distance on the transmit. Keeps me
moving.
