Re: VHF MTR2000 Poor Receive Performance

 

I may have missed something but have you tried this ?

Hook a transceiver to the antenna and see what kind of range you are getting.? If as expected, hook the repeater receiver input directly to the antenna and see if you are getting about the same from a distant station.

Have you tried cutting the transmitter off and on while receiving a signal to check for desense ?

When you injected the signal did you up it a db or two to compensate for the loss in the duplexer ?

So last night, I measured the MTR at 0.4uV at the receiver port and 0.5uV at the duplexer antenna port.

I injected a signal into the receiver port of the MTR that had just barely had no noise and when I injected it through the duplexer into the repeater, there was noise present. It wasn't heavy noise but it still had noise on the signal.
