check all your cabling and the cans, all it takes is a bad connector
or coax to shut your system down, that fact you can get in to it at 2 miles
tells me your rx amp has failed, or there is a short in the cabling between
the module and antenna... 1 lightning hit is all it takes to kill a system.
Does it receive better in low power than it does in full power? If so, the
problem is desense. What is your antenna/duplexer situation?

Hi Lot,
The issue with the Icom UHF repeater hardware is that the receiver has poor
selectivity (immunity to off frequency and out of band transmissions) and poor
sensitivity.
You need a lot of RF separation between the transmitter and receiver ports...
100dB or better is what you need. You

ALL of the internal RF cables MUST be replaced!!! EVERY repeater they
made and make uses crap coax!!
Good Luck!

Hello Everyone,
Thanks to all the information that you guys provided. This is very much
appreciated. We will look into this and hopefully it would work out.

A few months ago, the same digital repeater was setup in Mt. Lukens in Los
Angeles and in the same setup where an analog repeater used to be. Right away
we noticed the difference in receive sensitivity. We made some test at a low
level location and that is where we realized that even in
