Try disconnecting receive coax from repeater and connecting it to another receiver on the input frequency
Then, open the squelch on the repeater and have someone with variable power transmit from 5 miles out on the input frequency and record how much power it takes to achieve full quieting of their signal on the other receiver. This will help you determine if de-sense is caused within the repeater, or if it is duplexer induced. We used this method last week to determine the problem in the 6m machine we have been bringing up was due to duplexer. It turned out to be a loose connection to the outside tuning tube passband cavity on the ground side. >From what I have learned in my brief introduction to being a repeater jockey is that ground/shield integrity is the first key to success. Evaluate the suggestions of others. I am a noob at this, and can only recount from my limited experience.

Looking for assistance w/ a new repeater system in GR, Michigan... Could use a hand in finding out why we can not pick-up 5watt handheld's only 5 miles out, maybe we missed something in setup? If anyone is knowledgable in troubleshooting repeaters or in the GR area, please contact me! Small business that can't quite afford the $70/hr charge for a tech right now lol. Thanks! Yahoo!
