Start by reading this: http://www.repeater-builder.com/rbtip/effectivesens.html What you want to do is first test the repeater for desense with the transmitter operating into a 50 ohm load. The receiver should have the same sensitivity through the iso-T with the transmitter off or on. If not, you have an issue with your duplexer. Once you have the station operating properly into a load, then begin the test at the site. You are looking for two issues. 1. Is the receiver being desensed by site noise? 2. Does the repeater operate without desense [or without any more desense than observed in step 1] when the repeater transmitter is active and the system is using its antenna. Yahoo!
