Sounds like your antenna has been isolated from your receiver. Check or replace the cable between the receiver and the duplexer. If that doesn't fix the problem, you may have a mis-tuned duplexer or a blown pre-amp if you are using one. RF issues are the same in digital as they are in analog. An experienced repeater owner in your area might spot the problem quickly. Ernie W6KAP
