![]() While the duplexer is rated at 50 watts, these duplexers can and do fail, especially when used at maximum power. These duplexers are notch type duplexers, so on the TX side they are tuned to notch out (remove) the RX frequency and on the RX side they are tuned to notch out the TX frequency. At VHF 4.5 MHz is the minimum TX to RX separation and at UHF 5 MHz is the minimum TX to RX separation. These small duplexers are limited in TX to RX frequency separation.

However the repeater manual states ' Never reapply AC power to the repeater with a discharged battery connected, as the DC startup current can damage the repeater and battery '. If you have 50watts out of the transmitter into a dummy load or properly matched antenna then the problem is not in the transmitter. We have recently accuired a Vertex VXR-7000 repeater for 70 cm ham service and planned to hook it up to our site battery backup system (650 Ah with dedicated charger). Going on the assumption that this is a UHF repeater I would say that you have identified the problem, it lies with the duplexer which is very likely improperly tuned.
