One problem that cropped up after our 443.9 Repeater Upgrade was a decrease in receiver sensitivity. Stations that could once hit the repeater suddenly could not. Transmit power was reduced which we expected to cause some issues, but in fact it was receiver performance that was the problem.
We think this had to do with the use of a RG316 jumper and too many barrell couplers on the receive side, combined with operating in a high RF noise environment.
Both Rx and Tx jumpers were replaced today, and couplers reduced to one per jumper. Initial reports are of much improved receiver performance.
