I've run one of those as a repeater for about 25 years now. It saw service in a very active linked repeater network for the first 10 of those years. I've moved it down to the 420 range for a link, and now back up into the 440 repeater segment. The units will exhibit desense unless the driver and PA sections are tuned very carefully. After tuning, if the power control pot is adjusted, a touch-up of the driver/pa is required. You can also impact the performance by careful adjustment of the RX front end coils while the transmitter is keyed. I turned another one into a full duplex base station.
