Kenwood TR-7950. I had one plugged straight into a Yagi @ 5700 ft. for many years & never one burst of IMD. RX was sensitive enough to outperform a co-located 440 RX with GaAsFET preamp (foliage absorption was the likely reason for the difference in performance). The RFPA is able to handle continuous duty but does need a fan. There are also pots on the RFPA board that can get dirty & can cause the output to drop & go spurious. Bob NO6B
