SPE Expert 1KFA ham radio amplifier with automatic antenna tuner built in. Often I wished my Heathkit SA-2040 Antenna Tuner had a bypass capability so that I could check the real SWR on my antenna or listen to a band other than the one the tuner is adjusted for without the reduced receiver sensitivity. I was looking at an SPE Expert amplifier and I see it has an internal antenna tuner which can handle SWR's of up to 4:0.
