I have been using an Elecraft KPA-500 linear amplifier and a KAT-500 Antenna tuner with my Icom radios (mostly the IC-7600 and briefly with the IC-7300) After much research and discussion, I figured out what I thought was the best way to interconnect the IC-7600 with the KAT/KPA-500 so that the Amp would be protected...

I have had a number of automatic Antenna Tuners in recent years.I have had MFJ tuners, LDG tuners and the built-in tuners in my TS-930s, Elecraft K2, ICOM IC-7600, and Yaesu FTDX-3000. They have all worked pretty well. The first LDG tuner, the IT-1100 has been a real survivor. I put it in my mobile... Continue Reading →
