Present setup is K2/100, KAT100, KPA500, and resonant antennas on 75 and 40 meters. Very rarely do SSB on any other bands. Stations seem to have trouble describing the problem. Reports vary from fuzziness, distortion, to clipping. I bypassed the tuner and amp, hooking feed line directly to K2/100 and also turned the power down to ten watts to shut off the KPA100 and problem persists. No difference between MH2 and CM500 mics. These test were done with stations who know my rig and my voice. This is an early K2/100. All mods were done years ago to K2, SSB, and KPA100. Receive audio is unchanged. Visual inspection of boards look OK. As a further check, I connected my KX3 to amp and antennas with great results. Any suggestions?
