Has anyone experienced any RF distortion in their audio while operating with their TS 2000? Mine seems to be prone to RF in the audio, especially on 75 meters. I have operated many radios (IC-746, IC706 ,TS950SD ,TS-570, FT1000MP) with the same confiuration of antennas and location of radio, this is the only radio that gives me a problem, Thanks in advance Bill, WR2M
