[Elecraft] My KAT500 won't tune when RF is applied via keying down on the microphone or by using the CW paddle. It tunes if I whistle into the microphone. I have it set up as Figure 5. General Cabling Requirements - Stand-Alone Transmitter or Transceiver shows in the manual. I have an Yaesu 450D. Any suggestions as to what the problem is?
