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?

Jim,

When you simply press the mic PTT, there is very little power out in SSB
mode until you talk into the mic - the SSB carrier is suppressed, and
all you are transmitting is the suppressed carrier until you produce
audio into the microphone.
The KAT500 needs at least 7 watts to tune.

For CW, do you get power output when you close the key? The FT-450 must
be put into Break-In state to deliver RF on a key closure. I suppose
there may be the possibility of holding PTT closed and then keying the
FT-450 without being in Break-In mode, but I have not studied the entire
FT-450 manual.
