In SSB mode, until you speak into the mike, there is no output signal in
transmit mode. Switch to CW mode, key the radio via an external key or
paddle and see what you have. Or press XMIT/TUNE function for 2
seconds. You should have output. Also check to see what value of PWR
is set on the radio. I use 20 watts for TUNE for all bands when the
KPA500 is in OPER mode.
