On the Flex 6500
loaded up smartSDR for first time today .. receiver works apparently, but no output on transmit into dummy load. tuner works and indicates success, but speaking into mic indicates 20 watts and no more , even on AM
In Tune mode, can you move the power to the right and see full power?
How about CW? What microphone are you using? In many cases, the +20db button needs to be pressed for full output - is the modulation meter fully deflecting?
By the way, I believe AM operation is not recommended at this time.
