Left Flex-6500 and computer running for a few hours this afternoon unattended. When I returned and tried to transmit USB on 15 meters, I had no output. I verified that that RF output slider was moved up to put out power and that MIC was selected. When I hit MOX button and spoke into microphone, I get no modulation or watts output. If I hit tune button, it shows 15 watts out along with SWR. It I turm amp on and hit Tune, it shows about 150 watts out. Problem seems to be no modulation on SSB when I speak into mike, CW seems to be working fine. I have tried several cold boots of computer and Flex-6500 to no avail.

Any suggestions?
