Need help. FT8 decodes fine on 6600M , get tones through radio speaker on transmit but no output power.  Have read through the help suggestions, but have been unable to solve the problem.  Everything working fine on other modes including RTTY with N1MM.

You didn't say so I'll ask - does that radio switch into the transmit mode (is the PTT working)?

If so I might suggest checking to see if you have some narrow values in the high and low cuts in the microphone panel. I had this bite me a time or two while experimenting. Open the cuts up (like from 50 to 3000 Hz). While trying to get things set up for RTTY I had this happen and it took me a few minutes to figure out I had the cuts set to one place and the tones were somewhere else. Everything looked like it was working but there was no RF output.

Good luck
