No SSB power output from 6400

K1DJB · March 10

I am not getting any power output when transmitting on SSB USB/LSB on any bands. I hear the radio click and the power button turns red, but no output. When I set my tune to 100W, it transmits fine at 100W (and tunes OK).

When I switch to FT8 it works as expected and I can complete contacts. I also get output power on AM and FM (but nothing on CW...but I don't have a key...not sure if that matters).

I have tried this on my Mac SmartSDR and my PC, same experience. I just upgraded to v3.8.23 on my PC and am experiencing the same issues.

I have an external meter, and that is not showing any power on SSB either (but does match the SmartSDR output meter for the most part).

Receive is working fine on all bands. Any ideas?

Hmmmm…. when you attempt to transmit on SSB, do you see any indication on the Mic Level indicator or the Compression indicator?

SSB only outputs RF when there is an audio signal 'pushing' it (Unlike the other modes you've mentioned'), so I'm wondering if there is a problem with the mike or mic settings?

Well...chalk this one up to operator/newbie error. Thank you Don, I played around with the MIC settings and it is working fine. Doh!
