QMX high band no receive

 

Hello,
Anyone out there do repairs on a QMX? I don't have the technical skills to do the work myself.
Radio was functioning as normal until I attempted the SSB beta firmware. After that, the digi receive was lower, and power output dropped from 5 watts to 1.5.
Turned the radio on today, saw signals on the FT8 waterfall for about a minute and then silence. Tried to listen to CW signals but nothing there. Tried other bands also.
Can anyone help?
Thanks,
Ryan KK5NM
 

Contact Jeff Moore W1NC. He has repaired many QMX and QMX + rigs. You will see many positive posts regarding his work.?

I'm not sure if it's a coincidence, but the receive Mux chips (IC402 and IC403 on the diagrams) on my unit also died when trying the new firmware.

Agreed that it would like Jeff is the right person to contact for repair.
