Subject: [YaesuFT847] FT-847 only transmitting on FM mode. de: W1SMS

?

To the group;
My trusty FT-847 has stopped transmitting on all bands (HF>UHF) on SSB, CW and AM modes. It does work OK on the FM mode - TX audio via mic is OK.
I did try swapping the TX & RX filter modules with no change.
I also reset the uP using menu #39 without any success.
Any suggestions on where to start troubleshooting?
Thanks and 73,
Steve W1SMS?
