[ICOM] IC 706 MK II G

Does it come back to normal receive when you unkey?
It  MIGHT  be possible that you lose PLL lock.
 
My guess, though, is that your PA device might have
become temperature sensitive.

At first I was thinking heat issue but I did add an additional fan so don't think its the problem. Also it only effects 2M. I put the meter on "PO" so I can watch and track the power out. All will be fine and then I will lose the power out. Red transmit lite is on so rig is in transmit, just no power out. I also switched microphones and no change. Same with antenna/feedline. I used a spare mag mount antenna and still same issue. I also opened the rig and checked all the circuit board screws to ensure good contact.> > > > I would have thought finals, but the problem will exhibit itself for a few minutes and then all will be well for a while.> > > > Scratchin my head, hoping someone has ideas??????
