No RF Out on Low or Classic RF Boards

[n4rg]

I have been running the (tr)uSDX for a while without any problems. Then tonight I was running JS8CALL and I notice the display got really dim (I am running on 12VDC battery), so I was thinking that the batteries were getting low. Swapped them out. Display was still very dim....it slowly go brighter and brighter until it was back to normal. I have a second rig off to the side that I use (without an antenna hooked up) to listen to my transmitted signal (to verify proper Audio USB driver selection) and didn;t here anything at all.
Then I notice when I put the (tr)uSDX radio in CW mode, and pressed the PTT, i was showing 0.00 watts out and VSWR of 1.0 (and then bounces around). I swapped out the classic board with the Low board (thinking that I had blown the finals), and of course changed the PA bias from 160 to the 128 and Classic to Low on the menues, still no RF out.....I reflashed the radio and that didn't help either.

Suggestions????? Obviously it must be in the Digital board, right?

Thanks,

Herb
