#QDX My low band QDX works fine on all bands but will fail to tx on 20M #qdx


 

Hi all,
I have build a high band QDX witch Blown up dramatic and now my low band QDX works OK on RX but will crash if i TX on 20M.
It will TX on 80, 60, 40 and 30M without error but if a start TX on 20M it immediately crashes and looses connection on USB.
This happens with WSJTX but als with putty if testing TX on 20M.
I have checked and recheced all Capacitors and coils and even rewound 1 but no change yet.

I have a rev 5 board with latest firmware and reset to factory rest ones...

any idea would be appriciated.

Benno
