+ AA6YQ comments below

I built two QDX' this week, and neither one will transmit in WSJTx. They appear to work fine in the telnet Transmit Test. Here is what I see:
WSJTx:
9 vdc
RX 117 Ma
TX 104 Ma (no output on dummy load)

Telnet Tx Test
9vdc
Rx 115 Ma
PTT 103 Ma
Tx 760 Ma and I get 3.75w on the dummy load

So, it appears WSJTx is keying the QDX, but not creating a signal. Any ideas as to what could be causing this?

+ What's a QDX?

+ On the Radio tab of the WSJT-X Settings window, to what is the Rig selector set?
