1. Make sure that TxID is turned off.? Its timing is incompatible with QMX current tone detection, and QMX will drop tx in the pause between the TxID and normal modem signal (happens in many fldigi modes, not just RTTY) - probably a QMX firmware bug, it is on Hans list to fix.
2. In fldigi "Config - Modem - TTY - Tx" turn off "Shaped Tx".? This conflicts with QMX's own shaping algorithm, and causes it to drop transmit.
I hope that helps...
