Wrong in command stream

Hello there,

New VarAC user but have been operating VARA from the beginning.

Using FT-991A. Rig sync ok, it switches to the right frequency and to the right mode. (D-U).

The PTT test in VarAC is ok and the tune button in VARA switches the TX on.

When I try to call CQ nothing happens. In the command stream appears "wrong" and TX is not activated.

Any clues why ? Thanks - Ezio - K3EK
