Airtronics Vanguard doesn't transmit
Ihave a Vanguard 4 Channel Radio that Iwas trying to connect to an RD8000 to use as a buddy box. Seems something must have blown because now the Vanguard doesn't seem to work with the receiver any more. The power meter still shows a full battery but nothing on the plane. Any ideas? The switch on the Vanguard is much more comfortable to use than the button on the RD8000.
