Good afternoon Laurence
The DTX 1 boots up normally and then the top button is pressed the middle LED comes on and the device is in transmit . As part of a considered upgrade to the GB3UD transmit line up this is a minor issue and can be overcome by external means.
However the existing exciter works in a similar fashion but automatically goes to transmit after boot up , this is a useful asset as in the case of a mains failure the transmitter comes strait on, just after power is restored. Therefore I wondered if a small change in the software can easily be introduced to get the DTX1 to go automatically to transmit after power restoration instead of having to make a bit of external circuitry to achieve just this action.
No rush for a reply kind regards Albert G4DHO
