I am using packet (ax25) in build a pi for winlink on the Raspberry pi with a sound cart and a relay to let the ptt react on my HT (wouxun kg-uvd1).
Direwolf is responsible for giving a signal over gpio pin 26 to activate de ptt of the HT. This is working very well and reliable.
For the winlink vara-FM mode in build a pi, I want also to let it work on the same HT and a gpio pin of the raspberry pi.
When I look in the menu of Vara-FM? I can only chose for a comport and nothing like another external possibility.
Is there an option to use the vara-fm comport over a gpio pin of the raspberry pi?? So that I can use this signal to activate the relay which activates the ptt.?
I know I can use a digirig, but first I want to see if this is possible.
I hope someone can give me a tip if this is possible and how to do it.
