W0AYE-10 is on as I type this. That's the gateway call sign.
Your VARA FM program running alone can do the setup.
Under settings / soundcard / autotune with W0AYE-10 to have it auto set the transmit levels.
If it's not transmitting check the PTT setting? under "settings". Default is VOX - you want serial.
You may need the driver from here?
to make the PTT active it the device manager shows no driver for that USB serial device
Also there's a "ping" via no body (because you are direct) to W0AYE-10
Good luck, it's worth it.
