I had previously tried COM PTT and all the settings under that setting page. Ultimately I was able to get it working (with the COM PTT setting) yesterday with either a reboot of the computer or running updates on the computer. I ran updates and then rebooted and it started working. I read through many of the blogs and articles on the site and the Digirig seems very flexible. It would be helpful to start having some more radio specific documentation around. I had to wade through quite a number of articles and still ended up guessing on the settings.
For anyone that finds this in the future, here’s the setup that got me working:
Icom 2730A - Digirig ICOM cables plugged into Mic port and SP2 [Speaker output 2] (I chose SP2, so right freqency audio went to computer and left audio still comes out of the speaker on the radio)
Digirig - Digirig ICOM cable plugged into AUDIO port
VARA FM
- Audio tab settings - Both Microphone and speakers set to the Digirig USB audio
- PTT tab Settings - COM PTT - COM10 selected - RTS selected
