I recently purchased a digirig and a Yaesu and Icom 9600 baud MiniDin6 audio cable. All is working fine except for one instance.
When I have the MiniDin6 connected to the digirig and then the usbc-to-usbc cable connected to the computer, I can use my radio as normal (not thru the computer). I listed and the press the PTT on the hand mic, release it when I’m done and all is good.
When I have the MiniDin6 connected to the digirig and then the usbc-to-usbc-cable is disconnected from the computer (using the usb-c port for something else at the moment) and I press PTT on the hand mic in the 2m range, the TX sticks on (indicated by the light on the radio), even after releasing the PTT button. When I press PTT in the 70cm range, all works fine (as expected).
It took me a while to narrow this done. I would be talking on various repeaters and sometimes all was working fine. Other times, it was only a problem on certain repeaters. I then tried it on simplex, just to rule out a repeater issue, and saw the same behavior in 2m and 70cm.
I know the answer could be “keep the digirig plugged into usb-c or unplug the MiniDin6 when you are not using it” but easier said then done.
Thoughts on this behavior?
