The OpenG77 Option is to select the OpenGD77 as the "Radio/Modem Type:"
That setting has nothing to do with which HT you are talking into.
Just set that option back to whatever you had it set to before you changed it.
Also. You would be better off posting to the PiStar forum https://forum.pistar.uk/
PiStar is a completely different project, with no association with the OpenGD77 firmware, apart from allowing you to select the OpenGD77 as the Modem, in exactly the same way as the modem selection of "Icon Repeater Controller..." in PiStar has now affiliation with Icom
