I recently received an AnyTone AT-778UV as a gift. The radio works ok, and it is easy to program. One issue I have had with it is mic gain. Everyone I talk to on repeaters or simplex tells me that my signal is strong but I need to bump the mic gain up. This seems to be the only thing that I can't find to adjust. I have tried to contact AnyTone via email and phone but I have not had any luck so far. So if anyone knows how to adjust the mic gain or to help solve the issue please let me know.
