    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.

    It is not the microphone gain that probably needs to be adjusted. Instead, the deviation needs to be increased. There is a big difference between the two.

    You need to program the transmitter for "wide band" and not "narrow band". That will increase the deviation to +/- 5 kHz instead of +/- 2.5 kHz.

    Hello guy's, quick question about the anytone 778 where computer programming is concerned. There doesn't seem to be a prolific driver for this radio to computer program this radio. I've searched "Miklor" with no luck. Is there a prolific driver from another radio that will work. Thanks for the help and direction.

    I program Retevis radios for work (you can't beat $10 a pop for a radio that will get destroyed anyway). The driver that came with the cheapo Retevis radios work just fine with my AT-D878UV.

    Hello, can anybody say, which option in menu is related to mic gain please? If there is any.

    See reply #2, and there is no mic gain that I coud find.

    I tried this suggestion, it did not completely fix the problem but it did help out a lot and it is the best fix I have found

    Had the exactly the same problem on mine.
    Thanks Glen - as your suggestion helped.
    I also upped the TX power (where feasible) to increase SNR.
    Last option available is to crack the mic open and either increase the mic hole aperture or see if there's any adjustable electronics inside.
