Here is another video with AGC at 0dB and volume at 1px. XDKHEBM0khE And here is complaint about the same thing (he's reviewing the original fw, though).

BTW, looking at this code, some platforms allow up to 16 gain steps, wouldn'...

I recently flashed the latest stable version of OpenGD77 onto my Baofeng DM-1701. The amount of work put into this fi...
