Have a few Galaxys with the same problem the driver bias is too low like 35 ma max can't get the 50 to 75 they want .2 of the radios are galaxy 99v's and 1 dx88hl they all work great but vr11 is maxed and only reads 35 ma the final vr10 and vr 20 I can get set correctly on all 3 but the driver bias is low on the 2166 drivers.The radios seem to work fine but would like to fix it correctly.Any help is appreciated Jef
