I'm having trouble getting a viagra b board installed in a dx959. The board seems to work fine in AM and. USB but is having a problem on LSB. The freq is on for USB (27.205 MHz at antenna and 15.3625 MHz at TP5 on ch20 ). But on LSB it is messed up (27.210 at antenna and still 15.3625 (instead of 15.3575) at TP5). Anyone got a possible cause other than bad pll on the viagra board?
