i just traded a 2950 DX for a 200 GTLDX board PFM-0090A-BF and the radio works fine on LSB and USB, but TX only on high, no low power at all no AM or FM on any mode, is there some kind of modifiction to fix this? the reason why im asking is because i took the radio to a local CB shop, i explained the problem and after a week i got the radio back and it was still doing the same thing but was transmitting only on AM on only high power so i took it back and asked him to return it to its previous state, so does anyone know anything about this issue?
