Hi, The distorted audio moves with the Control board, so either K2 can enjoy distorted transmit audio, if it has the faulty board fitted!
Just to clarify point 3. The 12v rail seemed to modulate on both K2's when using either the faulty ** OR ** the working Control board! As this effect is the same for both K2's with either Control board. This would seem to indicate it is some other measurement (etc) effect, that we are seeing? Thanks again!!! Regards Nicolas Original posting. Hi, Following reports of poor transmitted audio, and aided by a fellow K2 owner we set about a little investigation. What happens.. Raspy, clipping?, (distorted by RF?), almost Dalek (For UK readers!!), sounding transmit audio. We checked the various board, joints etc, swapped things with the known working K2 and established.. 1. The issue is with the control board, when swapped, it gives the same fault in either K2. 2. No obvious component problems. 3. Another interesting observation on both K2's, was how the 12v rail modulates when you transmit? Any suggestions, where / what to look for on the control board, or other ideas? Thanks!!!
