I agree fully with Guy. Most problems of that nature are an antenna problem. If you have an antenna analyzer, connect it to the PL-259 that you normally connect to the K3 - do not add or subtract any coax. Then read the impedance (R and jX, not just SWR). If it is extremely high or extremely low, that is your problem. The fact that one tuner used to match it says nothing about another tuner's capability, nor how the antenna is behaving at this point in time.
