I have 2 radios, one is a uniden ax144 and the other is a pearce simpson super cheetah. Both have almost identical chassis and both have the same fault. In tx or rx mode you can receive or transmit approx 10 channels either side of any selected frequency. The signals are at a much lower level, but are clean and clear. They seem to be equally spaced at 10kc...have used a receiver with vfo to check this. Other than this fault the radios work fine. I have spoken to several techs locally and been told to throw them in the bin. Has anyone ever come across a similar fault? Any ideas?
