A defective FM filter for the K3 can be 1) Well off frequency and a loud station well into normal limiting will "fill" the filter's skewed bandwidth, and present a badly distorted signal to the following IF. 2) can have defective internal crystal mounts, or defective crystals. Being non-linear, these have been known to generate IMD all by themselves.
3) Not defective, but somehow the offset for the filter has been set to some wild value, and that part of K3 setup utility needs redoing. Call the support staff and get help. 73, Guy.
