Default Re: Sony ICF-SW1 'overloading' on FM?

A thought: I wonder if the IF 10.7 Mc/s filter system is working properly? You mention splatter from strong-signal transmitters not too far removed in frequency. A failure in IF selectivity - especially on the outer IF response frequency skirts - can give this problem. The IF filter could be ordinary LC transformers or it could be a ceramic filter. I certainly have had problems in the past with such ceramic filters (or their driving circuitry) failing.
