FWIW, overload from a strong local signal can cause much weaker signals to behave this way. Once amplifier stages in a receiver are driven into overload, they produce all sorts of mixing products with any signal coming through. The overloading signal may have been far off frequency, even on another Ham band, so it was not obvious to the operator.
