[Elecraft] Broadcast band interference [KX3}]

[David Christ]

Somewhere in the back of my head is a recollection of issues surrounding spurious signals caused by the mixing of strong signals in things like corroded gutter joints etc.  If there is a strong signal present from the AM station at all times then the other signal varying in strength might cause his fade in and out issue.

Can some who is a real engineer tell me if this makes sense or have I been smoking green leafy stuff?
