I had a very similar thing on rigs in my shack. The trouble in my case was
that the mechanical connections of my guy wires to my tower were not bonded.
Apparently the oxidation in the joints served to create harmonics and thus
third and fifth order intermod products of two or more local AM broadcast
stations. Probably not your trouble, but might give you an avenue to
follow.

Subject: [TenTec] Century 21 Analog Question...
Hello:
I have an old Century 21 (analog dial) which seems to be suffering from
overload
on 40 meters; some SWBC station (apparently a domestic English language
religious station) is very clearly heard as you tune across the entire 40
meter band... with the CW and SSB signals also appearing as you happen
across them.
The rig appears to operate fine (with no SWBC blasting through) on 15
meters; I was astonished to work an F6 near Limoges on the first call...
Any comments, on list or e-mail, would certainly be appreciated.
73,
