I guess I should have emphasized that the RF interference this generated was discrete frequencies; as I recall it was at abt 3517, extending below that frequency for about 20 khz at diminishing strength, and 3795 in the same pattern.  As I was trying to wrap up my 80M DXCC at that time, you can imagine it was a problem.  It really seems as if some sort of active device, perhap[s combined with the radiation mechanism Jim describes, would have been needed in order to cause what I heard.  I doubt I corrected a wiring error at the switch; most likely I just replaced the switch with the wires in the same positions as originally.
