When I lived near Chicago I heard a mixture of two AM broadcast on 80m using a 160' high rotating dipole. I assumed that something was rectifying but I never found the solution. I am curious if you are received this interference while using bandpass filters.

It peaks about S6 and is quite noticeable with only coax connected and no antenna selected. I have (2) -K3 and it is present on both. I installed new synth boards in one but the interference is still there. It sounds like a very broad FM signal. I had the station engineer do a spectrum search and he found no issues. I do not find this interference on an Icom radio. Has anyone else experienced this and if so have you found any solutions? I did a check of just the K3 (a year or so ago) on battery power and no other connections and it was still present although much weaker.
