When I lived near Chicago I heard a mixture of two AM broadcast on 80m using a 160' high rotating dipole.
I first experienced this in 1953 (before I was licensed) with stations near me on 930 kHz and 1470 kHz mixed on 3870 (I think). This is nothing more than passive intermod, and can occur virtually anywhere, including in one of the transmitters! I also experienced it intermittently when I lived on the northside of Chicago three miles N of Wrigley Field, and the mixes were of 50kW stations with TX locations 20 miles W of me. I even heard WBBM's second harmonic (on 1560 kHz)!
