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)!
