because you are close to the transmitter and are hearing the 3rd harmonic of the broadcast station.
Yup, and it's possible that third harmonic is being generated right in the receiver front end especially if the noise blanker is enabled.
Some AM stations are poorly maintained because all the money goes into FM HD and subchannels.
I could hear the third harmonic of a 5 kW station on 1270 khz, very well, S5, on 80 m, 5 miles away.
