Folks, are there communication bands around 1.17 MHz ?
I'm picking up interference at that frequency. The envelope looks to my eye like AM modulation.
If it matters, I'm on the landing path of an airport. Boeing 737s fly overhead with landing gear down.

@NickAlexeev In North America, that frequency is in the AM broadcast band. 540 kHz to about 1.7 MHz. Stations are spaced every 10 kHz.
