chaotic spark interference on am radio

[51HHMD]

So basically AM radio amplifies electronically made sounds?

Amishman35; so when they sent telegraphs, they used AM radio?

To pick up a simple electric object interference, the frequency I use is below AM 160 between 140 and 161 AM. You can pick up things like a car going down the street or hear metal object interference like keys or a spoon.

Last night I was recording LF/VLF with my BT878 tuner Analog to Digital converter and found out that if you tune to 45 kilohertz or so, it is possible to tell when the light was on in the kitchen all the way down the other end of the house. So I recorded at 176400 hertz sample rate and sent the letters LQ (.-.. --.-) in morse code by flashing the light on and off. Sure enough, on the spectrum at 45 kilohertz, there was a broad emission of the morse letters LQ.
