(Warning: Loud) What is this sound in the MW band?
Attempt at embedding video
Heard this sound at about 1200 kHz AM using an analog consumer radio in eastern Czech Republic. (Could be a superheterodyne mirror from another band, though.) What is this? I don’t have an SDR or other ham equipment, this is just a mic recording.
I thought it could be useful to drive mice out of a garden shack but it was gone the next day.
