3 Royalty-Free Audio Tracks for "Longwave"

A recording of an old radio tuned into static on he longwave band.

Rapid beeping, captured on an old tube radio with a long antenna. Recorded with a tascam dr-40x.

I foudd this frequency, between 4450 and 4475 khz whilst going through channels on radiosdr. Org. It sounds a bit like a printer and then lower down sounds like a laser. Sorry for the sound of me pressing the keyboard, my laptop has an internal microphone so this was picked up.
