Discovered this signal while modifying a GE superradio type countertop radio.

This was being picked up by the audio stage of a GE 7-4115B.
The RF stage AF output was grounded, so i know it didn't originate from there. It was connected to an MP3 player via 6ft RCA to phono cable. Seems to have been picked up solely by the audio amplifier of the radio.....
No direct capture of the audio, unfortunately.
Was Captured in Laramie county, WY, early 2022.

Spread-spectrum clock signal. They often sound like random tone chirps, just like this. It's probably from a nearby piece of computer equipment or even from the MP3 player you're using as an audio source.

Is that a microwave?

I mean it says radio in the tittle, if you mean the video....
If you mean the signal, then beats the heck out of me, lol

My guess is noise from a switched mode power supply.
