I have a wave file from a radio reception made four decades ago.

ftp://www.members.aol.com/hdblenner/sound.wav

The sound is familiar to me and wonder how others would characterize
this signal?

I withhold my opinion of the sound to avoid biasing the views of
others.

TIA

Herbert


Microphone squelch? It's only 1/4 second long.
