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

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.


First, I'm going to assume that there's a problem with the way the
file is encoded - if it's stretched out to 10 seconds (more or less)
then you can start getting a sense of what's going on.

Sounds like some sort of analog, time-multiplexed, instrumentation
signal to me.
