Hi Ron,
To me it sounds more like a data signal. Note that it
sounds like it is "switching" from one state to another
over the duration of the audio clip. Let's hope it's not
caused by some common device that has been/will be
in use by the general public!
Can you hear the noise on an AM radio that can tune to
the "aircraft band", say around 130 mhz? (Try surveying
the neighborhood.) Perhaps a RFI tracking radio with
a Moxon antenna call help pinpoint the noise source.
73!
