Hello Ron,
I listened to the .wav files.
It sounds to me like a switching power supply and it's
associated electronics components. So many possibilities
but I've heard something simular to that. It was a
swimming pool owner who had an electronic device that used
pulses of DC current to break down rock salt into clorine.
Since he can get a general location of the source he needs
to expand his searce with the portable shortwave receiver.
Start walking into the 240 degree direction listening.
These types of problems don't travel very far so it maybe
closer than he might imagine but beyond his immediate
front yard.
Would be interested in his findings.
73,
Randy
