Sounds like an AC line arc.
Sounds like some I have tracked down here locally, Eric.

My good friend Tm Shoppa, N3QE has run into a vexing RFI issue.
He posed the following on the PVRC reflector, but is not on the RFI
reflector.
Please feel free to respond directly to Tim.
Thanks & 73,
Eric W3DQ

Subject: [PVRC] Help me identify my new RFI
In the past week a brand new 24x7 noise source came out of nowhere.
Clearly audible all over my neighborhood under every power line 540kHz -
1710kHz.
Recording made on 1.8MHz with receiver in 2400Hz bandwidth AM:
http://n3qe.org/n3qe-rfi.wav
Heard in AM, this not simple 120Hz impulse noise but shows strong
800Hz-1200Hz audio component interrupted at 120Hz. Waveform picture of
the above audio sample shown below (not attached).
Any ideas?
Tim N3QE
