This may not have made it through the first time.

--------------------------------------------

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
