[RFI] 80m whooper

[Pete Smith]

Can anyone help me identify the noise recording at 
www.pvrc.org/n4zr/80mwhooper.mp3?  It is apparently local or groundwave, to 
my north, and is audible at multiple frequencies across 80m, with various 
strengths - last night it had a different warbling pattern than today, and 
a friend can't hear it on skywave, which makes me hope it is VERY close.
