Actually from my experience this is probably good news. I've been told by
K3RFI (who does RFI investigations for a local power company, and has been
a great help), and confirmed through reading, that a noise source that is
not audible on lower frequencies is probably quite close, while ones that
are audible on 80m can be as much as a couple of miles away. So yours may
be very close by.
