In fact, I am building a web site with known SDR gathered signatures of
RFI. So... If you know the source, for sure, please send me a snapshot
from your SDR. I will have a page up by months end with RFI snapshots
and what caused it.

I have successfully found about a dozen street lamps which had failing
sodium vapor lamps causing RFI.
The spectrum of the RFI was primarily located between about 5 MHz to an
upper limit of 8 MHz.
Great info, Karin. The next time this happens, can you grab some RF
spectrum plots with waterfalls? I've found that these signatures can
be quite helpful in providing clues about possible sources. The
availability of low cost SDRs makes this easy.
