Thanks to all that replied. Some interesting thoughts to consider.
Just found the links -- didn't scroll down long enough before. :)
As K8CN noted, it looks like the source is switching on for 10 seconds
and turning back off. Is there any sort of pattern about times when the
noise appears? Always the same length of time its on? Could keeping
track of those times provide a clue? Perhaps to the neighbor?
How broad is the noise in frequency? Can you do a much wider waterfall
to get an idea of bandwidth?
I don't have a clue about possible sources, except that it doesn't look
like a power control device.
