Hello OM, you might try using 2m and a multielement hand held yagi to
further pin point the source. The receiver needs to be on SSB as you probably
already know.
You can further refine the technique by using a pair of yagis, fed out of
phase to look for a null in the noise instead of a peak. The null would be
quite sharp compared to a peak, which could be 50 or more degrees at the
-3dB points, depending on the size of the yagi used.
Happy hunting!

I am trying to precisely locate a strong static source, were familiar
with High tension lines arcing at the insulators on very dry days. this
however is the opposite , it only occurs when its raining or has been raining and
still wet out it is local . its only about 1000 Ft away but when I aim in
the general direction there is a good S9 static, popping sometimes
sounds like oil burning in a frying pan or a motor boat its constant for the
most part and particularly most strong on the 6,10,12,15M bands. With a
portable radio I have narrowed it down to 100 Ft radius in area near the
center of 2 streets, There is transformers, caps and splices in some the
power lines in the area but have yet to find the exact location of. power
line crews have looked in the past without finding anything but this has
been going on for 10+ years any ideas on exactly what might be the culprit?
again once its no longer raining or wet out it
completely goes away making it more difficult to find.
