Hi all! I ended up splurging on this doohickey -
https://mfjenterprises.com/products/mfj-5008 . It's an ultra-sonic receiver
that purports "to pick up the noise generated by the corona discharge and
arcing connections". For those who may not be following my saga, I
determined using a portable SDR radio that the same noise that obliterates
40m up through 10m comes strongest from one of two electric poles near my
house. No other poles exhibit the noise. Using the MFJ-5008, I immediately
heard a very strong ringing from one of the two poles, which doesn't show
up when I point it at other poles, houses, etc. There's a little sight hole
you can use to pinpoint the noise, which I did - it seems near the top of
the pole is where the sound is loudest. Very easy to use, and seemed to
work as advertised. Totally understand why this is expensive, it's a very
niche item. I'll need to find a lot of RFI to make up the price tag, but
additional evidence helps!
I called the power company, who initially said they'd have a crew out in 4
hours. After days with no visit, and numerous calls to PSEG, they have no
information to provide. I filed a complaint with the NJ Board of Public
Utilities asking that they follow up with PSEG and compel them to consider
my complaint. If anyone has a contact with PSEG, I'd really appreciate a
connection off list.
If folks are interested, I'll try to make a little video of using the
device. Also, if you're in the Southern NJ area and need to borrow it, I
accept beer! :)
Thanks again for the help and moral support!
