> 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!
