John,
Your Holden QTH is with 1 Km of Worcester, which operates a smart grid (courtesy of National Grid). I suspect that's the reason for the denial.

Dex,
When we get back to Massachusetts full-time at the end of this month, I
will be doing some research. There's no substation really nearby, but
I'll do some driving around. I also plan to do a little camping in the
woods near the <1km lines to see what I can hear/see with an SDR and a
laptop. That'll be lighter than carrying the old Rycom meter around!
I don't intend to raise any questions with UTC right away. Need to get
better educated first.
John, W1TAG
