I got hold of a couple of Corcom 3 phase 200A filters and have been
thinking about running one single phase. IIRC that would require
derating to 100A, plenty for my service, and as long as the meter
doesn't read reactive current...

How crazy of an idea is it to put toroids on the incoming service AC
lines?
Having done considerable research on the use of ferrite chokes to
suppress RFI noise, it's one of the LAST things I would bother to do,
except under very unusual circumstances. When I lived in Chicago, the
AC line was an twisted triplet (120-0-120) with bare neutral, about 80
ft long, that ran about 20 ft below my wire dipoles, and more or less
in parallel. I put about six 2-inch long, 1-inch i.d. #31 clamp-ons
on that feeder, hoping that it might minimize the common mode trash
coming radiating from that section of the power system.It have helped
by a dB or two on some bands, but I was never convinced that it did
anything useful.
