[Lowfer] 1750M?

[WB9UWA Jim Shaffer]

Hi All,

I tracked down a PLC signal that turned out to be over a mile away. It can
be heard all over town
for a few miles in all directions. It would throw snowballs on QRSS10. Now
at QRSS30 or QRSS60
it is hardly noticable. The line passes just 1/4 mile North of me, but is
not generally well confined to
the lines. I think I would have issue with this source of interferance if I
were a licsensed user of 1750M.
In the absence of static, it is the dominate source of interferance here.
Seems be pretty broad (10khz) and
changes to a new set of frequencies about once each second. Quite musical.

73, Jim Shaffer, WB9UWA.
