I just tuned into the BBC (it's just after 0300 UTC as I write this) and
both 5975 and 9525 are covered up by that noise again. The one that
sounds like it's flourescent light QRM. The one that suddenly appeared
just after Christmas, then disappeared just after New Years, but now is
back. Whoever is doing this is quite close, RF wise, to my Northern
California location; I hear the noise even when I have the radio in a
position that is usually a "dead spot". It totally wipes out the BBC's
signal. I'm SURE this isn't a mixing product or front end overloading;
it doesn't appear on the stations on either side of the BBC's channel.
Is anybody else hearing this? I know that Arnie and Mark Zenier heard it
last time, so I'm not going crazy. Tune in to the BBC on 5975 and 9525
around 0300, just to see if you hear it. I'd like to know if more
easterly DXers like Ace can hear this and what they make of it.

So, "tote your portable ;-)". Well, I mean that in the real sense of
taking a radio around your neighborhood and seeing if it's local or
outside the area. If you don't have a portable shortwave, see if you
can pick it up on the high end of the AM band. Back when I really
had a problem, I found that it was the neighbor's line doubled back
projection TV when somebody was playing with the game console. (That,
and a corroded antenna wire).

The stuff I get now sounds like one or more computer monitor or TV
horizontal scan circuits, so I expect that one of the neighbors is
leaving their TV on. Or got a new set or 'puter for Xmas. Since they
run on (sort of) standard frequencies, the interference can seem the
same all around the world, but comes from a multitude of local sources
instead of one very powerful distant one. (OTOH, if it's drifty,
suspect those damn compact fluorescent lamps).

9525 has been so variable lately. Last Friday was strong all evening
until signoff at 04:00, but other nights last week were just horrible.
Makes me wonder if the folks in Florida let their antenna fall in the
swamp over Xmas vacation.

Keep track of the signal strength. The interference may be there all
along but doesn't really have an impact unless the signals are down
around S2-3.
