Is somebody jamming the BBC?
 

For the last three early mornings (world day) I've heard a strange noise
on the frequencies used by the BBC at 0300 (5975 and 9525), sort of like
the hum of a flourescent light fixture or some other electronic QRM.
Finally I got curious and tuned to either side of the 5975 freq, and
Radio Habana Cuba on 6000 and Radio Japan in Japanese from Sackville on
5960 come in almost crystal clear, so it's not spectrumwide QRM but just
confined to the frequencies used by the BBC. I know that this started
Thursday December 30 around 0308 (late Wednesday evening here in the US)
because I was listening to the BBC on 5975 when it came on and the BBC
was clear before this but this noise wiped out audibility completely.
Has anybody else heard this? I'm using a Degen 1102 with the factory
longwire antenna (the one that plugs into the jack) oriented
approximately E-W.

It'll be one of Terry Wogan's snorkers fell down amongst the gubbins.

I think that for the most part it's the selectivity of your radio. But, you
might wish to experiment with the orientation of your antenna.

I agree Steve. In my experience, ant orientation has cured most of my
problems.

Same problem here (Seattle). Sounds like computer monitors. Signal
strength is way down on both those frequencies so the QRM may have been
there all along. I blame the space weather and the time of the year,
as 6135 is down in the mud, too.

I've heard it too and this is new, now 4-5 days running. I'm likely a long
way from you at 52N, 102W, with an unchanged set up re antennas and radio.
Someone is pulling up noise. I did see some northern lights starting 30
Dec approx 5 pm local, (-6 UTC), but none since.

5975 and 9525 are clear as of 0200 January 3. You're WAY north and east
of me, Arnie, and somebody in Seattle reported the same thing, so it
wasn't local to me. But if it was an attempt to jam, it's gone for now.
