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.
