Hi all, I have a new 'sound' appearing on the band recently.....
I had something like that once - it turned out to be coming from a computer
printer that had a flashing tell-tale LED when in standby mode - it was
obvious the noise and the flashing were synchronised, and it went away when
the printer was unplugged. I once did some EMC measurements on PC SMPSUs
which generated more noise when they were on standby than when running at
full power - so it is worth looking for that kind of thing.
