I've been reporting on the Wobbler signal - the one that sounds
like wobbling sheet steel - most often heard by me on 930 and by
others on other BCB frequencies, generally 1100 and below.
As I shut down my receiver late last night I noticed something
strange about what is already strange. The Wobbler seems to come
in strong, even with the most minimal antenna. Where other signals
fade away as the antenna is reduced, the Wobbler really doesn't.
I've found I get it like gangbusters with a small whip. Even
a 6-inch piece of wire stuck in the center contact of the receiver coax
connector brought the Wobbler in. The S-meter is laying on the
right stop with RF gain full up, only slight background signals down in
the noise, and the Wobbler is wobbling away. The more I crack
up the active antenna gain, the more other signals come in, and the
less overpowering is the Wobbler, staying pretty much at the same level
it seems.
I've been listening to it like this all afternoon and evening so
far, and the signal never seems to fade. It isn't always there,
but when it is, it always seems to be at the same strength. The
violence of the wobbling rises and falls, but the loudness of the signal
does not, to any substantial degree. Nor is there any appreciable
difference between mid day reception and late night.
I admit I'm using some tuning tricks that enhance hearing the
Wobbler - USB, narrow filter, detuning, even DSP - but still, it does
not act like normal signals would, day or night.
To me, this argues against the notion of jamming. Especially
when you consider the only stations I hear during the day are Cuban, so
what is there to jam?
Just thought I'd report these latest observations, for those who
have an interest.
And as always, I welcome any thoughts, suggestions, or theories
anyone would care to offer.
