[IRCA] 1100 Wobbler

["W. Curt Deegan" <WWWR@xxxxxxxxxxxxx>]

I've been away from my PC this evening, and only just read through all of 
the Wobbler postings.  I'm glad to see a lot of people are getting a chance 
to hear this thing.  I admit to being surprised how well it is getting out, 
considering the presumed underlying station is no powerhouse.

To give what few answers I have:

The 1100 Wobbler is on a moderately powered station, from all 
indications.  During the day I have been able to hear the 1100 Wobbler, but 
only just barely.  Without the Wobbler I would be unable to hear anything 
at all from that station.  West coast Florida DXers can hear the station 
during the day better than me because it is located near Havana on the 
western coast of Cuba.  But even they did not notice it had returned to the 
air until I reported hearing a Wobbler on the frequency -- a certain clue 
of a Cuba station.  At night without the Wobbler the station could be 
audible to me but unremarkable.  The affect of the wildly swinging carrier 
when propagated by sky wave is amazing, something I have been harping on 
for some time now.

Here in Florida at night, the Wobbler when it is this extreme is 
overpowering on the frequency.  When it stops -- rarely as that is the last 
three days -- I have a jumble of fading in and out stations, nothing, 
including Cadena Habana -- the presumed source of this Wobbler -- is 
especially dominant.

As Craig Healy explained in a post, the seeming different wobble rates in 
different modes is because the wobbling is of the carrier itself and shows 
up doubly in AM (or DSB) on both sides of the carrier vs SB mode, where 
you're only hearing half the wobble.

There are audio samples and spectrum scans of the signal as heard here in 
Florida, on the Wobbler web site.

There is a lot more than I can describe here -- or would presume to do in 
consideration of everyone's time.  If you want to know all the gory 
details, see my Wobbler web site at the link in my signature below.  Be 
aware though, there are no definite answers, only conjecture.  When it 
comes to Cuba, that's about the best you can get.
