Re: [IRCA] [NRC-AM] Wobbler Xtreme on 910

[Charles A & Leonor L Taylor <calltaylor@xxxxxxx>]

Curt,
 
I keep turning over scenarios in my mind to explain the Wobbler. Don't 
think it's a jammer because it's poor way to go about jamming, without 5 
paragraphs and a sentence to define a jammer and the best method(s) of 
jamming.

Think it's more likely a spur. That's been postulated before. Reason is 
it appears also to be positioned to jam (unintentionally) co-channel Cubans.
And it's not likely radiated by the co-channel Cuban.

I'm thinking some sort of artifact of a part of a downlink of a 
satellite signal. One in which a satellite receiver receives the beacon 
signal and heterodynes it down and
generates an unwanted 910 or 930 kHz product in the frequency conversion 
process. Even though the satellite beacon is stable at microwave 
frequencies, it still has minor phase/frequency instabilities that if 
measured directly look like fairly large excursions but which are still 
minor as a PERCENTAGE of the beacon frequency but large as a percentage 
of the artifact product. Instabilities of the satellite axis factored 
into doppler shift. The satellite wobbles to some extent. Or the 
radiating antenna shakes. Or something.

Are any brains really into gear in trying to analyze this Wobbler?

Does anyone have any experiences that could explain it?

Castro's Fairy Godfather isn't doing it.

Charlie
