IRAN: U.S. satellite feeds to Iran jammed

There was a lot of talk about the jamming on this thread:

Iranian Alert: Cuba reportedly Jamming US Based Iranian broadcasters Uplink Signal Into Iran 7/8/03

[Constitution Day]

Thanks for the ping!! It's about time.

Gotta go to a meeting now but I will check back soon.

[Zavien Doombringer]

That was my suggestion monday!

[Zavien Doombringer]

Can't argue with that!

I have a Charleville, Corrige' An IX 1777 that produces plenty of smoke and fire :) (See my profile)

[Zavien Doombringer]

Oh sorry, I didn't realize - Welcome to FreeRepublic!

[Gary Boldwater]

With all the sophisticated surviellance satellites you'd think the jamming source could be pinpointed in a few hours.

[Darksheare]

The broadcast has been jammed somewhere on our side of the pond.
Iranian Ayatollah sympathisers in operation. (Read as: Terrorists.)

[Darksheare]

What was his problem?
*chuckle*
Whatever it was, it's taken care of now.

[Zavien Doombringer]

Was analogman a troll? His account has been banned or suspended.

[Ernest_at_the_Beach]

Cuba , a lonely Caribbean Island or South America, all possible locations!

What is International Law regarding disruption of Satellite Communications I wonder?

[Darksheare]

It is largely illegal, but as AlGore opined, there's no controlling legal authority.
(The UN, but it is no controlling legal authority.)

It'd be even more insulting if the jamming was coming from somewhere in the US.
Hope we find it soon.
And level it.

[Bobalu]

It is the uplink frequency that is being jammed
This uplink freq has to be jammed from a geographic
location very near the US... this is because the receiving
dish on the sat is spotted on the center of the US.

Cuba is near enough... but they would still be several DB down and so would need considerable wattage to block a US uplink to the sat... so they must be pouring it on bigtime.

The US knows exactly where the signal is coming from... to within yards!

I'm not sure how much uplink signal the bird can stand and remain stable... but I suggest uplinking the feeds from the US with a 100' dish with very narrow beamwidth and at least 100kw... this will up the ante considerably

of course to disrupt an uplink you only need to corrupt a tiny portion of the signal..so the cubans can pour everything they have into a very narrow bandwidth :-(

[Darksheare]

100kw might fry the bird's electronics package.
But it might work.
The so-called 'burn through' in jamming where the incoming signal overcomes your jamming efforts.
(Not that I know much about this stuff, but it's worth a shot to check into.)

If it's Cuber doin git, we can emp pulse their transmitter.. .and everything else they've got.
But that'll take some explaining.

[Bobalu]

Yup.. 100kw into a 100' dish w/narrow beamwidth would be mighty powerful at only 22,000 miles out...

especially considering that you can uplink a useable video feed to a modern satellite with only a handfull of watts into a tiny dish only a few feet across...

[Darksheare]

But it'd be H#ll to jam.
