vigilant TV

NBC has a piece on private satellite broadcasts to Iran being jammed by a source in Cuba. The broadcasts are made by private TV studios, mostly low budget Iranian language news and chat shows. Iran had been largely unsuccessful at jamming the broadcasts from within the country, as we reported last month.

One of the sources said that [Telstar-12 operators Loral Skynet], working with transmitter location expert TLS Inc. of Chantilly, Va., had further fixed the location as “20 miles outside of Havana.” Cuba’s main electronic eavesdropping base, at Bejucal, is about 20 miles outside of the Cuban capital. The base, built for Cuba by the Russians in the early 1990’s, monitors and intercepts satellite communications.

The Farsi language broadcasts, by the Los Angeles-based ParsTV, Azadi Television and Appadana TV, are uplinked in the US via Telstar-5, which is over the United States. They are then turned around at the Washington International Teleport in Alexandria, Va., where they are joined by the VOA broadcast and uplinked again to Telstar-12 over the eastern Atlantic Ocean.

       It is the Telstar-12 uplink that is being jammed, say investigators for companies working with the broadcasters, cutting off broadcasts not only in Iran but in Europe and the rest of the Middle East as well. The jamming could emanate from anywhere within the satellite’s uplink footprint, which covers all the Eastern United States, the Caribbean and South America, say investigators. In the past, the Iranian government, using high-power transmitters on towers in cities such as Tehran have been able to jam it locally. The fact that TV viewers elsewhere can’t see it was the first hint that the jamming was happening on this side of the Atlantic. – NBC, U.S. satellite feeds to Iran jammed: Jamming signals are coming from Cuba, sources say.
