However, the jamming was inadequate in the country side. To extend
the jamming range, Castro's engineers and pilots equipped several
Russian made Mi-17 helicopters with jamming equipment. The Cubans got
so exited that they even started jamming Radio Marti's services from
VOA transmitters in Greenville, NC, and Bethany, OH.
Radio Marti previous to this had not been jammed by Cubans for 5 years.
It has been recently reported in 1997 that "Med TV, the world's only
Kurdish language satellite TV, suffered deliberate technical interference
on 1st July, the launch date for its new test transmission on Eutelsat"
(Med TV/World Media, BBC). Before this there was a Turkish protest
aimed at Syria over Med TV's terrestrial relays. According to World
Media, the jamming was not an accident because "it completely swamped
Med TV with a noisy dark screen and silenced the TV sound."
The management of Eutelsat began to investigate this affair but
technically it is very difficult to determine the jammer's location.
Med TV director Hikmet Tabak's view is that the Turkish Government
has "both the political motive and the financial and technical
capacity" to jam the Kurdish television station. BBC monitoring
specialists confirm the existence of intentional jamming.
Med TV's representatives assert that interference in Turkey is
carried out from the Sinop uplink station "by means of military
equipment". It is difficult to counter this type of jamming
because the satellite's transponder automatically relays the jamming
signal sent to it.
In the fall of 1997 Anatoly Batiushkin, one of the former managers of
the Soviet jamming system, gave this answer to my inquiry: "All
employees who have had at one time a direct relationship with
(jamming) work are now retired pensioners, and my efforts to ask them to
review your book (Jamming) were not successful. All jamming sites have
been either converted to other purposes or have had their equipment
written off. All related legal, technical and operational documentation
no longer exists."
By the end of 2003, the most active jamming countries are China, Cuba,
Iran and Vietnam. The jamming emissions were also traced in North Korea,
South Korea, Morocco, Saudi Arabia and Mianmar. Besides, Cuba and Iran
are involved in satellite television jamming.
