Secret Military Listening Posts
BBC2 Coast Saturday 5:45

Thanks to Mike Barraclough for spotting that this week's edition of Coast on BBC2 (repeated Saturday evening) features items on Top Secret Military Listening Posts - Y Stations and Cobra Mist.

Top Secret Military Listening Posts - Y Stations
Experiment being carried out to show how Y Stations worked. During the Second World War Sheringham Cliffs was the location of a top secret listening post - a Y Station. Hermione Cockburn uncovers the story of the work that was carried out at these stations and meets up with former Y Station operator, Joy Hale. After the war the stations were
deliberately dismantled, so how did they work?

With the help of experts Fraser Robertson, Peter Seabrook and Malcolm Howard, Hermione finds out how these radio listening posts helped spy on German forces.

'Cobra Mist'
'Cobra Mist' at Orfordness
In the cold war year of 1967 the ever-present threat of nuclear war with the Soviet Union loomed large. This site at Orfordness became home to 'Cobra Mist', an over the horizon radar designed to spy deep into the eastern bloc. Neil Oliver investigations lead to the full glory of this massive radar being recreated using computer generated imagery.

The programme is repeated on Saturday 4th at 5.45 p.m.
