Aircraft scatter can be used on bands from 2m upwards and up to 500km range is achievable, depending on the band and geography. The talk started with some audio examples of aircraft scatter.

8th Jan 2020 - LRS Video Night - "The Cold War" at Edinburgh Cine & Video Society
- Details
- Written by Alan GM3PSP
There was a turn-out of 15 for the LRS 2020 Video Night, presented by Peter Dick GM4DTH on 8th January 2020 at the Edinburgh Cine & Video Society in Fettes Row. Peter chose two films about the Cold War.
Spy in Bonn receiving a "Numbers Station".
The first was a short (14 min) from ITN Roving Reports called "The Spy Catchers" (1963). The setting is Bonn in West Germany and gives an indication of the level of espionage from the communist bloc.
Western propaganda stations targeting the USSR
The second film was called "Empire of Noise" (2006) and ran for 50 min. The title refers to the sound of the jamming modulation used by Soviet jamming stations in the short-wave broadcast bands prior to the fall of the Soviet Union in 1990. With jamming modulation playing throughout the film this was a realistic but really depressing view of the world of SW broadcasting in the 1950s onwards, fortunately now gone forever.
