Jammers

During the Cold War era, the Radio Free Europe directed transmissions to East Block countries (from the Munich area), which were heavily jammed with fluctuating multi-tone machine-sounding modulation. The RFE transmitted the same program (various reports, news, DJ music, etc) on different SW bands, such as 16,19, 25, 31, 41, 49m SW (it was announced as this). The bands used were different during the day, night, winter, summer. However, it became known, that there is always 1 frequency, where the program is not jammed. So with a little fiddling with the buttons, one could find a clear transmission (I have checked out this myself, and it was true). The reason of leaving 1 frequency not jammed was (known as) the local authorities wanted to tape and listen in the programs, too! From time to time the jammers transmitted an id marker in morse. [thanks for the info, AC]

Note: I mentioned Rimantas Pleikys' book "Jamming" before. He describes these stations extensively. A list of the markers and their locations can be found in his book.
