CIA reports about amateur (ham) radio in the former Soviet Union (including the Baltic States) and Warsaw Pact member countries have been declassified to a new online search engine.
The website is: https://www.cia.gov/library/readingroom/search/site/amateur%20ham%20radio
The documents include translations and assessments of : amateur radio clubs, including DOSAAF; training; monitoring sputniks; technology and equipment; and even qsl cards.
All the documents have been de-classified and made available to the public for the first time in this internet archive; some were previously available in a closed system at the US national archives.
