Welcome to ENIGMA 2000
ENIGMA 2000 is a UK based online group, whose aims are to bring together listeners and enthusiasts who monitor and gather information on 'Number Stations' and other related radio transmissions. Through our Yahoo Group monitors can share their logs, discuss frequencies, thoughts and opinions on this most emotive subject.
ENIGMA 2000 maintains the ENIGMA Control List, the definitive listing of number station identification.
ENIGMA 2000 produces a two-monthly newsletter giving details of frequencies of current stations and provides quality information on subjects not normally available from main-stream publications.
The ENIGMA 2000 Newsletter can be downloaded from this site. Members can also download it via the "Files" section of the ENIGMA 2000 Groupsite.
ENIGMA 2000 also offers written guides to finding and identifying stations complemented with a current selection of sound sample clips.
