First discovered in 1981, E21 is a numbers station that’s very similar to that of E05, using almost the same format for the messages. The majority of the time the station used 4-figure groups instead of the usual 5. In some rare instances it did use 5 digit groups. The station ceased operations in March 1995.
It’s voice is also another version of E05’s, with a higher pitch and tempo.
