E21 – 4F Counting

First discovered in 1981, E21 is 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 operation in March 1995.

It’s voice is also another version of E05’s, with a higher pitch and tempo.
