Operation

E12 operated on weekly schedules. However, each schedule sent only one message each month. The only group counts noted were 10, 15, 20, 25, and 30 - all being multiplies of 5.[2]

E12 had originally broadcast alongside its German counterpart G12. E12 replaced it completely in June 1994.[3]
