As of 2007, E03a made 8 broadcasts per day, 5 days a week. Only 14 messages were sent each month, scheduled throughout the week in a specific pattern. The first 7 messages were in rotation for the first 14 days of the month, with the other 7 airing during the remainder. Assuming that the messages are represented by letters A through G, the pattern was as follows:[2]
