Scheduled transmissions

Each E07 schedule consists of three broadcasts, spaced 20 minutes apart. The third transmission doesn't take place in case of a null message. The hundreds digits of each frequency of the schedule, when concatenated, give the schedule ID. Each schedule is weekly, and normally has a repeat transmission later in the week. The frequencies change monthly.

Exercise transmissions

The frequencies 10250 & 10256 kHz are used for presumed exercise transmissions of E07, M12, XPA2 and XPA. Those don't follow the scheduling rules described above. Broadcasts are made on either of those frequencies, and repeated 10 minutes later on the other frequency. There always is at least one simulated transmission failure in each broadcast.

E07 may use the voice of E06 in those exercise broadcasts, like it did in the past until early 2001.
