There also is a small variant format E07a.
Transmissions use either AM or USB mode. Until March 2018, the speed and the pitch of voice samples was increased by +10% in AM mode.
Scheduled transmissions
Each E07 schedule consists of three identical transmissions, spaced 20 minutes apart. The third transmission doesn't take place in case of lack of traffic. The hundreds digits from each transmission, gives 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 frequency other than the first broadcast. There always is at least one simulated transmission failure in each broadcast.
E07 may use the voice of E06 in those exercise broadcasts.
