Scheduling

All E11 schedules are weekly, follow year-round UTC (no DST adjustments), and use three different frequencies depending on the month - one for November to February, one for May to August and one for the remaining months. For most of the time there is no traffic, and one random week of the month a message is sent that always consists of 30-38 groups. Those always have a repeat transmission in the same week.

Most schedules are typically preceded by a digital transmission that delivers the same message that would later be sent in voice, on a nearby frequency.
