Scheduling

All G11 schedules were weekly, followed year-round UTC (no DST adjustments), and used 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 was no traffic, and one random week of the month a message was sent that always consisted of 30-38 groups. Those always had a repeat transmission in the same week.
