All S11a schedules are twice weekly, follow year-round UTC (no DST adjustments), and use one of three different frequencies depending on the month - one from November to February, another from May to August, and yet another for the remaining months. The first two digits of the ID identify a particular schedule.

On each schedule, only null messages are broadcast for the majority of the time. However, traffic is sent at least once every month, on a seemingly random week. The standard group count range is 30 to 40 groups inclusive. Sometimes, extra messages may be delivered within a month that may exceed this range.
