Typical scheduling

M14 schedules are scarce, because most regular traffic from the agency operating it is now digital (F06, F01). However, it is not uncommon to hear unscheduled M14 transmissions, which also adhere to the rules described here.

Typically M14 transmits on the hour or at the half hour, but may also start at other times within an hour. The transmission is often repeated 30 or 60 minutes later, on a frequency that is either higher or lower by 1-3 MHz than the one on which the previous broadcast was made. In case traffic was sent, the two transmissions are often repeated also the next day at the same times and on the same frequencies - but different times may also be used.

The M14 speeds vary - 15, 20, 25, 30 and 40 WPM ("PARIS" standard) are all used.

20-group messages

M14 also has schedules that only send 20-group messages. Unlike E06 and G06, which have one each, M14 has three, and two are converts from schedules that in the past mainly sent the non-traffic format. The messages they give are always 20 groups long, and are non-random in appearance. The messages are re-used for 1-2 years.

The transmission format also slightly differs (see above).
