High Frequency Broadcasting Schedule

​​HF Broadcasting Schedules are issued at the end of each month with the exception of June. They contain the combined scheduled notified to the ITU by the Administrations or other broadcasting organisations for the corresponding season. Schedules are generally posted two weeks after the end date for submission.

In order to facilitate the communication between the BR and the notifying organizations and the coordination of the HFBC requirements through the use of modern electronic communication means, the publication of HFBC schedules and compatibility analysis results on CD-ROM was discontinued from 1 January 2019 and replaced by free of charge online publications.
