Welcome to High Frequency Co-ordination Conference homepage
HFCC is a non-governmental, non-profit association, and a sector member of the International Telecommunication Union in Geneva in the category of international and regional organisations. It manages, and co-ordinates global databases of international shortwave broadcasting in keeping with International Radio Regulations of the ITU. The HFCC provides representation, tools and services to its members for the resolution or minimisation of instances of mutual interference among shortwave transmissions. Organises regular conferences prior to the start-dates of seasonal broadcasting schedules that coincide with the dates of clock-time changes for the summer and winter periods. There are two seasonal schedules and their validity is global. The schedule designated "A" corresponds to the summer, and "B" to the winter period on the Northern hemisphere.

What's New
