2. World Radiocommunication Seminar (Geneva, 8-12 December 2008) 2 Workshop ITU HFBC package

3. World Radiocommunication Seminar (Geneva, 8-12 December 2008) 3 Introduction to the ITU HFBC software package General principles: Consistent with Article 12 and Resolution 535 of WRC-97. Developed in consultation with administrations, broadcasters, and coordination groups. Takes into account the availability of suitable computer hardware by administrations to run the software.

7. World Radiocommunication Seminar (Geneva, 8-12 December 2008) 7 ITU HFBC Calculation software The main HF module, linked with the data capture module. Propagation prediction: calculates propagation data; results in tabular form or on maps. Compatibly analysis: calculates interference from other requirements; identifies interference sources; results are shown on maps.

9. World Radiocommunication Seminar (Geneva, 8-12 December 2008) 9 HFBC VAL Data validation software Designed to assist administrations to validate quickly their HFBC requirement files: Article 12 HF bands. Regional coordination groups bands. Remove requirements with frequencies out of the Article 12 bands.

11. World Radiocommunication Seminar (Geneva, 8-12 December 2008) 11 HFBC ANT Antenna calculation program Theoretical approach based on Recommendation ITU R BS.705 Calculates the radiation patterns and gain of the most common used HF antennas. Provide quick reference for administrations and broadcasters in identifying antennas.
