For those of you who listen to Shanwick radio, you might be interested to learn that there is a plan for increased use of HF, and indeed for the provision of additional HF frequencies in 2011. This is from the Irish Aviation Authority website:
Shanwick Radio keeps in contact with all flights in Oceanic Airspace mainly by means of High Frequency Radio (HF), but also uses VHF (Very High Frequency) and Satellite Phone (SATPHONE). HF can provide global coverage because of its ability to bounce off the ionosphere and can span the globe in a series of skips. VHF coverage, on the other hand, is limited to line-of-sight range. Shanwick Radio uses over 20 HF frequency channels and 2 VHF. At peak times it handles in excess of 1400 aircraft in a 24 hour period. In 2008, the station handled in excess of 1 million messages from 422,086 aircraft. To cater for the growth in HF frequency activity it is planned to introduce additional frequencies during 2011.
