On the 19th January 2006 there was the biggest re-alignment of UK and European NATO UHF airband frequencies since 1987. This involved about 98.5% of the known UHF frequencies that can be monitored from the UK being changed. Around 920 new ATC and discrete UHF frequencies were identified and included in Airwaves 2006. Airwaves 2007 added a further 392 new frequencies and this years Airwaves 2008 adds another 165 new frequencies plus over 160 frequency changes.
