interesting - I'd have thought UHF might have had fewer line-of-sight issues - inherent in mountainous areas at low level.
Glad we are all talking to each other now!
I just hope that the military VHF radios are up to scratch. Had great fun trying to understand what the HMS Illustrious based helicopters were trying to say on VHF radios which were clearly never used last year (before decommissioning).
