I think 132.9 went into the 'special events' frequency pot along with 121.17 and the like. I'm pretty sure that in recent years I have used it, maybe for event ATIS or temp helipads. We never got any calls over Great Orme Head though…
I'm trying to remember the Northern RASA freq where we used to thread Norjets from the Pole up to Buckden and Stainmoor thence across to NV and NT without bumping into somebody… Anybody from Lindholme remember the annoying tannoy "civil controller to console 5b…" ?
…and, interestingly, 126.65 is my current day-job second-hand freq…!
