Keg,
Don't get me wrong, it's nice to have someone remind you when you've had a bit of finger trouble and transmitted on the wrong frequency (god knows how many times I've done it), but if you'd have heard the carrying on that happened the other day you would see why this thread was started. The pilot clearly stated that he was 'on guard' and was making a check call to Amberly Ground. This was then proceeded by every man and his dog telling the poor bloke he was 'on guard', and he couldn't get a word in edgeways. Not very professional at all by those involved, and very frustrating for the pilot concerned and Amberly Ground.
