Chili:
Your post was food for thought. I'd never considered the problems of a new atco before, I guess it isn't usually obvious. BTW, my experience is that the Bristol team are amongst the most GA friendly in the UK, whether LARS service or app/ad. However, pity Bristol's training prices (for visitors, at least) are so high.
Drum:
All pilot's, I'm sure remember their first attempts at RT. Don't be afraid or embarrassed, only fools will laugh. Don't let communication problems interfere with your flying of the aircraft. Good luck.
