I'm with WestCoast and Danny here!
I used to teach my newbies "Get it right = Say it once!" as well as "Engage brain before pressing tit". In other words, learn the correct format, then apply it and you probably won't need to repeat yourself. Also "Rhythm, Speed, Volume, Pitch" when using HF; imagine you're talking to a deaf old aunt or a senior army officer, so speak in a way which will modulate the HF properly (particularly the old rubbish we had!) and not too fast either - so that the poor chap at the other end gets the message first time.
Mind you, certain nationalities asking for the rounders scores on 123.45, or endless 'ride reports' is another matter! As also is "Hello, New York, it's
the Birdseed *** at 340 right behind the Virgin...." which I once heard
We were military users of a mainly civil RT system. So it was only courtesy to play by their rules!
Oh well, back to "Golf Alfa Good Morning" on VHF LARS which is about my lot these days.
