Ok, I tend to talk fast on the radio. I also like to keep it short and to the point. Why is this a problem? Unless I am talking so fast the other side cannot keep up then there is no disadvantage. The number of occasions I have had a please repeat is probably running at about 1 a year on 75 ish hours flying.
The people who get up my nose are the ones who start their life story and forget what they were witling on about ½ way through. If more people thought what they were going to say before pushing the button, life would be easier and safer for everyone.
