So experiance will fill in the unintelligible bits, Great!!
what about if you don't have this yet ? there also seems to be a competition by some controllers as to how fast they can talk (
I know they are under pressure) but if they have to repeat it takes longer, & if you misunderstand their instruction either because of poor quality of Tx, speed of delivery & your inexperience and nervousness of asking controllers to repeat more than once, You could Die and take others with you
There appear to be as many if not more poor unreadable radios flying as on the ground.
