I wouldn't change the characters for anything.
As an Instructor the characters at Scottish info have made the student learning curve of pressing the tit one of enjoyment instead of terror.
You guys probably don't realise the tone of your voice and your patience does way more to encouraging students to use the service available than any number of briefs on airmanship and RT.
I am sure some prat who has never been near a PPL student would have issue with "Roger G-xx take a deep breath you nearly got it that time and now say again"
As an instructor I say crack on it aids flight safety.
And PS whats wrong with 300knts above FL100 in class G.
