Holy smokes Ovr! Maybe we got an exclusive here?!
People like City_ and the armed forces still use a phonetic alphabet to identify letters. (Ie. the letter F= Foxtrot ; U= uniform ; *= Charlie ; *= kilo)
Or as Snowman prefers: F= Foxtrot ; A= Alpha (or Able) ; C= Charlie ; *= Kilo
Personally, I find morse code more efficient and quicker but you have to keep using the code to remember it. All three are used internationally tho.
