In my area the radio calls made by some of the students (foreign and local, VH and RAAus) do little more than alert you there is another aircraft.... somewhere.
Not YCNK or YMND by anychance....often hearing that lovely deafing squeal of 2 transmissions in at once because some clown wasn't listening...
Wouldn't it be nice if casa could come up with a DVD or do something useful to try & get everyone speaking the same lauguage on the radio, christ it's not that hard but so many pilots some experience & some not so can't get it right or even come close
Don't even get me started on the training standards of some schools around the area
