Position and Hold at uncontrolled field

Remember that there are a lot of student pilots and low time pilots who have
a hard time learning to use the radios.

Fair enough. But I'm thinking of pilots who should be able to do
better, but who simply have never given a thought to how their radio
hogging is messing up others.

One of the hardest things I have to do as an instructor is not jump in and
'help' my student on the radios or make his radio calls for him.

Sure, students need to practice using the radio, but please take them
to a quiet field and frequency to do so. To let them flounder on the
air at a busy field is simply dangerous.
