I believe it was that champion of GA Dick Smith who wanted ti stop all the radio calls to save money.
The saving money part included grouping area frequencies with control frequencies which we have today.
But the chatter didn't stop - it just meant that all the crap RT now jams up the centre / approach frequency when so ATC instructions can not be issued / heard.
Great progress.
While we are on it how about some of you who are the culprits read the AIP on exactly what has to be read back (too much in the AIP to start with) or at least ask an (experienced) instructor.
Include in that what is required when under radar control - it differs. Example: ATC are supposed to give a reason for radar vectors - you don't read back the reason!
Some of the RT I hear for a simple circuit entry you would think the Space Shuttle was returning to Edwards AFB with an emergency!
