There was once a rumour that CASA was going to discuss this very issue at safety seminars. Never happened to my knowledge and possibly never will but perhaps the issue could be raised with them. I certainly will next time they visit.
On another note, I observe that the chatterbox's are the most difficult to engage and the least likely to hear others broadcasts.. Old mate who speed reads his arrival with great brevity is usually the exact opposite and will hear and note everything.
