For goodness sake...just leave the bloody thing alone.
More changes will be against safety. We know what the rules are and no-one to my knowledge has died because they called on Area instead of Multicom.
What's the use of me picking up Joe brown calling at Yowling Creek airfield if I don't know the thing exists or where it is?
I like listening to the bigger fellows when I am in remote areas and find their "presence" rather comforting. Joe will only be on air if he is flying and the way GA is going, that won't be very often.
