Those of you who are incredulous at
Duke16's post should read it again; it's a fact.
It's actually the reason Dick S wants the US system here; it's really simple.
I see that elsewhere there's a post saying that somebody goes into an aerodrome which isn't a CTAF/MBZ and intimates that terminal comms are a problem. This is a classic example of lack of education [which will sink this NAS proposal {and me happy to keep the status quo, BTW}] to cross the cultural boundary in introducing a mature system from another place.
Let me explain carefully; if you are flying to an aerodrome that is not in a CTR or MBZ,
IT IS A CTAF!! You use 126.7 [if there's no other freq allocated] to communicate at a distance appropriate to your speed to let folks know you're coming. Simple.
If you're operating at an aerodrome which isn't at or in a CTR or MBZ and doesn't have a non-126.7 allocated frequency, you should be listening on 126.7 if you have an operable radio.
Hope that helps a bit.
G'day
