In Australian Class G, are you required to have your VHF switched on if you're VFR and nowhere near the vicinity of an aerodrome at which carriage of VHF is mandatory?
But clear of a CTAF or BA, where does it say what frequency has to be tuned?
The introduction of the MULTICOM would make a standard frequency for all low level ops clear of CTAFs and BAs. But then you have the gliders and PJE ops that use their own frequencies, so there will always be exceptions. But better than having a choice and contributing to congestion on the Area Freq.
