the jet over the top can certainly hear him!
135.7 is FIA SFC - base of CTA. It used to be called "Melbourne RAS", and operated as a standalone position. When that was (and maybe still is, at times) you won't be transmitting over jets.
As I said earlier, how Airservices manages its frequencies and operating positions (i.e. resulting in retransmitting FIA onto frequencies used for CTA and vice versa) is not your problem. You need to comply with CAR 166 and AIP. If you don't, in the event of an incident, CASA may skin you -
I also make the point that the retransmission situation is not the fault of ATC. Its the result of their having to deal with staffing & workload constraints imposed on them by Airservices.
I think it is more about the majority of the GA community exercising 'Common Sense' and doing the practical thing.
Exactly.
