Thought I’d move this over here,
It’s an interesting one - the principle for the ACMA per this doc, is that their limiting it to ‘solus markets’ uses a definition of a market that includes where there’s a 30%+ overlap.
That is an interesting question for 2MW then - as surely the overlap that matters is the one in the other direction. Only 26% of the Gold Coast license area population is in Murwillumbah, so surely it’s not a competition issue under that definition, and as I’d think BOG would/should point out - if it’s enough of an overlap to be denied an FM conversion, they’d be enough of an overlap to be deemed as the same market for being on Gold Coast DAB.
Suppose spectrum congestion would be the main issue even if the ACMA did agree it wasn’t a competition issue, maybe a local would know better how viable using 104.1 or 103.5 at higher power would be?
The only other station that pops in my head as a 1 station overlap AM market is 3EL in Maryborough - though the huge overlap there would rule it out of contention I’d think.
