I am checking FMBC from Australia by MROFFT software these days.
And found from Mount Isa have the carrier-like signal on 107.3MHz.
It is very useful to check weak TEP path but only 107.3 have it for a long time.
(I could see it on 106.5 too but it did'nt continue long time)
107.3 carrier-like signal continues long time but sometimes stops.
I can't find go and stop pattern yet.
The attached file shows a good sample when the carrier-like signal was cut off halfway through.
Why 107.3 have carrier-like signal on FM mode.
And why no others?
I guess in Australia uses a different FM broadcast modulation method than JA.

I can hear FMBC stations from Mount Isa every night these days.
101.7 102.5 103.3 104.1 104.9 106.5 107.3
And around equinox we can hear high-power FMBC stations from Cairns
101.1 105.1 105.9 106.7 107.5
and from Townsville
101.5 104.7 105.5.
Attached files are 104.7 from Townsville and 105.1 from Cairns.
Both seems to have carrier-like as the same as 107.3 from Mount Isa.
(only 1 time I could see trace on those frequencies this August)
My antenna is 6el yagi for VOR.
So lower frequencies are no good because of gain.
Anyway it is curious for me to see carrier in FM modulation on 107.3MHz.
There was talk of it being turned on across the ABC network some years ago but the funding wasn't available then, maybe things have/are changing in that regard.
