Koori isnāt an HPON though ā itās a community broadcast service.

The spare HPON on AM is for Penrith (1386 kHz). However, there is an unused community AM allocation for Sydney (783 kHz).

I assume getting the AM community licence would be a pathway to broadcasting on the community radio allocation on DAB+ also?

I always thought that was an interesting choice of frequency given the geographical proximity to Gosford, where 801 is a 5kw HPON.

783 kHz was of course the old 2KA frequency. Iāve always thought the 1215 Bowral/1224 Western Sydney/1233 Newcastle troika more problematic. Then thereās 1017 Sydney and 1035 Wollongong with 18 kHz spacing; not a problem as far as I know.

Yes, you could add in 1206 Canberra there as well possibly.
I see 1224 has sharp nulls to the north and south to protect 1215 and 1233.
1224 is stronger than 1233 up the southern end of the Central Coast so it seems to do okay within its licence area, although it does need that 100.5 repeater for the city and eastern suburbs.

Thanks for the correction, quite sure it was a HPON focusing on indigenous programming, but not. 
I didnāt know which thread is most appropriate for this, Vale Kevin John:

Thanks @NDY, thatās unexpected to me, what happened?
So much more to offer, a fantastic talent, set such a great standard in broadcasting and humanity.

Iām not quite sure yet, but Iāll probably find out over the next few days. Tragic loss for the town.

I had another look & listen to the station today.
The audio is definitely sounding better compared to 10 days ago.
Looking at the SDR waterfall I can see the improvement to the transmission, but thereās still one or two problems. See attachment image below.
Appears there is:-
- Some noise or low level modulation of the carrier & 19kHz sidebands into or from their own transmitter. During periods of silence from Koori Radio I can still see modulation or noise on their carriers. Later I saw some carrier drift too.
- There is either some substantial multipath interference at my RX site or there is another weaker transmission underneath the main 93.7MHz that is causing interference to the station.
Areas circled in lime green are periods of silence.
Ideally should only be seeing thin lines (carrier + 19kHz carrier & harmonic sidebands) against a blue background.
If the station didnāt inject any audio into the transmitter for a period of 10 minutes of so I could notch out the main carriers with the SDR software of their signal & listen for another potential source of interference.

I wonder if SEN can licence this one for SENTrack.
Donāt they already have 1539? We donāt need more horse racing on the air.

I wonder how long the mast at Luddenham will stay in itās existing position, it is very close to the under construction runways at Western Sydney Airport and will be a hazard to arriving and departing aircrafts.
I totally agree but I am surprised he didnāt try to buy it given its available.
No we donāt, thats for sure.

Perhaps this topic should be under Narrowcasting forum, anyway I was looking for the 1386kHz MW mast at Luddenham in the ACMA database, but couldnāt find one at the provided coordinates in Google Maps, but did find the mast for 1611 at Badgerys Creek nearby. Maybe same mast? And yeah, that mast will probably have to be moved I suspect re proximity to proposed runway.

What are the decimal coordinates?
@crankymedia 1386kHz coordinates are: -33.866203Ā°,150.721442Ā°
from ACMA. Site description says itās a Nominal Planning site;
āNominal Planning Site Lot 12 corner Elizabeth Drive and Luddenham Rdā
Site accuracy 10m
So maybe no mast ever constructed for 1368kHz?
Was there a service on 1386kHz in the past from Sydney?
