NSW P25 GRN - Site Listing (current)

[Bigfella237]

Checking a heap of other sites (not all, just random sites here 'n there) and it seems most of the underground sites have a similar notation, be they road or rail tunnels, but very few of the above ground sites, even in-building sites, have this.

Then I remembered somebody here saying that they'd seen certain agency radios denied on the La Perouse site and sure enough, it has "CO - Station open to official correspondence exclusively" as well.

Mascot International Station has a slightly different version again:

"Nature of Service OT - Station open exclusively to operational traffic of the service concerned"

I tried to find a list of these codes and their meanings on the ACMA website but had no luck.

So it appears if a site is installed for a specific agency (electricity, railways or whoever), they are denoting those sites as above and restricting their use?

I guess I'll have to go through all the sites and note which are and which aren't eventually, but not tonight.

At a high spot near me (120m ASL) I received a faint control channel on 422.4500MHz. The 996 decoded it as 02d1h-0112. It had Gosford and Newcastle services traffic. ACMA shows it is one of the new 420MHz frequencies at Tower 2 Mt Elliot Gosford. The existing 416.4125MHz CC seems to have been switched off.

Thanks Mike, site 001-012 has been updated as above.

And more big news, I've just received over a dozen site numbers for those CCEP North West sites we had as unidentified... Watch this space!

Okay, the following sites have now been updated on the NSWGRN Map and also on the Zone 2 list here of the forum:

RFSS 002 Site 061 - FORBES (Comm Site Manna Mountain)
RFSS 002 Site 062 - YELLOW MOUNTAIN (Telstra Site)
RFSS 002 Site 063 - TRUNDLE (Adv Energy Site 1.7 km NE of Gobondry Trig) *Was site 002-072 on our list but now moved to 002-063
RFSS 002 Site 064 - BURREN JUNCTION (Optus Site The Ponderosa Kamilaroi hwy)

RFSS 002 Site 066 - COBAR (Country Energy Site Caronga Peak)
RFSS 002 Site 067 - PILLIGA (Comm Site Come by Chance)
RFSS 002 Site 068 - GIRILAMBONE (Telstra Exchange)

RFSS 002 Site 072 - NYMAGEE (Telstra Radio Terminal Nymagee Mountain)
RFSS 002 Site 073 - QUAMBONE (Telstra Radio Terminal)
RFSS 002 Site 074 - TRANGIE (Bogan-Cathundral Road, Cathundral, 21 W of)
RFSS 002 Site 075 - BOOROOMA (Telstra DRCS Base Six Mile Tank)
RFSS 002 Site 076 - CRYON (32677 Kamilaroi Highway)
RFSS 002 Site 077 - LIGHTNING RIDGE (Springvale Cumborah Road 29.7 km South of Walgett)
RFSS 002 Site 078 - CONIMBIA (925 Toora Road)

RFSS 002 Site 084 - CARPENTERS HILL (4 km NW of Glenn Innes)
RFSS 002 Site 086 - MUNGINDI (Broadcast Site 3km SE of)

And obviously the above were also removed from the Unidentified Sites list. As far as I know that just leaves three sites out that way to be identified:

Unknown Site # - CARINDA (Telstra Exchange)
Unknown Site # - GULARGAMBONE (Telstra Site Misery Farm Castlereagh Hwy)
Unknown Site # - WARREN (Telstra Site Mount Foster)

EDIT: I've just been doing some housekeeping on the list... I've checked the ACMA page of every single one of those "Microwave Relay Sites" (there are 135 of them ATM) looking for wide area freqs that have been licenced since I last checked, but there were none.

And I've cross-referenced all the voice channel freqs with the CC list (see here) for any site that is missing either a CC and/or an AltCC, and I've marked any possible frequencies licenced there which may fill the vacancy, or where there was only one other voice freq found on the CC list I just took a punt and moved it to the AltCC.

No doubt there are a hundred other things that need doing but I'm sick of staring at a computer monitor for today, so anything else can wait!

I was up at Port Macquarie last weekend
Still all quiet up there on the GRN site front (ie nothing from the local site Telegraph Pt

Still quiet at Telegraph Point as at 25/3/19

Unknown Site # - RYDE (Top Ryde City Retail Cnr Devlin St & Blaxland Dr) - ACMA Site: 9010154

And it's frequencies have a similar notation:

"Nature of Service CO - Station open to official correspondence exclusively"



Which leads me to believe that there IS actually a site there, and that it's for the exclusive use of one user in particular, and that explains why it can't be monitored and has no peers?

Hmm... now I'm gonna have to go looking for these notations on other sites...

Andrew

A good find Andrew.

So now the question is, what users would Top Ryde be limited to? As far as I am aware there is no power infrastructure there, so unlikely EA/Intergral?

It would be reasonable to assume, being a shopping centre, it would be used by the emergency services. But if that was the case one would think it would have been picked up by somebody at some time since coming online all those years ago?

[Bigfella237]

Spooky timing... there are 5 new GRN sites that appeared on the ACMA today, the rest I will add later but one of them is 4 new HSGA frequencies at Top Ryde SC (ACMA Site: 9010154)!

But the assignments are slightly different, they are all on a DAS (whereas the original freqs are on an "UNKNOWN" antenna system), they don't have the 'exclusive' notation, and they all have different "Station Names" whatever that means?

418.675 MHz (8.3 W) = "Station 220"
419.175 MHz (8.3 W) = "Station 221"
419.425 MHz (8.3 W) = "Station 222"
419.675 MHz (8.3 W) = "Station 223"

The original freqs have "NEW SOUTH WALES RYDE" (with the frequency appended) for the Station Name, although I must admit I've not taken any notice of the Station Names on any other site either.

And finally, these assignments aren't linked to site 001-005 like the other ones are.

So buggered if I know what's going on but I think that confirms that there's definitely at least one GRN site there?

I just went down the list of stores again and still nothing jumps out at me, there's a Ryde City Council office and an Australia Post outlet but AFAIK neither of them are on the GRN, and there's nothing else remotely govt. related.

Unless whoever it is isn't listed on the "stores" list, which is not impossible if it's just an office for someone, it may be located on a floor not easily accessible to the public? And the site may be very localised, maybe to just one floor, or even to just one office?

We would need to know exactly what each of those notations means, it is different from the Energy Australia tunnel's notation, whether that was just entered incorrectly or whether that means something different I don't know?

All possible, but the site seems too big for just one user - it’s at least 11 channels, where the other ‘single user’ sites are only 4 channels.

I wonder if it’s the case the site used to be there pre-demolition, and maybe it was never reinstalled? From memory they rebuilt the place around 2005 (ish?). You’d still think someone would have picked it up though prior to that.

Was the old property that was demolished also called "Top Ryde City Retail"? Wouldn't it have been a different ACMA site number? And if that was the case, why would they add 4 new bases today to a site that didn't exist?

I'm convinced now more than ever that there IS a GRN site there, I know a number of members here have had a hunt around inside the complex and received nothing, but the special notation may explain why it can't be received in the public areas, the site was never there for general purpose users, although that may have changed with the latest addition of extra bases?

[Bigfella237]

Those 5 new sites licenced today that I mentioned before actually turned out to be only 2 (both doubled-up under 2 different Client IDs, with the 5th site being Top Ryde).

So the following new GRN Sites were just added to the NSWGRN Map and to the Unidentified Sites list here on the forum:

Unknown Site # - STRATHFIELD (Telstra Exchange 68 Beresford Rd) - ACMA Site: 4631
418.6125* = "Station 7"
418.8625* = "Station 8"
419.1125* = "Station 9"
419.3625* = "Station 10"
419.6125* = "Station 11"
419.8625* = "Station 12"
420.1125 = "Station 1" (and no, my 'paste' key didn't get stuck, these are all called "Station 1")
420.3625 = "Station 1"
420.6125 = "Station 1"
421.3625 = "Station 1"
421.6125 = "Station 1"
421.8625 = "Station 1"
All frequencies on "Dipole-D, BA80-67, RF INDUSTRIES", 10K1F9W, 80W, 33.65 m Antenna Height (AGL)

Unknown Site # - REVESBY (Ausgrid Substation, End of Tarro Avenue) - ACMA Site: 9015053
418.7000* = "Station 19"
418.9500* = "Station 20"
419.2000* = "Station 21"
419.4500* = "Station 22"
419.7000* = "Station 23"
419.9500* = "Station 24"
420.2000 = "Station 1"
420.4500 = "Station 1"
420.7000 = "Station 1"
421.4500 = "Station 1"
421.7000 = "Station 1"
421.9500 = "Station 1"
All frequencies on "Dipole-D, BA80-67, RF INDUSTRIES", 10K1F9W, 80W, 35 m Antenna Height (AGL)

* Frequencies with an asterisk are licenced to the HSGA Client ID
Frequencies in RED are found on the CC List

Not sure what's going on with those "Station Names", it obviously doesn't relate to the GRN site number so I suspect that (if it means anything) it may be the location of the equipment in the racks on site?? Anyway, unless we discover some important hidden meaning, I don't think I'll bother continuing to list them on future additions.
