WA Radio Scanner Users' Group

Joss wrote:G'day all,

I am wondering if anyone has a program to interpret the data FESA transmit. Is it FSK or similar? Will Skysweeper or similar software decode it or is it encrypted? Can a second hand radio with data screen from ebay be modified to view the information the VSUs get? Anyone out there any good with this sort of thing?

My scanners are old and don't have the ability to use CTCSS to cut out certain transmissions, so I am unsure if the data and the voice are seperable using CTCSS - eg if I spring for a decent scanner that has CTCSS can I cut out the data noise and monitor only voice traffic?

Also, what freq range in VHF hi and UHF will the new emergency radio system be (if it is already out..)?

Thanks everyone,
Joss

I dont think you'll find any hardware that will let you decode the VSU traffic - its some proprietary system built by a WA company. With regards to the data transmissions, a scanner with CTCSS and Tone Squelch will get rid of them, but I wouldnt run out and buy one - the data transmissions will be no more soon, so you'll end up with voice only on those frequencies in the near future.

And the new radio system is a few years off yet.. apparently they have VHF Hi allocations which can be found in the ACMA database - not sure about UHF though..

You'll want to put in all the 6AR frequencies into their own bank and scan them for a while, taking note of which channel is the clearest.

Now that you have the FESA working channel for your area, you can program in some of the interesting channels like the water bombers. The car to car channels of 46-49 and 96-99 should be good, too.

It looks like FESA have an allocation in the area of 450-460 MHz.

Are the channels activated to be listened on a scanner though???

Haven't heard anything about encryption and doubt they'd use it.

When I try and print the freqencys it come out blank, can someone tell me what FRS/BFB use around South West Metro (Freo area).

Cheers

hey daZ

6ip: channell 80: 78.4125
or 6ar: channel 55 78.1000

thats wat i pick up well in kwinana

If ch55 for 6AR doesn't work for you in Freo, try Ch51 (Claremont)

Did some checking today.

An SES radio I saw recently had the following channels/frequencies...

SES 1: 459.100 MHz (Input for WAPol Ch31)
SES 2: 469.125 MHz (Input for WAPol Ch32)
SES 3: 459.150 MHz (Input for WAPol Ch33)
SES 4: 459.175 MHz (Input for WAPol Ch34)
SES 5: 457.675 MHz (ACMA lists Nowergup and Bremer Bay)
SES 6: 457.725 MHz (ACMA lists Nowergup and Scarborough)
SES 7: 457.975 MHz (ACMA lists Greenmount)
SES 8: 458.225 MHz (ACMA lists Serpentine and Rockingham)
SES 9: 457.325 MHz (ACMA lists Wireless Hill, Ardross)
SES 10: 457.425 MHz (ACMA lists Walliston)
SES 11: 468.600 MHz (Output for WAPol Ch31)
SES 12: 468.625 MHz (Output for WAPol Ch32)
SES 13: 468.650 MHz (Output for WAPol Ch33)
SES 14: 468.675 MHz (Output for WAPol Ch34)
SES 15: 467.175 MHz (ACMA lists Nowergup and Bremer Bay)
SES 16: 467.225 MHz (ACMA lists Nowergup and Scarborough)
SES 17: 467.475 MHz (ACMA lists Greenmount)
SES 18: 467.725 MHz (ACMA lists Serpentine and Rockingham)
SES 19: 466.825 MHz (ACMA lists Wireless Hill, Ardross)
SES 20: 466.925 MHz (ACMA lists Walliston)
EMS A: 458.025 MHz (Emergency Channel A)
EMS B: 458.075 MHz (Emergency Channel A)
FRS 1: 519.625 MHz (UHF Fireground channel 1)
FRS 2: 519.900 MHz (UHF Fireground channel 2)

While looking for Fireground channels on the ACMA database I discovered that there are no allocations in W.A. for 519.900 MHz and that each Career F&RS station in the metropolitan area has a licence for 519.625 MHz and also 472.075 MHz. I've never seen any reference to that channel before but the licence says that FM narrow (F3E) may be used.

I've noticed that too. I suspect the 472.075 Freq is a for public address paging. Will have to camp outside a fire station one day when I have little to do and find out

Neither 458.025 or 458.075 are licensed either.

the licence for emg a and b is held by wapol

I have heard 519.900Mhz & also 519.625Mhz used locally here in Bunbury by handheld radios on simplex when required.

The ACMA Database does'nt list frequencies licenced and used as "WA Wide" or "Western Australia" they can only be found searching by licences and checking each licence one by one.

The are heaps ( possibly hundreds) of frequencies that are unsearchable that are used by say Government Agencies - eg The Dept of Fisheries that you cannot find using the online frequency seach facility.

The frequency 494.975Mhz is used by The Dept of Fisheries WA Wide http://web.acma.gov.au/pls/radcom/assig ... ID=1610077

but searching using that frequency won't bring up The Dept of Fisheries but alot of other users who use that frequency in their own locality however searching all the Licences held by the The Dept of Fisheries will reveal alot of WA Wide or Western Australia Frequencies with that being one of them.

The datebase needs to add a function that allows searching a WA Wide allocations, even 468.925Mhz ( CH44) used by Busselton Police recently for a concert event does'nt have a registered licence listing on ACMA - it is a WA Wide special event allocation.

I know it has been asked a fair bit, but has anyone actually recieved anything on 472.075 MHz yet? I have been too busy to stop by a fire station (and there isn't one close to me anyway) to listen. Must be a firey around that has some idea.

Hey, can anybody tell me what frequency FESA use for their paging?

Thanks

In the country it has traditionally been channel 99 (76.550MHz). In the city I have no idea.

Paging is done through commercial companies, such as 3 Paging (formerly Orange) - some might even use Link still.
