DMRDecode build 36 now out!

from Radio Reference Forums, Ian Wraith has updated DMRDecode to build 36.

Hi Folks
I have just put build 36 up onto Github ..

https://github.com/IanWraith/DMRDecode/downloads

This new build comes with a number of new features including basic Capacity Plus decoding.

NSW Government Radio Network (April 2011 Update 2)

The NSW Government Radio Network (GRN) has now been entered into the RadioReference.com database.
You can see the entry here @ http://www.radioreference.com/apps/db/?sid=6943 includes a list of sites with control channel and alternative control channel frequency, as well as the voice channel frequency for each site as well.  A list of talkgroup id's are also available, broken up into agencies and includes known alphatags and channel numbers.

NSW Government Radio Network (April 2011 Update 1)

As you all know the NSW Government Radio Network has gone digital! The majority of the 160~ sites are 100% P25 Digital with a few sites still having the old analog control channels alive for a month or so more, but basically the old system as we know it is finished.



The sites are setup into zones, Zone 1 (Sydney and Central Coast), Zone 2 (Western NSW and Newcastle), Zone 3 (ACT, South Coast and Southern Tablelands)

Just like the sites, the talkgroup id's are also setup into zones, 1xxxx belong to Zone 1, 2xxxx belong to Zone 2, and 3xxxx belong to Zone 3, with the exception of some agencies including NSW Fire Rescue. ACT Agencies have talkgroup id's of 4xxxx.

Agencies that use the NSW Government Radio Network that have been heard so far are,
NSW Rural Fire Service, NSW Fire Rescue, NSW State Emergency Service, Ambulance Service of NSW, ChildFlight,  Corrective Services, AusGrid (Energy Australia), Integral Energy, Roads and Traffic Authority, Sydney Ferries, NSW Maritime, Juvenile Justice, Sheriff Department of NSW, Sutherland Shire Council, Railcorp, ABC News, and a few unidentified users. In the ACT, the ACT Ambulance Service, ACT Fire Brigade and ACT Rural Fire Service, ACT SES as well as ACT Parks and Conservation.

At this stage, only a few number of users are using encryption. Those include Corrective Services who are trialing it on talkgroup 10402.

DMRDecode build 32 now out!

A new build update is available for DMRDecode, current version is now 'build 32'

can be found here https://github.com/downloads/IanWraith/DMRDecode/dmrdecode_b32.jar

from the author Ian Wraith from RadioReference forums:

'New features include a "Pause" button to stop screen activity if you see something interesting and the radio logged feature at the bottom of the screen now shows which channels (timeslots) the radios used (as suggested by Forts).

Also I have fixed a bug which prevented you starting logging again once you had stopped logging.'

Non-Government P25 Trunking System (Sydney)

A non-government P25 Trunking site located at the ABC Tower (Gore Hill) at Artarmon, run by company Airwave Solutions, they have 5 registered frequencies with ACMA at this site. Airwave Solutions according to their website are running a trial P25 Trunking system to demonstrate to potential customers the capabilities of a P25 Digital Trunking System. Here is an extract from a news article from their website..

Airwave Solutions Australia has unveiled the P25 Solution Centre, an industry initiative with the aim of demonstrating to the Australian market the performance and maturity of the P25 open standard with equipment supplied by multiple vendors.

As a dedicated operator of critical government infrastructure, Airwave understands the importance of choosing the best and most compatible technology for an organisation. It is with this in mind that Airwave partnered with P25 industry equipment manufacturers and suppliers (including Tait Radio Communications, Harris, Auria Wireless, ComGroup Australia, RFI, ICOM and Zetron) to bring the P25 Solution Centre to market.

The P25 Solution Centre provides an environment that allows visitors to test and verify the equipment and applications from multiple vendors, and also confirm the value of the options available in the Australian P25 Communications market. This is made possible for customers through their participation in live demonstrations of equipment from multiple suppliers working together within an integrated environment as specified by the user as well as the ability to configure radios from different manufacturers, to then use on alternative manufacturers infrastructure – again as specified by the user.

GRE PSR-800 decodes X2-TDMA

GRE has confirmed that it's new PSR-800 pre-programmed digital scanner will decode both APCO-25 digital AND X2-TDMA which is an early variation of APCO-25 Phase II TDMA digital. This is very exciting and important news in the scanner world. Currently X2-TDMA is used by select public safety agencies in the Washington D.C. area, particularly in Prince Georges County, MD. Up until now no scanner could decode TDMA. X2-TDMA is not the final spec of APCO-25 Phase II but we believe it will likely be quite some time before the final specifications are announced and equipment is manufactured. Thus the PSR-800 will not be able to decode a future unknown specification. In the meantime though, for people in the DC area and possibly other areas in the future, the PSR-800 for now is the scanner of choice.

NSW Fire Rescue Station ID's

Thanks to Steve Banham, Stations 3.0.0.5 is out, Stations is an application for the Windows that displays/lists station numbers. Very useful when monitoring the NSWFR on the GRN and for example Runner 1 or Pumper 43 callsigns are used, you can match them up using this application.

You can visit Steve Banham's blog page at http://sbanham.wordpress.com/2011/01/15/stations-3-0-0-5/

and you can download the application from here!
