VK5RWN D-Star update

For information of all VK5RWN D-Star users, remote connectivity has been re-established late Wednesday evening, 21 October.

So users of Hot Spots, Dongles, DVAPs, you can again log onto the VK5RWN C or B modules.

If you have connection problems, you may need to update your hot spot Host Files. If the problem persists, email Ben VK5BB, and he will see what he can do to provide help.

You can also check the VK5RWN dash board to see connections and the Last Heard list,

vk5rwn.areg.org.au

For those interested in the technicalities, the problem was that when we reconfigured the local router that serves the VK5RWN D-Star computer, we missed setting some ports within the router to allow throughput.

The missing port numbers were not listed within the Icom manual for the setting up the D-Star system. However with some advice from a couple D-Star administrators, we identified the missing port numbers and I also then found them in older set up documents that were not checked in our search for answers. Isn’t that always the way of it?

It turns out that these ports are not needed by the main Icom D-Star system, which was working well without them, but are used by third party software that has been added to the D-Star operating system that allows additional services within the D-Star networks.

Have fun exploring and playing with D-Star.

VK5RWN DSTAR – We’re Back!

We are pleased to report that thanks to the hard work of our dedicated volunteers, in this case Matt VK5ZM, Ben VK5BB and Bob VK5FO, we have completed the cut-over to our new Internet link!

The VK5RWN D*STAR repeater has been reconnected to the internet as has the Weather Sonde receive station. The VK5RWN D*STAR Gateway is active and hotspot users should also be able to connect again to our host server.

(Note: Hot spot users may have to wait a few days to allow the Host Files to update VK5RWN’s IP address. It is also recommended that hot spot users log into their hot spots and force an update to the Host Files).

AREG has now moved to a new internet provider. We would like to thank Phil and Christine at Kern Internet for their help in re-configuring the on site router!

Other Dash Boards associated with VK5RWN are also back online, including the registration page and user access to their accounts.

(You may need to allow a security exception to access the pages the first time you log in via the vk5rwn.areg.org.au.)

Adelaide D*STAR users who are not already members of AREG are encouraged to join our group or make a yearly donation to our running costs, to support the D*STAR system here in Adelaide.

We hope you enjoy our return to service!

  • VK5RWN 2m 147.0375 +600kHz
  • VK5RWN 70cm 438.400 -5.4MHz

Note if there are users in Adelaide that want to experiment with the 1.2GHz ports, please contact us and AREG can look at re-activating them. They were disabled originally after they sat idle for 2 years consuming power for no reason. If interest in D*STAR on 1.2GHz returns we can turn them on again.

VK5RWN D-STAR Update – Progress!

As D-Star users in Adelaide will be aware, the club’s VK5RWN repeater has been disconnected from the Internet for several weeks now. This is due to AREG needing to change internet provider, coupled with installing a new microwave link to the site. This also created downstream problems with the LAN design and router configs at VK5RWN. We are happy to report that we have now made some good progress, with the link to our new provider Kern-WiFi successfully commissioned.

We are not out of the woods yet however. Running multiple 24×7 services on the live internet while making sure the site is not open to hostile online attacks is not a trivial exercise. It is taking us longer than originally hoped, to secure the new connection and re-open all of the services from VK5RWN (including the BOM Balloon tracking station and the DSTAR repeater).  With luck, that should be done in the next 7 to 10 days (after the Oceania DX Contest is complete this weekend).

Stay tuned for further updates! Meanwhile, local D-STAR contacts are still possible via the VK5RWN over the air on 147.0375MHz (+600kHz) and 438.4MHz (-5.4MHz).

VK5RWN D-Star repeater Network Link off line!

AREG has, for a number of years now, operated the internet link for VK5RWN via a number of free member provided services. Alas, our last member in 5.8GHz range of VK5RWN (who doesn’t have trees in the way) has left the area.

As a result, AREG is now moving the DSTAR internet service to a paid internet service (Kern WiFi) so the VK5RWN D*STAR gateway can continue. The new service was installed on Friday the 4th of September. We hope to complete the remaining network reconfiguration work over the next 2-3 days. As soon as thats done, D*STAR network services will be restored.

Meanwhile, the VK5RWN D-Star repeater is still fully operational as a local (2m & 70cm) DV repeater. However, as there is no Internet network connectivity at the VK5RWN site, remote linking of repeaters, reflectors and hot spot connectivity is not available.

AREG is sorry for any inconvenience that may be experienced, however please bear with us while we work to restore service within the next few days.

Can you help Us?

With the substantial increase in operating costs, AREG would encourage any and all D*STAR operators in the Adelaide area to consider becoming members of AREG or at least consider a yearly donation to the club. This will help cover the now more than $1000+ per year running costs for power and Internet.

Your support of the Adelaide VK5RWN DSTAR node is greatly appreciated!

VK5RWN D-Star system upgraded to allow linking to XRF & DCS reflectors

For those who came in late………….

The VK5RWN D-Star gateway and repeater system was upgraded in May June 2018 with a new computer running 64 bit CentOS 7 and the new Icom G3 gateway software.

Between then and March 2019, the system has proven to be relatively stable with only a couple of minor hiccups where the computer has shut itself down? We believe this may have been due to the CPU over heating or something similar? This is still being addressed.

VK5RWN is a D-Star gateway system, registered on the US Root Trust database and primarily runs an application called Dplus which manages the linking and routing functions on the D-Star Internet network between other D-Star gateways/repeaters/reflectors.

As such, users are able to connect to other repeater/gateways and Dplus based Reflectors anywhere around the World, or even to other registered D-Star users via Call Sign Routing, a bit like a “private” call in the commercial PMR world.

In principle, within the D-Star world, there are two D-Star Internet networks, the Dplus/US Root Trust network and the ircDDB D-Star open network. Again in principle, the two are mutually exclusive networks and are not interconnected.

This creates an issue where D-Star users accessing the “D-Star World” via a Dplus connection cannot connect to other gateways and reflectors that are using the ircDDB network and vice versa and are therefore limited to accessing the Dplus REFxxxX reflectors. (eg REF023C)

Hams being hams, they just cannot help themselves, the challenge was there and so software was developed that when installed on the Dplus Icom based gateways, allowed interconnectivity into the ircDDB networks and allow access to the XRFxxxX and DCSxxxX based reflectors. One version of this software is called “g2_link” and is designed to be added to existing Icom based D-Star gateway systems on the US Root Trust network.

Early March 2019, Michael VK5ZEA, who is custodian of the VK5REX D-Star system on lower Eyre Peninsular, advised me that he has rebuilt the VK5REX system and had successfully installed the “g2_link” software with the help of Terry, KA8SCP. Michael also passed on Terry’s contact details, whereupon I made contact and asked Terry if he would mind assisting with installing the “g2_link” software on VK5RWN.

Terry most kindly agreed to assist and arrangements were made that allowed Terry to install the software and set up the necessary configuration and interlocks so that both the Dplus and the ‘g2_link’ accessed networks could be worked via VK5RWN.

This now allows for D-Star users to access VK5RWN via a RF input from their D-Star radios and they may now access both the REFxxxX, XRFxxxX and DCSxxxX reflectors and gateways.

A bonus as part of this new configuration, new Dashboards were part of the set-up and now show the connection status and ‘Last Heard’ lists of the VK5RWN system.

Have a look at

For D-star users, please read the instructions at the bottom of the XRF/DCS Dashboard. This is important as there are two distinctly different “linking” or “unlinking” commands to connect or disconnect to and from REF reflectors and the XRF/DCS reflectors. This is so that the system can differentiate between a request via Dplus or the ‘g2_link’ and allow the respective link request to be actioned or disconnected.

It is recommended for D-Star users to use VK5RWN Port C, the two metre port, for connecting to any of the reflectors as VK5RWN Port B, the 70cm port, is normally permanently connected to the REF023C Australasian/Oceania reflector. Before connecting to a reflector, please ensure that the Port is not currently connected to anywhere else. The VK5RWN B 70cm port may be used, but it must be disconnected from REF023C first.

I wish to thank Michael VK5ZEA for his support and advice and especially Terry, KA8SCP, for his help, patience and advice where I needed to do some house keeping that allows VK5RWN to function as a flexible D-Star gateway, allowing D-Star users access to the big wide world via both the Dplus and ircDDB D-Star networks.

AREG IRLP & DSTAR Gateways Back in time for JOTA

 

After several months of disruptions due to lightning and HDD failures at both the VK5RSB IRLP node and the VK5RWN DSTAR Gateway AREG is pleased to announce that we have been able to restore both services in time for this weekend’s Jamboree on the Air for the Scouting and Guiding communities.


VK5RSB Internet Relay Linking Project Node #6214

The IRLP Node 6214 will be available for use by users supporting JOTA this weekend, 20, 21 October. The node can be accessed via the VK5RSB 70cm repeater on 439.900 (-5MHz) using a 91.5Hz CTCSS access tone.

In the support for JOTA, the prefix access code has been removed for this weekend, thus allowing free access to the node.

Therefore to access remote IRLP nodes,

  • dial in the 4 digit DTMF node address of the remote node.
  • to disconnect the IRLP connection, just dial “73” a the end of the QSO.

AREG wishes the JOTA teams and other users, to have fun with contacts via the IRLP Node 6214.


VK5RWN DSTAR Gateway Restored for the 2m/70cm repeaters

The VK5RWN D-Star repeater and gateway is also now fully functional after its computer rebuild. It’s new computer has been installed and the gateway configuration is now complete using the new ICOM G3 software.

Currently the configuration is;

  • Port C, the 2m port, is unlinked and available for general use or user linking to reflectors and gateways etc (147.0375 +600kHz)
  • Port B, the 70cm port, is permanently linked to Reflector REF023C and will output any activity on this reflector and will repeat local RF activity on the 70cm channel into the reflector network. (438.400 -5.4MHz)

NOTE: Port B may be disconnected from the link to REF023C with the unlink command, “^^^^^^^U” , (the ^ represents spaces)  then it may be connected by the user to another address.

VK5RWN activity is now being reported to various Dashboards,

D-Star network access seems to fully functional. Ben VK5BB reports that he has tested linking to several reflectors through the local gateway as well as connecting directly to VK5RWN via his JumboSpot hot spot successfully.

So, any members or DSTAR users in Adelaide who have an interest in D-Star, have D-star capable radios and are registered on the D-Star system, please give VK5RWN a try out and feedback will be appreciated please?

VK5RWN Internet Gateway Failure – Local Mode Only

Dateline: August 18th 2018 – The VK5RWN D-STAR gateway computer and therefore the D-STAR repeater networking is off line due to a failure of the current computer’s SSHD storage.

Both the 2m and 70cm D-STAR DV repeaters are still on and available for use providing local coverage as D-STAR DV repeaters, however there will not be any access via the VK5RWN gateway to the D-STAR global network until further notice. It will only support local operation for the next few weeks.

The current gateway was very shortly due for an upgrade anyway, so the existing failed unit will not be repaired. The new VK5RWN D-STAR gateway computer will be installed on site, pending some minor works, ie, a new shelf, and the final installation and configuration of the new G3 gateway software. This software has to be installed and configured on site as it needs to see both the D-STAR repeater controller and the respective Ethernet ports during the final configuration.

So sorry folks, the D-STAR gateway system will be down until the new computer has been installed, over the next couple of weeks, pending time available.

If you wish to work outside of the Adelaide area on D-STAR, you will need access to a DV Hot Spot, a SharkRF OpenSpot or JumboSpot, DVAP, Dongle etc.

Please pass this information on to any others who you may hear trying to use the VK5RWN D-STAR system

VK5RWN D-Star repeater site antenna tower replacement.

Back in mid August 2017, the tower supporting the antennas for the VK5RWN D-Star repeater system was damaged during the big blow that accompanied the storms. The tower, which was a section of a Hills Telemast bolted at the roof line of the communications hut, has been in service for about 27 years and was in good order. It appears that the wind loading had been exceeded during the August storms and the tower was bent just above the roof line of the building and the top section with the antennas was approximately 30 degrees off the vertical.

Well, no option, it had to be replaced!

The working bee at the VK5RWN site was scheduled for Tuesday 19 December 2017.

Ben VK5BB was at the site around 0845 hrs local time and the other members of the work crew arrived shortly afterwards.

Apart from initial preparations, and the OH&S site survey, the first job of the day was to erect the scaffolding, on the roof of the building! Gave us very easy access to all antennas for disassembly. The scaffolding was also used for the reassembly, thereby minimising the need to actually climb the tower, though Colin VK5ACE later did, to re-mount the 2m antenna at the top.

From there the antenna equipment was easily removed and the bent tower was cut off just above the bend in the tower (just above the roof line) and the tower easily removed. The coaxes were laid out to one side so as not to be damaged and ready for re-installation.

Whilst the old tower was being removed, other members bolted the new tower sections together ready for erecting. The new tower is two sections of Hills 330mm Butt Section mast, with additional plates fitted at the join of the two sections to provide some additional strength at the join.

The top end of the new tower was lifted (man-handled with ropes) above the adjacent hut and then the base lifted into position near where it was to be mounted. Using the ropes, the tower was then pulled upright, across the gap between the two buildings to its mounting position, loosely bolted in place whilst we marked out where the base bolts were to go, drilled and fitted the Dyna bolts and the tower was firmly bolted in place. Actually went in place quite well with a minimum of jiggling etc!

Lunch time! (about 1300 hrs local)

After lunch, the antenna cross arm and antennas were refitted, thanks to Colin VK5ACE, the main climber/rigger for the day. As the Wi-Fi dishes were refitted, the day started to get a bit blowy but the dishes were pointed approximately in the right directions. The 2m 7 element Yagi for the Broadcast Source transmitter was re-installed as a 3 element Yagi and pointed at Crafers. All coaxes were resealed, dressed and cable tied to the tower.

All antennas are back in their old positions, determined by the lengths of the various coax feeds. The tower, now 9m high, carries a 2m, a 70cm and a 23cm vertical “white stick” collinears, two 200mm Wi-Fi dishes and a 3 element 2m vertical Yagi.

Job done!

All equipment was turned on again and the various systems tested, we even had the Internet back on at the site, so we did get the dish right, either that or it has strong side lobes. (The Internet connection was previously still working even though the dish was pointed at the sky? A relay from the ISS??)

Clean up, and we were gone by 1700 hrs local.

The D-Star operations were checked at the site and later again from Ben’s QTH and all was good, including remote access to both the D-Star and the Broadcast computers.

Crew on site;

  • Trevor, VK5ATQ, roustabout and also supplied the scaffolding, (NERC member)
  • Rod, VK5ZRK, roustabout, (NERC member)
  • David, VK5MDF, roustabout, (NERC member)
  • Colin, VK5ACE, rigger, (AREG member)
  • Jeff, VK5IU, “supervisor” and roustabout, (AREG member)
  • Ben, VK5BB, project manager, 2nd climber/rigger, (AREG member)

Many thanks to the crew who helped during the day and especially Olga VK5FOLG, as she supplied a fresh cut lunch for all and delivered on site about 10 minutes before the lunch break.

Reports from the D-STAR users have reported a significant improvement of signal strengths at Balaclava and Mt Barker on 2m and from Hallet Cove on 70cm, so all appears to be good again.

Next task for the VK5RWN D-STAR system is the upgrade of the computer to a new 64bit system running CentOS 7 64 bit and the new G3 gateway software. This is scheduled for early in 2018.
