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.

VK5RWN DSTAR Repeater Damaged – Repairs Pending

In the wild weather over the past few weeks the VK5RWN repeater system has sustained some structural damage.  The original tower section is currently bent at a rather alarming angle and will require replacement.

In the past few days we have had our repair crew up there to shore up the tower section and make temporary repairs until a more permanent solution can be found.

There is still internet connectivity to the site and the D-Star repeater is still operational for the time being.   Users may find that the coverage of the repeater is somewhat disturbed however.

In the coming weeks the antenna system will need to be upgraded, so there will most likely be a prolonged period where the system will be off air while repairs are being made.

VK5RWN Internet connectivity re-established.

wncdstar_logoFollowing up from the previous report that VK5RWN D-STAR system was off line due to site mains power failure.

Well the power came back on last night, 13 July 2016, but the internet connectivity did not?

A site visit this morning, 14 July 2016, identified that the POE power supply had died.

This is one of those little Blue QSKJ inverter modules that lifted the 12 volts to 16 volts to feed the router switch and the Ubiquiti WiFi unit up the tower. The faulty unit was replaced with a loan unit.

With the POE PS restored, connectivity was re-established and all is now good. Confirmed that the VK5RWN D-STAR system was fully operational and reporting to the respective D-STAR reporting sites.

Feedback on VK5RWN’s performance and operation may be sent to AREG, vk5arg@wia.org.au or the D-STAR Systems Administrator, Ben VK5BB, vk5bb@wia.org.au

VK5RWN D*STAR Repeaters OFFLINE – Mains Failure

During the wild weather in Adelaide over wncdstar_logothe past 48hrs, VK5RWN’s mains power was lost. Batteries held the site up for a while, but due to the extended nature of the outage these have now been exhausted.

AREG is monitoring for the mains power to be restored and will bring the system back online as soon as we can.

VK5RWN D*STAR 23cm 128kbit Data port in hibernation

wncdstar_logoThe Amateur Radio Experimenter’s Group wishes to advise that the 1299.700MHz 128kbit/s port of the VK5RWN D*STAR node has been placed into “hibernation”. In the entire life of the repeater this port has been accessed 3 times, and so rather than continuing to pay to keep it active it has been switched off. The equipment remains installed however so if you do desire to experiment with this aspect of D*STAR it will be a simple matter of contacting the club, and we can go and re-enable it for you. (This is to help further combat the $1000+ power bill the club foots to run this site each year).
