AREG at the AHARS Buy N Sell 2016

Posted on by

It has been a busy month and this news is a little late – but better late than never! The committee wants to thank all of those members who participated in the club’s fundraising efforts leading to the AHARS Buy N Sell event this year. The club again was able to muster a wide variety of items for the tables and trade was brisk.  A lot of preparatory work went into the event lead by Scott VK5TST who hosted many working bee’s preparing items for sale.  On the day, the club was represented by Grant VK5GR, Mark VK5AVQ, Chris VK5SA, Andy VK5AKH and Scott VK5TST . Thanks team for a job well done!

Mark VK5QI, Kim VK5FJ, Matt VK5ZM and Grant VK5GR at Maker Fare 2016

The Amateur Radio Experimenter’s Group achieved it’s goals of putting amateur radio before the public at the Adelaide Maker Faire 2016 held on November 6th, with a huge amount of interested generated from the stand and the 15 minute presentation given at the event by Mark VK5QI on Project Horus. Those who manned the stand couldn’t be happier with the response, and genuinely hope to hear further from a number of people who have had their interest sparked in the hobby in the near future!

A huge thank you has to go to Kim VK5FJ who coordinated AREG’s presence, as well as to Mark VK5QI who prepared much of the Project Horus material for the stand. A number of other members also spent most of the day there manning the stand promoting Amateur Radio, as well as to those members behind the scenes who helped with preparing publicity handouts and business cards for the event (Scott VK5TST, Gary VK5FGRY and Mark VK5QI). A huge thank you to all of you as well!

AREG certainly hopes to be back at the Maker Faire in 2017!

Balloon Launch November 13th: Horus 38 – 10:00am ACDT

Posted on by

The Amateur Radio ExperimentersIMG_1767-1024 Group is planning another High Altitude Balloon Launch. Designated Horus 38, it will be an internal project team flight carrying payloads specifically for AREG members. Multiple payloads will be included.

UPDATE: Due to the high wind conditions at the launch site, most of the payloads did not make it off the ground (including the video and SSDV payloads). Currently only the LoRa Cutdown payload is in the air. Chase teams are en-route to recover this payload now.

Flight Track Prediction

The following is the predicted track for the balloon tomorrow. We will be targeting a 5m/s ascent rate, a 30km burst altitude, and 7.5m/s descent rate.

SSDV Experimental Payload – ‘Wenet’

Mark VK5QI and David VK5DGR have been working on a slow scan digital image payload for the balloon system which transmits at 115kbit/s on a new downlink channel. This system makes uses of the UKHAS SSDV server to stitch together images from packets uploaded by multiple receivers. It first flew on Horus 37, and after some refinement will be flown again on this flight. Information on this system is available here.

HD Video Camera Payload

We are also going to fly an upward facing and an outward facing camera, and hope to collect images of the balloon expanding and (hopefully) bursting, as well as some HD video imagery similar to what was achieved back on Horus 12. Thanks to Scott VK5TST and Josh VK5JO for the loan of the GoPro Hero3 cameras for this flight.

RTTY Telemetry

The standard RTTY 70cm telemetry payload will be flying as well. Listen out on 434.650MHz USB, 100 baud  ASCII-7N1. You can get involved through capturing telemetry data and relaying it back to the chase team via the Internet (details on how to setup and operate dl-fldigi are available here: ukhas.org.uk/projects:dl-fldigi

Flight Details

Visitors from the Amateur Radio service are welcome to come along to the launch this time (as it is not for a school or other organisation). Launch details at this stage are below, however keep watching the website closer to the time for confirmation and up to date details:

  • When: 13th November (Sunday), approx. 10AM CDT launch time.
  • Where: Mt Barker High School Oval

AREG at the AHARS Hamfest 6th November

Posted on by

AREG will again be present at the AHARS Buy’n’Sell event on the 6th of November! This yearly event, is a regular on every Amateur Radio Operator’s calendar in Adelaide and is not to be missed.

Apart from amateurs there will also be commercial retailers of amateur equipment in attendance. This is an ideal opportunity to pick up that new item without the cost of freight.

AREG will have much on offer!

The AREG has been lucky this year and has obtained a large amount of surplus equipment that it will be able to offer to the Amateur Radio community in Adelaide. This will include lengths of LMR400 coax, repeaters and many other components and gadgets which are useful to anyone who constructs anything electronic at home. So, come on down to the AHARS Buy’n’Sell. Doors open at 9.30am!

Report: AREG Participation in OCDX SSB Contest

Oceania DX Contest VK5ARG Field Day station Cancelled

Despite the weather, AREG members still made sure that the club call-sign VK5ARG was heard on the bands for the Oceania DX Contest, albeit from the QTH of one of our members and not from the planned portable operation. The unprecedented weather system that rolled through South Australia in the days before the contest, coupled with the storms that arrived Sunday meant that the field day activation simply wasn’t possible this year.

Relocation to the Murray Mallee activated as plan C

In order to get VK5ARG on the air, a hasty retreat was made to the Murray Mallee where Chris VK5CP has his remote station. There we had access to two stations covering 20-10m and 40-10m respectively. On the Friday afternoon we also erected a temporary antenna to give us access to 80m and 160m for the contest!

Most of the crew who planned to activate Para Wirra Park made the journey out to the Mallee and so we were able to man 3 stations when required. Those who participated were:

The contest itself was also hard going. The sun and the ionosphere did not cooperate well. This was reflected in the score achieved. At one point during the contest the T-Index map looked like this:

It made for some peculiar propagation. 15m was open for a time when no contacts could be had on 20m during the day on Sunday. At night, we also had some great signals on 80m including contacts to the US West coast and the Mariana Islands. 40m however was our standout band, having extended openings to the USA Saturday evening and to Europe Sunday early morning.

Conclusion

Overall, a great time was had despite the difficult propagation. Everyone enjoyed themselves.

The final score achieved was:

A very special thanks must be expressed to Chris VK5CP who bailed us out when the weather threatened to scuttle our participation completely. Thanks also goes to all of the contest organizing committee, band captains, operators and support crew who did make the trek out to the Murray Mallee to operate and support VK5ARG, including: VK5AKH, VK5ZM, VK5XFG, VK5GR, VK5MTM, VK5KX, VK5QI, VK5IX, VK5FGRY, VK5FSAW and last but not least VK5CP!

Thanks also goes to everyone who worked very hard preparing the station over the preceding 3 months. Don’t fear, your efforts have not been in vain as a suitable activation of the park will be planned in the near future (so that all of the work can be put to the test).

Till next year! 73s de VK5ARG!

Oceania DX Contest: VK5ARG will still be on the air!

Posted on by

Given the weather and park access situation we are faced with, the AREG has taken up the very kind offer from one of our members to still participate in the Oceania DX Contest from his remote QTH.

You will still find VK5ARG on the bands, although with fewer transmitters than originally planned. Hope to hear you on the air calling CQ DX CONTEST!

VK5ARG/P Para Wirra Park This Weekend Cancelled

Posted on by

AREG OCDX Contest Field Day Event

CANCELLED!

Due to the unprecedented weather in SA over the last few days, National Parks South Australia have advised that Para Wirra Park will again be closed today. This has lead to AREG making the decision to cancel the planned activities in the park.

Operation in the contest will still go ahead but from a private location. See further reports for updates.

The Amateur Radio Experimenters Group is again entering the Oceania DX SSB Contest over the October long weekend (October 1st and 2nd).

The club is once more mounting a major portable operation from Para Wirra Recreation Park. VK5ARG will be active on all bands from 160-10m during the contest using 5 QRO (high power) stations.

Station Visitors Most Welcome!

As has been the case the last couple of years, the station construction will commence from Friday morning, with the aim of having the major components operational no later than midday Saturday. This provides an ideal opportunity for members, but more importantly general amateurs and members of the community, to come along and “have a try”. AREG will be turning the station over to all takers for the hours before the contest so that people can experience operating the station.

To come and visit, you will need to head to Para Wirra Recreation Park, You will find us here. For those who pre-register, there will be catering available on a “Pay as you Go” basis for modest prices. The station will be active for the full 24hrs from 0800 UTC Saturday to 0800UTC Sunday. Visitors should call the station on 2m (146.550) when you reach the park.

Para Wirra Park Map

The Station: VK5ARG/P

The station will be substantial with full size rotatable dipoles on 40m, a 3 element beam on 20m, a Spiderbeam for 15m and 10m and full size dipoles on 160m and 80m. All stations will be running 400W. It is certainly impressive to see the arrays of antennas in use during the event…..

Qualification of World Wide Flora and Fauna park: VKFF-1739

Back in May 2016, the Para Wirra Recreation Park was redesignated a conservation park, and so it now qualifies for the world wide flora and fauna awards program as well. As the station is operating in the OCDX contest we wont be conducting the usual publicity of a parks activations. However, contacts with VK5ARG/P will still qualify for the VKFF-1739 park! We will ensure the log is uploaded to the Parks and Peaks database at the conclusion of the activation. You may also find us on air testing from as early as Friday night through to Sunday night.

So look out for us calling CQ during the contest, and if you are in the Adelaide area, come on up to Para Wirra Conservation Park and say hello! We would love to see you!
