AREG Meeting THIS FRIDAY – Member Lightning Talks Round 2

Featured

The next meeting of AREG will be held on Friday October 19th starting 7.45pm. The topic for the evening is another round of Lightning Talks presented by you the members. The task is simple, you have 5 minutes to introduce or talk about your latest experiment, amateur related activity or idea. We have 6 slots so don’t be bashful, come along and tell us what has made you tick in Amateur Radio.

One of the talks will be a quick intro on how to decode SSTV using a 2m handheld and a phone – something that might be helpful for Horus 50!

A screen will be available provided you can deliver your talk via MS Powerpoint. Bring props or whatever you wish while the time keeper will keep proceedings lively by holding everyone to their 5 minute time limit.

The general meeting will be held after the talks so come along and meet your fellow AREG members face to face.

Visitors are always welcome too!

The meeting is held at the Fulham Community Centre, Phelps Court, Fulham.

OCDX Contest Low Band Antenna Test & Tune Day

The Low Band station team for the AREG OCDX effort this year are planning a working bee this Sunday (Sept 23rd) starting at 1pm. The aim is to erect, tune and test the 160m vertical that we plan on using for the contest. We will be using the vacant paddock on Lyons Road in Dernancourt just west of the Hope Valley reservoir (opposite the community hall).

If you would like to come and help, offer words of encouragement or go for a walk laying 700m of radials out, you would be most welcome. As the wavelength suggests, everything is big at 160m. The vertical will be 17m tall and have 16x40m ground radials so it will take a bit to get it in the air. Any help will be welcome.

We also plan on doing a verification test of the 80m vertical as well time permitting.


Update: 24th September – we had the antenna in the air on Sunday after a couple of mechanical hiccups. Tuning was proving a little complicated and an alternate matching network is being drawn up to overcome this.

Here are some photos from the tune and test day. A big thanks to everyone who came along and helped (VK5FGRY, VK5FO, VK5RR, VK5TST, VK5XDX, VK5SL, VK5GR, VK5SFA, VK5ZAR).

VK5ARG RD Contest Results 2018 – 1st Place Multi-One

The Remembrance Day Contest Results are out for 2018 and we are pleased to announce that VK5ARG scored first place this year in the Multi-One category with 875 points. Thank you team for all your efforts in the freezing conditions and we look forward to running it again in 2019! A special thanks also to Paul VK5PH who let us use his hills QTH for the event.

AREG September Meeting: Bends & Hitches not Knots!

Have you ever tried to put up a mast but struggled to tie things up so they stay in the air? Have you tried to sling antennas from trees but had them fall down faster than you could get them up? Have you struggled with rope craft in general but never had anyone to show you the right way?

As amateur radio operators, this is an important skill that will allow you to safely tie off ropes and guys so that your antennas and masts stay erect! So, why not come along to the next AREG meeting on Friday 21 September and learn from our resident rope expert how to do it right the first time.

After the presentation, there will be a break for a light supper of tea, coffee and cake where you can mingle and rag chew on the current events. This break will then be followed by an AREG club business meeting.

So remember folks, this coming Friday, the 21 September for the next AREG general meeting, everyone is invited.

Meeting time & Place: Friday, the 21 September at the Fulham Community Centre, off Phelps Court Fulham. The doors opening at 7:45 pm with the presentation starting at 8:00 pm.

AREG welcomes newcomers to the hobby!

Today AREG ran a foundation and license upgrade exam service at the club rooms. We are pleased to announce that we have 4 new amateur radio operators now joining the ranks!

The club would not have been able to offer these exams without the support of our examiners, so a big thank you is due to Ivan VK5HS, Chris VK5CP and Paul VK5PH for taking the time to come and facilitate for us.

The club would also like to thank those AREG members that popped into visit and offer support and take the time to assist our participants in feeling welcome, relaxed and even participate in the practicals. It was great to see everyone chipping in… To Gary VK5FGRY, Darin VK5IX and Chris VK5SA again a big thank you. A special thanks also to Leslie Levingston who took the time to bake a serious number of cupcakes as “brain food” for all to enjoy.

Once again a big congratulations to everyone that passed their examinations today and we look forward to seeing you get started on air. Your amateur radio journey is now beginning so please consider dropping in to the AREG at future meetings – you will find many people willing to help you along your way!

 

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

AREG and the WIA RD Contest 2018

RD Trophy

The Remembrance Day Contest 2018 has come and gone. This year AREG put it’s club station on the air from a new location thanks to Paul VK5PH and his new hills retreat. Just 20 minutes into the Adelaide Hills, this new location was absolutely RF quiet and had an excellent HF takeoff angle in almost every direction. At 548m ASL, it was only 150m below Mt Lofty (the highest peak in the southern Mt Lofty Ranges).

The operation was led by Grant VK5GR who supplied the station, with assistance from Andrew VK5AKH who supplied the main generator and AC power grid. Quite a few AREG club members came up to the site and helped construct the station, as well as Paul,  Gerard VK5ZQV and Paris VK5FPAR from AHARS.

The core operating team consisted of Theo VK5MTM, Andrew VK5AKH, Grant VK5GR, Mark VK5QI, Chris VK5FR, Matt VK5ZM and Paul VK5PH. Construction assistance was provided by Kym VK5FJ, Dennis VK5FDEN and Irene with catering provided by Sharon VK5FSAW. It was  great to see so many members braving the freezing conditions to make their way up the mountain to support the event. Special thanks to Andrew and Mark who also took on towing the rented port-a-loo up to the site.


Preparations began the week before when the first antenna was erected and tested. Paul, Gerard, Mark and Grant erected the 80/40m crossed inverted V antenna and tuned it in horrific wind conditions the previous Saturday (with winds gusting at 50-70km/h). That feat achieved meant that the following weekend things would go more smoothly (or so we thought).

The Friday night before the event saw Chris VK5FR and Grant VK5GR pack the station trailer ready for a 6.30am departure the next day. A huge thanks to Chris for his help.

On Saturday VK5GR, VK5FSAW and their daughter headed out along with VK5QI, VK5FR, VK5MTM, VK5ZQV and VK5PH and arrived on site around 7.30am. The first order of business was to erect the pre-tuned 40/80 dipoles into the air and then build the station. The weather hadn’t improved much over the previous week with conditions still somewhat blustery with rain and biting cold thrown in for good measure.

Once 40 and 80m was complete, the team turned their attention to the 160m antenna. This antenna was the same one VK5GR took to Vanuatu earlier in the year (that at the time he was able to put up single handed). This time, with the wind, rain, slush, mud and cold it was a very different prospect with numerous false starts and growing frustration as we raced against the clock and the weather. After about 90 minutes the first attempt was shelved as the weather closed in. The crew retreated inside the main shed to complete the setup of the station and get ready at least for 40/80 at the start of the contest. The team planned on returning to the 160m antenna project in the afternoon once the contest was running.

By a fortuitous mis-calculation, the team thought it started at 11.30am local and had completed preparations by 11.00am. This was fortunate as then the heavens opened. Down came the hail and sleet, up came the wind and boom went the thunder as antennas were hastily unplugged. It was as though someone didn’t like the teams presence on the hill. The temperature dropped even lower reaching 2 degrees Celsius at midday and the wind chill climbed. The thunder passed by 11.20am so cautiously the antennas were reconnected, only to be met with S7-9 hail static. Finally the worst of the weather passed and things settled down for the expected start at 11.30am. The clock clicked over and VK5ARG started calling CQ – only to see no one else on the band. A hastily recheck of the rules and the mistake was realized. Phew – three was another hour available to further preparations around the site.

The final bugs were worked out of the software system and some tidy up completed before finally opening on time at 0300z (12:30pm).

Mark VK5QI operating VK5ARG

By 0500z (2.30pm) the weather cleared enough that a second attempt at 160m was made. It has to be said that if it wasn’t for the calm arrival of Kim VK5FJ, VK5ARG may not have been heard on top band this contest! Finally, however, the inverted L was rasied into the air and tuned successfully. VK5GR was very happy to see it tune up with a 1.4:1 VSWR around 1840kHz with about 40kHz of bandwidth. It later was proved to work extremely well despite the horrible QRN (storm static) that was to descend across the low bands later that night (due to a large thunderstorm in the Tasman sea).

160m Inverted L built on a 12m Spiderbeam fibre glass pole (8x25m radials)

Back a the operating table, the station itself consisted of an Electaft K3S Transceiver, with a KPA500 Linear and a KAT500 tuner (needed for the CW section of 80m). The logging and CW keying was provided using N1MM software with a Microham Keyer II. All up a very capable station (with one niggle with a SW fault with the voice keyer on the K3S which is being investigated further).

As night fell, Paul VK5PH fired up the BBQ and all the operators were treated to a great meal thanks to the catering planning and shopping of Sharon VK5FSAW. Operators kept rotating to keep everyone fresh and the contacts rolled into the logs. Since the plan was to run for the full 24hrs, Paul VK5PH took the first shift in the graveyard zone (2200pm-0300am). Grant and Andrew then took over for 0300-0700 just as the temperature fell even further…

Overall, the bulk of the contacts were made on 160 and 80m at night and 40m during the day, with a small number of VK6 and VK4 stations on 20m. Nothing was seen on 15 or 10m despite repeated spot checks and the odd CQ call. None the less, the tally continued to rise, with a final score of over 530 contacts and 880 points. Most importantly, everyone who came had a lot of fun, despite the cold temperatures and the weather.

Finally, a big thank you to everyone from AREG and AHARS who participated and in particular a huge thank you to all of the amateurs across Australia and New Zealand who took part! VK5ARG looks forward to running in the RD Contest yet again in 2019!

VK5ARG in the Trans-Tasman Low Band Challenge Contest 2018

Another TT-Lowband contest has come and gone and this year AREG has set a new personal best score! A huge thanks to everyone who came along and operated, helped set up or sat in the bleechers cheering us on. A huge thanks to Steve VK5SFA who allowed us to setup a 3 seat Multi-Multi station in his home covering all three bands. Steve also fed the team (the BBQ was excellent) and kept us plied with copious quantities of coffee! The unofficial final score was 5360 points for 280 QSOs over the 6 hour event. We now eagerly await the official results.

The Station

The setup consisted of the following:

160m – 2 turn Magnetic Loop Antenna (which is barely 5kHz wide and difficult to tune in hunt and peck mode – much easier when we were running)

80m – we had a choice of 2 antennas – an Inverted V with it’s apex at ~9m above ground as an NVIS antenna and an 80m monopole which worked better for the longer paths such as ZL.

40m – we had a rotatory dipole as part of Steve’s SteppIR  Beam

The transceivers this time it was an all ICOM affair with:

An IC7600 and SPE-1.3KFA Amp on 40m,

An IC7610 and Elecraft KPA500 on 80m

An IC7700 and an AMCOM1000 on 160m

All stations were running 400W PEP simultaneously thanks to a set of 500W rated filters from Low Band Systems loaned to us by Peter VK5KX (thanks Pete!).

The Team

We had a great turnout from the club with lots of people contributing. Thanks must be given to Grant VK5GR, Mark VK5QI and Andrew VK5AKH who together with Steve provided the station equipment. Chris VK5FR also helped with installation on the day. We were also visited by Ben VK5BB and Olga VK5FOLG whom we are trying to recruit as future contest operators – great to see you drop by!

The operating team then consisted of Theo VK5MTM, Darin VK5IX, Steve VK5SFA, Grant VK5GR, Mark VK5QI, Andrew VK5AKH. Between the 6 of us we kept all three stations manned running CW and SSB for the full 6 hours – a fantastic result.

We also had Matthew VK5ZM and his son Daniel along with Darin’s son Cameron and Steve’s wife Linda as the cheer squad. It was all most pleasant being able to sit in the lounge chairs with the contestors going hard at it all around us. A fantastic atmosphere and a great night.

The Contest

So how did it go? 80m was the stand out band of the evening with it generating the majority of the contacts. 40m was great early on but once the sun set across the contest area the band filled up with stations from across the Pacific with the hum of several other contests running at the same time. Unfortunately the TT Low Band contest doesn’t allow you to log calls from other than VK & ZL so 40m became very hard going later in the evening. 160m saw a steady stream of signals throughout the night and was a lot of fun, although challenging to work search and pounce as it would take 2-3 minutes to change even 5kHz in frequency to call someone new on SSB.

All up the following map tells the tale of where we managed to work in the contest

Conclusion

Overall it was a great night and this year has cemented this as a regular fixture in the club’s contesting calendar! We now eagerly look forward to the results to see how we did!
