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.

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

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!

AREG RD Contest 2016: Member Activity Report

Posted on by
RD Contest Trophy

RD Contest Trophy

The Remembrance Day Contest for 2016 has come and gone. AREG was well represented this year with a number of home stations as well as three portable efforts making their presence felt across the bands.

Three members, VK5AKH, VK5MTM and VK5GR banded together to form a three station team this year. Named “AREG: Mostly Harmless!”, it gave the club an avenue to participate in the contest whilst also allowing individuals to also work for an individual score. It will be very interesting to see how they placed!

A further three members, VK5WTF, VK5QI and VK5KX also gave it a go! The following are the stories from those who took part:

Andrew VK5AKH – Portable Sedan

Andrew headed out to a remote site and set up a formidable station. He finished up with 286 contacts and 294points. it was a fair effort to built this station as a single op on Saturday morning and as hard as he was pushing he missed the start of the contest. The 3.5+ hours of assembly had its toll later in the evening when he was a little tired. Next time antennas will be set up on the Friday leaving me fresh for an evening. A good time was had…

Grant VK5GR – Portable Tickera (Spencer Gulf)

Grant set off Friday night from Adelaide and arrived in Tickera, on the eastern shore of Spencer Gulf around 8.00pm. Station setup began bright and early Saturday morning. By 9.30am the basic station was running, so the extra time was put to use adding 160m dipole elements to the 80/40/20m mix. This was the multi-band resonant dipole’s first outing and it proved to be a very good field performer. After the contest it even allowed a quick PSK31 contact to Reunion Island on 20m no less!

During the contest, Grant made a point of operating for as many hours as possible, stopping only for ~1.5hrs around 5am for a quick nap. The effort paid off with 469 contacts and a total of 664 points (thanks to the graveyard shift multipliers). 160m paid off handsomely as well, with 41 contacts and almost a worked all VK Call areas in 8 hours (except for VK1 who didnt appear on the band). This was the first time Grant had operated on 160m and with luck now wont be the last!

Grant also experimented with RTTY this contest. While there were very few RTTY stations around, those he did work certainly helped his score, including his first 160m digital contact into VK4!

Theo VK5MTM – Home Station

Theo managed a Personal Best of 286 QSO’s/300 points. Operating from home, he had to battle solid S9 noise on 40m during the daytime and plasma TV noise 80% of the time on 20m (neighbour’s TV). Even so, a very respectable score was achieved!

VK5MTM-RD

Marcus VK5WTF – Portable Red Banks Conservation Park (near Burra)

Marcus (ex VK3TST) also headed out portable, but took a different slant on things. His intention was to go QRP phone from the get go, but to build a bigger than usual station. He also made the decision not to stay up, and admits that probably hurt his score, a lot, 83 points were gained in the hour before 6am.

Marcus’ Score was:

[table “” not found /]

His radios included a Yaesu FT-817 (not the ND) and a Yaesu FT-857D.

Antennas: 80/40 fan dipole, 20/15 vertical, 20m sloping yagi (supposedly pointing west), 160m EFHW. As far as antennas went, the poor attempt at a sloping wire yagi was full of fail. It must have been so close to the ground that it turned into an inverted-V. Marcus is thinking of making a 20/15 moxon for next time.

He also indicated that the highlight of his contest was a 160m contact with VK2IO, both portable in parks running QRP! A distance of roughly 1100km.

The ability to run a second radio was thanks to VK5QI who loaned him a 100A AGM battery. The rest of the station (817 & laptop) coped with 2x 12Ah SLAs a few Li-Ion pack to top up the batteries and 10+18W solar system. The 857 was the only thing hooked up to the AGM battery.

Mark VK5QI – Home Station

Mark decided to try out his new antennas and amplifier to see how he went. His tally was

[table “” not found /]

Mark commented that he was surprised:

  • That I could actually work people on 160/80m. The long-wire does actually seem to work! (Now to find a SG-235…)
  • The beam wasn’t that useful on 20m. I kept having to swing it around between VK6 and VK1/2/3/4, which got a bit annoying.
  • 400W certainly makes it easy to be heard – If I could hear someone, I could work them!

Peter VK5KX – Home Station

Peter admits his was a token effort – but he had fun (which is the main thing!)

[table “” not found /]

Overall, AREG was very well represented on the bands, and most of all everyone had fun!

See you next year on the Remembrance Day Contest!

IARU HF Championship Contest – THIS WEEKEND

Posted on by

The IARU Contest will be conducted this weekend on HF (non-WARC) bands from 10pm EST Saturday 9 July to 10pm EST Sunday 10 July 2016.

This is a good opportunity to test out the bands (particularly the lower ones) and get more more DX into your log.  The contest details can be found at http://www.arrl.org/iaru-hf-championship

The exchange is 59 and your ITU zone (e.g. VK6=58, VK8 and VK4 = 55 and VK2, VK3, VK5 and VK7 are in zone 59

The Wireless Institute of Australia will run a HQ station using the callsign VK5WIA.

The SSB station (80-10M) will be operated by members of the Amateur Radio Experimenters Group using Chris VK5CP’s station near Mannum South Australia.  We also expect to have a separate CW station coordinated by Chris VK3QB.

AREG Participation in the SPDX RTTY Contest: Report

CQ SPDX TEST DE VK5ARG VK5ARG KK

The AREG team tried something new on Sunday April 24th 2016, operating portable from the Morialta Conservation Park just east of Adelaide hexbeamin the Polish Radiovideography Club’s SPDX RTTY contest . A lot of fun was had by those members who operated and visited us during the activation. 29 valid contacts were made including 5 out of 17 Polish provinces. Andy VK5AKH provided the bulk of the station equipment and was assisted by Grant VK5GR, Dennis VK5FDEN, Gary VK5FGRY and Mark VK5QI in setting up the station in the early afternoon.

By the time we were ready to go, long path Europe was already open, and the first station we called answered on the first try. We were running an IC7600 at about 90W FSK power with the HexBeam and the Fl-Digi software for RTTY. We also experimented with the GRITTY software which has some advanced decoding capabilities.

40m Loop Antenna

40m-loop-vk5sfaSteve VK5SFA also brought along his new 40m magnetic loop antenna for us to experiment with. We were very impressed with it’s noise performance and efficiency for such a small antenna. While we were working 20m RTTY long path EU, Matt VK5ZM, Gary VK5FGRY and Mark VK5QI experimented with the loop. Contacts on it were had across SE Australia, including 10W to 10W to Chris VK5CP who was portable in Parachilna in the Flinders Ranges.

(Stay tuned – a talk is planned at the next AREG meeting on these very unique antennas).

Contest Progressed

As the RTTY contest progressed, the team attempted 15m as well with limited success before returning to 20m to close out the EU LP opening.

We were then treated to the “AREG Catering Service” in the form of Sharon VK5FSAW who brought up baked potatoes and condiments, which were very welcome considering it was getting quite cold as the sun went down.

Finally we dropped down to 40m and put the loop to use on RTTY. We picked up a contact with the USA – after spending a while learning how to tune it! (It is only ~3-4kHz wide).

Who we worked

While we were not competitive we had a lot of fun working RTTY stations in Europe, and we are sure we helped a few polish stations with a continental multiplier. The stations we worked were:

This has certainly whetted our appetite to try another attempt at RTTY later in the year (perhaps the CQ WW or CQ WPX RTTY contests).

A big thank you to everyone who participated and in particular to Andy VK5AKH who brought his portable HF station.
