Next Meeting: Parks ‘n’ Peaks Operations with Paul VK5PAS

Posted on by

AREG is always looking for avenues to encourage amateurs out into the field to operate their stations. One of the unique ways to do this is to go and operate from a conservation park. Several awards systems have been established to promote this type of portable operation. These have been very effective in stimulating activity on the HF bands domestically particularly during daylight hours on 20 and 40m.

There are various forms of these awards including Summits On The Air, World Wide Flora and Fauna and other National Parks awards both in Australia and abroad. Paul VK5PAS has been a major champion of this type of operation and in particular is the founder of the VK5 National & Conservation Parks Award.

Sample VK5 Parks Award Certificate

At AREG’s next meeting on Friday June 17th, Paul VK5PAS will give a presentation on the Parks ‘N’ Peaks movement and the VK5 award in particular.

Everyone is most welcome to attend. The meeting will be held at:

Reedbeds Community Hall
Phelps Crt, Fulham

The doors will open at 7.45pm and the presentation will get underway at 8.00pm sharp.

After the meeting a short debrief will be given on the outcomes from the River Paddling Marathon that many AREG members are involved with this weekend.

Log Book Of The World

In addition to Parks n Peaks, Paul is now able to assist with the certification process for LogBook of the World. We hope to hear more about how to become registered for LOTW from Paul during the meeting as well.

Next Meeting: Transmitting Magnetic Loop Antennas for 160-40m

Posted on by

The AREG is pleased to announce that our guest speakers for our next regular monthly meeting will be Steve Adler VK5SFA, Leigh Turner VK5KLT and Paul Lawson VK5SL. They will be talking about their work on Transmitting Magnetic Loop Antennas for the lower HF bands including both the theory and practical aspects of their operation and construction.

VK5SFA 160-75m Transmitting Magnetic Loop Antenna

Steve has been using one very successfully on 160m and was kind enough to loan the AREG SPDX RTTY contest team his 40m one for use up at Morialta this past weekend.

These are fascinating antennas in the way they work and in the way they perform. Their noise immunity is something in particular to consider in urban environments where amateurs are space and electrically environmentally challenged.

Full details of how to build these antennas and the theory behind them are available via Steve VK5SFA’s website.

When and Where?

You can meet Steve and the team who designed and built them in person at our next meeting on Friday May 20th, starting at 7.45pm (for an 8.00pm start). You can find details of where the AREG meet on the contacts page.

Visitors are most welcome to come along! A short business meeting will be held after the presentation.

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.

Next Meeting 15th April: HF Communications for New (and old) Hands

Posted on by

The next monthly AREG meeting is coming up on Friday April 15th, starting at 8.00pm.

Our presenters for the evening are Chris VK5SA and Andrew VK5AKH. They will jointly be talking about HF communications, giving insights into how the HF bands work, and how to get the most out of them from your everyday station.

April-2016

Africa in 1997 – Chris will talk to this

Chris VK5SA’s segment is primarily targeted at for Foundation members who are struggling to understand HF propagation, and also Z-calls who have finally embraced these frequencies 🙂 He originally gave it in Kenya nearly 20 years ago for native African NGO radio operators who needed to be shown what frequencies and antennas did what.

Grant VK5GR (ex VK5ZWI’s) new shiny HF Antenna (now how to I talk to someone on these bands?)

Chris will explaining what you need to do to reliable HF communications and relate how this was explained for an operator sitting by his ‘phone in Cape Town.

Andy VK5AKH will follow that with a practical guide to getting started with HF operation. Topics covered will include what band, what mode, what time and for those lucky enough to be putting up a new hex beams what azimuth!

Andy will also discuss some tools to make life easier with identifying band/Dx activity, so that you can make the most of your work/ham radio/life balance.

Meeting Location

Our meetings are held at the:

Reedbeds Community Hall,
Phelps Crt
Fulham

Doors open at 7.45pm with the meeting starting at 8.00pm

Visitors are always welcome, so this month, in particular if you are one of the newly licensed foundation calls, why not drop in and meet the Amateur Radio Experimenters Group!

AREG develops kit which allows real time display of Antenna radiation pattern

Posted on by

The Amateur Radio Experimenters Group, one of  Adelaide’s leading Amateur Radio groups is pleased to advise that after months of research and experiments at a secret location, it has developed and perfected a process whereby the radiation pattern of any HF antenna can be displayed visually, full size in real time.RfPatternSmoke-AprilFools

The kit includes a canister of particles which are sensitive to E and H field radiation. The particles are suspended in harmless nitrogen gas which, once released near an antenna will align to show you the radiation pattern of that antenna whilst it is transmitting. When the particles are charged by the E and H field radiation they become opaque, arranging themselves along the lines of maximum intensity of the emitted electromagnetic field. The end result is a real time ‘Smith Chart’ like representation of the Antenna radiation pattern.

The deluxe version of the kit uses a laser, guided by a PC controlled mirror arrangement, to display a grid pattern for calibration purposes, which will allow you to take a photograph for storage and future analysis.

A patent application has been prepared for lodgement, after which time the proposal will be presented at the April Monthly meeting. Kits will be funded through the “StartKicking” process in due course.
