Annual General Meeting – Friday August 18th @ 7.45pm

Featured

The next meeting of the Amateur Radio Experimenters Group will be held on Friday August 18th, at the Reedbeds Community Hall, Fulham.

The doors will open at 7.45pm for an 8.00pm start.

To start the proceedings, the committee will recap the year’s events before moving into the reports and then the business of the meeting. All positions will be declared vacant and nominations will be sought.

The outgoing committee wishes to thank in particular Scott VK5TST and Ben VK5BB who have both indicated that they wish to step down in 2017/18. We look forward to new enthusiastic members joining the committee and continuing to drive the club forward as we enter the club’s 20th year!

A general meeting will follow the AGM, with a general coffee and cake discussion to be held afterwards. if you have a project you have been working on why not bring it along and show it off during the coffee discussions.

AREG in the 2017 Trans Tasman Low Band Challenge

UPDATE: The results have been published – VK5ARG came second in our multi-op division! Well done team!


On Saturday July 15th, AREG members VK5GR, VK5QI, VK5MTM and VK5IX gathered together with Steve VK5SFA at his QTH to participate in the Trans Tasman Low Band Challenge Contest  as VK5ARG. Originally planned as a portable operation, the portable activity was cancelled at the last minute due to a critical piece of equipment not being ready (the new club portable 160m loop antenna). The change of venue was deemed a fantastic outcome by all who participated as outside temperatures plummeted into the low single digits. Steve and his wife were fantastic hosts and we were able to operate the full 6 hours in luxurious conditions.

The station consisted of Steve’s IC7700 running either 80 or 160m on the Magnetic Loop antenna, while Grant’s K3 ran on 160/80/40m either on the 40m rotatable dipole or the 80/160m trapped dipole, depending on the combination we selected. We had hoped to also have a IC7000 dedicated to 40m, however the RFI from the MagLoop (one of their drawbacks it seems) was severe and rendered the second 40m station unusable. Something to learn from there when using the loop in later contests.

Four of us operated whilst one was there for moral support (guess which one (chuckle)). Activity came in bursts although there were times when the pickings were very slim and we called for many minutes without a bite. 40m was completely dead after dark, but not for want of propagation. When we did find someone (VK4HH) they were easily workable. It seems that 7MHz is forgotten in this contest after dark – perhaps unwisely so.

We also ran CW (having two gun CW operators helped) which filled in the dead patches  calling on SSB. We were going to try RTTY, but were still configuring the MicroHam keyer and hadn’t cracked the code of how to make it run with MMTTY and N1MM in time for the contest.

A highlight was the a number of contacts made with New Zealand stations this year. ZL contacts were achieved on 40, 80 and 160m, although on 160m it was often hard going.

The Transmitting Magnetic Loop Antenna we used for this contest on 80/160m

All up we made 211 contacts. Here is the map of where we worked

Thanks to everyone who participated from AREG and thanks also to all of the stations across VK/ZL who participated in this unique contest!

July General Meeting: Introduction to Antenna Modelling

The next AREG meeting will be held on Friday 21st July, starting at 7.45pm at the Reedbeds Community Centre, Fulham.

We are pleased to announce that the speaker for the July meeting will be Paul Lawson VK5SL. Paul will be introducing you to the basics of Antenna Modelling, and will demonstrate how to get started using the 4NEC2 program to examine antenna performance (4NEC2 is freely available on the Internet). He will take 3 of the antennas that Chris VK5SA described in his wire antennas for beginners talk a few months ago and show how you can visualize their radiation patterns and what their characteristics are on various frequencies.

In particular, Paul will show you how to model a basic dipole, a Windom (OCF Dipole) and an inverted V antenna, explaining how to define these in the software, what the components in the software do and how to set them to produce useful models of how the antenna is performing. This will be a great simple introduction to the topic of antenna modelling.

For those who then want to delve deeper, Paul has agreed later in the year to run a tech night where more complex antenna modelling will be examined for those who want to take it further.

We hope to see you at the club on Friday July 21st. Doors open at 7.45pm with the presentation getting underway at 8.00pm sharp.

AREG Next Meeting: Introducing LF and MF by Doc VK5BUG – 16th June

The next meeting of the Amateur Radio Experimenters Group Inc will be held on Friday June 16th, starting from 7.45pm at the Reedbeds Community Hall, Phelps Crt, Fulham.

The topic for this evening will be introducing LF and MF communications techniques, presented by David (Doc) Wescombe-Downs, VK5BUG. Doc is a pre-eminant authority on everything LF and MF in Australia, and is one of the modern pioneering amateur experimenters of these bands today. If you have ever wondered how on earth you can start using the 630 and 2200m bands from home, then come on down and hear Doc talk about whats possible.

Doc will also have a limited number of his books available to purchase for those taken with enough interest in the subject.

LowBand Book Promotion Flyer

After the presentation, there will be a short business meeting plus time to socialize and hear more about what happened at this year’s River Paddling Marathon (being run over the June long weekend and being supported by AREG and RRC).

You will find the clubrooms at the following address! We hope to see you there!

AREG Beginners Series: Introducing HF Wire Antennas – April 21st

Next AREG Meeting: Friday April 21st – 7.45pm

Continuing with our beginners series presentations this year, this month we have Chris VK5SA who will talk us through the basics of the simple wire HF antenna. He will explain the characteristics of a set of simple to build yet effective HF antennas that anyone can make, often for less than $100 worth of materials. He will show you the merits and limitations of several of them, including:

  • Basic Dipoles
  • Offset Centre Fed Dipole
  • Inverted V
  • Fan Dipole
  • Terminated Folded Dipole

Samples of how to build many of these will also be on hand for people to take a look at.

Meeting Time & Location

The meeting will be held at the Reedbeds Community Centre, located off of Phelps Court, in Fulham. The clubrooms will open at 7.45pm with the meeting to commence at 8.00pm sharp.

Tea, coffee and cake will be available for a small donation after the presentation. Following that, the monthly business meeting will be held.

As always, AREG meetings are open to everyone, so if you are interested in starting out on HF, then this is a great opportunity to hear about some simple antennas to get you underway!

Australian Contesting Technical College – Friday 19th May 3-5pm

Have you ever wanted to learn about contesting but didn’t know where to start? Did you ever want to learn the secrets of how the big stations earn their scores? Well now is your chance!

In May, AREG will be hosting a special event immediately prior to the WIA AGM in Adelaide. On Friday 19th at 3:00pm, the club proudly invites you to attend the “Australian Contesting Technical College”, presented by Trent Sampson VK4TS. The venue will be the clubrooms, located at the Reedbeds Community Hall, in Fulham (5 minutes from the airport for those around Australia flying in who would like to attend). This once in a lifetime event is open to anyone with an interest in Amateur Radio Contesting.

Trent VK4TS with Alan VK4SN

Trent Sampson VK4TS is the Contest Columnist for AR magazine and a member of the Lambda Contest Group who operate under the Callsign VK4KW and holds many records in Multi Operator categories in SSB RTTY and CW.

During the 2 hour session, Trent will discuss setting up a modern contest station for SO2R (SIngle Operator 2 Radios) operation as well as Multi operator station considerations, including equipment selection, interfacing, and antenna selection.

The Antenna selection part will include a real life appraisal of a contest location (likely to be one of the AREG sites) and how well it will work using High-Frequency Terrain propagation analysis.

When considering software, Trent will discuss examples of how to use the most popular software and the lessons learned from it.

Topics Covered will include:

  • Multi Operator Stations,
  • SO2R Operation
  • Filtering; Bandpass and Coax Stub,
  • Antenna selection Software usage,
  • N1MM with examples of SSB RTTY and CW.

So organise your Rostered Day Off now, or arrange to get into Adelaide a little bit earlier that day if travelling from interstate and make your way to the Amateur Radio Experimenters Group clubrooms for this once off special event!

AREG Members note: this is in addition to the May Meeting, the hall will close between 5:30 and 7:30 then reopen for the normal monthly meeting. As always visitors are welcome.

AREG March Meeting: Space Weather and Ionospheric Prediction

The Amateur Radio Experimenters Group is proud to announce our guest lecturer for our March general meeting is David Neudegg, Principal Space & Radio Scientist, Space Weather Services (Australian Federal Govt). David formerly worked for the Ionospheric Prediction Service before that agency was reconstituted inside of the Bureau of Meteorology.

David brings a wealth of knowledge about the ionosphere and how it works and will provide a fascinating insight into how it’s behavioral predictions relate to people’s real world experiences when using HF radio communications.

Meeting Details

The meeting will be held on Friday March 17th at the Reedbeds Community Centre, off Phelps Court in Fulham. Doors will open at 7.45pm, with the presentation beginning at 8.00pm.

Visitors are most welcome! We hope to see you there!

 

Next Meeting: How to track Project Horus Balloons!

The next meeting of the Amateur Radio Experimenters Group will be held on Friday February 17th, starting at 7.45pm.

This month, Matthew VK5ZM will be showing everyone how they can get involved in telemetry tracking during a Project Horus balloon flight. Matt will explain the basic equipment any amateur can use to receive and decode the RTTY telemetry from the balloon.He will also discuss the value to the project team you can bring by taking the time to decode the telemetry for us, as every frame collected and relayed to the Internet is added to the data being used by the recovery teams seeking to retrieve the payloads at the end of every flight.

The next launch that you can then try out your new skills is the following weekend, so this is very timely! Horus 43 which is being flown for Rostrevor College is planned to launch Sunday February 26th at 10.00am.


The presentation will be followed by a business meeting. Visitors are most welcome to attend! Come on down and find out this and many other aspects of the activities being undertaken by the AREG!

You will find the club at the Reedbeds Community Centre, off Phelps Crt, Fulham.
