AREG October Meeting: QRP Portable & SOTA Operation – THIS FRIDAY

The next AREG meeting will be held this coming Friday at our clubrooms at the Fulham Community Centre. Doors will open at 7.15pm.

Our presenter this month is Marcus VK3TST/VK5WTF who will discuss “the peaks and valleys of QRP portable, from where to go, to how to be heard, and the equipment you need to get a signal out.” Marcus, who was licensed as a teenager in 1994 is always trying to do more with less. He will talk about the basics of antennas he uses and his experiences hiking with amateur radio in both Australia and Japan.

 

The meeting presentation will commence at 7.45pm ACDT and will also be streamed live for members on Zoom (that is 7.15pm QST or 8.15pm AEDT for our interstate members). While we wont be offering a live Youtube stream this month, we do hope to post a recording of the presentation after the event on HamRadioDX.

The presentation will be followed by a general business meeting. All members are encouraged to attend either in person at the hall or via Zoom if you are remote.


To find us in person, the meeting will be held at the Fulham Community Centre, Phelps Court, Fulham SA. See you there!

3D Printing Introduction – Youtube LiveStream Friday 17th 7.45pm ACST

AREG is pleased to confirm that our next meeting will be streamed live on Youtube via the HamRadioDX Channel!

The broadcast will start on Friday 17th September:

  • 7.45pm ACST
  • 8:15pm AEST
  • 1015 UTC

 


The presentation by Scott VK5TST will provide an introduction to filament based 3D printing. While the technology is large, and there are many ways to use and enjoy it, this is based on one person’s experiences. I approached 3D printing as getting a new tool to help with other hobbies, rather than my hobby being build and development of the printer.

The presentation will discuss the technology, the process, equipment (software, printer and consumables) with some tips on how to get started. Not to mention a few lessons over a year or so of playing with the hobby.


The Amateur Radio Experimenters Group will be hosting the presentation live at our clubrooms at the same time, Phelps Court, Fulham. Doors will be open from 7.15pm. COVID Safe protocols will need to be observed – face masks will need to be worn and COVID Check in will be mandatorty.

Remote AREG members will be able to interact with the meeting via our Zoom link.

August Meeting: Amateur Radio Contesting with VK5ARG

VK5ARG: Tarlee Contest Site – Remembrance Day Contest 2021

The next meeting of the Amateur Radio Experimenter’s Group will be held this coming Friday, 20th August. The topic will be Amateur Radio Contesting with VK5ARG. During the meeting we will explain the basics of Amateur Radio Contesting and how we apply them during “Contest Month” up at our remote site west of Tarlee.

The aim will be to demystify how to get involved with contesting and explain the basics. We will also talk a bit about contest strategy, band awareness and operating styles, so you can get a feel for how to make contacts in a contest environment. After the initial presentation, there will be time for Q&A.

For anyone who would like to get involved in Contest Month during September/October for the first time, know that we will be working to introduce newbies at the event with each new operator having a mentor to help them get into the swing of things!

Michael VK5ZRN – First time contester – Remembrance Day Contest 2021 @ VK5ARG

The presentation this Friday night will start at 7.45pm. Doors open at 7.15pm and the venue will be the Fulham Community Hall, Phelps Court, Fulham! Visitors are welcome – see you there!


AREG Members note: the meeting will be simulcast on Zoom for members who cant be there in person, but there will be no YouTube stream this month. We will be observing the current COVID restrictions at the hall as well and will ask everyone in attendance to wear a mask in accordance with current health guidelines. Check in at the door will be mandatory. If you are unwell, please stay home and join the proceedings via Zoom!

Medium Wave Digital Radio Mondiale Broadcasting Trial: AREG Members Listening

There is a very un-publicised Digital Radio Mondiale (DRM) trial on air in Australia at the moment. The trial is on 747kHz from a transmitter site in Wangaratta, Victoria and the program is ABC Radio National.

Youtube video from “digitalmediafan” 

The signal does become decodable at times during the early evening however; there is co-channel interference coming in from MW AM transmitters on 747kHz in Toowoomba, Hobart and Esperance to contend with along with selective fading in the pass-band.

More information on the DRM format can be found here: https://www.drm.org/

Steve VK5SFA has been experimenting with decoding the signal and has had some success using the following information and links:

  • How to install the decoding software. (HERE)
  • Source of the required Dream V2.2.x software (HERE)
  • And the missing dll file here:  (HERE)

He also suggests a directional antenna such as a magnetic loop might be of some benefit. Steve has used his Flex Radio as well as an Airspy HF+ Discovery SDR receiver with some success. Experimenters should also remember to use a digital USB mode (no audio EQ) and make the RX filter wide enough to fit the whole digital spectrum when trying to decode the signal.  (Note the centre carrier frequency is 747kHz +/- the signal BW)

Have FUN experimenting!

Project Horus LIVE: Pico-Balloon Flight in progress – heading for VK3!

UPDATE: This balloon has now burst and landed 60k to the east of Bendigo. Thanks to everyone for tracking! The following callsigns were recorded as contributing telemetry:
VK2PNH, VK3AH, VK3BQ, VK3DA, VK3DNS, VK3EEK, VK3FUR, VK3IK, VK3JED, VK3JL, VK3JUG, VK3MB, VK3OF, VK3OHM, VK3TNU, VK3UKW, VK3YD, VK5BRL, VK5HS, VK5IS, VK5LJG, VK5PE, VK5QI, VK5TRM
Here’s some entertainment for the VK3s & Southern VK2s/VK1s this weekend – I’ve sent another pico balloon (30 grams) careening towards the east, currently doing >280 kph!
If it ends up floating as intended (and it might not, these things are finicky…) then it should keep heading past Melbourne and off towards the east coast.
Tracking of the flight is available here: https://tracker.habhub.org/…
It’s transmitting the Project Horus ‘Horus Binary’ 4FSK mode on 434.200 MHz (tune to 434.199 MHz USB), and can be decoded using the Horus-GUI software: https://github.com/…/1.1-Horus-GUI-Reception-Guide…
