Several weeks ago, members of AREG headed out into the country side to try an experiment that many had wanted to do for many years – bounce a signal off the moon. With the help of Peter VK5PJ who has the necessary high power permits, we were able to achieve just that!

The team involved will take people through the events of that weekend and share what we learned about EME procedures, RadHaz management, JT65A and what it takes to send a radio signal over a half a million km journey to the moon and back.


Meeting Date and Time

NOTE This month’s AREG meeting is occurring one week early on the 2nd Friday of the month, so as to avoid clashing with the John Moyle Memorial Field Day Contest the following weekend. The hall will open at 7.15pm and the meeting will commence at 7.45pm sharp with a short AREG business meeting. The guest presenters will start by ~8pm. The presentation will be followed by coffee and cake and an opportunity to discuss EME with those who were there.

AREG meets at the Fulham Community Centre, Phelps Court, Fulham (formerly known as the Reedbeds Community Centre).

Visitors are most welcome!

Getting Started on 630m (476kHz) – 7.45pm February 15th

The next meeting of the Amateur Radio Experimenters Group will be held on Friday 15th of February. This month we have Andrew VK5CV as guest presenter who will introduce the world of the 630m band on 476kHz. Andrew has been an active experimenter on this band for some time in Adelaide and is a fountain of knowledge on how to put a signal on air on this band, even from a suburban block.

Visitors are most welcome!

Advanced Notice – March & April Meetings – New Dates!

The Amateur Radio Experimenters Group also wishes to advice that we have changed the dates for our March and April meetings.

  • The March meeting will now be held on the 8th of March (2nd Friday) so as to avoid clashes with the team setting up for the John Moyle Field Day. The topic for this meeting should be confirmed shortly.
  • The April meeting will now be held on the 12th of April (again the 2nd Friday) so as to avoid clashing with Easter Good Friday. This meeting will hear from David VK5DGR on his work to develop FreeDV2020 – a new high quality audio version of his FreeDV HF digital voice transmission mode that uses roughly the same bandwidth as FreeDV 1600

Stay tuned for other special events that are also planned in the coming months! More information will be published on these as they are confirmed!

HNY 2019: January Meeting – HF Remote SDRs & AREG’s Remote Site Project

Firstly, Happy New Year 2019 to everyone. This year promises to be yet another action packed fun filled series of events brought to you by the members of the Amateur Radio Experimenters Group.

Next Meeting – Friday January 18th – 7.45pm

The next meeting of the Amateur Radio Experimenters Group Inc will be held on Friday the 18th of this month. The topic of the evening will start with a short introduction to the world of remote HF SDR receivers and how to access them.

It will then be followed by a workshop event looking at the original AREG project intended to setup and host one of these systems here in Adelaide. The original project was plagued with problems, most notably getting an internet link out to the site some 40km away from VK5RWN. In the end we weren’t successful in getting the microwave link to be stable. The secondary issue of local site noise at the receive site was never even addressed because the internet feed couldn’t be resolved.

Now that 2019 is here, and the opportunity of a new site has presented itself (that solves the internet access issue), the club is looking for members to form a new team to try and complete the project. The second half of the meeting this month will explore what tasks need to be done to make this a reality and we will be looking for volunteers to put their hands up to help

Visitors are always welcome! The club meets at the Fulham Community Centre, Phelps Crt, Fulham from 7.45pm. The presentation starts at 8.00pm and will be followed by coffee and cake before a formal business meeting.

We look forward to seeing you all there!

Following the meeting, a come and try Fox Hunting event will be held the following day (Saturday November 10th) at 1pm in the South East corner of the Adelaide Parklands, off Beaumont Rd near the Greenhill Road end. The come and try day will allow those without gear to come and see how to get started and to try their hands at some pedestrian direction finding using equipment such as Bryan’s sniffer receivers.

Visitors are most welcome at both events. If you have ever been curious or just want to come for a day in the park on Saturday then drop on by – we would love to see you and introduce you to the fascinating world of radio direction finding!

AREG IRLP & DSTAR Gateways Back in time for JOTA

 

After several months of disruptions due to lightning and HDD failures at both the VK5RSB IRLP node and the VK5RWN DSTAR Gateway AREG is pleased to announce that we have been able to restore both services in time for this weekend’s Jamboree on the Air for the Scouting and Guiding communities.


VK5RSB Internet Relay Linking Project Node #6214

The IRLP Node 6214 will be available for use by users supporting JOTA this weekend, 20, 21 October. The node can be accessed via the VK5RSB 70cm repeater on 439.900 (-5MHz) using a 91.5Hz CTCSS access tone.

In the support for JOTA, the prefix access code has been removed for this weekend, thus allowing free access to the node.

Therefore to access remote IRLP nodes,

  • dial in the 4 digit DTMF node address of the remote node.
  • to disconnect the IRLP connection, just dial “73” a the end of the QSO.

AREG wishes the JOTA teams and other users, to have fun with contacts via the IRLP Node 6214.


VK5RWN DSTAR Gateway Restored for the 2m/70cm repeaters

The VK5RWN D-Star repeater and gateway is also now fully functional after its computer rebuild. It’s new computer has been installed and the gateway configuration is now complete using the new ICOM G3 software.

Currently the configuration is;

  • Port C, the 2m port, is unlinked and available for general use or user linking to reflectors and gateways etc (147.0375 +600kHz)
  • Port B, the 70cm port, is permanently linked to Reflector REF023C and will output any activity on this reflector and will repeat local RF activity on the 70cm channel into the reflector network. (438.400 -5.4MHz)

NOTE: Port B may be disconnected from the link to REF023C with the unlink command, “^^^^^^^U” , (the ^ represents spaces)  then it may be connected by the user to another address.

VK5RWN activity is now being reported to various Dashboards,

D-Star network access seems to fully functional. Ben VK5BB reports that he has tested linking to several reflectors through the local gateway as well as connecting directly to VK5RWN via his JumboSpot hot spot successfully.

So, any members or DSTAR users in Adelaide who have an interest in D-Star, have D-star capable radios and are registered on the D-Star system, please give VK5RWN a try out and feedback will be appreciated please?

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.
