VK5RSB 70cm Repeater Service

14 May 2020

Note: VK5RSB is still on air – but its tail is now VERY short. We will rectify the problem with the tail as soon as we can.

Further update regarding the VK5RSB operations.

In the exuberance of the repeater service crew to see VK5RSB running with the AREG repeater controller, the repeater’s operations in conjunction with access to the IRLP network was overlooked.

IRLP node 6214, is accessed via the VK5RSB 70cm repeater.

The IRLP network managers do not like local repeaters sending “Roger Beeps” and repeater idents out into the IRLP system. This is because such idents etc will be transmitted elsewhere in the world, which is certainly not appropriate!

Under the previous setup of the VK5RSB 70cm repeater, the CW ID was generated within the Motorola Quantar but was transmitted without CTCSS, therefore not keying the IRLP unit and not being transmitted over the IRLP system, which needs CTCSS to be keyed for operation.

Therefore, with this in consideration, the “Roger Beep” has been turned off and the repeater “Tail” has been shortened to 1 second.

The Voice indent will remain for the short term, as any ident generated by the AREG repeater controller will still be transmitted with CTCSS.

The current final solution to this oversight, is to remove the AREG repeater controller and reset the Quantar code plug as had been previously.

The repeater service crew are sorry for any issues that came about from this exuberance.

We trust that all will continue to enjoy and take advantage of the VK5RSB repeaters.

Just a quick update on the VK5RSB 70cm repeater.

This morning Paul VK5BX, myself Ben VK5BB and the Covid 19 Supervisor, Alesia (harmonic) attended at the VK5RSB site.

Purpose of the visit was to,

  • change over the VK5RSB 70cm repeater Motorola Quantar,
  • one out, one in, setup for operation with the AREG repeater controller,
  • re-fit the AREG repeater controller for the 70cm repeater,
  • check the site installation operation.

The equipment change over was without issue and the operation is successful with the new configuration of the repeater working well.

Noticeable operational changes,

  • 5 second long tail
  • a “Roger beep”,
  • the time out timer resets on the “Roger beep” (so no need to wait for the tail to drop)
  • voice ID
  • on long overs, a low level CW ID will play over top of the QSO.

Many thanks must go to Paul for his perseverance and time in setting up the replacement Quantar and mating it with the AREG repeater controller.

Reports and feedback would be much appreciated please.

AREG Nets: On Line and On Air!

To help keep our members connected during this time of social distancing and COVID-19, the club is moving to increase the amount of on air contact opportunities. We are planning on holding an alternating on air net one week and a Zoom round-table chat on the alternate weeks.

The next event will be held this coming Friday, 8th May. Starting at 7.30pm it will be held on the club’s VK5RSB repeater 439.900 which will be linked to the IRLP network via node 6214 to reflector 9558 (which is also linked to the EchoLink node *VK3JED*

This will help to keep our interstate members connected too!

The following dates will also have an on air net:

  • May 22nd
  • June 5th

Visitor check-ins are most welcome on the on air nets. The net control station is VK5ARG.


In between the on air weeks, there will be a separate video round table using Zoom Meeting online for members only.

The club just held one of these which was hugely successful as everyone got to see, hear and participate in the free discussions that en-shewed. Members will be provided details of the Zoom logins for each of these on our internal mailing list.

Currently the next scheduled Zoom round table for members is May 29th, also starting at 7.30pm.

Details of our monthly meeting for this month are in a separate post.

We hope to see you all on the air!

AREG Lecture: April 2020 – Online !

This month the AREG will be taking it’s monthly lecture Online due to COVID-19.  Dave VK5FDAN will be talking to us about Solar Cycle 25 and what we can expect HF to do as we come out of the current Solar Minimum.

While we experiment with various Online meeting platforms we have elected to limit our initial lectures to members only.   I’m sure that once we have found our feet and have ironed out the bugs in our chosen system we can once again look at opening our doors to other interested Amateurs or groups in some form.

I know within our group we’ve wanted to look at online meetings and lectures since we have both international and interstate members, but for reasons it’s never happened.  Times are certainly changing and the impetuous to do so is now.  So please continue to watch this space…

From everyone within the AREG we wish you all the best, please maintain your social distance and stay safe !

USA Exams planned for Adelaide April 4th: CANCELLED / POSTPONED

UPDATE: March 22nd 2020 – Due to the ongoing COVID-19 pandemic and the South Australian government now restricting interstate travel (requiring forced isolation for those arriving in the state), the VEA team has regrettably had to cancel the planned FCC exam session for April 4th in Adelaide.

VEA and AREG hope to reschedule this opportunity for later in the year once the restrictions have been lifted.

Next AREG Meeting (March) – Cancelled !

The next meeting of the Amateur Radio Experimenters Group has been cancelled due to concerns regarding the COVID-19 virus.  Dave VK5FDAN’s talk on the ionosphere will instead be held over until our April meeting, please continue to check our website for details closer to the date.
In lieu of our usual monthly meeting members and friends of the AREG are encouraged to join us on VK5RSB 70cm at our regular meeting time for a Net and a chance to catch up for a chin wag.
Again our apologies to all members and friends for the short notice of cancelling this months meeting, I’m hoping to catch many of you on VK5RSB 70cm Friday night at 8pm.

Next AREG Meeting POSTPONED: Hello Solar Cycle 25! –

Due to the cancellation of our March meeting, we are now hoping we can bring this topic to members in April. Stay tuned for further details

Always of intense interest to Radio Amateurs is what is going to happen to the ionosphere. More recently, the big question on everyone’s lips has been, when is Solar Cycle 25 going to get underway and how strong (or weak) is it going to be.

AREG is pleased to announce that we have a preeminent expert in this field coming to speak at our Friday 20th of March general meeting. Dr David Neudegg (VK5FDAN) from the Defence Science & Technology Group will give us a radio amateur perspective on what is happening with Solar Cycle 25.

The meeting will be held at the Fulham Community Centre, off Phelps Court in Fulham. The meeting will start at 7.45pm. Doors open from 7.15pm. Visitors are most welcome to join us!

We hope to see you there!

Marathon Canoe Club: River Paddling Marathon 2020 – call for radio volunteers!

The River Paddling Marathon 200 event staged by the Marathon Canoe Club of SA will again be running over the June long weekend from Berri to Morgan in South Australia’s Riverland. Staged over 3 days from June 6-8, this event will see over 100 competitors brave the winter cold to paddle the mighty Murray River downstream for 200km.

Once again, the Amateur Radio Experimenters Group in conjunction with the Riverland Radio Club, is supporting this major community event with a safety communications radio network. Communications is provided via a combination of Amateur and Commercial VHF/UHF radio networks. The radio team operates 20 check points, including 3 locks, 9 starting lines, 3 finish lines, the event command post and provides VHF command and APRS tracking of 4 safety boats plus the event medics. This is all delivered via a 2m/70cm FM network using a combination of local and portable repeater systems deployed specifically for this event.

Would you like to get involved?

To cover all of the checkpoints and roles, the group needs a small army of volunteers. Members from both AREG and RRC have been the backbone of the event now for over 5 years. This year, we would love to broaden the engagement further. If you are a member of any of the local radio clubs, WICEN SA, WICEN VIC or just an individual with 2m/70cm mobile capabilities and you would like to get involved, please contact us via vk5arg@areg.org.au to express your interest. Registrations are open until the end of March 2020.

What do you need to participate?

We keep the check point requirements simple. Each checkpoint is open for ~3-4 hours and mostly operators are only rostered on for one checkpoint a day.

For most checkpoints a 2WD vehicle and a 25W or higher 2m mobile radio with a car mounted antenna is usually sufficient to reach the comms network. 70cm is used in a limited number of check points too. Minimum teams of 2 are preferred, one for spotting and one for manning the radio. If you wish to participate as an individual we can pair you up with one of the other operators for the day.

If you have never participated in the event before, there will be a briefing night held in Adelaide several weeks before the event. If you are new to the event, our event planners will stage you with one of the more experienced operators to show you the ropes the first year.

Logistics Arrangements?

The Radio network participants are mostly based out of Kingston on Murray caravan park for the event and many come and stay for the three days. AREG provides financial assistance towards the cost of accommodation and one of the meals during the event. People usually arrive in the area Friday afternoon (and a small team gets to work that day installing the radios in the boats around 4.30pm at Waikerie). The event is over by 4pm on Monday afternoon leaving plenty of time to drive back to Adelaide.

If you cant come for the full three days, on the Monday in particular it has not been uncommon for people to come up just for the day from Adelaide. (Day 3 is centred near Morgan so is within easy reach).

So if a fun relaxing 3 days on the Murray River interests you please contact us via vk5arg@areg.org.au to express your interest! We would love to see more members of the Amateur Radio community getting involved and supporting this fantastic community event!
