WELCOME TO SARC
Serving the Northern Rivers of NSW
Members are reminded that club fees are now due. Details of payment options are here: https://sarc.org.au/membership/
The Club’s Committee and Committee Appointed Positions are now listed on the Committee page.
At a recent meeting it was decided to have a mini working bee on the morning of the club Committee Meetings. The clubrooms have a collection of “stuff” that needs to have a home or a storage location. Kickoff is around 10am or so, so please drop in and lend a hand.
The 70cm repeater at Mt Nardi on 438.675 MHz, 123 Hz tone is operational with an improved Tait repeater radio set. The 70cm Repeater at Parrots Nest is now offline as the repeater radio equipment has been removed and installed at Mt Nardi. The 70cm Repeater at Parrots Nest will not restart until a new repeater unit can be built and installed there.
DAWN PATROL CHANGES SOON: On Monday 5th October the Dawn Patrol will move to 7.117MHz. It will begin at 7am NSW daylight saving time which is 6am QLD time.
It’s up!
The club’s Sign is now fixed in place, thanks to Ross VK2ARD and Paul VK2AMT. Have a squiz when you’re passing!
The club sign’s frame is up, thanks to an informal working bee on the morning of Sunday 12th, before the Committee meeting. It’s now cemented in place and awaiting the sign’s attachment soon. Many thanks to all who helped. Andrew VK2XI’s experience as a fencing contractor came in handy, he had the holes dug in no time.
A bit of work at Parrots Nest
Above, at left is the new Tait TB8100 repeater for 70cm. Installed Saturday 4-7-26. To the right, Ross and Duncan work on installing it. Ross also gave the site a run over with the ride-on mower and Duncan and Ross also whipper-snipped the weeds.
A bit of work at the Clubrooms
Above is the new Cable Tray ready for the Coax Cables. There is a plate secured to the wall ready for cables. Many thanks to Tony VK2RI, for his help, it’s much appreciated. The cable from the HF wire antenna is aleady through the wall and connected. At right, Ross is busy trimming the tray and its supports to size. Running the thick Heliax coax through will be a job for another day.
Hey, there’s a new antenna up!
The old ZS6BKW has been replaced by one called a “Divorced Dipole”. Kindly supplied by Tony VK2RI. Erected by Tony and John VK2KJJ. Swept by the VNA of Andrew VK2XI. It’s working better than the old one. We’ll be interested in more reports from the Dawn Patrol.

SOME NET REPORTS FOR WEEK ENDING EPTEMBER 27, 2026
Dawn Patrol numbers for the week were 27.
Just a reminder, as of Monday April 6 the Dawn Patrol will shift time to 06:30 AEST as a result of the loss of Daylight Saving. Frequency remains 3.604Mhz
Monday September 28, 2026 Joni VK2ZJJ ran the net and was joined by Paul VK2AMT and Barry VK2VBG. There was another unidentified station not making it. It was a fairly lazy day for all. We all noticed a sudden change in the audio received from Parrots Nest 2m, the voices sounding sharper, as if a fair bit of bass had been removed. It’s been heard before.

Tuesday September 29, 2025. – The Diginet
Joining Paul VK2AMT as VK2SRC on 2 metres Parrots Nest was Barry VK2VBG and Joni VK2ZJJ. After a couple of brief overs I QSY’d to our 80m frequency of 3.590 MHz USB for another session with Olivia 8-500 on Fldigi.
First up before the net started was Fraser VK4FRZ who was testing on Olivia 8-250 with Arjun, VK4PAA, another member of the BARC, who was keen to join us on the net. Once we got under way, another BARC member, Dion VK4DKW, joined in as well as Jeff VK2NU, 3 VK4’s and 2 VK2’s!! Arjun’s signal was a bit low to me, S3 and -4 to -9 S/N which is close to Olivia’s limits, but it did improve later which resulted in 100% copy. Arjun was not heard by Dion VK4DKW. RF intrusion was causing problems for Arjun, hopefully they can be reduced, we’ve all experienced that at times. Many thanks to Fraser for encouraging his BARC mates to try Olivia mode on our net, it really is appreciated. Fraser told us about his coil making workshop, using 90mm PVC pipe with 30 turns of 0.6 to 0.8mm enamelled wire, resulting in 110uH. Arjun’s signal to me was close to 100% by then and he told us about activating all the POTA sites around Brisbane with handhelds. Jeff told us about 3D printing a Straight and Paddle CW keyer for future POTA events. He’s planning to visit some parks in the NSW Central West region. It was another excellent net, really a Techie Net, and many thanks to all who logged in told us about their radio projects.
Cheers from Paul VK2AMT
Wednesday September 30, 2026 70cm Mt Nardi. 6 stations joined this weeks Mt Nardi Net, Paul 2AMT, Jim 2YHP, Barry 2VBG, Dave 2DIZ, Joni 2ZJJ and myself 2XI. Barry was again operating mobile so he could access the repeater. Discussions included repairs to power supplies and Duncan’s road trip. It was great to have so many operators on the net. Why not join us next Wednesday at 8PM EDST on the Mt Nardi Repeater 438.675 MHz 123 tone and tell us what you think about anything you like. Everyone is welcome
de Andrew VK2XI
Thursday October 1, 2026 Woodburn 2 metres Joni VK2ZJJ ran this one as Paul VK2AMT was out with friends. Joni put out a few calls and was joined by Dave VK2ZDR for a few short overs but no-one else turned up, so it didn’t go for long.

Friday October 2, 2026. The After Dark Net. Dave (VK2ZDR) was the net controller, running under the club’s call-sign of VK2SRC. This week, we had Bruce 2VA, Jim 2YHP, Andrew 2XI, Peter 4PI then right at the end of the net, Rod 4OWN.
Again, we ran the net on our usual 80m band (3.604) but from next week onwards (for Summer), this net will be run on the 40mtr band (7.115) +/- a few k’s… {7.118} Depends on the night. The net time was mentioned: probably we will start at 20:00 (NSW time) or 19:00 QLD time…If this is too early for the Qld mob, we might sneak this time up to 20:30 (nsw) so this will end up 19:30 Qld start time… See, it’s so confusing all this day-light savings thing…hihi
We ended up closing this week’s net at 20:53 (NSW)

JOHN MOYLE FIELD DAY 2026 – REPORT
SARC members Pat VK2FAAD & Graeme VK2QJ met at Junction Hill before making our way to Vista Point, arriving around 11am.
Graham VK2BWC was unfortunately unable to make the trip. Pat and I soon set about putting together our stations, breaking for lunch around 12:30pm, once again missing the usual treats supplied by Graham. Pat set up the 6m, 2m & 70cm station, while I completed the 23cm, 13cm, 9cm, 6cm & 3cm bands. David VK2JUB was also unable to make it due to work commitments, leaving just Pat & myself to cover all eight (8) bands.
Both stations were operational before nightfall, with the Brisbane beacons heard on 23cm, 13cm & 3cm, as well as successful decodes on 9cm & 6cm. Several test calls with VK2 & VK4 stations were also completed Friday night. Despite the forecast, we were blessed with good weather during setup Friday afternoon with overnight temperatures dropping to 11c .
We woke to clear skies Saturday morning, the weather remained fine at Vista for most of the weekend, we could often see rain & storms all around us as seen in the photo. The weather remained fine for most of the pack down, with only one short shower just after midday Sunday. Despite the limited number of operating stations due to the new rules & scoring changes, things started well with several locals & the odd VK4 station, this continued throughout Saturday night & into Sunday morning with a few VK4 portable stations keen to make contacts. Recent modifications to my 23cm system proved successful, with the highest number of event contacts made on 23cm. Contacts were made on all bands from 6m through to 3cm with 23cm performing the best, other bands following closely behind.
The outstanding contacts were, 371km to VK4IF on 3cm (10GHz) Q65 Digital (Not a contest contact but worth noting), VK4IF were only running 500mW, yes half a watt, also 6cm & 13cm where VK4IF were only running 2w, this was repeated 7 times throughout the event. We also completed a 3cm DStar contact with VK4IF at 371km.

This shows you never know until you point & try. Stations worked were VK4IF/p, VK4WIE/p, VK2XI/p & VK2GF/p who also went out portable, VK4AFL, VK4HMD, VK4VU, VK2AMT, VK2DLR, VK2ELH, and VK2VL, plus many more. The overall number of stations were well down, nevertheless we managed 215 contacts, given the conditions & rule/scoring changes, our score wasn’t too bad , we managed our highest JMMFD scores, we’ll await the final results to see how we fared.
Pat & I are getting the hang of N1MM to log the contacts with only a few minor errors made. We packed down Sunday after the end of the event, improvements to both stations once again making it quicker & easier to pack up. Pat & I headed off the hill just after 2:30pm, we stopped for a short break at Coutts Crossing before heading home, I made it home around 17:30, with Pat arriving home around 18:30.
As always, it was a great weekend on a hilltop, flying the flag for SARC, & doing what we enjoy, we are looking forward to the Winter FD, 20th & 21st June 2026. Thanks to all who made contact with us during the event, without you it would be nothing. Good luck to all who submitted logs for the event.
Regards Graeme VK2QJ
The excellent series of images below of the recent lunar eclipse was the work of the very talented Andrew VK2ZAG. Andrew also has a strong interest in Solar Storms, CME’s etc.
The image above shows Andrew VK2XI’s great setup above Byron Bay for the Summer VHF-UHF Field Day, just completed today (Sunday 4th) complete with microwave gear. All the equipment worked very well, including the microwave setup, so well done Andrew. There will be another report from the VK2SRC club station as well.
SARC CHRISTMAS PARTY 2025
The SARC December Committee Meeting was held at 10.20am and the party followed afterwards. There was a good number in attendance. The weather was quite warm but not unpleasantly so. President Ross thanked Jeff and Julie plus Duncan and Paul who spent Saturday afternoon cleaning and tidying the clubrooms. A very pleasant day.
What’s behind the front panel of a Tait TB8100 Repeater?
Well, the photo above shows it. From left to right, an AC / DC Power supply, two PA’s (power amplifier modules), and two transceiver modules. All these are able to be accessed and controlled via software on a computer. Ross very kindly showed Jeff VK2WSR and Paul VK2AMT at the clubrooms the basics of accessing the repeater’s modules. Totally fascinating and I’m thinking that there will be more sessions involving repeater maintenance. Thanks to Ross for a fascinating session. While we were there, Jeff also plugged in and connected to one of his All-Sky Cameras running on a Raspberry Pi mini computer, via the club’s modem. de Paul VK2AMT.
PLEASE NOTE: all details and tributes to amateurs who have gone silent key are now listed as separate sub pages under the heading SILENT KEYS.

Andrew VK2XI set up at St Helena on 26-10-2025, working 23cm with the new yagi and also microwave, 2.4GHz
Today I packed the Prado and travelled down the highway to St Helena in the hills above Byron Bay to take part in the Microwave Activation Day or MAD organised by the Brisbane VHF Group. The objective was simply to test out my new, to me, 1.2, 2.4 & 3.4Ghz transverters and new 1.2Ghz 36 element Yagi. The location is well known for its clear path North to the Gold Coast and Brisbane as well as South to the Northern Rivers and importantly to Vista Point. The setup was right on the edge of the road and took longer than expected to erect as it was all uncharted waters. With the 1.2Ghz Yagi beaming South I quickly made contact with Grahame VK2QJ at Vista Point and we received 10 to 20dB over 9 signals each way, this was a very pleasing result from the new Yagi with 30W. I then swapped over to the 2.4Ghz 25W Transverter fed into 24dBi Gridpack and again made contact with Grahame with received signals around S3, another pleasing result. Unfortunately attempts to make contact on 3.4Ghz were not successful so I have some work to do there before next outing to work out why.
The expected contacts into VK4 did not eventuate either due to a poor turnout and those that did operate were working higher bands. This was disappointing but the location excites me as I will take the full station and caravan there for the Spring VHF Field Day in 4 weeks time. I hope to hear you calling CQ Field Day soon.

LATEST TOWER WORK
On Sunday morning the 12th, before the Committee Meeting, one job on the list was getting the tower ready for raising by the crane on Wednesday. Quite a few of us put some time in getting the three runs of coax cable terminated where necessary and the new cable clamps installed in the cable tray. Tony VK2RI, Duncan, Ross, Jim and Paul all put in some time helping to get the tower ready. Thanks to all.
IT’S UP! the tower is back on its slab, the next job is to fit the antennas and complete the coax cable connections.
A trip to the western division
Ross VK2ARD, Lachlan VK2FOOD, Duncan VK2DLR and Paul VK2AMT paid a visit to Julie and Jeff VK2WSR at Coonabarabran. We were all given a wonderful warm welcome by Julie and Jeff. On behalf of all of us I thank them for their hospitality. These visits are normally planned to coincide with the Open Day at the Siding Spring astronomy site. The Open Days are strongly recommended for anyone with half an interest in the night sky. Quite a number of the numerous observatories on Siding Spring Mountain are open to inspection. The site is now managed by the Australian National University in Canberra and there were quite a few ANU students on hand to explain what is happening. We also attended a lecture at the Coonabarabran Golf Club on Friday night called Science in the Pub. Four young scientists explained their fields of research to the enthralled audience. Their youthful enthusiasm for their fields of study was wonderful and they all conveyed a summary of their work in such a way that a person with average intelligence could understand their work.
On Saturday we drove up to Siding Spring and spent some hours exploring the observatories there. The instruments are normally not available to the public and it is marvellous to get up close to them and get a summary of the work done.
The image above shows just one of the great views from Siding Spring. The astronomy site is surrounded by the volcanic peaks of the Warrambungle National Park. I strongly recommend doing some of the walks into the Warrumbungles if you can. There are quite a few to chooose from. The whole region contains much to explore. Other areas of interest in the area include Mount Kaputar National Park and the radio telescope site near Narrabri named the Australia Telescope Compact Array. There are more details here:
https://www.nationalparks.nsw.gov.au/visit-a-park/parks/mount-kaputar-national-park
https://www.narrabri.atnf.csiro.au
I can only recommend a visit to the region. It is an easy day’s drive from the Lismore area. Sincere thanks to Julie and Jeff for their hospitality.

MADness at Vista Point
On Sunday 6th April, Graeme VK2QJ and Graeme VK2BWC headed to the hills 70Km west of Woolgoolga to take part in the Brisbane VHF Group’s April MAD (Microwave Activation Day) Vista Point. They regularly use this location for the John Moyle and VHF/UHF Field days, I met the two Graeme’s here just after they had setup. Graeme QJ’s Ute tray mounted station. They were preparing to make contacts with the other portable and home stations taking part in the MAD. Other stations were active from. Apologies to those I may have missed.
- Hummock Lookout Bundaberg – Kevin VK4UH and Colin VK4UV using VK4IF/p
- Kamarun Lookout Lamington National Park – Scott VK4CZ – observing were Ralf VK4GCR, Eddy VK4TJE, Scott VK4MGL, Dennis VK4DWN and AdamVK4GHZ
- Toowoomba – Martin VK4HMD
Vista Point is a wonderful take off point at 1310 meters ASL and is a perfect location for one end of the record attempt planned for today. 587.2 Km North, just out of Bundaberg at Hummock Lookout Kevin and Colin were setting up their impressive station with the aim of jointly setting new distance records.
The path from Vista Point to Hummock Lookout
I was fortunate to see firsthand Graeme’s skilfully engineered slide-on slide-off Ute mounted station consisting of a self-designed and built 4.2-meter tilt-over, extendable and rotatable tower. Both the tilt and extension are achieved with 12v actuators via a wireless pendant. The rotator is a Create RC5-1 and can achieve bearing adjustments down to 0.5 degrees. Aluminium toolboxes are mounted on either side of the tray, storage on the driver’s side and the station equipment on the passenger side. The station that covers all microwave band from 23cm to 3cm has been custom built by Graeme and consists of 2 x IC-905 and an IC-705 with automatic amplifier switching, this also incorporates temperature, current and reflected power monitoring.
Graeme’s efforts were well rewarded with a series of awesome contacts that set one personal record, one New NSW WIA record and New WIA National record as listed below.
- 23cm voice to VK4IF at Hummock Lookout Bundaberg 587.2km (personal best 23cm contact).
- 23cm digital to VK4HMD at Toowoomba 291km
- 13cm digital to VK4IF at Hummock Lookout Bundaberg 587.2km (New WIA NSW 13cm digital record)
- 9cm digital to VK4IF at Hummock Lookout Bundaberg 587.2km (New WIA National 9cm digital record)
- 6cm no contacts
- 3cm CW contact to VK4VU Brisbane 300km, one-way contact as Rod had RX only. It is hard to believe that this very impressive configuration was completed less than 18 hours prior to this event. The full list of equipment comprises.

Flu precautions : update 1 August
Please stay away if you have a cold or flu-like symptoms.
We are still asking people to sign in as they arrive, using the book on the table at the door. Use of hand sanitiser and social distancing are still sensible things to do.
