Cubical Quad Antenna 25/2/2023

A group of antenna builders travelled to Robertson on Saturday to finish off the installation of the donated cubical quad antenna.
These hams were Barrie VK2IBE, Skip VK2ALR, Stephen VK2RH, Raffy VK2RF, Bob VK2NRC and Fred VK2WS.

On a previous visit to build and erect this antenna we were forced to stop work as the mating of the boom to the spiders holding the spreaders appeared to be a mis-match. It was subsequently ascertained that the aluminium boom was out of round causing the issue.
For this visit we took the boom down and with a little ‘bush panel beating’ re circularised the boom end. With everything on the ground we were able to adjust and test fit things so we were sure that things would go back together when it was all up in the air for assembly.

We then fitted the reflector element and the radiating element to the boom, rigged the feedline and we were ready to extend the telescopic mast for testing.

This whole process sounds like a 5 minute task but all this took us about 5 hours.

The reflector of the cubical quad is a closed loop. We had initially not closed the loop as the length of the shorting wire was where the adjustment of front/back ratio was done.

Anyway, we measured the SWR, then lowered the whole antenna assembly, closed the reflector loops with some shorting wire and re-raised the antenna – and measured again.

The results were surprisingly good!

The SWR was quite flat across all three 10m, 15m and 20m ham bands. The lowest SWR (just below 1.5) was right in the low part of the SSB section (and so not that far from the CW section of the band) and even at the band edges the SWR was not higher than 1.5.

We tried rotating the antenna but quickly came across an issue where the wire termination on the reflecting element fouled the guy ropes. We lowered the antenna again and lifted the wire termination block as much as we could. Plus, we re-positioned two of the guy anchor points in closer to the mast to improve the angles. And then re-raised the telescopic mast.

We then hooked the antenna to a radio equipped with a pan-adapter and observed the signal strength of beacon signals. This was compromised a little by the fact that the beacons were DX and the ionosphere was causing some QSB. However, over an extended period of observation we feel that the antenna has a front/back ration somewhere in the region of 15-20dB. Which a very useful characteristic for our contesting operations.

As a parallel activity, we completed the replacement of the old kerb find laptop computers, with different operating systems, with three small form factor desktop machines all running the Windows 10 operating system. The desktop machines also have 10 USB ports which we need many of due to all the peripherals that are connected during contests. We also installed two 24″ monitors for each operator position and an external keyboard and mouse. This was done to improve the ergonomics and provide larger, brighter monitors with more screen real estate for the multiple windows we open up during contesting.

Raffy went through the process of cloning the HDDs the computers came equipped to SSD drives (for faster, crisper responses) and swapping the drives over.

So, in summary, we completed the tasks we set out to do and the contest site has been upgraded with a new steerable antenna and the operating environment has been upgraded too.

We are ready for some contesting.

The Service NSW and Medicare mobile apps have now both been updated to allow the COVID certificate to appear on the screen of the app after you have signed in. Please take the time to update and download the certificate onto your phone or handheld device.

WARS wins category in John moyle field day 2021

We were a little under gunned for 2021 (or so we thought) with a significantly smaller group and without our usual “high ground” on top of the hill. We set up next to the shearing shed with three antennas on 120-degree radius about a centre point adjacent to shed.

Our old genset on the opposite side of the shed so as to satisfy the portable infrastructure requirements and away we went, for our chosen 6 hour block. We operated phone, CW and digital with a small dedicated group of operators – Raffy, Skip, Tony, Jason and John.

It is worth the trip to operate in quiet conditions with significant elevation, as well as taking the win for the category. JMFD tests our capacity to operate in portable conditions as a part of community resilience in times of disaster.

VK2BV on the ISS

On 26 April, via technology managed by ARISS we participated in a contact with the ISS. It was a long signal chain that starts with a telebridge using a mobile phone link and PTT microphone that links to VK4KHZ (Shane) as a local moderator and ON4ISS (Jan) and then via RF to the ISS on 145.8 MHZ.

Our part was providing and environment and a local moderator VK2KZ Anthony Monger. There we some technical issues with a 6db variation in incoming and out going audio levels which produced a little sweating by the local operator in the room.

ARISS Contact Scheduled for Students at St Scholastica’s College, Glebe, New South Wales, Australia

April 22, 2021—Amateur Radio on the International Space Station (ARISS) has received schedule confirmation for an ARISS radio contact with astronauts. ARISS is the group that puts together special amateur radio contacts between students around the globe and crew members with ham radio licenses on the International Space Station (ISS).

This will be a telebridge contact via amateur radio and students will take turns asking their questions of Astronaut Victor Glover, amateur radio call sign KI5BKC. English is the language that will be used for this contact.  Both onsite and remote access will be provided to the student body at the time of the contact per Covid-19 guidelines. The downlink frequency for this contact is 145.800 MHZ and may be heard by listeners that are within the ISS-footprint that also encompasses the ARISS radio telebridge station.

ARISS team member Jan Poppeliers, in Aartselaar, Belgium using radio call sign ON4ISS, will serve as the ARISS relay amateur radio station.

The ARISS radio contact is scheduled for April 26, 2021 at 6:34 pm AEST (Sydney), (8:34 UTC, 4:34 am EDT, 3:34 am CDT, 2:34 am MDT and 1:34 am PDT).

St Scholastica’s College (about 1000 students) is an Independent Catholic day and boarding secondary school for girls founded by the Sisters of the Good Samaritan of the Order of St. Benedict. St Scholastica’s College is located in Glebe, a suburb of western Sidney, Australia. The school offers courses in the fields of science and mathematics in their STEM curriculum. Students also have participated in the ACTURA space program in the U.S. with some students visiting NASA facilities through a program with University New South Wales.

As time allows, students will ask these questions:

1. How has being in the space station changed your beliefs and or perspectives of the universe?
2. What have you found out on the ISS that can’t be found out on Earth?
3. Has COVID-19 had an impact on life in the space station?
4. How do you keep in touch with your family when you are in space?
5. Do you ever feel existential terror from being in space and seeing how endless the universe is? / How do you deal with this?
6. I imagine your work, being so far away and of such a vast scale, would impact your mental health. Considering this, are there ways you work on your mental health onboard, and has your experience changed the way you think?
7. What was the hardest of the requirements for space travel for you to meet?
8. Do you believe that in the future, younger people will be able to go into space? 
9. What made or motivated you to want to become an astronaut?
10. Can you see the effect of climate change from space? And if so, what are the phenomena you have observed?
11. What would you say is the most important skill for astronauts to have and master?
12. If funding for space exploration became scarce, how would you convince the world that space exploration was worth the investment?
13. Do you believe that the tests and studies you perform will cause great change and progress in the way we live or view the world?
14. When first arriving into the space station how did you feel? And how do you feel now?             
15. Is there day and night in space?
16. Is NASA training similar to Roscosmos training? If so, how? What are the similarities/differences?
17. How long did you have to train and prepare to go into space and what was the training like?
18. Have you, personally, ever had to repair a part of the ISS due to damage caused by man-made space debris? And if so, what part of the spacecraft did you repair?
19. What is the best scientific advancement or discovery that the ISS has delivered to humanity?
20. Where does your waste (rubbish and sewerage) go?
21. Is the future of space travel likely to be in the hands of private companies like Space X or government agencies like NASA?
22. What impact do you think that the ISS has had on international cooperation?

Victor Glover – Expedition 63/64


Plans are afoot for the expedition to Tooraweenah this year after being frustrated by the COVID19 pandemic in 2020.

Notwithstanding change in public heath advise we are going. For the JMFD 2021 and we will compete in the 6hr All Modes Section. The start time will be decided by the competition manger to give us a chance at another category win.

Stand by for emails and other correspondence and put 19 – 21 March in the diary.  

If you have not been on the big field trip it is great fun!

New – 2 Letter Callsign – VK2YV

The club has been successful in gaining an additional 2 letter callsign. – VK2YV

It may be familiar to you.  It was Rob Bellamy’s (SK) call sign for a number of years. We were able to secure the callsign after a recommendation from the AMC when the call became available.

This additional call sign will enable us to operate from 2 locations as “the club” which will be useful for expeditions and away trips as well as competition. For example, it would be great to use for it the now annual trip to Tooraweenah as a commemoration of Rob. As well as maybe an additional anchor station for the ferry contest. Maybe at Circular Quay or even Manly.

We could also consider it for use during competition where the club might operate from say Robertson as well as another place.

To an extent we can make this up as we go along. Personally, I am incredibly pleased that we have been able to secure another 2 letter callsign, but more so because it was the callsign of our benefactor. 

Rob was one of a kind, a rare soul in these days of immediate gratitude and self-interest, he was a gentleman, a member of the bar, (ask any barrister, who will tell you it is an honourable pursuit, excepting for the following; the person on the bench, my learned colleague, and the defendant, unless of course you are appearing for the poor hard done by defendant)

We never saw Bellamy at the Bar it would add another dimension. Members of the bench say he was pretty-good; Had we need of a barrister we would hope for one with the integrity and skill of Robert Bellamy.

He was a commissioned officer in the RAAF, we can forgive him being a member of the junior service but apparently the Airforce uniform is prettier, and you get more girls! Also, the toys are better in the Airforce.

There is a pattern, he liked things involving costumes!

Rob lived life on the edge, the criteria, went something like this…

  • Will it be fun?
  • Will I learn something?
  • How close to the edge?
  • Do I get to play with clever stuff?
  • Does it have me understand the physical world more?
