Thanks to all that assisted with the combined Clubs car rally on May 27^th. With a total 26 cars entered, everyone was kept busy keeping Rally Control informed of all the cars’ locations and their issues. Thanks to Tim VK5AV, Col VK5HCF, Lyndon VK5LRB and Nick, Greg and Gabi VK5ZGY, and Andrew VK5VKC

The weather was not too cold, and luckily the rain held off until after midnight, when it bucketed down.

James VK3JBM brought along his “Vehicle Tracking System” which greatly assisted those in Rally Control to track the location of a number of cars. This system is still being developed, but showed huge potential.

A demonstration of his system is planned at an Activity Night in the near future.

The Club’s portable 2m repeater was deployed on a hill in the Myora Forest as communications in the rally area have, in the past, proved difficult, but this time it worked a treat.

The next Rally is not scheduled until September 9^th.

Assessors received the following letter from the Australian Maritime College of the Uni of Tasmania. The AMC holds the deed for certain amateur services.The move to Class Licensing has led to a decision by AMC to remove their involvement from 2024.

As a result the ACMA will take over functions and continue to use volunteer assessors. In our club that’s currently Tim VK5AV and John VK5DJ.

The attached file is one sent to all assessors. It explains the new proposal in greater detail but be aware that this must go to public consultation before the new processes can be introduced. The letter explains this.

1/5/23 – Peter VK5BE and Nick travelled to Mount Richmond to install the newly constructed steel work on the bunker wall that will support the 4 solar panels.

Firstly, an off-set support frame was attached to the bunker wall, then a tilting solar panel mounting frame was attached. The frame tilts to the optimum positions for maximum efficiency for either summer or winter.

During the next site visit, it is hoped the 4 solar panels will be mounted and cabled into the hut.

The VK5RSE repeater is currently running on a low antenna – about one metre above the hut. In addition it is below the height of two nearby buildings in the direction of Mt Gambier and Millicent. Signals will be down. It may still be OK towards Kingston and Naracoorte.

This is an experiment to check if the clicks appearing on transmissions into the 2 metre repeater are a result of antenna fault. We also know that the SWR is very high (4:1) and the antenna analyser is coming up with some strange readings. The bottom line is that we’ll need to replace the main antenna. For the moment this temporary setup will confirm the clicks are coming from the main antenna.

I have had to reduce the power out of the repeater to prevent the desense resulting from having an antenna within 4 metres of the repeater.

The SERG Thursday morning “Coffee Club” continues to grow and grow with 11 members this week enjoying some social chat. Was great to see Dale VK5DA and Gary VK5JR join us for the first time.By chance, we all watched the tracking on our big screen of a weather balloon from the Airport on the club’s new balloon tracker that was configured by Andrew VK5MAS. Join us every Thursday at 10am at the Clubrooms.

Here are some notes from Peter. But first a big thank you to Nick and Peter for their work on Wednesday 15/2/23

Nick and I went down to Mount Richmond and completed the following :

• Removed the rust from the hut.
• Applied cold galv primer to any bare metal areas.
• Spray painted the first of 2 coats in Heritage Green.
• Obtained details and measurements of the proposed repeater installation.
• Gathered info to build a frame to support the solar panels.
• Took numerous photos.

Since arriving home, I have received a phone call from Tim VK3TIM thanking SERG for today’s work. He has become very supportive of the project and is now offering more support. I have received his permission to hold the keys to the site until the project is complete.
Tim is offering to get an arborist to the site to remove some trees that may cause some shading to the panels.
The equipment rack was measured up today, and unfortunately the blue cabinet is too tall to fit into the hut. Therefore, the mini-rack that I built, (which is at the Clubrooms) will now be pressed into service, but a new solar control panel will need to be built. I have Tim’s permission to mount it on the wall above the repeater rack.
Today I spoke with Andrew VK5VKC, who will ask his boss if we can borrow a 15m cherry picker, as the mono-pole is 12m high and we may be able to do our own antenna work. This activity has been pre-approved by Tim VK3TIM.

Things are a little overgrown at Mt Graham. Technicians take their lives in their hands when they visit, not to mention other parts while climbing over the barb wire. The sacrifices of people who work on repeaters.

We are sad to advise that Gil has passed on. His funeral service will be held graveside at the Millicent Cemetery on Monday 12th September 2022 at 11:00AM.

Gil was a regular for the Sunday broadcast and enjoyed listening and connecting with his SERG friends.

Rest in peace Gilbert.

It appears that the next launch window will be on Friday 2/9/22 at or about 12:45pm (All ET USA time about 13 hours behind us). There were various problems that caused the delay, the main one being that they could not cool the rocket engines enough – keep in mind they are fed hydrogen at extremely low temperatures (about -253 deg C) enough to rattle our teeth!

Will keep people posted on updated schedules as soon as they become available. This may mean that when the rocket finally reaches the moon it may or may not be in a favourable position for us to hear the orbiter and the lander. Fingers crossed.
