NEW Meeting Venue from June 2017

Due to some over active white ants, WARG has has to find a new meeting venue. Keeping the link between WARG and the Scouts, we will be metting at the Pelican Point Sea Scouts hall, Australia II Drive, Crawley. This move is until the redevelopment of the Peter Hughes Scout Communication Cenre has been completed. Our firs meeting at the new venue will be the 12th June 2017.

AGM and Equipment Auction!

A reminder that WARG’s next meeting on Monday May 2nd is our AGM – and will feature an equipment auction at the close of proceedings.

As usual, the main business of the AGM is to elect a new Committee for the coming year. Whilst many of WARG’s office holders intend to re-nominate – including myself as Secretary – this is an opportunity for others who are financial members of WARG and want to contribute more to the running of the group.

WARG’s committee aims to always operate in a collaborative fashion, and not to take over discussions or make decisions which should be the property of the wider group. The AGM is an important night and we look forward to seeing you there, at WARG’s usual meeting venue, the Peter Hughes Scout Communications Centre, corner of Gibbs St and Welshpool Rd, East Cannington.

All are welcome to attend. Doors will be open at 7, for a 7:30 start. Treasurer John will be on hand to take payments from any members who haven’t yet renewed. A short General meeting will also take place, alongside the AGM. Tea & coffee are available, and there’s usually time for socialising before and after the meeting.

WARG Treasurer John VK6JAH advises that the auction is on behalf of the estate of Syd VK6SMH (SK) who sadly passed away last year, his family have asked WARG to assist in disposing of remaining equipment. All the gear is said to be in working order, but the WARG Committee has had no opportunity to fully test any item. As such no warranty can be given regarding the working condition or otherwise of any item offered.

All procedes from the sale of the equipment will go to WARG funds.

Below is a list of the donated equipment and attached are photographs of the same.

Site visit to Kellerberrin VK6RKN

Monday April 18th happened to be World Amateur Radio Day – and a group of WARG members decided to celebrate the day by travelling to Kellerberrin, about 200km east of Perth, for a day’s work on the VK6RKN repeater site. Trevor VK6MS and myself travelled up from Perth, Peter VK6PK joined us along the way from Wooroloo, and we met Bruce VK6LAW and Pete VK6FUN on site at the repeater.

This site had previously suffered a lightning strike, which did significant damage and put the 2m repeater off air. Whilst partial work had been done to restore the service, it hadn’t been previously possible to climb the mast and replace damaged antennas and feedlines. This was the main aim of the working party, and thanks to our combined effort – and particularly the work of Trevor VK6MS – we had great success on the day.

WARG recently was fortunate to obtain a donation of high quality low-loss antenna cable (LDF4-50 equivalent) from David, ex-VK6NFH. Prior to the working bee this was prepared and checked ready for transport to site and installation. Ray VK6ZRW had previously retuned the cavities, and a replacement antenna and the repaired repeater/cavities had already been transported to site and installed on test, thanks to the previous efforts of VK6PK, VK6FUN and Colin VK6ACT. A new UHF CB antenna was already on site courtesy of the shire, who had asked if we could investigate the CB repeater performance in consideration of WARG’s site access for the 2m repeater.

On the day, Trevor VK6MS scaled the 45m mast, and with the rest of us as ground crew, we removed and lowered the faulty 2m and UHF CB antennas, hoisted the new feedline aloft, and fitted replacement antennas, including a stacked phased-array dipole for the UHF CB, and a dual-band X-300 Diamond for WARG usage. The CB phased-array is all stainless-steel welded construction, and sits atop the mast, offering a greater degree of lightning protection in future. The WARG dual-band sits on an outrigger about a metre or so below the mast top, hopefully out of the firing line, whilst still achieving good height for coverage. The new feedline is secured with stainless cable ties and earthed top and bottom to the mast. At ground level the feedline entry point to the hut was improved with a new gland plate being fabricated and installed, along with a lightning arrestor at the entry point, and new internal cabling to the repeater and APRS equipment.

Due to the fading daylight, there was not time for a full spec-check and investigation of the repeater and APRS functions, but on a quick test, all was working to a reasonable standard. Mobile tests on the homeward journey showed the repeater coverage now extending westwards to Cunderdin and north to Baandee, with base stations in Merredin also being able to work VK6RKN. (On the down side, the coverage in the Perth Hills seems to have dropped off…but I would say that is outweighed by the local improvements…)

A big thank you to VK6MS for the climbing, and to Bruce VK6LAW, who used his local contacts to solve a number of problems on the day. Thanks are also due to VK6FUN, VK6PK and all others who donated time, effort or materials to make the day a success.

There is still work to be done – the APRS antenna (Diamond 2m colinear at about 15m level) is showing high SWR, which needs investigation, although the APRS is still working OK by all reports. The repeater’s RX mute setting is a bit high, and it still seems to be de-sensing on weaker signals at the fringes – plus the internal hut cabling could do with a bit of tidying up. All tasks for a future working bee…to be scheduled.

Reports on the coverage and performance of the repeater,  and APRS service would be appreciated, either on-air during WARG’s Sunday net;  via email, to secretary AT whisky alpha romeo golf DOT org DOT au – or come along to a WARG meeting and tell us about it!

Working Bee – VK6RTH (Tic Hill) 15-05-2015

Working Bee – VK6RTH – 15-05-2015.

A short notice to members just reminding all that a working bee has been scheduled for Tic Hill, by Site Manager Bob VK6POP. The Bee is scheduled for Friday May 15th 2015, Meeting is at 0930, Liason Frequency for the morning will be the star of the day, Tic Hill (146.800). If you are planning on attending to assist, please notify Bob via the reflector.

A number of tasks require attention including installation of solar panels (if anyone is able to climb a mast, please contact Bob), installation of a regulator, servicing of the batterys and a general site cleanup and tidy.

For those who haven’t attended a site working bee for a while, or who haven’t been to the Tic Hill site, the information below refers:

WARG will appoint team leaders or co-ordinators for the working bee to ensure everyone goes home safely – these person/s will be identified to you on the day, please follow their instructions.

The repeater site is on private land, and prior permission is required for access. No entry for pets or other animals. Leave all gates as found, and take care not to disturb livestock, damage any crop or contaminate water supplies (eg: no hand washing in stock troughs or similar). Even though it is a lower risk time of year, fire precautions should also be taken. All rubbish and waste items must be removed from the site at the conclusion of the works.

The repeater site itself is not readily accessible by 2WD vehicle. Therefore arrangements will need to be made with the working team beforehand so everyone has suitable transport from the base of the hill to the site if required.

The site is unattended, with no toilets or other facilities of any kind. It is your responsibility to bring with you everything you will need for the day, including food, and water for drinking & washing, etc. There is little indoor space to shelter from the elements, so hats, sunglasses & sunscreen, or rain wear etc should be carried, depending on the weather forecasts. Other personal protective equipment (PPE) such as boots, hardhat, gloves, safety glasses, earplugs etc may be required, depending on the work we are doing – if you have your own PPE, please bring it along. Likewise bring a first aid kit if you have one, although some first aid supplies will be available on site.

The site is shared with other users, and their equipment & presence must be respected. Keep the usual distance from antennas and equipment you are not familiar with. Some structures on the site may contain asbestos, the usual precautions should apply here. Radio masts shall only be climbed by appropriately qualified or experienced people with the correct safety equipment.

The site is in a scrub/bushland setting, and – especially in summer – care must be taken not to do anything which may start a fire. Extra care must be taken with the use of gas soldering irons, power tools, or clearing work likely to cause sparks. Smokers should be especially careful – or preferably, quit! (At least for the day…)

In addition there may be the usual hazards associated with bushland, including spiders & snakes – wear long pants and closed shoes, preferably safety boots. Take care when moving near bush areas.

Besides your tool box, multimeter, SWR meter and handheld radios, useful items to bring to a repeater site working bee could include: insect spray; stepladder & garden tools for trimming tree limbs and clearing scrub from guy wires; rags, brushes and cleaners for removing dust from equipment; camera & notepad for documenting things; heavy cable ties, black electrical tape, silastic sealant; coax joiners & adaptors…. this list is not exhaustive. In the end, what you bring to a working bee is limited only by your transport, imagination and what’s in your shack – but remember it is your responsibility for keeping track of items you bring to site, and making sure you get them back at the end of the day.

Pets & small children should not be part of a working bee. If you are caring for children and have no choice but to bring them, it is your responsibility to supervise them, keep them out of harm’s way, and prevent them becoming a risk to others.

Fusion Presentation – 1/12/2014

For our upcoming meeting on Monday December 1, Will VK6UU has kindly agreed to bring along his Fusion equipment and give a presentation about the Fusion system.

This will be a good opportunity to have a close look at this new digital voice protocol, and compare/contrast to other systems. We encourage as many members as possible to turn up.

Usual venue, Peter Hughes Scout Communications Centre, cnr Gibbs St and Welshpool Rd East Cannington. Doors should be open at 7 for a 7:30pm start. We envisage a brief business-meeting session, and then hand over to Will for the presentation. Any other general meeting items can be dealt with after the presentation, if needs be.

This will be our last meeting before Christmas, and a good chance for a catch up generally. There is no meeting scheduled in January due to the proximity to Christmas/New Year break and hot conditions, so we won’t be all meeting together again until early February. (Although there should be some working bees and other activities in December/January).

Some videos in relation to the system can be found below. Thanks go to Will VK6UU for his time spent on the new system.

We look forward to seeing you there, to enjoy the presentation, a coffee and possibly even some Christmas Treats.

Working Bee – VK6RCT 28/9/14

After some time off the air, sitting in silence, it is now time to continue the work at VK6RCT to re-instate the repeater, give the site a spring clean and overhaul in time for the summer months.

The proposed date for this is Sunday 28th September 2014, with the plan being for an early departure from Perth with an arrival time allowing us to (all going according to plan) complete the required work and site clean within the day. As with all our repeater sites, we rely on the time and effort of our members and the wider amateur community as a whole and given the remoteness of this site all available hands that could be mustered for the day would be greatly appreciated.

A suitable meeting point and agenda for the day will be arranged and distributed when tasks are confirmed and we have an idea on numbers. Site manager Craig VK6FLAM is coordinating the effort on the day and will be conducting a briefing before work starts. Anyone interested in volunteering can contact VK6FLAM directly on (vk6flam at g mail dot com) via email, or advise on the Sunday morning nets in the weeks beforehand. (The net is on VK6RLM at 1030 local).

For those who haven’t attended a site working bee for a while, or who haven’t been to Cataby site, the information below refers:

WARG will appoint team leaders or co-ordinators for the working bee to ensure everyone goes home safely – these person/s will be identified to you on the day, please follow their instructions.

The Cataby repeater site is on private farmland, and prior permission is required for access. No entry for pets or other animals. Leave all gates as found, and take care not to disturb livestock, damage any crop or contaminate water supplies (eg: no hand washing in stock troughs or similar). Even though it is a lower risk time of year, fire precautions should also be taken. All rubbish and waste items must be removed from the site at the conclusion of the works.

Cataby is located some two hours north of Perth. Those attending the site need to have adequate fuel for the journey to & from, and ensure their vehicles are in good order and suitable for country driving, including gravel roads. The repeater site itself is not readily accessible by 2WD vehicle. Therefore arrangements will need to be made with the working team beforehand so everyone has suitable transport from the base of the hill to the site if required.

The site is unattended, with no mains power connected, and no toilets or other facilities of any kind. It is your responsibility to bring with you everything you will need for the day, including food, and water for drinking & washing, etc. There is little indoor space to shelter from the elements, so hats, sunglasses & sunscreen, or rain wear etc should be carried, depending on the weather forecasts. Other personal protective equipment (PPE) such as boots, hardhat, gloves, safety glasses, earplugs etc may be required, depending on the work we are doing – if you have your own PPE, please bring it along. Likewise bring a first aid kit if you have one, although some first aid supplies will be available on site.

The Cataby site is shared with other users, and their equipment & presence must be respected. There are no services on site which pose an EMC or radiation hazard at ground level, but keep the usual distance from antennas and equipment you are not familiar with. Some structures on the site may contain asbestos, the usual precautions should apply here. Radio masts shall only be climbed by appropriately qualified or experienced people with the correct safety equipment.

The site is in a scrub/bushland setting, and – especially in summer – care must be taken not to do anything which may start a fire. Extra care must be taken with the use of gas soldering irons, power tools, or clearing work likely to cause sparks. Smokers should be especially careful – or preferably, quit!

Equipment Check day – Sunday June 23rd – all welcome

WARG will be hosting a “Check your equipment” day at our usual venue, Peter Hughes Scout Communications Centre, on Sunday 23 June 2013, starting at 11am.

The purpose of the “Check your equipment” day is an opportunity for Amateurs to bring along their own equipment to be tested using professional-quality calibrated instruments.
Testing will focus on the usual RF parameters, so if you are wondering about your rig’s deviation or modulation limits, S Meter accuracy, receiver sensitivity or the like, now you can find out for sure. Likewise your other station equipment – whether your SWR-Power meter reads correctly, or your dummy load is a good 50 ohm match on all the bands; and so on.

WARG will supply professional quality test equipment and knowledgeable people to drive it. We will also provide the usual 13.8V DC and mains AC power supplies

You will need to bring your equipment, and all accessories required for it to operate on test,like the power cables, microphone, and any other specialist items. If you’re bringing one or more handhelds, ensure the batteries are well charged.

We’ll be set up to fully check equipment operating from 160m through to 70cm, mainly in analogue-based modes, such as SSB or CW, and FM, and RF power levels from QRP to the legal limit.

We will be able to check function and basic accuracy of RF power and SWR meters, and impedance match and frequency response of dummy loads or RF filters. We can also do resonance sweeps of some VHF/ UHF antennas, .

We may be able to test other things … if you aren’t sure, bring it along! As long as it can be safely powered up on the bench, we can advise on the day. Or if you can offer to test certain equipment, please let us know.

For each item tested we will give you a written summary sheet, outlining performance.

Note that we won’t be geared up to to repair or realign equipment – but we will be happy to give advice if we find anything amiss. (If anyone wants to consider working on their own gear, there may be a corner available – but BYO tools and everything…!)

Cost of all this is only a gold coin donation per tested item (depending on how many bands you want tested – thorough tests of multiband/mode rigs will take longer, and will thus warrant additional donation). WARG members – or those who join WARG on the day – can have some items tested free. (WARG membership is still only $25.00).

With events like the RD contest and Hamfest not far away, June 23rd is a good opportunity to put your gear through its paces

The equipment check day will start around 11 am, and we need to be packed up by around 4 pm. A sausage-sizzle lunch, soft drinks, tea and coffee and afternoon snacks will be available, all at reasonable prices, Funds raised will go into keeping our repeaters on the air

We would appreciate RSVP, for catering purposes, and also to get an idea of how much equipment we have to test. Also we are looking for volunteers to help on the day – whether you have professional-grade radio comms test setup you can bring – or are willing to help on the day, cooking the sausage sizzle etc, all assistance would be appreciated.

Email us through the Contact Page, or call in to our on-air net, Sundays at 10:30 local on VK6RLM, 146.750.

So, we hope to see you at WARG’s “Check Your Equipment” day, June 23rd, Sunday, 11am to 4pm, Peter Hughes Scout Communications Centre, corner Gibbs St and Welshpool Rd East Cannington.

BR & 73,
Anthony VK6AXB
