Website Upgrade

Hi all,

Just letting you know that we are in the process of upgrading the website. During this process some links may break, but we hope to have the upgrade completed in the near future.

Thanks for your patience. 73.

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.

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,

New DSTAR Repeater in Perth

As there have been ongoing problems with the VK6RWN DSTAR Gateway server, it’s been removed from site and connected at Heath VK6TWO’s QTH for remote maintenance by the DSTAR Guru’s.

To assist in getting Perth DSTAR users back ‘online’, Heath VK6TWO is in the process of building a standalone DSTAR Repeater Node which will enable registered DSTAR users to ‘connect’ to the worldwide DSTAR network.

Testing is currently in progress and it’s expected that the node will go live late July.

Pogo-Stick Antenna Working Bee – Saturday 14th July

Saturday morning 14th July will saw a club working bee to manufacture our famous ‘Pogo-Stick’ antennas for sale at the Anual Perth Hamfest.

Mass production of all of the ‘parts’ took off quite quickly, however the assembly hit a ‘road block’ when it came to optimising/refining the design. Several hours were spent ‘tweaking’ and testing with very expensive test equipment till we came up with a final build which enabled the antenna to be usable across the entire 2m band.

Along with several saussages in bread, the assembly line was back in full swing.

~20 antennas were completed and individually tested.

Thanks to 6HRB, Dot, 6ZRW, ZRW-Jr, 6AXB, 6JAH, 6FMON, 6TWO, 6LV, 6FLEX, 6BDO, 6FJON, 6KMC, 6ZMS,TOM.

 

New Perth Repeater Site – VK6RLM

Negotiations are in place for a new WARG repeater site. Coverage is expected to be the majority of the Perth are.

It’s expected that the site will be used for hosting VK6RLM after a long period without a home. Once installed, Echo/IRLP is expected to be connected up to the repeater to enable a broader coverage Echolink/IRLP round Perth.

Bringing RLM back on air will enable all of the regular ‘nets’ to relocate back to 146.750, allowing VK6RAP to be free for general/mobile voice traffic.

Video Webconferencing Trials

In 2011 Heath VK6TWO started researching the use of ‘WebConferencing’ for use at committee and planning meetings. This was brought on by several key active members often working away from the Perth area which made attending/arranging meetings rather difficult.

Given recent discussion and interest in the idea, further research has been done and the committee have trialed several solutions for suitability for GM’s, Practical sessions, Committee meetings and planning meetings.

It’s expected that we may end up with two soltions aimed at differnt uses. First being a featureful and interactive solution to enable effective planning and committee meetings, and the second being for general meetings so that members can ‘attend’ via webconference.  This should enable more time to be spent on ‘making progress’ instead of driving in the car to/from meetings.

Further testing will continue by the committee, potentially for some initial ‘planning’ and once the best solution is decided on, the GM preferred solution will be sent out to enable members to remotely attend meetings.

WARG Practical and Information sessions – Meetings

WARG is changing the way meetings are run to include more informational/practical sessions. We’re considering bi-monthly General Meetings, where the alternate month will involve informational/practical sessions. We’re also looking at the restructure of formal General Meetings to ‘compress’ the formalities to enable simular informative sessions to follow.

Please let us know any topics you’d like to learn about related to Repeaters/AR.

Some Ideas we have so far…

Meeting:

Radio measurements – Bring along your mobile/HT radios and we’ll test things like audio levels, deviation, power output, frequency shift etc.
Learn how/why different stations sound different via the repeaters

Meeting:

Roleystone site visit – Come along and see what a repeater site looks like.
Learn about all of the devices required for a repeater, how they connect, and what they look like.

Meeting:

WARG network and features – Learn what repeaters are out there and what features they have availabale to users.
APRS network – Learn what APRS digipeaters/gateways are out there and what features they have availabale to users.

Meeting:

sweep/tune a complete set of new cavities for Tic Hill
sweep/tune/test other cavities in container
test/refurbish spare antennas in container

Meeting:

Repeater theory – Learn how a repeater works, what parts there are, what functions are available
building up spare repeaters

Meeting:

Program up APRS digipeaters x3
Manufacture/mount APRS enclosures x3
presentation on APRS graphs/monitoring

Meeting:

Brainstorming/presenting smart controller features for smart linking

System Expansion planning
System refurbishment planning

Meeting:

Build new DC distribution boards x3
testing of old Walliston Batteries

Victoria Park 70cm Repeater

The Vic Park 70cm repeater VK6RVP was returned to the Vic Park area in 2011. The repeater is currently only running on a Discone antenna so the repeater range is quite limited. When time/equipment permits, The repeater will have a dual band co-linear(previously used for this repeater) installed which should help improve it’s coverage. The new location is less ideal than its location over the past few years, and with a lower mast, though it’s expected that it will still be sufficeient to give coverage to the CBD as was it’s original purpose.

Thanks to William VK6KWT, VK6TWO and VK6FMON for the installation.

Roleystone Working Bee – 18th Feb 2012

Another productive ~5hr working bee at Roleystone on Feb 18th. Tasks carried out were:

New Cavities swept, tuned and tested on 146.700
Old Cavities swept and tuned (then returned to service – new ones will now go to Tic Hill)
Foliage under Guy Wires removed
Foliage around Shacks removed
Foliage around HF Beacon Antenna removed
Foliage along driveway removed
Mute levels adjusted
re terminated 23cm coax connector
took measurements in preparation for cable tray between mast and shack.
Took several photos
Consumed Coffee
Consumed Muffins
Consumed Smartie Choc Chip Cookies
Suffered many prickles/thorns/splinters from bushes.

Thanks to those who gave signal reports at the time. We’d appreciate if everyone could give an indication of access coverage since the changes.

Sweep plots were captured and will either get published on the WARG website or emailed out on this list. (please contact me if you would like me to send you a copy directly)

We will require another working bee at some stage in the near future to:

Install cable tray
recover coax/ethernet cables from Mast
Possibly swap main antenna (pending changes to coverage reports)
Commission 3rd run of LDF5-50 (already installed)
remove foliage around perimeter/fire break
Level checks on audio interfaces (repeaters and news link)
Sweep DSTAR 2m Cavities
General tidy up of cable routing within shack
Possibly recommission VK6BBR
Document cables/connectors/interfaces for all equipment (for site database)

Many Thanks to VK6TWO, VK6FMON, Bruno, VK6AIF, VK6ZRW, VK6DB, VK6AXB, VK6LV, VK6JAH, VK6ZMS
