A warning from Telstra is that the 2G mobile network is to be shut down at the end of November this year.  The telecom company has written to its affected users advising them they need to switch to newer 3G or 4G technology.

Meanwhile, WIA members registered with MEMNET who use PC’s and web browsers which are more than 10 years old such as Internet Explorer 6 or Opera version 5, will need to upgrade as support is being withdrawn for these early browsers.

Sunday the 28th August Omni Software the provider of the WIA’s MEMNET service will be undertaking maintenance works and system improvements to support the latest security protocols, Omni have advised that any users affected by the upgrade will need to upgrade from their old Web browser versions.  They advise that all versions of Chrome, Safari, Firefox, and Internet Explorer 7 and above should be unaffected, although they recommend all users update their browsers to the latest version available.

The WIA apologises for the short notice given but timing of the change is purely in the hands of the MEMNET software provider.

Amateur Radio Sleuthing Pins Down Source of Strange RF Interference

Evanston RFI-2From the ARRL, original post here08/09/2016

Police in Evanston, Illinois, contacted the ARRL Lab, after an apparent interference source began plaguing wireless vehicle key fobs, cell phones, and other wireless electronics.  Key fob owners found they could not open or start their vehicles remotely until their vehicles were towed at least a block away, nor were they able to call for help on their cell phones when problems occurred.  The police turned to ARRL for help after striking out with the FCC, which told them it considered key fob malfunctions a problem for automakers, although the interference was affecting not just key fobs but cell phones, which are a licensed radio service.  ARRL Lab EMC Specialist Mike Gruber, W1MG, believes the FCC should have paid more attention.

“This situation is indicative of what can happen as a result of insufficient FCC enforcement, especially with regard to electrical noise and noncompliant consumer devices,” Gruber said.

Evanston authorities worried that a serious situation could develop if someone were unable to call 911, putting public safety at risk.  They also were concerned that the RFI could be intentional and indicate some nefarious or illegal activity.  Given the seriousness of this situation, Gruber contacted Central Division Director Kermit Carlson, W9XA, to ask if he could look into the matter.

On June 2, Carlson met with an Evanston police officer, her sergeant, a local business owner, and the local alderman, and he quickly confirmed that the 600 block of Dempster Avenue in Evanston was plagued with an odd RFI problem.  Carlson determined that the problem prevailed along a set of eight on-street parallel parking spots in the downtown commercial district of the North Chicago suburb.

Carlson employed a Radar Engineers 240A Noise Signature Receiver and UHF Yagi antenna to survey the affected block.  Since key fobs typically operate at around 315 MHz and 433 MHz, he looked on both frequencies.  The survey identified several noise sources in the affected block, but in particular a strong signal in the middle of the block.  The interference source turned out to be a recently replaced neon sign switching-mode power supply, which was generating a substantial signal within the on-street parking area just across the sidewalk, between 8 and 40 feet from the sign.

The problematic power supply interference also disabled Carlson’s cell phone when he was within a few feet of the device.  Carlson anticipated that further investigation would show that the harmful interference could disrupt licensed radio services in close proximity.  The troublesome transformer was not replaced, but the building owner agreed to turn off the sign should problems arise.

Carlson called the Evanston case “a particularly alarming example of radio interference,” especially since local authorities considered it a public safety matter.  “This situation demonstrates the electromagnetic compatibility problems that are evolving in an atmosphere of noncompliant, unintentional RF-emitting devices,” he said.

A return visit to the area with calibrated antennas and equipment capable of measuring the radiated signal strength with quasi-peak detection is planned for later this year.  Since the initial visit, several other instances of unexplained key fob malfunctions have been reported in the Greater Chicago area. — Thanks to Kermit Carlson, W9XA, and Mike Gruber, W1MG

ORARC Remembrance Day Contest report

A big thank you to Steve VK2ZSW/VK2WYN for the following excellent recap of what was a very enjoyable event.  Steve writes:

Remembrance Day Contest 2016 at the farm of Larry Lindsay VK2CLL

The day started well for those of us that were there, CLL, VIV and ZSW, we waited for Henry ZHE to arrive so he could tow the van into situ.  But having left home around 0900 Henry arrived closer to 1200 than 1155 so we were a little late getting started.  Henry detoured for breakfast at Maccas, I think he was buying a new car while at it, how many hours does it take to travel to Wauchope, unless you come via Taree?

Richard CHC arrived and began to setup for lunch, then Lyle SMI arrived and we began to setup the trailer mast and the caravan while Richard started the obligatory sausages and onions for lunch.  Very hard to concentrate on antennae while the smell of snags and onions were wafting through the air.  To cap it off Larry, being the generous host that he was, brought out some ‘soft’ drinks for us over worked, hot antenna setter uppers.  We had to have a break and a rest, how can anyone keep going minute after minute in the hot sun when there are coldies waiting?  Now where was I, something about a contest, oh yes, we had a break then back to work.  Something like an hour later we finished erecting the trailer mast and aerials.  I mean that was surely coffee time, so Larry, again to the rescue, made brewed coffee and supplied a variety of home-made cakes and biscuits, we needed the sustenance if we were to get on air and slave over a hot radio.

Someone mentioned something about a contest so Henry went to work, warming the seat in the caravan, while racking up the contacts.  Henry likes to do his own logging so the rest of us were busy eating cakes and drinking coldies and coffee, no not at the same time, fair dinkum, well maybe the coffee and cakes were consumed at the same time.

The caravan generator sprung into life, quietest it ever was too and funny but it did not use a drop of fuel, maybe because we tapped into Larry’s mains supply for the van.  I think the biggest power drain would have been the radiator Lyle had on while trying to catch some zees, alright zeds, during the night, while he was supposed to be operating 160m.  It was a cold night, I know, because Richard and Lyle told me.  Richard spent some of the night in his tent, I am shivering thinking about it.

Larry had turned on a magnificent day of sunshine with a gentle breeze, and did I mention the brewed coffee, ‘coldies’ and cakes.

Sunday turned out another brilliant day, I arrived around 0830 while everyone was getting ready for another day of coldies, coffee and cakes, oh and contesting.  Richard had the sausages, bacon and eggs on the barbie while someone toasted the buns.  Later in the morning Larry brought out the brewed coffee and cakes again, it was hard work but someone had to do it.

I was a little peeved while contesting, I knew we were there for something, a good 25% of my contacts called me Henry, obviously re contacts from the day before, enough to give a guy a complex, anyway I got my own back by telling them Henry was outside having a coffee, this must have been for an hour, so everyone now thinks Henry takes hour long coffee breaks.  Beside me was Rob CRF ably handling the logging software.  Being a male, I am always being told (by the wife) I can only do one thing at a time so Rob did the logging.  I will not comment any further on the one thing at a time issue.  It was so hot in that corner of the van I wondered if Lyle left the radiator on or the van was on fire.  I hope it was the latter, otherwise Larry is going to have a massive power bill.

After it was all over, we had to have a coldie and some lunch before pulling everything down, and apart, so Richard did it again, sausages, bacon, eggs and onions went down well.  Then it was time for deconstruct which took a tenth of the time that it took to construct.  However it did take another hour for us to pack the van the way it should be done, said Henry.

Overall a great weekend, great fellowship and great food, oh and some contest contacts too.  The views at Larry’s are as good as it gets and so is the hospitality, thanks Larry.

Looking forward to the next contest at Larry’s.

If I’ve learnt anything for Steve’s very humorous read, it’s that I should get there earlier!  I arrived as Larry was heading to bed and missed out on all of the foodstuffs and beverages!  I did eat my fair share of biscuits while operating through to 1am though!  The club also had a guest operator, Craig VK2F??? who thoroughly enjoyed the experience and good conversation.

Wireless ANZAC goes on exhibition

Australian World War I Wireless Operator Eric Keast Burke, a photographer, journalist and radio experimenter with the amateur callsign XMO, has a public exhibition that starts this week at a gallery in Melbourne’s east.  The Australian War Memorial reports very little has been written about the Wireless ANZACs in Mesopotamia, due to them being small in number and mainly technical troops keeping the battlefield lines of communications open.

The ANZAC 100 series of articles in Amateur Radio magazine 2015 also covered the work of Wireless ANZACs, including Bert Billings XJP and Arnold Holst XPH.

Now comes the story of Eric Keast Burke XMO who was in Mesopotamia from 1918-19 in the 1st Australian Wireless Signal Squadron, Mesopotamian Expeditionary Force.  Born in Christchurch, New Zealand, he went to Sydney with his family in 1904.  He joined the Australian Infantry Force after training at Moore Park Sydney.  He also helped his father edit the Australasian Photo-Review.  Late in 1917, Eric was sent to Mesopotamia as part of the Australian and New Zealand Wireless Signal Squadron, and took a camera with accessories to help record the experience.

His squadron stayed in the region for a year after the armistice.  Proudly through photos and lantern slides he held lectures that eventual funded publication of the wireless unit history.

These are at The Highway Gallery in Mt Waverley with its exhibition of ‘Horse & Morse WWI’, from August 19 to September 11.  During World War II Eric also served as a Captain in the Volunteer Defence Corps, and worked in intelligence.
