WIA submission for allocation at 70 MHz

Submissions

The WIA has lodged a submission with the Australian Communications and Media Authority (ACMA) concerning interest in an amateur allocation in the 70 MHz band.  On 22 June 2016, the Australian Communications and Media Authority (ACMA) opened consultation on proposed updates to frequency plans for the 70.0-87.5 MHz and 148-174 MHz VHF bands, with a closing date of 1 August 2016.

You get little time to respond to government consultations these days.  The ACMA is proposing to update its Radiocommunications Assignment and Licensing Instruction document, which covers these VHF bands, known as RALI MS 42.

As the WIA had signified interest in a 70 MHz amateur allocation to the ACMA back in July 2014, the Spectrum Strategy Committee decided that a submission to this consultation was in order, principally to flag the amateur radio community’s interest.  Historically, the 70.0-87.5 MHz band has been used by commercial, community, government and defence communications services.  However, the WIA has been aware for some time that interest in, and use of, 70.0-70.5 MHz has declined across Australia.  There is also a Low Interference Potential (LIPD) band at 70–70.24375 MHz, with a maximum permitted power of 100 mW.

The WIA is pitching for use of an amateur allocation between 70 and 70.5 MHz that aligns with allocations across Region 1, which covers Europe, Russia, the Mediterranean, Middle East and Africa.  These Region 1 allocations are widely known as the four metre band.  The band 69.9 MHz – 70.5 MHz is listed in the “European Table of Frequency Allocations and Applications” as a secondary amateur allocation.

It remains to be seen whether the ACMA’s consultation round on RALI MS 42 will flush out renewed interest from other stakeholders.  Whatever changes the ACMA decides to make to the RALI, there’s another step to go, with consultation on updating the Australian Radio Frequency Spectrum Plan (ARSP) to commence shortly.  The ACMA reviews and revises the ARSP after each World Radiocommunications Conference.  The last one was WRC-15, which concluded at the end of November last year.

The first website went public 25 years ago

The internet just marked another major milestone.  The first website,  Tim Berners-Lee’s description of the World Wide Web project, went public 25 years ago on August 6th, 1991.  The launch was unceremonious — Berners-Lee announced the project on a Usenet group, and it wasn’t until after August 23rd that new users visited the site.  However, the launch effectively marked the start of the web as a widely available tool.

There wasn’t exactly a rush to embrace the technology, mind you.  The big leaps toward the mainstream came in 1993, when NCSA released the first widely popular web browser (Mosaic) and CERN helped adoption by making the web’s software both free and open source.  Berners-Lee’s original approach to the web treated it more as a platform for academic collaboration than a revolution.  Still, there’s no denying that the events of 1991 got the ball rolling on a fundamental shift in communication.

DIY Satellite Rotators

Paul's $25 Rotator

Stuart VK2FSTU has found an interesting article on a cheap home-brew satellite tracker.  Stuart writes:

Grabbed this article from Flipboard as it may interest a few people. When I retire and have time to fiddle I’ll be able to do these sort of things myself, as it interests me I thought it may interest a few others as well.

Read the article here along with loads of construction images.

The satellite tracker is being used in this instance to track US Weather Satellites and there are some issues with this design for Ham use – most glaringly that the servos stop working from RF interference when you’re transmitting.  I’d also be unsure of servo’s ability to survive for any length of time with a typical amateur satellite Yagi mounted on top – I’d think the windage and weight would kill those servos quite quickly.

Nevertheless, this is an excellent example of what can be achieved these days with a little ingenuity, some cheap eBay parts and an Arduino.  The designer puts the parts cost at $25 USD!

Those of you who get the WIA’s Amateur Radio magazine may have seen a similar, more costly but significantly more rugged satellite rotator feature on the cover of the May 2016 issue:

AR RotatorThis design is from Julie VK3FOWL and Joe VK3YSP of the School Amateur Radio Club Network and uses beefier stepper motors in place of servos and a Gyro & Compass sensor to orient itself.  You can read the AR article here and construction info is here.  I have all of the parts ready to go shy of the Arrow Satellite Antenna – now to find the time to build it!

SARC Rotator Case

Parts for this design, excluding some sundry items (and the antenna) cost around $105 AUD.  Pretty amazing for such a rugged design with fully automated tracking!  A big thank you to Julie and Joe of SARC for sharing their fantastic design!

Garage Sale shack equipment VK2ZCV

Keith Anderson, VK2FKJA says:

Would it be possible to place a notice on the club website advising of a Garage Sale being held this coming Saturday at the home address of Bill Sinclair VK2ZCV.

Also there is photographs of some equipment that is for sale by auction on the Facebook page.

Any help in promoting this would I am sure be appreciated by Bill’s family as Bill is still in rehabilitation at Wauchope Hospital; he is recovering slowly.

Many Thanks, Keith Anderson VK2FKJA

and adds:

This was posted on ORARC Facebook page because we want the best result for Bill ZCV and too many cooks spoil the broth but any help and assistance will be appreciated by Bill’s family.

This is the link for you to access to gather any material you would like to post on any editorial on the clubs home page  or email the membership – Oxley Region Amateur Radio Club Facebook Page/Photos/Albums/2 August 2016

Regards … Keith

Ashley Anderson You’re welcome to distribute the photos and information wherever you see fit. The purpose is to let as many people know as possible so that everybody gets to the chance to pick up some equipment for a good price while helping Bill get the best offer for his equipment.

This method has worked very successfully in the past.
We used this method at the Tamworth club and opened it to everybody to make an offer. We had no time frame on the bidding and the final offer would be considered when there was no more offers on the item.

Port Mac is obviously not a destination people can visit just for a garage sale, so for those who cannot attend they can make an offer via the photos on this page.

Please direct any queries regarding the above information to either vk2fkja@exemail.com.au or enquire via the Facebook group.

HP museum and its prized 2116a 16-bit computer lives on as legacy of mountaineer Jon Johnston

From the ABC, original post here.  By Simon Leo Brown, 774 ABC Melbourne.

HP Computer Museum founder Jon Johnston died while trekking in Tibet.

A keen mountaineer who died trekking in Tibet has left a rare computer collection behind as his legacy.

Surrounded by bushland in the eastern suburbs of Melbourne is a wooden shed with barn doors.

It closely resembles a shed in California where, in 1939, Bill Hewlett and Dave Packard launched the company that would become HP.

The much larger Australian shed is home to the HP Computer Museum, filled with ageing computers, printers and calculators, most of which are a dull light grey.

“Dove grey, very hard to get these days,” former HP technician David Collins said, adding that HP had released a few machines with red panelling “but it never caught on”.

The museum contains computing equipment released by HP between 1966 and 1991.

Mr Collins has taken up the challenge of fixing some of the older malfunctioning equipment, but he was not the one who amassed the collection.

It belonged to Jon Johnston, an American-born former HP employee who moved to Australia in 1989 with his wife Sue.

Many of the items he collected from clients who were upgrading their equipment, at first in his role at HP and later while running his own company selling HP products.

‘Revolutionary’ computer to turn 50 years old

Mr Collins first met Mr Johnston last year.

“As I started to have a little bit of spare time, with my kids getting a little bit more independent, I reached out to Jon knowing that he was literally just around the corner from where I lived,” Mr Collins said.

“He had all this great equipment in his museum, and from the [museum’s] website I could see that some of it needed fixing.”

He said Mr Johnston gave him a few minor, expendable items to repair — “in case I messed them up” — before suggesting he attempt to repair the museum’s most prized possession, the HP2116a.
