NATIONAL NEWS FOR WEEK COMMENCING APRIL 23 2017.
IN OUR 22nd YEAR OF NON STOP NEWS
WIA AGM Convention will have something for everyone
THIS STORY AND MORE IN THIS EDITION OF NEWS FROM THE WIRELESS INSTITUTE
OF AUSTRALIA 2017 AND FOR WEEK OF APR 23
Satellites built by Universities launched into space by NASA
The first Australian-built satellites in 15 years have been launched into space
by NASA after being developed by Australian universities
One of the miniaturised satellites was built over four years by about 50
University of Adelaide (UOA) staff and students.
Paul ex VK5FPAU who now lives in the USA and sent us this story says it is
one of three "nanosatellites" developed in Australia as part of a research
project involving Australian universities under the European-funded project,
QB50 an international network of 50 CubeSats.
Lifting off from Cape Canaveral on Wednesday they are part of the initial
28-satellite strong QB50 mission of CubeSats involving 27 countries.
They will play a key role in investigating the thermosphere a layer of
atmosphere from about 95 kilometres to 500 kilometres from the Earth's surface
with the aim of increasing understanding of climate and weather modelling.
Australian universities in Sydney, Canberra as well as South Australia had
their satellites rocketed for deployment from the International Space Station
and should be deployed in May and June.

Clarence Valley Amateur Radio Group
Who are the Clarence Valley Amateur Radio Group (CVARG) you asked?
Writing in the Summerland News Letter, Maeva VK2FMWL, says they are a mixed and
dynamic group of Hams (32 at last count) thoroughly involved in and enjoying
the hobby. They have been active for around 12 months on the VK2CLR repeater
and stress they are a group, not a club.
The group have regular Monday evening nets at 8pm discussing a wide variety
of topics, sometimes themed, sometimes free for all and not always totally
ham related. The net is very well attended, generally up to 12 taking part
with members taking turns to control the chat.
CVARG use the VK2RCV repeater in Grafton.
Outside of the nets various members can be heard swapping information, yarns,
and generally helping each other out. The group has a Facebook account where
news and happenings are freely shared.
Another feature is the social activity based around a Saturday lunch with
show and tell at the Brushgrove pub being well attended, a fun way to while away
an afternoon. The 'Brushie' is central to both the 'lower' and 'upper river'
members, so very convenient for all.
VK2FMWL says the trip across the Clarence River on the ferry is a novelty.
The membership is spread over a fairly wide geographical area. On air activity
John Moyle and the ILLW to name just two, are actively engaged in with several
group members achieving excellent numbers.
Clarence Valley Amateur Radio Group, PUTTING THE WOW (Thanks VK5) back into

While you have your diaries out, BARG also are having an auction on May 28
at their club rooms starting with a soup lunch from 12 midday with the auction
due to start at 1300.
It is a fun day where you can dispose of your unwanted bits and pieces which
maybe of value to other amateurs.
So start putting together your "lots", remember that it is open to all comers
to bring and buy or sell.
Tony VK7VKT took possession last week of a complimentary FlightAware
Raspberry Pi ADS-B decoder supplied by Flightaware, along with a 600mm 1090mhz
antenna and accessories.
Flight Aware are actively seeking out persons wishing to host a ground
station. The cost is zero. They have several persons in the state volunteering
their data from various devices but are keen on achieving MLAT accuracy by way
of having more of their custom devices as ground stations in areas lacking.
A free T-shirt was also part of the deal, HiHi.

Again the event will be held at the old Alice Springs Telegraph Station in
WIA BOARD TALK
WIA AGM convention has something for everyone
Hopefully by now you have booked your place to attend the WIA AGM
Convention at Hahndorf South Australia on the weekend of May 19-21.
The business of the AGM was notified in the March edition of Amateur Radio
magazine. Material will be made available to financial members of the WIA.
The more than 100 people for the AGM on May 20, need to register for
entry which begins at 8.30am Adelaide time.
Those attending the AGM will get a copy of the 20 page history booklet
'Some South Australian Experimenters, Their Activities and Legacies'.
The weekend also has the launch of the new book Wireless Men & Women @
War and a new iPhone application for portable activation alerts.
On Saturday afternoon will be technical talks followed by a traditional
dinner on Saturday night, and on Sunday an array of outdoor activities
Please read the full program details on the WIA website that begins on
Friday evening with a social gathering and use the booking form.
Now again this week to Grant VK5GR with some more news about the events planned
for the WIA AGM & Convention to be held in Hahndorf in May.
"I'm here today with two of our guest speakers, David VK5KK and Iain VK5ZD
who will be talking to us about amateur microwave communications.
Iain, first of all, how did you get started in microwave and what sparked
your interest? "
I started playing with microwaves in the mid '80s, I came across a
device called a gunnplexer operating on 10GHz and we did a lot of
playing around with those things, and managed to make some contacts
up to 100km. So, that's where I got going with it.
And David, how about yourself?
Mine was probably mid late '70s when Reg Galle VK5QR was playing around
with microwaves across to Wally VK6WG and I built a 1296MHz transverter
essentially, in the late '70s and managed to work VK6KZ and hold the
world record for about 2 days so that's how that started.
That sounds like a very interesting way to get into it.
So if others wanted to get started in microwaves, how hard is it?
What have they actually got to do?
Well, it's not that difficult actually, it does really come down to what
sort of budget you've got but there's things to suit everybody. There is
an awful lot of surplus equipment out there which is available, there
are plenty of kits around that you can also build to get yourself going,
essentially you need a transverter and a standard VHF/UHF transceiver in
front of it, so it's not particularly difficult. There's a little bit of
hardware involved setting up antennas and things like that but no more
complicated than getting going on 2m or 70cm, just that they all look a
little bit different that's all.
Now David I understand we are planning something a little bit special on the
Sunday, what can you tell us about it?
Yes, we are going to activate Grid Square PF94 on 10GHz EME, which has
not been done before, so VI5WOW will be on 10GHz EME on JT4F. We have a
couple of stations, probably 4 that we can work, but 2 - HB9Q and OK1KIR
both capable of working us with our 3ft dish.
So come on down to the Amateur Radio come and Try day at Hahndorf Oval and you
will get to see 10GHz EME in action. Now, that will be taking place up until
about 2pm I understand?
That's right. We will have access to the DB0EME moon bounce beacon from
about 12.30pm to about 2.00pm, the limiting factor is the tree line but
effectively between 1-2pm will be the optimum time.
Thank you very much guys for talking with us and we look forward to seeing
everybody coming down to the WIA AGM & Convention in South Australia, to find
out more about microwave communications. Thank you very much!
This has been Grant, VK5GR with David VK5KK and Iain VK5ZD for the
WIA AGM & Convention 2017 organising committee! See you between
May 19th and 21st !

Apollo 11 Capsule Going On Road Trip
To accommodate the Smithsonian renovation of its gallery at the
National Air and Space Museum in Washington, the Capsule will visit
four US cities.
The four city tour will include Houston, St. Louis, Pittsburgh and Seattle
as part of the a new exhibit: "Destination Moon: The Apollo 11 Mission".
ON THE FRONT PORCH OF RADIO HISTORY
For a little bit more radio history, this week we head to New York State's
Hudson Valley, where dots and dashes are taking centre stage. Or at least.....
the front porch.
Amateur Radio Newsline's Heather Embee KB3TZD says the Samuel Morse estate
in Hudson Valley was the summer home of the noted inventor and 19th century
The historic house and grounds, known as Locust Grove, is marking the 227th
anniversary of Morse's birth by doing the very thing Morse himself made
possible - communicating in code. On April 29, the Hudson Valley QSY
Society will be operating in CW from the porch of the old house, making
radio contacts in Morse Code to demonstrate to the public how effective
a mode it still is.
Guests at the home will also be welcome to visit the historic home's
telegraph gallery which contains reproductions of early electromagnetic
telegraphs similar to those developed and used by Morse.
Hams, as we all know, are accustomed to being prepared - we assist at
marathons and half-marathons, we provide a communications safety net
at boating and horse riding events, hiking events and cycling events.
So in Maldon, England, when the Essex RAYNET was called in to assist at
a fundraising fun run around Maldon Promenade Park, the hams there were
prepared. After all, not every amateur gets to assist at a mad dash through
a fortress of coloured bubbles.
Actually, there were four such bubble stations and as the runners came charging
through each, streams of colourful bubbles were shot in their direction, the
thick lather rising as high as 1 and a 1/2 meters.
It was their hottest day of the year so far - and an estimated 1,000 runners
nonetheless turned up to raise money for a local hospice.
The event was sold-out and with the help of Essex RAYNET and its UHF repeater,
it was proclaimed a great success.
No doubt organizers who'd worked so hard got a chance to celebrate afterwards.
Maybe they even broke out a bit of the...."bubbly."
WEIRD AND WONDERFUL
Back in the March 26 WIA National News Service we met artist Jackie Ferrara
whose works feature Morse Code numbers and letters that actually are bricks
featuring in landscaping AND buildings.
Well now Jim VK3PC has been doing a little 'googling' by the look of things
and comes up with this tongue-in-cheek jibe with Morse code
He says a new skate hall building in Oslo Norway is attracting professional and
amateur skateboarders of all ages.
Part of its structure is a cladding of aluminium panels punctured by a
surface pattern of Morse code symbols.
So what does it read?
The architects has some fun with this one, a literal transcription of
the 1978 Norwegian law forbidding the use, sale, and advertising of skateboards.
Of course that law was abolished in 1989 and skateboarding has flourished ever

Radio ham launches over 500 High Altitude Balloons
The ARRL has made available an article about Bill Brown WB 8 ELK which appears
in the May 2017 issue of QST
Bill has launched over 500 high-altitude balloon projects over the span of
30 years. For his first flight on August 15, 1987, Bill designed a remote
viewing platform, using a P.C. Electronics Amateur TV transmitter on 434 MHz,
and a 50 mW, 2-meter FM beacon to track and direction-find the payload (this was
of course, before GPS).
"Amateur TV stations across the Midwest had beautiful reception from this tiny,
1 W amateur TV transmitter as far as 250 miles away," Bill explained.
"The 2-meter beacon was heard over 400 miles away."

Packet From The International Space Station Is Back On 145.825 MHz
The Amateur Radio on the International Space Station Team is

ARISS did the foot work and paperwork a few months ago to launch
the last back-up Ericsson VHF handheld radio to the ISS.
This work was begun in October after the failure of the Ericsson unit
that had been used on the ISS.
The Eriksson's have been operating on the ARISS for 16 years. In the last
days of February, the SpaceX 10 launch vehicle, Dragon, flew to the
ISS with the HT on-board. After the docking, ISS crew members had the
odious job of unloading and unpacking 5,500 pounds of cargo,
including the Ericsson HT.
ARISS got word Friday morning that we now have VHF capability back in
the Columbus module. Followers of ISS Fan Club have already posted
that they've heard and used VHF packet, and are thrilled and happy to
have it again!

More Americans than ever have been licensed by the Federal Communications
Commission as amateur radio operators, and those in the know say that emergency
communications is driving their passion to be 'hams.'
"There has been a tremendous amount of interest in emergency preparedness since
9/11 and Katrina, and this is true for the amateur radio community as well,"
said Mike Corey, the emergency preparedness manager for the American Radio
Relay League. "Emergency communications is a gateway into amateur radio, and
many join our ranks through an interest in being better prepared themselves
and as a way to serve their community."
"This is the third year in a row that the total number of new licenses has
exceeded 30,000," said the ARRL.
