June Presentation – Microcontrollers
and Ubiquitous Computing
Last
Wednesday night saw a fantastic
presentation from Patrick Burns VK7FPJB who is undertaking his Computer
Science
PhD project and is sponsored by the CSIRO.
Patrick’s
PhD is researching how to
use technology to be more physically active.
Patrick
took those assembled through
the different research that has been done thus far along with reference
to the
current technology like Nike iPod, Wii, Garmin Forerunner, Pokewalker,
gaming
interfaces, persuasive computing and ambient displays. I think the
interesting one
was the toaster that toasts today’s weather onto the toast. This is the
concept
of using everyday things to convey information.
There
has been much research into
conveying information through ambient displays on a team and individual
level.
Patrick
then displayed and took us
through the ActivMON or the wearable Ambient Activity Display which is
the size
of a large wrist watch and it have accelerometers, Bluetooth and a
ultra low
power microcomputer with a Lithium Ion thin film battery.
Patrick
took us through the devices
on this board along with the design, construction and manufacturing of
these
boards.
With
some interesting programming
Patrick takes the accelerometer (Activity) data and sends it to a clock
(via Bluetooth)
which has a ring of tricolour LEDs which pulsate and change colour
based on the
data that is being sent to it.
Patrick
demonstrated that the clock
colour slowly changes as the activity level us built up until you reach
your
goal and the clock magically goes Blue.
This
was a fascinating presentation,
thanks Patrick and we look forward to hearing about how it progresses
over the
coming years.

Introduction
to Geocaching
We
intend to run an introduction to
geocaching for anyone interested.
Do you
have a GPS or a smart phone
that has a GPS and wondered what you can do with it? Well geocaching or
world-wide treasure hunting using your GPS may interest you.
We
will have a some presentations to
explain the basics then we will actually go and find a few caches
around the
Queen’s Domain.

Wintering
in Antarctica - A Retrospective
Our
May Presentation saw a wonderful presentation
from Alan VK7KAJ.
This
was a retrospective look at
wintering in Antarctica over 5 expeditions.
Alan
Jeffrey VK7KAJ spent five
winters in Antarctica as a radio technician at both Mawson and Davis
stations.
Alan’s
talk and slides were focussed
on the radios that were used over each expedition and the maintenance
and
unique conditions that Antarctica presents to the Radio Tech.
In
comparison with last month’s
presentation of the communications systems in place today at the
Australian
Antarctic Division there was much contrast with mainly HF and Telex
over HF
being used for much of the communications with both Australia and South
Africa
for the delivery of meteorological data and rad-phone services.
Frequencies
from 4040kHz up to 22MHz
were utilised from 10kW transmitters at Mawson and 1kW transmitters at
Davis
into Rhombic and log periodic antennas to get signals through.
Alan
also gave an idea of the living
conditions and some humours activities and events.
A
great big thank you to Alan for
sharing his experiences.
The
presentation was videoed and will
be shown in a future DATV night and go into the DATV library.

REAST Activity for the
National Field Day
REAST
set up a station
on the lawns of Salamanca Place and operated VK7OTC.
It was
a magnificently sunny day with
a sprinkling of autumn leaves over the lush grass.
WICEN
came along and helped make the
day an even greater success. We had some visits from amateurs
from both
VK and overseas who popped in to say G'day as well as many curious
onlookers,
some were even brave enough to come over and take a look and have a
play!.
The
day started off with a group of
budding film makers asking if we minded if they used us as props to
shoot
documentaries as part of a film makers workshop they were doing, so we
busily
worked away on the radios and answered many probing questions whilst
being
filmed and interviewed.
Sam,
VK7FSTL is waiting for his call
up for a logie, hihi.
A fun
day was had by all.

Antarctic
Telecommunications
Wednesday
6/4/11 was a fantastic
night at the Australian Antarctic Division Headquarters at Kingston. We
had
about 25 people come along.
The
presentation was given by Peter
Yates VK7PY who is the Telecommunications Manager and Ian McLean VK7IM
who is
Senior Technical Officer who run telecommunications for the Australian
Antarctic
Division.
Peter
started the presentation with a historic flavour at Macquarie Island
and the 1912 communications base established for the Mawson
Expedition and
showed what is currently on the Wireless Hill site.
Peter
then moved to the latest
satellite communications using the InMarSat BGAN – Fleet Broadband
service via
the IntelSat satellites over the Pacific and Indian oceans. This forms
the
ANARESAT network with bandwidths of 768Kbps into Casey, 512Kbps into
Davis and
Mawson and 384Kbps into Macquarie Island. The provision of these
service costs around
$700K per year.
These
satellite service provide IP
services for both networking and voice over IP. This supports the bases
and the
Aurora Australis. Much work has been done to reduce the size of files
and
emails to ensure efficient use of the network and the reduction of
un-necessary
traffic.
http://www.antarctica.gov.au/webcams
The IP
telephony uses the open-source
Asterisk IP telephony solution which runs on a Linux platform and
provides
seamless telephony services across all Antarctic bases and HQ in
Kingston.
Node
controllers (fanless PCs running
Linux and Asterisk) USB to analogue/serial interfaces are used to
interface
with the various radios services. The radios are all Australian! The
airband
radios are XCOMs from Queensland, the HF radios are Barretts and the
VHF are
Spectra Engineering from WA.
The
software engineering was written
by Ian and has evolved over the last few years. Ian demonstrated the
service
via the touch screen interfaces and contacted someone at Mawson based
via VHF
at the base back through the system to Kingston. The system has many
great features
which Ian took us through.
Following
the talk Peter and Ian then
people through the NOC or the Network Operations Centre which monitors
all the
networking, traffic and connectivity through the AAD network.
A
great big thank you to Peter, Ian
for the presentation and to Warren VK7FEET and Paul VK7PAH who
organised the presentation.
The
presentation was videoed and will
be shown at a future DATV night and be placed into the DATV Library.

Meet the Voice BBQ -
Wrap-Up
I am
sure that he many Amateurs who attended
the "Meet The Voice" gathering at Ross last Sunday must have been
satisfied with the day, there were 73 Amateurs registered, I do not
have the
numbers of other guests, but tank you for your contribution to a very
successful
day.
Congratulations
to Frank Clark VK7CK
who received an award for services to Amateur Radio over the past 25
years, and
also to Dick Van Beek VK7DIK who was presented with an award for his
services
to Amateur Radio on the West Coast, and Amateur Radio in general.
The
Sewing Circle Shield for 20122-12
was presented to Scott VK7NWT previously VK7FTTT from Sisters Beach by
Cedric
VK7CL the 2010-11 holder. A very popular choice thank you Cedric.
Our
raffle of SWR meter, 2 meter Hand
held transceiver, Capacitance meter, a lovely men’s jacket and 6
bottles of
wine was well supported and the 5 winners were grinner's as they left
Ross for
home. Thank you to the donors of the various items for your support.
The
proceeds of the day from your registration
and support of the raffle returned $496.00 dollars to the Radio
repeater group
on the North West Coast to be put to repeater maintenance. This money
raised
will go to the Northern group in 2012 and the Southern group in 2013.
Over
the five years of the "Meet
The Voice" day, you have assisted these groups to approximately $2000.
In
the five years we have not had any debits for expenses. The generosity of those
responsible for organising the day is very much appreciated.
Thank
you one and all.
"Meet
The Voice" will be on
again during the third week end in March 2012, at Ross. Make the note
in your
diary.

Software
Defined Radio
The
Future of Radio Presentation
Last
Wednesday night saw a great
roll-up of interested people to a talk on Software Defined Radio by
Richard
VK7RO and Justin VK7TW.
Ric
kicked off the presentation with explanations
on how traditional phasing rigs worked using dual double balanced
modulators with out
of phase audio modulation and out of phase carrier oscillators to
produce both
side bands without carrier. Richard then outlined the alternative of
crystal
filters and some of the issues involved with this type of filter.
Phasing was
developed originally as a cheaper alternative however early in the
development
of phasing it was only possible to get about 40dB of suppression and this
was
OK for a transmitter but was not sufficient for receivers until the
development
of the four phase receiver. These phasing receivers offered 40-60dB of
opposite
side band suppression and Richard showed an early 4 phase receiver he
homebrewed.
Richard
then went through the
advantages of digitising the signal through DSP methods and how easy it
was
then to manipulate phase and amplitude and filter out unwanted signals.
Rich then
showed his softrock and Genesis SDR receivers to those assembled.
The
presentation then moved to Justin
who took people through some of the I&Q terminology and how it is
represented then showed some of the SDR’s available, the difference
between the
quadrature sampling detector and the zero IF direct down convertor.
Justin then
took people through the HPSDR architecture, software and how it has
been
created.
Justin
finished of the presentation
with a demonstration of the PowerSDR and KISS Konsole software
connected to the
HPSDR which was on the club’s trapped dipole.
The
presentation was videoed thanks
to Warren VK7FEET so, this will be put into the DATV library and will
be played
in a future DATV night.
Thanks
to Richard and Justin for this
fascinating talk.
