The
Presidents Pleasurable Words September 2004
Welcome home to our Olympic traveler,
John we hope you had a great time in Athens. Now it is straight
back to work and a club mag to prepare. Members can look forward
to see and hear of some of what went on in Greece when John
gives us a talk at our November meeting.
Our
other exciting news is that on August 21st the two halves of
our club room project was successfully moved from the construction
site at Drouin West and fitted together neatly at the rear of
the Cranbourne Guide hall. With the main gates into the compound
removed from their hinges the truck driver reversed the building
through the gap with a couple of centimetres to spare. His maneuvering
of the units onto the prepared pads was almost a work of art.
Me thinks he had done that sort of thing before. With the fences
and gates now in place, and most of the ceiling tiles in place
the major work that we can do is over. There are a few joints/holes
that need filling and some painting to complete but we have
reached the point of calling in the plumber and electrician
to connect to the various services. Once this has been done
we can advance to the fitting out stage and install the radio
equipment antennas etc.
Rather
than large working bees, Ian will need volunteers in twos and
threes from now on to finish off the remaining odds and ends.
Mike
Ide will chair the September meeting as I will be away house
sitting in Ballarat there may be an opportunity on this night
for an inspection
of the work done so far.
The
committee are in need of ideas for next year's Labour Day weekend
away, if you have a favourite area or camping spot then let
someone on the committee know.
JOTA
time is fast approaching (Oct 16th) David VK3XMF is co-ordinator
for this event. The Guides would like the radio's working between
1300 and 1700 Hrs on the day so if you can help please see David.
It is much easier for you to offer than for him to have to ask
around.
That
is enough from me for this issue, keep the club event queue
close at
hand and know what's going on.
73s Peter.

SHACK PROJECT

MISSION
ACCOMPLISHED!
After
seven intensive working bees by Club Members, were finally successful
in completing the Club Shack building and moving it from the
Drouin West construction site to the resting place in Cranbourne.
The
wall cladding is a polyester coated plywood which required careful
cutting before being glued and nailed into position. Geoff VK3
HGG and Graeme VK3BXG (right) prepare to make an incision.
The ceiling
and workbench bulkhead have been lined with polystyrene ceiling
tiles to provide a bright surface with some auccustic softening
properties.
Club
President, Peter VK3VB is shown here squeezing in some extra
panels. To the right can be seen the bulkhead which runs the
full length of the building to provide ventilation, coax cable
access and workbench downlighting. The front panels may be lifted
out for service work.
When the
last of the interior lining was fitted and kitchenette cupboards
built, each half of the building was carefully braced and prepared
for transport.
One
additional working bee at Cranbourne saw the preparation and
pouring of the concrete foundation pillars to support the building.
This was done with plywood formwork that was later removed after
the concrete had cured. Because of the strong 250mm high I-beams
built into the underside of the shack, it only needed to be
supported at six points for adequate support.

A crane-truck was used to collect the building in two halves
and deliver it to Cranbourne. It was a powerful vehicle that
had no difficulty in handling the structure. At the Guide hall
it passed through the driveway gates with only 20mm to spare
on each side, which revealed great skill by the operator.

Albert VK3BQO, Mike VK3KTO and Peter VK3VB assist in placing
the first half of the building in its resting place.
The
two halves of the building joined up quite well and have since
proven to be sound and waterproof.
Two of the six skylights the building has can be seen in the
above picture. There are no windows in the building. As soon
as both halves were in position, a cyclone style security fence
was erected around the perimeter . A double gate with push-button
combination lock has been fitted to the outside fence which
will allow members to gain entry without having to carry keys
around. A soon as power is connected, an RF-ID key-fob system
will be introduced to allow members to have regular building
access.
This
week Allan Saunders, a local plumbing contractor, will commence
the installation of all the water and drainage requirements,
including a small hot water service and the toilet.
The
final photographs are yet to be made available, but these will
be included in future articles. It is a great testament to the
tenacity of Club members where more than half of the membership
were directly involved in its construction. With a tight budget
of around $16,000 total, we will have achieved the services
of a brand new, fully functional communications shack and project
room. 10.4 metres long and 3.4 metres wide.
Many
thanks are also due to councillors and staff of the Casey shire
for their financial assistance, which has made he difference
between an ordinary project outcome and an outstanding one,
where all of the desired features could be implemented.

ACA blueprint for spectrum management
The Australian Communications Authority (ACA) has provided
an insight into its thinking and policy approach to the management
of Australia's radiofrequency spectrum. In a document entitled
From DC to daylight-accounting for use of the spectrum in Australia,
if outlines the available spectrum resource, its users and the
pressures for access to it. It describes the main uses of the
radiofrequency spectrum, how those uses might be affected by
change and the key challenges faced by the ACA as it tries to
accommodate an increasing demand for spectrum.
Among the
new uses are wireless applications to meet consumer demand for
broadband and cordless communications. In some cases spectrum
will need to re-allocated after migrating existing users elsewhere,
dynamically shared by different users through technology such
as spread spectrum, or sold as blocks through spectrum auctions.
The ACA
report, in referring to the Amateur Service, notes the decline
being experienced in licence numbers in Australia and overseas.
Overall about 5% of the spectrum is allocated to the Amateur
Service. Where there are secondary allocations the ACA said
that the Amateur Service may need to vacate in preference to
other users - with this now occurring at 420-430MHz and 3.4
and 3.5GHz.

New phone technology
A Melbourne-developed technology is set to allowing users
to talk for free over the Internet, any time, anywhere. Freshtel,
at Surrey Hills in Melbourne's east, is beginning to market
its Firefly 'softphone' $89 handset that uses any broadband
or asymmetric digital subscriber-line Internet connection.
While the
Internet phone system using Voice over Internet Protocol (VoIP),
Freshtel's phone has been acclaimed for delivering clear sound,
being easy to set up and activate. Industry experts believe
that VoIP technology will quickly compete with standard telephone
exchange phones. Telstra plans to offer VoIP to homes which
have access to broadband early next year and Optus will follow
suit.
The advantages
of the Internet phone includes cheaper calls, group voice messages,
and free conference calls for up to ten people. The September
issue of Silicon Chip magazine has a feature article on VoIP
that currently accounts for 4% of overseas telephone calls but
expected to increase ten-fold over the next three or so years.

ACA consultation methodology revealed
It was with great enthusiasm the amateur radio fraternity
received the Australian Communications Authority's discussion
paper 12 months ago on its Review of Amateur Service Regulation.
The outcome of the review will undoubtedly provide a number
of benefits for amateur radio in Australia before the middle
of 2005.
However
there is continuing disappointment being expressed over the
Foundation Licence that as proposed, does not meet the expressed
expectations of the majority of those who made submissions to
the ACA inquiry. In answer to correspondence, the ACA has revealed
that it sought to achieve, what it calls an overall integrated
package of proposals. In doing so it was not necessarily influenced
by the number of submissions it received commenting on a particular
issue.
The ACA
review of the Amateur Service was primarily to deal with matters
arising out of the World Radiocommunications Conference 2003.
But it was also recognised as a once in a generation opportunity
to address the underlying issues that are causing its decline,
and take action to make amateur radio more attractive to a wider
range of people. The review was a chance to respond to the challenge
of finding ways to revive amateur radio in Australia, give it
a new life, meaning and relevance to today's societies.
The Foundation
Licence, as proposed will provide no foundation or underpinning
for amateur radio in Australia. Despite the overwhelming support
through the submissions received during the ACA inquiry for
this new entry level licence to have all transmission modes,
the ACA has not listened. It chose to create a telephony and
Morse code telegraphy licence only.
The amateur
radio fraternity sees the desperate need for change and has
embraced a different approach to licensing that reflects trends
that have developed in education generally. The ACA in deciding
to place enormous restrictions on the Foundation Licence won't
help amateur radio integrate in to today's educational and social
climate.

CB stands for Church Broadcasts
An unusual development in Britain is a proposal to allow
churches and other religious groups to broadcast on the British
27MHz Citizens' Band. The regulator Ofcom said it was proposing
to allow Community Audio Distribution Systems (CADS) access
to the band under licences allow them to broadcast religious
services.
Ofcom will
initially allow a limited number of licences. This is in response
to requests for access to radio frequencies so that house-hound
members of a religious congregation can hear local religious
community services.
CADS will
provide an inexpensive wireless public address system that Ofcom
believes may also be of interest to other community groups.

EMR audits for radio amateurs
The electromagnetic radiation (EMR) limits that govern the
operation of amateur stations are now being put to a compliance
audit by the Australian Communications Authority. The ACA now
conducting an audit by writing to randomly selected amateur
licensees, in the first of what will be an annual auditing process
of compliance with the EMR limits.
Those limits
that apply to all apparatus licensed transmitters became effective
on 1 March, 2003, and the Amateur Licence Condition Determinations
have been amended to include this new regulatory requirement.
They are designed to ensure that a transmitter is operated at
safe levels for general public exposure to radiation. The ACA
is required to conduct an annual audit of compliance with the
EMR limits set out in the Radiocommunications (Electromagnetic
Radiation-Human Exposure) Standard.
It will
write to 30 or so radio amateurs throughout Australia to request
that the licensee attests that their station is operating within
the EMR limits, and explain how its meets compliance under the
self-assessment method. This applies not only to home stations
but mobile and portable stations too. The radio amateurs receiving
the letters are chosen at random.
A failure
to respond to the ACA letter or an inadequate response will
result in the ACA initiating follow-up action to enable it to
complete the audit. The EMR requirements for amateur stations
were included in the February 2003 edition of Amateur Radio
magazine, and can be found on the ACA web-site http://www.aca.gov.au/
Remember that it is a licence obligation that amateur stations
or all types be operated in accord with the EMR limits.

VHF profiler RADAR
Profiler RADAR operating on 50.000MHz may be the source
of continuous dahs reported in the northern hemisphere. Atmospheric
profiling RADAR has known test sites in the United States, Northway,
Peru and Russia. Accomplished six-metre DXer, Steve Gregory
VK3OT reports that all of the test tests have high powered 50
MHZ radar transmitters, some with as many as 475 yagi antenna.
First reports of signals from the radar systems radars began
to be recorded by radio amateurs on 27 July in the US and Canada.

New
radio club gets on AIR
The 417
Squadron of the Australian Air Force Cadets based in the southern
Melbourne suburb of Sandringham has set up an amateur radio
station under the club callsign of VK3AIR. Their leader Theo
Kalkandis VK3AP reports that 16 cadets recently took part in
the Radio Telephony exercise comprising of basic antenna theory,
propagation, and radio operational procedures.
About six
of the cadets are keen and showing some interest in the Foundation
Licence that is to be introduced around April next year. Theo
VK3AP says the 417 Squadron is the first Australian Air Force
Cadets to have an amateur radio club station and he's seeking
to encourage other squadrons to follow suit.

Trying
for a new ATV distance record
Attention all involved in the higher bands in a radius of
200 kilometres or more from Melbourne. In announcing his plans
for next summer, Jose Martinez VK3TMS wants to hear from anyone
willing to try some frequency modulated Amateur Television on
any band from 1.2GHz up to 10GHz. He intends to operate from
Mount Dandenong east of Melbourne when good propagation is likely
during the summer months - and who knows perhaps a new ATV distance
record could be set.
The Australian
distance record on 10GHz is currently 144.3 km. In the spirit
of amateur radio Joe VK3TMS is willing to provide some assistance
to anyone who can provide the other end station of a potential
distance record.
If you
would like to know more please send an email to vk3tms@optushome.com.au

Inventor of ASCII passes
The man who invented the ASCII code and predicted the Y2K
problem has died aged 84. Bob Bemer first warned of the Y2K
or millennium bug problem in the early 1970s. He began programming

Do you hear the Echo?
The "Echo" satellite (AO-51) is now available for FM repeat
operation for a trial period of about three weeks. Launched
on 29 June the AMSAT North American microsat in a sun synchronous
orbit 800km above earth is set to bring a new dimension to amateur
satellite working.
Working
through Echo during the trial period may be difficult because
the downlink is initially running about 1-watt and wobbling
is affecting signal polarisation. The voice uplink frequency
is 145.920 MHz, and the downlink is 435.300 MHz.
AMSAT-NA
says the repeater will function when it receives an uplink signal
with a 67 Hz CTCSS tone for about one second, and it will stay
on for 10 seconds after that signal goes away. The organisation
reports that a lot of work is continuing to be carried out by
command stations who are monitoring the repeater's data and
making adjustments.
While the
FM voice repeater is working, its digital transponder and the
store-and-forward BBS, are not yet available. Echo AO-51 which
cost the $US110,000 to launch is also sending telemetry on 435.150
MHz

Somalia
is on the ham bands
The efforts of an Australian has help achieve a restoration
of Amateur Radio in the African country of Somalia. Sam Voron
VK2BVS/6OZA is continuing to supervise an Amateur Radio Training
School and through the use of donated equipment is helping to
qualify as many locals as possible.
Two club
stations in the town of Galkayot. Some 17 local hams were qualified
in the technical training provided in 1993 to establish Radio
Galkayo, Somalia's only community radio broadcast station, but
they had no access to an amateur transceiver until recently.
The first station uses a TS820 transceiver donated by Cherry
Briggs, the widow of Philip John Smith VK1GZ who died earlier
this year after a long battle with cancer. It is on air 0330-0400
and 1230-1400 UTC on 14.266MHz and also available is 21.295MHz
and 28.475MHz.
The second
station uses a Yaesu FT857 transceiver donated by Sam Voron
VK2BVS. Prime times are 1645-1815 UTC on 18.150MHz and also
available is 1.847MHz, 3.620MHz, 7.070MHz, 14.130MHz, 14.226MHz,
21.295MHz, 28.475MHz, 50.110MHz, 50.125MHz and 144.100MHz.
Donated
equipment is now being sort to enable the setting up of the
Somalia Amateur Radio Emergency Network to provide an emergency
network across Somalia. Naturally news of Somalia being on air
has created a demand for QSL cards, which unfortunately is currently
out of the question for the locals due to the costs involved.
Sam VK2BVS says visitor licences are now available and hopefully
a DXpedition can be mounted to satisfy the pent up demand for
QSLs.
He will
leave Somalia at the end of September and can be contacted via
email svoron@hotmail.com In the future it is expected that radio
amateurs will hold elections for the National Somalia Amateur
Radio Society to further consolidate the return of amateur radio
to the country.

A Suggestion
for an Internet_Based Amateur Radio Station
By John L WICKHAM VK3ZK
Are you
plagued by neighbours complaining about TVI or has your landlord
forbidden you to erect an antenna system? Perhaps, the Internet
might hold an elegant solution.
Imagine
a property located deep in the bush, far away from power lines
and far away from TVI-complaining neighbours with a massive
antenna farm and batteries of transmitting and receiving equipment,
operating on all legal amateur bands from 160 Metres to 13 Centimetres.
The amateur radio licensee suffering from TVI complaints and
un-sympathetic landlords could then work all bands from DC to
daylight, using this remote deep bush-located amateur radio
equipment via Internet streaming audio on similar lines to both
EchoLink and the IRLP project (if such licensee has a broadband
Internet connection).
To fund
such a project, the WIA and as many amateur radio clubs as possible
could contribute (although such interested amateur might have
to pay slightly more for their membership). Sponsorship from
some of the bigger amateur radio equipment suppliers would help
also.
But what
about the radio pirate element? They can be easily stopped dead
in their tracks by using a system similar to what EchoLink does.
When you use the required software for the first time, you would
have to enter a valid amateur radio callsign, which is checked
against a database. If your callsign is not valid, you simply
will be granted no access to the facilities. However, for this
kind of scheme, if you fail to supply a valid callsign, you
could be granted receive-only rights and you will not be able
to transmit until you supply a valid callsign.
To ensure
that the funding is there for such a project, you might also
have to enter a valid receipt number to prove that you have
contributed to the funding of such a project.
Whilst
some might think that such a project is a little bit too extreme,
it is not for-fetched because we have the technology today to
achieve it (Just look at the IRLP project and EchoLink as an
example). You would, however, need approval from the ACA and
the support of the WIA to make it feasible.
