WYP to help promote physics
In a coincidental celebration of Albert
Einstein's "miraculous year" 1905, the United Nations
has declared 2005 the World Year of Physics. Einstein 100 years
ago published several scientific articles that profoundly influenced
understanding of the universe.
They included
the nature of light, existence of atoms, and the concepts of
space, energy and matter. The United Nations Educational, Scientific
and Cultural Organisation (UNESCO) is to organise activities
celebrating the Year throughout the world
New Hamsat ready for launch
AMSAT India is hoping to orbit a new
low earth orbiting satellite in February or March this year.
Weighing 40Kg the micro-satellite will hitch a ride to orbit
altitude with another satellite from the Sriharikota launch
site in the southern Indian state of Andhra Pradesh.
It will have
two transponders, the main unit being Indian and a back-up system
that is Dutch made. Operation will be Mode-B configuration with
UHF uplink and VHF downlink. This mode is also known as U-V operation.
The linear
transponders are designated to operate in CW/USB/FM modes. Uplink
centre frequency will be 435.25MHz while downlink is 145.90MHz.
The beacon frequencies are (Indian) 145.940MHz and (Dutch) 145.860MHz.

More countries
gain 40m band extension
Steady progress is being made in Europe
particularly for their radio amateurs to gain early access to the
7100 - 7200 kHz band for the Amateur Service. The World Radio Conference
2003 decided that the segment 7000 - 7200 kHz will be globally
harmonized for the Amateur Service from 2009.
However, on
the condition that harmful interference is not caused to the
broadcasting service, radio administrations may from 1 January
2005 allow their radio amateurs to have access on a secondary
basis.
Britain, Croatia,
Denmark, Iceland, Ireland, Poland, Norway, San Marino, Serbia-Montenegro,
Switzerland and other nations are giving their radio amateurs
the advantage of this early access provision.

Australia sending
radio receivers to Tsunami-hit areas
Commercial Radio Australia
(CRA), the radio industry body, has taken the initiative
to aid and coordinate the restoration of radio broadcasting
to people in several Asian Tsunami disaster areas.
In a media
release CRA said it is contributing up to 50,000 AM/FM portable
radio sets to stricken areas with the five batch being shipped
to Indonesia and the remainder over the following four to five
weeks.
The radio
industry has also offered a number of engineers to help set up
temporary broadcasting facilities in disaster zones, and up to
seven transmitters will be provided.
CRA Chief
Executive Officer, Joan Warner said the initiative involved the
donation of radio sets, fresh batteries and broadcasting equipment
to survivors and broadcasters affected by the disaster.
Ms Warner
said, "Indonesia's public broadcasters have reported more
than 30 of their employees are missing or feared dead, and many
broadcasting facilities were severely damaged during the disaster.
"Helping
to restore radio communications to affected areas is a practical
way the Australian industry can contribute to relief efforts
and will provide a channel for authorities to communicate vital
information about water, food and medical aid."
CRA has also
gained the support of the Asia Pacific Broadcast Union (ABU),
which represents 130 radio and television broadcasts in 54 countries
and is also asking its members to support the project through
donating radios and broadcast equipment for Indonesia's Aceh
region, Sri Lanka and the Maldives.
One of the
broadcasters that has been affected is Radio Republik Indonesia.
It has managed to set up a temporary studio and AM and FM transmission
facilities in Banda Aceh, but requires emergency broadcast equipment
and a minimum 5,000 portable radios for the homeless.
The Sri Lanka
Broadcasting Corporation has also requested FM radio receivers
for survivors, while the Maldives needs battery-powered radio
sets for eight temporary shelters each housing 500 to 3,000 people.

BPL has doubtful
future: WIA
By Jim Linton 23/1/2005
The Wireless
Institute of Australia (WIA) seriously doubts that broadband
over power lines (BPL) technology can deliver on its promises
while overcoming its radio frequency pollution issues. WIA Director
Phil Wait said, "It sounds like a very good idea in principle,
but we believe it will fall short on implementation."
Mr Wait, who
coordinates the WIA's working group on BPL, was recently invited
to appear on the weekly TekTime program on Melbourne's 3MDR FM
community radio. The WIA is the national society representing
the interest of radio amateurs.
He explained
that BPL had its genesis or beginning in low frequency narrow
band control signals sent down power lines to remotely control
off-peak hot-water systems and telemetry for power distribution
management.
"In the
1980s experiments were conducted in transmitting higher speed
data over power lines and with the recent growth in the Internet
people have been looking at developing another 'pipe' into the
home.
"Someone
found, only a few years ago, that if you pump enough broadband
power down one end of the powerline out in the street something
is going to come out at the powerpoint. And that's BPL as we
know it," Mr Wait said.
The main attraction
of the technology is its potential to overcome what is termed
the 'last mile', the problem of getting cables into somebody's
home.
Particularly
in home units with the building jointly owned through a body
corporate where cabling access permission is hard to get. Because
of this cable-based telecommunications providers do not provide
broadband to those buildings.
The WIA Director
said the bandwidth that has been achieved through BPL tests in
Australia so far is comparable with rates from ADSL cable.
He said "The
very latest BPL chip claims to deliver much higher bandwidth.
But with high bandwidth comes limited range and more susceptibility
to interference. It's the same old story that you don't get something
for nothing.
"There
are two major problems with BPL technology. One is the interference
it generates and is also susceptible to, and the other is the
bandwidth."
Mr Wait said, "The
power lines were never designed to transmit anything like broadband
frequencies. They are full of discontinuities, they've got branches,
leaky insulators and are not shielded an enormous distributive
antenna that runs around a city."
He said that
radiation from BPL has the potential to affect all HF radio users
in Australia such as aviation, maritime, emergency services,
long distance transport, broadcasting and amateur radio. The
Australian Radiocommunications Act and the International Telecommunications
Union radio regulations prohibit telecommunications services
from causing harmful interference to radio services.
During a recent
trial of BPL at Queenbeyan in New South Wales measurements were
taken and confirmed similar results recorded overseas.
Mr Wait said
there's a lot of research on trying to get the interference levels
of BPL down, including the use of 'notching' to reduce certain
frequencies.
However he said the notching is only achieving about a 20dB difference which
is insufficient to protect HF radio users. Mr Wait said interference can also
be a problem for the consumer using BPL technology. It is susceptible to disruption
by radio signals interfering with it. The operation of BPL relies on it sharing
frequencies already used by radio services.
He said, "A
number of tests done internationally show that very, very low
power levels in the order of a few watts can interfere with a
BPL system.
"This
has the potential to interrupt the BPL signal. It will either
slow it down or make it go away."
He said there
were limited BPL trials underway in various parts of the world
and a driving element for them is often a political determination
to spread the availability of broadband access.
"There
is a lot of political pressure in the US to improve the access
to broadband services in rural America. The US is lagging behind
many other countries in broadband penetration.
"President
(George W) Bush has come out and said that he supports virtually
anything that is going to increase broadband," Mr Wait said.
The situation
in America is also interesting because the Federal Communications
Commission has established 'exclusion zones' prohibiting BPL
near government radio installations, obviously in recognition
of the potential for interference.
In Australia
the WIA sees BPL as being attractive to utility companies who
have been looking at ways to 'bundle' services, giving them the
opportunity combine electric supply with a telecommunications
service.
BPL also can
enable power companies to remotely read electricity meters and
achieve micro-level control over their networks in the future.
The WIA believes
that there may be BPL in some areas of Australia. Mr Wait said, "We
will certainty see things like 'homeplug' which is an in-house
distribution system. We will certainty see home-networking within
building using this sort of technology.
"But
I think the reality of the situation when they start to deploy
(BPL) networks they're going to have a lot of problems."
He said there
are a number of trials, and a few commercial trials. Some have
been shutdown for commercial or technical reasons, including
interference. There is still a lot of interest in it.
"BPL
will probably be trialed and may find application in some areas
in a limited way," Mr Wait said. "One of the arguments
being put for BPL is that is it useful in rural areas.
"Well
it may be useful in rural towns but it is not much good out on
remote properties because the cost I believe in getting BPL signal
out there to start with is going to be too prohibitive."
He said the
most encouraging (BPL enabling) technology that is coming out
is wireless such as WiFi and WiMax, with its price dropping and
capabilities rapidly improving.
Another option
for power companies to enter the field of telecommunications
is to string fibre-optic cable under the neutral power conductor,
and then every now and then have a wireless node serving an area.
"BPL
itself is quite a good idea. The WIA is not opposed to BPL per
se, the Wireless Institute is opposed to the interference that
BPL generates," Mr Wait concluded.

New standard
for mains power plugs
Concerns about electricity
safety has prompted a change to the Australian mains 3-pin
power plug. Under the Australian Standard AS/NZS 3112:2000
the active and neutral pins on both 10amp and 15amp power
plugs and plug-packs must be insulated.
This change,
to be mandatory in April this year, has been introduced in response
to a number of incidents including fatalities with un-insulated
pins.
These incidents
involved a metal object, such as a metal blind slat or other
metallic material coming into contact with a plug pin that was
partly removed from its socket.
Insulating
of pins are not new and can be found in use on mains power plugs
in Europe and some other countries.
The Australian
3-pin plug was introduced around 1930 at the time when electricity
generally became available to homes. The Aussie plug is also
known as the Australasian plug because it is used in New Zealand
and Papua New Guinea too.
Apparently
it was copied from the design of an American plug that no longer
exists, although it still survives in Argentina where different
wiring polarity is used and China which mounts it with the earth
pin on top.
Each Australian
State and Territory and New Zealand Electrical Regulator requires
all electrical equipment to be supplied with insulated pin plugs,
at all points of sale, by no later than the 3rd of April.
Amateur radio text messaging
Something new - the
Sound Card Amateur Message Protocol (SCAMP) is promising to
add an email-like text message capability to amateur radio.
SCAMP uses narrow (2kHz) bandwidth HF or VHF voice channels
to transmit text error free using ordinary sounds cards and
modestly powered computers.
It is being
tested in the United States. The first transcontinental exchange
of Amateur Radio e-mail messages using SCAMP took place December
4 on 20m between California and Pennsylvania.
Cordless phones continue to intrude
Long-range cordless phones
that operate on the amateur two metre band are still around and
while there has been no recent reports in Australia, one has interfered
with an amateur repeater in the United States. The Holmesburg (Pennsylvania)
Amateur Radio Club complained to the Federal Communications Commission
about telephone conversations appearing on 146.080 MHz input frequency
of its repeater.
The offending
cordless phone base units was tracked down and its owner surrendered
it to an FCC officer and inquiries about its source are continuing.

Exclusion zone for 70cm band in Victoria
(Oct 2004)
The bottom half of
the 70 centimetre band is no longer available for amateur radio in
most of Victoria as the result of a new exclusion zone
that has just become law through an amendment to the Amateur Licence
Conditions.
The
ACA has prohibited amateur radio activity on the 420-430
MHz band within Victoria in an area of up to a 250 kilometre radius of the Melbourne
General Post Office. That band will now be used for a new
state-of-the-art digital radio system to replace the current
analogue systems of the Victoria Police, Metropolitan Ambulance
Service and Metropolitan Fire Brigade.

BPL interference not confined to HF
(Oct 2004)
Measurements carried
out in Japan clearly demonstrate that interference from a broadband
power line (BPL) system generates spurious RF emissions beyond
300 MHz. BPL injects RF energy along power lines to provide broadband
Internet services into homes and businesses, but it also leaks
radiation as modulated carriers at intervals of about 1 kHz. The
frequencies used are commonly between 2 MHz and 30 MHz and some
proposed systems will extend this to 80 MHz. As the electricity
distribution lines were never designed to carry RF, they act like
an antenna system, and due to the electricity grid not being perfect, intermodulation products
and harmonics are created too.
Japanese
tests detected higher frequency spurious BPL emissions between
310 MHz and 340 MHz at distances of up to 55 metres from a
BPL-enabled power line. Apart from HF communications, BPL has
the potential to interfere with TV and FM broadcasts, VHF land
mobile operations, aircraft VHF communications, maritime VHF
communications as well as amateur 6m and 2m operation. Read

The
National WIA and the Clubs - Working Together
(Oct 2004)
The National WIA
board has received many suggestions from visits to clubs by directors
as to how the clubs and the national WIA might work together more
effectively.
Many
clubs have identified the need to establish an information
flow between the clubs and the WIA. To this end work, has
commenced on linking the WIA website to the club web sites
and providing a complete list of the clubs, when they meet
and how to contact them on the National WIA website as well
as in the next issue of the WIA Callbook.
A
link from the WIA web site to the clubs web pages has now been
provided. It can be entered via the link at the top right hand
side of the WIA home page, and is marked "amateur radio
clubs of Australia".
The
WIA does not have a complete and up to date list of all the
clubs and special interest groups. We need your help to complete
this list. If you are a member of a club or special interest
group, take a look at the entry for your club or group on the
WIA web site and let us know as soon as you can any corrections
or additional information we should add to your clubs listing. All
you need to do is send an e-mail to WIA director, Ted Thrift,
VK2ARA at tthrift@iprimus.com.au listing
what changers are needed.
More
initiatives will be released shortly as the board and the clubs
continue to define how best to work together.

Europe considers Foundation Licence concept
(Oct
2004)
A
new entry level licence is being seriously considered by Europe
based on the British Foundation licence that was introduced in
2002. The Radio Society of Great Britain (RSGB) has been able
to provide an example of how such entry point licensing can work
and this has captured the attention of other European radio societies.
Several countries in Europe have been considering
the introduction of a new licence to make amateur radio more
attractive, but most believe it is essential for it to be achieved
through the common CEPT (Conference of Postal and Telecommunications
Administrations) licence system rather than nation by nation.
A
meeting of European national radio societies has concluded
that a future CEPT Foundation Licence must have a substantial
access to HF, as well as VHF and UHF to show newcomers all
aspects of amateur radio.
All
operating modes - phone and data, should be encouraged by
the licence. The intention would be to get newcomers involved
quickly to build up their interest. Progression from entry
to full licence is a main objective. The next step is to
explore the issue informally with the CEPT and for the European
radio societies to discuss it further at their next meeting.
The
proposed Australian Foundation Licence to be introduced in
2005 is out of step and unlikely to qualify for CEPT recognition
because the ACA has decided to restrict it to voice and hand-keyed
Morse code only. The ACA is also watching overseas developments
closely and may still yet be convinced that an all mode Foundation
Licence is vital for the future of amateur radio in Australia, while also achieving
international licence harmony.

Important
Amateur Radio Issues
Being Discussed At Meetings in Geneva
(Oct 2004)
The long journey
to the next World Radiocommunications Conference
(WRC 07)has started with a meeting of the Working Party 8A of the
Radiocommunications Study Groups of the ITU from September 6th to 15th,
with two important amateur radio questions under discussion.
The
first is an IARU proposal for a new amateur band from 135.7-137.8
kHz. This proposal is moving forward well, and it appears
that there will be support for a new world wide allocation
at the next World Radio Conference in 2007.
The
second is a proposal from the short wave broadcasting community
for up to 850 KHz more spectrum between 4 and 10 MHz. If
approved, the spectrum would have to be given up by other
users, namely the fixed service, the mobile service, the
amateur radio service and the radio navigation service. None
of these are interested in giving up spectrum. The discussions
are well along, but there is no solution in sight.
For
both of the above items, amateurs from Canada,
the USA, the UK,
and Japan are
actively participating. Amateurs from many other countries
are also present but active in other areas.
Later
in September, and during much of October, these same issues,
as well as matters related to BPL, will be discussed by other
groups with different points of view.
In
all of these meetings, Ken Pulfer VE3PU
will be attending on behalf of the IARU, and will also be
a member of the Canadian delegation. He has agreed to provide
the RAC web site with news reports as the meetings progress.

Tasmanian Divisional Meeting Confirms
Moves Towards The National WIA
(Oct 2004)
The special general
meeting held on Sunday, September 19 at Ross to resolve the future of the
Tasmanian Division ratified the VK7 council recommendations. The meeting
passed the special resolutions to apply for dissolution of the Division,
and to pass the surplus funds to National WIA after deregistration is effected.
The Divisional council was duly authorised to dissolve the Branches. The
process will now be administrative, to finalise the financial side of the
wind up, and within a month apply to Corporate Affairs for deregistration.
Two
new clubs have been formed to take the place of the Northern
and
Southern
Branches. These are respectively Northern Tasmanian Amateur Radio and Electronics
Group, and Radio and Electronics Association of Southern
Tasmania Inc. It is expected that a new club to be formed
in the North West of the state in the next twelve months.
Both of the new clubs will apply to affiliate with the
National WIA.
The
Southern Tasmanian Association has agreed to host the records
of theDivision and other historical documents, as it has storage
facilities. As the old Branches were formerly dependent on
the Division to supply a number of services some seed funding
has been necessary to make sure that they will be financially
viable. This has the effect of reducing the surplus payable
to National, but members felt that in the long term it will
ensure the strength and continuity of the clubs and ultimately
of the WIA in Tasmania.
Phil
Corby, Tasmanian Divisional president reported he was personally
pleased to
see at the meeting many who have been long time members and
supporters of the "Institute" as the Tasmanian
Division was usually called. He added that he felt that this
show of support augers well for the future for the National
WIA.

BBC
Expresses Concern Over BPL Rollout
and it's Potential Interference to Digital Broadcasting
(Oct 2004)
Fears for New
Digital Radio System
By Chris McWhinnie
BBC Monitoring in Amsterdam
Plans
to offer the internet using mains electricity cables could
cause so much interference that new digital radio stations
could be obliterated, a broadcasting conference has been
told. The warning came from Peter Senger,
the chair of the Digital Radio Mondiale (DRM)
at the International Broadcasting Convention in Amsterdam.
DRM is a standard agreed by world broadcasters for a completely
new short wave radio system.
The
new internet power line distribution system has been evaluated
by engineers, including the BBC, and has been found to affect
short wave in particular. Short wave is mainly used to broadcast
internationally and the AM bands have been used since radio
first started in the 1920s. The DRM system uses existing
AM broadcast frequencies to deliver near-FM quality digital
sound. It uses compression to squeeze clear digital sound
into the narrow radio channels that currently carry crackly
analogue signals.
The
DRM technology has the potential to make digital radio available
in places that Digital Audio Broadcasting (DAB) radio or
even FM will probably never reach. As for the hardware required
to hear these stations, there will be a new consumer DRM
radio in the shops by Christmas 2005 and a tiny PC-only DRM
set is already on sale.
DRM
is not being used by many radio stations yet. However a number
of radio stations have seen the potential for new cross-border
radio stations. A Germany-based music station is believed
to be in the planning stages. BBC World Service and its counterparts
abroad already have some regular DRM programmes and are backing
the system.
DRM is being seriously considered in many countries where the FM radio band
is full. China sees
DRM as the answer to pushing digital radio across its vast territory.
The UK is not planning to use
DRM for domestic radio. The UK has pinned its digital hopes instead on DAB,
which offers stations like BBC 1Xtra, 6 Music, Oneword and Core. More digital radios have been sold in the UK than
any other country.
Switching-off
analogue FM and AM may take years and making millions of
much-loved analogue radio sets useless will no doubt be controversial.
If
power line internet transmission is introduced, then international
broadcasting on shortwave may also be consigned to history
due to the interference from data travelling over mains electricity
cables.

LF
band for VK likely by 2008
(Oct 2004)
The International
Amateur Radio Union (IARU) is continuing to push for a new low
frequency amateur band from 135.7-137.8 kHz. The allocation is
on the agenda for the World Radiocommunications Conference in 2007, although it is already
available as a secondary allocation in 25 countries including
all of Europe, Canada,
the United States and New Zealand.
The
Wireless Institute of Australia first requested
an LF band two decades ago when VK radio amateurs, using
Scientific Licences, were engaged in pioneering experimentation
on lower frequency spectrum. The WIA has been unsuccessful
so far in achieving an Australian allocation. The ACA over
the past decade has had 'reasons' for not giving making the
band available as a secondary allocation. One of these was
that it could have regional implications.
Another
barrier was concern about Long Wave broadcasters in the northern
hemisphere, and then doubt over the possible future use of
the spectrum by another radio service. The ACA also wanted
to see that the band had IARU support, which it now certainly
does, and its latest position is that it notes that the matter
will be discussed at the WRC07.
The
end result is that when the LF band is adopted at WRC07,
plus the time it takes to amend the Australian Radio Frequency
Spectrum Plan, VK radio amateurs should get the band by 2008.

ACA blueprint for spectrum management (Sep 2004)
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.

ACA consultation methodology revealed (Sep 2004)
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.

EMR
audits for radio amateurs (Sep 2004)
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.

Broadband over Power Line threat
( July 2004 )
The WIA has recently stated its position on BPL, also known as PLC
or power line communications. WIA National President Michael Owen
VK3KI says while access to broadband capability is important to
Australia, it must not cause interference to legitimate users of
high frequency radio spectrum.
The WIA is encouraged that the ACA is continuing to develop policies
to address the issues arising out of BPL PLC.
The WIA notes that BPL PLC does not provide sufficiently large bandwidth
that is obtainable from fibre optic cabling, and may have less attraction
in the market place in the long term. The WIA says limited trials
which may be conducted from time to time by promoters of BPL PLC
are not a good indication of what can be expected with a large scale
roll out of the technology.
WIA National Director, Phil Wait VK2DKN is now heading a WIA team
that will develop further responses and strategies to counter the
threat to amateur radio of BPL PLC in Australia.
The WIA is not the only group with an interest in HF communications
that is taking a stand against the technology. A number of other
HF users share the WIA's concerns and see it as a threat to their
use of that part of the spectrum.
The BPL PLC trial
in Hobart
The
main energy company in Tasmania, Aurora has completed a small pilot
of BPL PLC that provided Internet access to four homes and two floors
of its office building in Hobart. Electronics firm Mitsubishi supplied
the hardware for the trial that involved seven online users and
ran for about two months.
The system uses multiple discreet carriers approximately every 1.1
kHz between about 1.6 MHz and 30 MHz. The WIA in Tasmania monitored
the trial that was confined in area and did not use overhead mains
power cabling as its transmission medium. Strong multiple carriers
of the system and a click every second were received in the vicinity
of the trial site.
The ACA was also invited to witness the BPL PLC trial. The ACA recognises
BPL is an emerging technology with the potential to play a significant
role in delivery improved broadband access to the general public.
It is monitoring the debate and studies underway in Europe and the
United States.
In the mean time, the ACA is seeking to establish regulatory arrangements
that do not unnecessarily block the use of BPL PLC, but at the same
time provide reasonable measures to adequately protect radiocommunications
reception.

The new HF band
Access to the 60-metre band in a number of countries is proving
to be a boon to amateur radio with the new band providing international
contacts. Some radio amateurs in the United States are reporting
having worked all mainland states and into Britain on as little
as 20 watts on frequencies around 5.4 MHz.
The United States has a number of channels on the band available
to the Amateur Service on a secondary basis - that is that they
do no cause interference to others uses of that spectrum.
A number of other countries have also given restricted access to
their radio amateurs while others are allowing beacon or short-term
test transmissions.
For example, the Marconi Radio Club of Newfoundland VO1MRC recently
conducted experiments using a CW beacon alternately into a low-angle
aerial vertical antenna and a high-angle inverted V. The WIA recognises
the potential of gaining access to spectrum around 5MHz and is now
negotiating with the ACA on this issue.
Aussie schools prepare for chats with space station
At least five Australian school listed to speak via amateur radio
with crew on board the International Space Station. The Amateur
Radio ISS coordinator Tony Hutchison VK5ZAI says the waiting list
for schools is currently around 18 months and a number Australian
schools will get their turn in the next 12 months.
Stealth wallpaper
to combat eavesdropping
A British defence manufacturer has developed a "wallpaper"
to block electronic eavesdropping on wireless LANs used indoors.
The material is made in a similar way to flexible printed circuit
boards using copper strips on a plastic substrate. Its use prevent
outsiders from listening in on in-building wireless LAN traffic,
while letting through other signals such as broadcast radio and
mobile phone calls. Info: http://networks.silicon.com/lans/0,39024663,39121501,00.htm

AMSAT Echo Satellite
Launched Successfully
( July 2004 )
At 0630UTC on the 28th of June the http://www.amsat.org/amsat-new/echo
AMSAT Echo amateur radio satellite was successfully launched from
the Baikonur Cosmodrome in Kazakhstan. Telemetry from the satellite
can be received on 435.150MHz FM. The 10-inch-square microsat, equipped
with a transmitter capable of up to 7 watts output, will allow voice
communications using handheld FM transceivers. However, AMSAT requests
that amateurs do not transmit to Echo until checkout and commissioning
has been completed and the satellite is made available for general
use.
There will be a presentation on Echo at the http://www.uk.amsat.org\t
AMSAT-UK Space Symposium which is being held from the 30th of July
to 1st of August at the University of Surrey, Guildford. This event
is open to all radio amateurs and SWLs and for further information
on it please contact the AMSAT-UK secretary, Jim Heck, G3WGM, on
01 258 453 959 or e-mail: g3wgm@amsat.org
Astronaut and
Cosmonaut Operate Simultaneously from ISS
Staying in space and - for the first time - an astronaut and a cosmonaut
have been on the air simultaneously from both of the ARISS operating
positions on the Space Station. Astronaut Mike Fincke, KE5AIT, operating
as NA1SS, made about 60 contacts on 2 metres during the ARRL Field
Day last weekend, while Expedition 9 Commander Gennady Padalka,
RN3DT, operated on 70-centimetres as RS0ISS. Thanks to the http://www.arrl.org

Actor and radio
amateur Marlon Brando is a Silent Key
One of the best-known names in cinematic as well as amateur radio
circles, actor Marlon Brando, died on the 1st of July at the age
of 80. Known to hams world-wide as KE6PZH and FO5GJ, Brando is listed
on the FCC database as Martin Brandeaux. He was on the air occasionally
through the years with his FO5 callsign from his private island
in French Polynesia. In an interview with Larry King on CNN recorded
in 1994 and shown again this week, Brando confirmed his continued
interest in amateur radio. In response to a caller's question, he
said amateur radio provided him with the opportunity to "just
be himself".

The new WIA gets constitutional approval (May 2004)
The resumed WIA Federal Convention was held via a teleconference
today (16 May) and voted by the required majority to accept the
constitution of the new nationally based Wireless Institute of Australia.
The result
was a "yes" vote from VK1, VK2, VK4, VK5/8, VK6 and VK7.
In line with public undertakings by the WIA Victoria Council, the
VK3 representative Peter Mill VK3APO voted "no".
Those undertakings
included the seeking of legal advice on the proposals in relation
to the new national WIA, and taking a vote of the membership.
The voting
process was difficult, and the required majority came about when
the VK2 Federal Councillor voted apparently contrary to the instructions
of the WIA NSW Council.
The VK2 alternative
federal councillor also participating in the teleconference disputed
the vote, but it was recorded in the affirmative.
The WIA now
has a new President, Michael Owen VK3KI, with the Vice President
being Ernie Hocking VK1LK.
The other directors
are Glenn Dunstan VK4DU, Ewan McLeod VK4ERM, Phil Wait VK2DKN, Edward
Thrift VK2ARA and Trevor Quick VK5ATQ.
The collateral
or implementation agreement that for the new WIA involving all seven
WIA Divisions is still to be negotiated.
WIA Victoria
is proceeding to seek the legal advice on the implementation agreement
to ensure safeguards for its membership, services and assets. A
vote of the membership is also still required before that agreement
can be signed.

ACA review outcome – some decisions
made
(The Presidents
Notes For January 2004.)
The ACA has decided that Australia
will fully participate in the European Conference of Postal and
Telecommunications Administrations (CEPT) licensing system that
gives radio amateurs total reciprocal operating privileges.
While Australia is one of about 60
countries in the CEPT system, it has not signed up for the CEPT
Recommendation T/R 61-01 that enables radio amateurs to operate
in another country without needing to take out a licence in that
country.
The ACA says it’s now talking to the
CEPT about the matter and expects to be able to announce by mid-2004
that VK radio amateurs and foreign CEPT radio amateurs on short
term visits to Australia will have mutual visiting rights privileges.
In other decisions made:
Emergency Communications
The ACA will not make any changes
to current regulatory arrangements in regard to amateur communications
during disasters.
The ACA is still considering whether
to permit the encryption of transmissions for operations and
training with emergency services. And the issue of using abbreviated
callsigns during training and emergency communications is still
undecided.
Prohibition of international communications
under certain conditions
If another country seeks a prohibition on communication with its radio amateurs,
then this will be published in the Commonwealth of Australia Gazette, and communicated
to the amateur radio community.
Third party communications
The ACA will remove the prohibition
on third party communications with overseas countries, unless
another country seeks such a prohibition.
Amateurs must be qualified
to a minimum competence level
The ACA will continue to verify the
operational and technical qualifications of any person wishing
to operate an amateur station.
Operating parameters - purity & stability
of frequency, and maximum power
The ACA will continue to impose limits
on the purity and stability of emitted frequencies, and maximum
power limits on amateur stations in accordance with the ITU's
requirements for transmitting stations.
The ITU requirements will be incorporated
into the ACA's public information documents in early 2004 to
ensure that they are available to amateur licensees.
Amateur-satellite service
The ACA will not make any changes
to current regulatory arrangements in regard to interference
to other stations by stations in the amateur-satellite service.
Amateur Internet linking systems
The ACA will update the Amateur Internet
Linking System (AILS) consumer fact sheet to incorporate changes
to third party communication arrangements.
Morse code requirement
The ACA had earlier announced that
the Morse code proficiency requirement for amateur licensing
would end, and as an interim measure Limited and Novice-Limited
licensees will gain operating privileges below 30MHz from 1 January,
2004.
The big review continues
The ACA is working through the 1,400
submissions it received in response to its review of amateur
service regulations in relation to the remaining proposals, including
the licensing structure and the no-interference policy.
It expects to announce decisions by
mid-2004.

ACA
consultation
(The Presidents Notes For October 2003.)
Melbourne's
ACA consultation has been and gone. Somewhere between 250 and 300
people crammed into a room that would have comfortably seated 200.
9 club members were present.
The ACA's Mr Mark Loney presented
the ACA's preferred position in accordance
with the discussion paper released in August. He then opened the
evening up to questions from the floor taking each point strictly
in the order he had prepared. There was lengthy discussion on the
subject of type of licenses to be issued in future to the amateur
service. Of the three possible Spectrum, Apparatus or Class. Mr
Loney did his best to persuade those present that there was nothing
to fear in a change to a class licensing system. Most were not convinced,
although could accept that a class license system was necessary
for visitors only if Australia is to offer temporary visitors permission
to operate their amateur equipment here within the CEPT concept.
On the issue of whether we have a 2 or 3
tier licensing system on a show of hands it was a close thing, I
think from where I was sitting the vote for 3 was just ahead. The
ACA will wait for all submissions to be collated before making a
decision.
The "No interference policy"
was the last subject on the agenda and with little time left (10pm
finish) there was a push by the ACA to stifle discussion. But thankfully
a person with a roving mike forced a vote on the feelings of those
present on this policy, the result was an almost 100% rejection
of the proposal. It remains to be seen what the ACA make of this.
With Michael Owen VK3KI coming to talk to us on things ITU on Friday
17th we will make time also for a general question time
so that others who attended this function can give their views also.
Keep up to date with coming events
via the Event Queue.
I will be away at Ascot farm sitting
from Thur 23rd Oct until Nov 8th. I
will keep the same sked times and frequencies as Helmut listed in
our September Magazine.
Please find time to send in your
submissions in response to the ACA document, the continuation of
amateur radio as we know it could be at stake. 73's Peter VK3VB

ACA
meeting in Melbourne
8 October, 2003
By Jim Linton
VK3PC
The ACA public meeting on its review
of Amateur Service Regulation held in Melbourne was attended by
160 radio amateurs from throughout Victoria.
During the meeting a show of hands
resulted in the following votes:
- Unanimous opposition to the ACA’s
proposed "no interference" policy for amateur stations.
- Only half a dozen of those in
attendance supported the retention of Morse code as an amateur
licence test requirement. The meeting also gave its general support
for 1 January 2004 being the operative date for an end to code
tests.
- The issue of there being a two-tier
(Entry Level and Unrestricted) or three-tier licence (Entry level,
Novice and Unrestricted) system saw the meeting fairly evenly
divided. The ACA’s Mark Loney said, "...about 50/50 or maybe a
few more for a two-tier structure". Mr Loney said generally there
had been more support for three-tiers at the earlier ACA meetings.
Hobart also had a 50/50 split. .
The ACA’s Mr Loney described the
meeting as the biggest held so far. It began at 7.30pm and concluded
at 10pm.
It stuck to the now well-established
ACA format for these meeting of 30 minutes of a powerpoint presentation
that covers the philosophy of the ACA’s review which is to:
- Seek comment on proposed changes
arising out of the World Radiocommunications Conference held earlier
this year.
- Restructure the licence system
due mainly to the end of the Morse code requirement, plus the
WIA’s proposed Entry Level licence.
- Make amateur regulations and the
administration procedures for certificates of proficiency, callsigns
and licensing, more effective and efficient.
After running through the topics
in the discussion paper, the next phase of the meeting was question
time, with a series of questions being discussed.
The hottest issue of the night was
the ACA’s proposed "no interference" policy for amateur
stations. It was unfortunate that the ACA kept discussion on that
most contentious issue to the very last question in its public meetings
so far.
Soon after the release in late August
of its discussion paper the ACA came out very defensively on the
"no interference" policy in response to email it received.
As it tried to stick to its guns,
the level of opposition to the proposal got stronger. It is interesting
to track to the ACA on this issue as its road-show travels around
the country.
At each city the ACA has slightly
modified or qualified its rationale for the "no interference"
policy, and observers feel it is now backing off or taking a "softer"
approach to the issue.
On the other hand the ACA claims
that radio amateurs are reading much more into the outlined policy
in the discussion paper.
At the Melbourne meeting the ACA
said there were only a few such alleged interference cases a year,
but expressed concern that some are drawn out affairs lasting for
years and involving legal action.
The "intractable" cases
are often caused when both the radio amateur and his complaining
neighbour are uncooperative.
The lack of immunity standards for
domestic radio and television receivers in Australia is also continuing
to cause problems.
Although the ACA has given reassurances
at its public meetings, we must maintain the "rage" against
the totally unacceptable "no interference" proposal as
it is spelt out in the discussion paper.
The radio amateurs at the Melbourne
meeting were not in support of the suggestion that radio amateurs
move from Apparatus Licensing from Class Licensing. They were skeptical
of the implications, and not convinced it would be cheaper.
Mr Loney explained that Class Licences
include CB Radio, LIPDs, marine radio, aviation, and satellite systems.
The ACA website lists 13 Class Licences.
He stated that a Class Licence need
not be limited to type approved equipment. If introduced for the
amateur service, it would include the amateur qualification requirements.
The Class Licence would facilitate
the ACA outsourcing as a package to an outside body, amateur examination,
issuing of certificates of proficiency, maintaining a record of
station locations, and issuing callsigns.
If the Apparatus Licence is kept
for the amateur service, the ACA could still outsource some of the
administrative activities associated with amateur qualifications
and callsigns.
It was made clear on several occasions
by Mr Loney that the ACA desires to achieve changes to amateur service
regulations that are only possible without amendments to the Radiocommunciations
Act.
For example the ACA wants to introduce
a Class Licence for visiting foreign radio amateurs. However similar
provisions for visiting ships and aircraft permitting them to operate
without taking out an Australian licence exist under the Act.
The reluctance to change the Act
is also partly behind the ACA putting on the table that the amateur
service could be covered by a Class Licence. The WIA policy is for
a new Amateur Operators Licence to be established, and recognised
under the Radiocommunications Act.
The amateur fraternity needs to seek
what it believes are the best possible changes, rather than take
what might be second-best or compromise because the ACA is reluctant
to amendment the Act.
Admittedly changes to legislation
can take two years, but that should not be a real issue if we are
to achieve quality long-term changes and improvements for amateur
radio in Australia.
The issue of the proposed lifting
of prohibitions on Third Party Traffic (messages handled by radio
amateurs for non-amateurs) emerged at the Melbourne meeting as one
of topics that had so far not received adequate attention.
Mr Loney was unable to answer all
questions put on this topic. For example, the controls if any there
would be on the handling of private email or private video.
The issue of phone patch, and connection
of an amateur station to the public telephone network were issues
"we have not thought about" he said, and encouraged them
to be raised in submissions.
The amateur fraternity should be
aware that the ACA is continuing on the path it began years ago
of increasingly relying on self-regulation of the amateur service
in Australia.
Probably not fully appreciated is
the fact that the ACA will not look at any new changes for the amateur
service after it has completed this current review and implemented
its changes.
If we get it wrong through the review
process, then we’re stuck with it for five or ten years.

Amateur Radio to be Exempt from
Ban on Driving While Using Mobile Phone
(July 2003)
The Department of Transport
has issued a paper on the results of its consultation on a proposal
for the introduction of an offence of using a hand-held mobile phone
while driving. The consultation document suggested that "two-way
radio microphones" should be included within the proposed ban, which
would effectively have banned mobile amateur radio in the UK. In
its submission to the consultation document, the Radio Society of
Great Britain pointed out that amateur radio had been operated from
motor vehicles since 1955 without any accidents being recorded.
The Department of Transport report on the results of the consultation
states that, "Amateur radio operators, some commercial drivers such
as taxi drivers and hauliers, and some of the emergency services
use [two-way radio] to communicate with a base station. We accept
that such 'press to talk' devices keep conversations short and are
likely to have a lower risk. . . While the details of the extent
of the exemption remain to be determined, the new offence will exempt
the use of such devices."

Switzerland May be First Country to Implement
Code-Free HF Licences
We reported in GB2RS last week
on the major decisions made at the World Radiocommunication Conference
in Geneva. These include the immediate removal of the mandatory international
Morse code requirement for HF-band access, and the welcome news of
an additional 100kHz of spectrum for radio amateurs at 7MHz to be
introduced in 2009. Here in the UK, the Radiocommunications Agency
has already stated that it will bring in code-free HF licences as
soon as it is practical to do so. An announcement will be made on
GB2RS and on the RSGB website when Full and Intermediate Class B amateurs
can start using the HF bands. However, it looks like Switzerland might
be the first country in the world to take advantage of the revised
Radio Regulations. According to the website of the USKA, the Swiss
national amateur radio society, the licensing authority there will
be writing to all Swiss CEPT Class 2 amateurs in the next few days
to give them "provisional authorisation" to start using the HF bands
with immediate effect.
