WIANEWS FOR WEEK COMMENCING APR 18 2010. - International Marconi Day. - Clubs
supporting the Centenary. - HAMS ACROSS AUSTRALIA. - Save Analogue Radio
campaign. - Low-energy light bulbs that take control of your TV. - Brisbane


International Marconi Day

Next Saturday 24 April, Hornsby and District AR Club will be one of the
select few world clubs officially celebrating a VERY significant event!

Over the sea to Ireland and the Howth Martello Radio Group and the
North Dublin Radio Club will join in.

All these stations plus others will be celebrating International Marconi Day.

The IMD award station from the Martello Tower in Howth will use the
call-sign EI0MAR. The Martello tower houses the vintage radio museum.

The Cornish Radio Amateur Club organises this annual event and details of the
awards and a list of award stations is available on their web site.

GB4MBP and GB0MD will be on the air on 22nd April as part of International
Marconi Day activities. The first will be on the air from the Lizard in
Cornwall and the second station from Kent.

But to VK, thanks to Hornsby's Julian Shortland Paul Latter VK2CPL joins WIA
National news.

"Next Saturday, 24th April is International Marconi Day. Members of the
Hornsby & Districts Amateur Radio Club will be operating VK2IMD on a
range of HF bands. Operation commences at 10:00 am eastern time, this
being the beginning of the UTC day, and continues for 24 hours. HADARC
takes part due to their proximity to the Fisk House in Wahroonga where
the first direct radio message from Britain was received. It was sent by
Marconi from his station near Caernarfon [then spelled using the
anglicised "Carnarvon"] in north-west Wales, on behalf of Australian
Prime Minister Billy Hughes. Further information is available on the
GB4IMD website.

For VK1WIA News this is Paul Latter VK2CPL.

Clubs supporting the Centenary

The WIA Centenary Committee has inducted three more events which are now
officially WIA Supported Centenary Activities.

The Gippsland Gate Radio & Electronics Club south-east of Melbourne in
association with the Koo-Wee-Rup Historical Society, will from the 16-18 June
re-enact the first wireless press messages between the United Kingdom and
Australia in 1921.

GGREC President Chris Chapman VK3QB tells us this event will also recognise
the contribution that the local community made to these early days of
pioneering and advancement of our country delivered by wireless telegraphy.

Another event is the 35th annual Oxley Region Amateur Radio Club Field Day
at Port Macquarie New South Wales 12-13 June.

Club President Henry Lundell VK2ZHE has also advised that this year it?s
the club?s 40th anniversary year.

The third event is the RadioActive Amateur Radio Award for Scouts in July.

Scouts Australia JOTA-JOTI Coordinator Bob Bristow VK6POP said it's
recognised that the WIA played a key enabling role to deliver the new era of
amateur radio including the Foundation Licence ? which has resulted in a
substantial increase in the number of amateur radio scouts.

In appreciation the scouts will actively support the WIA Centenary with the
RadioActive Amateur Radio Award.

The aim is to make contact with other scouts and also to seek out contacts
with the special centenary callsign VK100WIA.

Jeff Johnson VK4XJJ who walked across Australia from south to north,
Gulf to Gulf

VK4BAT Trevor Tage has more on Jeff Johnson.

"He had a daily sked with Roger VK4BNQ on 40m and made several sat-phone
radio interviews with ABC radio and our own WIA news producer Graham VK4BB.

Well Jeff has another little walk planned but this time it is from east to
west! right across Australia!!

The Royal Flying Doctor Service has approached Jeff to complete this huge
fund-raising walk on their behalf. They will be providing support along
the way and the Gympie Communications & Electronics Group will be Jeff's
official East Coast Amateur Radio contact station.

The walk is being planned to commence early April 2011. With anticipated
radio and TV coverage, 'Jeff's Walk' will once again raise money and
awareness for a good cause and help to promote and demonstrate Amateur Radio.

Port Stephens Amateur Radio Club members will be operating a portable station
under the club call VK2AOJ at Fort Scratchley, Newcastle Anzac Day 25 April,
between 12.30pm and 3.30pm local VK2 Time.

Fort Scratchley has a long and rich history. It was reopened to the public in
2008 after being restored to its former glory, and now attracts thousands of
visitors each year. A team of dedicated volunteers maintain the site's many
exhibits and provide guided tours of the fort.

The fort has guarded the entrance to Newcastle Harbour for nearly 200 years
and is famous for becoming the only coastal fortification to fire on an enemy
naval vessel.

On the night of 7-8 June 1942 the Battery's 6-inch guns fired two salvos at a
Japanese submarine that bombarded Newcastle with about two dozen shells.

The Port Stephens Amateur Radio Club group will be taking the opportunity to
promote amateur radio and the fort to the visiting public.

THEY have produced a QSL card for the occasion and this will be exchanged
with all contacts, well probably more than 1 card so they don't keep
exchanging the same card hihi.

Save Analogue Radio campaign

A UK National Campaign to maintain traditional analogue broadcast radio for
everyday listening and for use in times of national emergencies is trying to
spring up.

The pressure is on to replace traditional analogue radio broadcasting with
Digital Audio Broadcasting (DAB) radio.
Indeed, the UK Government has provisionally set 2015 as the date when the
world wide standard frequency modulation (f.m.) services are to disappear
from 87.5 to 108MHz (v.h.f. f.m. band), to be replaced with DAB radio

Eventually, the analogue services on long waves (198kHz) and medium waves
(500kHz to 1.6MHz) will also be replaced by digital transmissions.

But one would wonder at this backward step to save thin sounding FM and at
worse crackly 4khz AM.


But if you DO want to know more you can contact Rob G3XFD, oh and Rob is
actually DOCTOR Rob B Mannion the Editor of Practical Wireless magazine.


The 78th AGM of Irish Radio Transmitters Society will be hosted by the Dundalk

Once touted as "the most successful BPL deployment in the nation,"
the City of Manassas has decided to get out of the BPL business, once
and for all. At a Special Meeting on Monday, April 5, the Manassas City
Council -- acting on a recommendation from the Manassas Utilities
Commission -- unanimously voted to discontinue Broadband over Powerline
Internet service as of July 1, 2010 to the approximately 520 residents
and businesses who subscribe to the service; these customers were told that
they have three months to find a new Internet service provider.

According to Manassas City Clerk Andrea Madden, there was no discussion on
the resolution to discontinue service and the motion was passed
"without incident."





National Public Radio says that ham radio is alive and well, and its even
produced a segment of its All Things Considered program to prove
it. Amateur Radio Newsline's Norm Seeley, KI7UP, has more:

Ham radio is far from the dying hobby that the nay sayers claim it to
be. One that only a few years ago was being touted by techno blogs
alongside 35 mm film and home videotape as technologies slated to quickly

Well, National Public Radio says that the bloggers were wrong
because there are now nearly 700,000 U-S citizens who have ham radio
licenses. NPR says that number is up by some 60 percent since 1981. And
Says NPR, that number is growing.

The NPR story quotes Allen Weiner. He is an analyst at the technology
research firm Gartner and Associates. Weiner says that while ham radio
will never have the sex appeal of the iPhone, it does have a certain level
of what he terms as nerd appeal.

Weiner also explains growth in our specialized communications interest in
this way. He says that if it creates its own experience, that's really
what's key here. Conversely, if it just emulates an experience that you
can get online, it's not going to grow.

The report concludes by noting that even the most die-hard hams admit that
amateur radio will never be a mainstream hobby. But says National Public
Radio, people are still discovering the joy of communicating with the
technology of amateur radio. A technology that has existed for nearly a

Low-energy light bulbs that take control of your TV

Some feared it must have been a problem with their remote. Others suspected
ghostly goings-on.

But when TV viewers complained their sets were changing channel by
themselves, few could have guessed the real culprit - their light bulbs.

Low-energy bulbs can make your television turn over the station at random,
according to customers.

Among the first to spot the problem were UK cable customers Alistair and Emma

They rang their supplier, Virgin Media, and were told the problem could be
because of the Philips low-energy light bulb fitted nearby.

But while changing it helped, the couple say the channel still flips from
time to time even though the nearest low- energy bulb is now in another room.

Experts say infra-red light from modern fluorescent bulbs can be 'mistaken'
by electrical equipment for commands from its remote.

They warn that while moving or changing the offending device usually solves
the problem, the proliferation of gadgets in homes increases the likelihood
of such interference.

Traditional bulbs produce infra-red too, but because they don't 'flicker'
like some fluorescent bulbs there is no danger of interference with
electrical equipment.


This weird and wonderful occurence is akin to a problem my next door
neighbour had soon after he had a pace maker installed. Every time I changed
TV stations he would do cartwheels in his lounge!

The RSGB say "German cable operators have been encouraged to improve systems."

The Cologne Administrative Court has rejected an action brought by a
German cable company against the auction of 800MHz for wireless
networks, saying that if the cable operator was afraid of
interference they could take action to improve their cable system.

The Deutscher Amateur Radio Club views the ruling positively since it
will encourage cable operators to upgrade leaky cable systems. As
well as stopping the pickup of any 800MHz transmissions it should
also reduce the interference that leaky cable systems cause to radio amateurs.

Sixty-two Years of The Transistor

"Where a calculator on the ENIAC is equipped with 18,000 vacuum tubes and
weighs 30 tons, computers in the future may have 1,000 vacuum tubes and
perhaps weigh 1.5 tons."

So said Popular Mechanics, March 1949.

But we all know don't we that just 2 years prior to that article in 1947,
John Bardeen and Walter Brattain at AT&T's Bell Labs in the United States
noted that the output power was larger than the input power when electrical
contacts were applied to a crystal of germanium.

Another worker at the AT&T's Bell Labs, William Shockley, saw the "potential" in this
and developed the transistor.

In an item in this weeks "on line" from the NZART, they remind us that the
term 'transistor', was coined by John R. Pierce from the words 'transfer'
and 'resistance'.

The first silicon transistor was produced by Texas Instruments in 1954. This
was the work of Gordon Teal, an expert in growing crystals of high purity,
who had previously worked at Bell Labs. The first MOS transistor actually
built was by Kahng and Atalla also at Bell Labs, but Fast forward to 1960.

The transistor is the key active component in practically all modern

Although several companies each produce over a billion individually-packaged
(known as discrete) transistors every year, the vast majority of transistors
now produced are in integrated circuits (IC). Complete electronic circuits
are made by combining integrated circuits with diodes, resistors, capacitors
and other electronic components.

In 2010, a microprocessor, the heart of your home computer, could have up to
820 million transistors with a speed of over 3 GHz.

Do you remember the XT or '286' computer? That computer, from 1982, had a
microprocessor that had 134 000 transistors in it and a speed of 6 MHz!

About 60 million transistors were built in 2002 for each man, woman, and
child on Earth.

The transistor's low cost, flexibility, and reliability have made it a
universal device. Transistorised mechatronic circuits have replaced
electromechanical devices in controlling appliances and machinery. It is
often easier and cheaper to use a standard microcontroller (a microprocessor
with input and output circuits), and write a computer program to carry out a
control function than to design an equivalent mechanical device.

Interference threatens experimenters

By the end of 1921 there were sufficient stations using regenerative
receivers, that interference was being experienced by all users of the
spectrum in some parts of the country.

An improperly adjusted receiver actually transmitted a signal. The earlier
fears of the South Australian Division that this would occur had become a

Newspaper reports in July 1922 proclaimed that experimenter?s licences were
in jeopardy.

Again the co-operation of all state WIA bodies was obtained to protect the
rights of experimenters. At this time a reduction in high licence fees was
also on the agenda.

The delay in making transmitting licences readily available generated a deal
of impatience from experimenters and those wishing to open up the commercial
possibilities of wireless.

Basically the only stations that could be received at the time were the
coastal stations, ships at sea, a few land stations including those operated
by the WIA, and the occasional official telephony experiment.

A number of experimenters keyed their oscillating valve receiver operating
it as a low powered transmitter - all highly illegal!
