 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.

 www.gb4imd.org.uk

 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.

 WIA CENTENARY 
  
 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.

 HAMS ACROSS AUSTRALIA AND ONE HAM WHO HAS "WALKED" ACROSS AUSTRALIA IS
 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
 transmissions

 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.

 NEXT SOME ONE WILL COME UP WITH WANTING TO USE cw OR EVEN THE USE OF 500KC
 HIHI

 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.

 USA - BPL

 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."

 NEWS FROM ARNEWSLINE    

 HAM HAPPENINGS:  NPR SAYS HAM RADIO IS GROWING

 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 
 disappear.

 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 
 century.

 Still enjoying ham radio from Scottsdale Arizona, I'm Norm Seeley, KI7UP, 
 reporting for the Amateur Radio Newsline.

 WEIRD AND WONDERFUL
 
 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
 Clements.
 
 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. 
 
 (SouthGate)

 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!

 PROPAGATION:  SOLAR WINDSTORM HITS EARTH

 In propagation news, what's described as a sharp gust of solar wind hit 
 Earth's magnetosphere on Monday, April 5th, at approximately 0800 UTC.  It 
 also sparked the strongest geomagnetic storm of the year.
 
 According to Spaceweather dot com, the event registered 7 on the 0-to-9 K 
 index scale of magnetic disturbances. Although the storm was subsiding by 
 Wednesday morning, April 7th,  it was not over and high-latitude sky 
 watchers were told to remain alert for the possibility of aurora 
 propagation.

 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.

 REWIND - A LOOK BACK IN HISTORY   
      
 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
 electronics. 

 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.

 Rewind a look back at our history through the serialised written history
 by WIA Centenary Committee member Peter Wolfenden VK3RV with assistance of
 others, that is being published in the WIA journal Amateur Radio magazine.


 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
 reality. 

 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!
