Text edition:
THIS WEEK:-
Joining u this week the usual bunch of suspects, VK2LAW, VK4FUQ VK3GTV and
Editor of the WIA Journal AR Roger Harrison VK2ZRH.
BUT WAIT - THERE'S MUCH MUCH MORE IN THIS EDITION OF NEWS FROM THE
WIRELESS INSTITUTE OF AUSTRALIA.
I'M EDITOR GRAHAM VK4BB
Now before we get into this weeks news, a look at the past, with VK3ABP
This is Peter Rice, VK3ABP.
Often significant DX amateur radio transmissions occur due to ephemeral
atmospheric conditions, but it's not often significance is due to them
being broadcast from an ephemeral salt lake!
Yet, on the 14th May, 2025, there was a 50th anniversary of just that, when
my dad Bill Rice, VK3ABP, now silent key, broadcast maritime mobile from a
Red Baron catamaran, under sail on Kati Thanda 'Lake Eyre North' in 1975,
on Arabana Country in Northern South Australia.
It's sacred Country. And, with permission granted by Arabana elders in
2008, where my silent key dad's ashes remain.
Lake Eyre is currently receiving water from recent major flooding in
northern Australia, but still may not fill to match the volume of water
which was there in 1975. We can hope, despite restrictions on sailing, and
even going near the lake, now.
Let Bill tell you more, from a QSO with Snow Campbell, VK3MR (also now
silent key) in Melbourne, recorded on 14th May 1975 while sailing on Lake
Eyre. You can hear water splashing against the hulls!
VK3ABP: "Yeah roger, Snow - VK3 Mike Roger, in Melbourne; VK3 Alpha Bravo
Papa, VK3 Able Baker Peter, maritime mobile /5 on Lake Eyre returning. All
ok, Snow; your signals readability 5 strength 9 - we are under way, under
sail, in Madigan Gulf, in the south east corner of Lake Eyre at the present
time; we have at least 10 feet of water underneath us, probably more than
10 feet of water underneath us, and making about five knots very very
nicely. Ah - running about 50 watts peak, possibly not even that, using
the mast off the boat as the antenna through a trans-match, and ah, it's
about a twenty foot mast, and ah, using the ah, lake water as a ground
through a small ah, ground electrode, ah under one of the hulls. So that's
the story Snow. Name here is Bill, Bravo India Lima Lima, Bill is the
name, and ah, wonder how you copy there in Melbourne. VK3MR, VK3ABP
maritime mobile /5 Lake Eyre."
Video of that excerpt can be seen in a short film called, 'On Eyre', E Y R
E, made at the time by Bill and Tim Robinson, VK3YBP, which just over a
fortnight ago was accepted into the Australian National Film and Sound
Archive.
Tim Robinson has recently indicated to me that the film may also be
possibly uploaded to the Digital Library of Amateur Radio Communications.
It's sure not often that telephony of amateur radio communications is heard
50 years since first broadcast, let alone any from a boat once sailing on
what is still mostly even now, normally a dry salt-lake claypan.
For WIA National News, I am Peter Rice, VK3ABP.

Hello all, including those MAD members out on lookouts and ridges enjoying a microwave activity day.
This is Editor-in-Chief of Amateur Radio magazine, Roger Harrison VK2ZRH coming to you from Southport in Queensland, down in the hollow beside Loders Creek.
Make yourself comfortable, I have some news. Not mad news, or sad news, or even bad news. Here it is:
Issue Number 3 of Amateur Radio magazine rolled off the press at Bairnsdale last Wednesday, on time and as budgeted.
Next week, the magazine will leap into letterboxes, Post Office Boxes, and numerous newsagents across the country, plus a few landing overseas.
The theme for this issue is one that we have not published previously called Simplicities and Complexities.
So, its a collection of articles on simple subjects along with some on complex matters generally unrelated.
But, wait! Isnt that something you do every issue, I can hear you asking?
Well, yes. But, this time, only more so. Our issue themes mean that we collect or curate a series of articles themed around a related topic Antennas and Propagation, D I Y, Hacks and Hints, Portable Pursuits, etc.
Which is what makes this issue different. Its the opposite of a curated theme.
So, what have we got?
I recall a new member asking me at a club meeting, just what are auroras? So, we have a feature article on the subject, titled Auroras a tour for tyros. Naturally, the cover features a dramatic auroral photo.
With the solar cycle peak now at hand, people across the southern regions in the southern states, and particularly in Tasmania, have often been treated to aurora light shows.
They affect radio propagation on HF, while some amateurs exploit them for auroral scatter VHF contacts.
Written for a general audience, our article answers the questions: What are they, and why do they come in different shapes and colours?
That ones for you, Colin.
Elsewhere, we have a charming little build it yourself project a simple shortwave receiver, by Dale Hughs VK1DSH.
Its based on a design originally published in 1967, but not actually a copy. And, yes, it uses a couple of valves! Hamfest sale-and-swap sections are always great sources for components to suit this project, not to mention the back shed or the attic.
Moving-on to complexities, we have another article from George Galanis VK3EIP. Readers will remember him from his articles last year titled, On Lobes and Dishes.
This issue, his article is on What happens when you hit push-to-talk. This is Part 1 of a two-part series on just how moving electrons in a piece of wire create an electromagnetic wave.
Indubitably, it has equations! But, as George points out, its high school level mathematics.
James Clerk Maxwell gets a mention, but theres no sign of his curly equations.
George says that, even if you dont have the high school maths, you may find it useful to skip over the bits you dont understand and hopefully still gain some insights.
For those keen on the complexities of chasing DX and hunting a contact with the latest DXCC country entity, this issue we have published the 2024 DX Leaderboard all grades.
Well, the top 30 stations out of 107 entries. See whos who on the ladder and what rig they used. Who is the high-scoring homebrewer in there?
Rounding out the theme, for the do-it-yourself readers handy with hardware tools, we have a simple 2-band antenna for 10 and 12 metres, put together from re-purposed TV antenna parts and some hardware store aluminium tubing. It also involves winding a toroid choke for the feedpoint.
Under the banner of Your WIA Working For You, this issue we give readers some insights on the Institutes formal response to the recent omnibus consultation paper from the Australian Communications and Media Authority concerning its Five-year Spectrum Outlook and its 2025-26 work program also known as the FYSO.
The WIA Spectrum Strategy Committee developed a response, which it titled Strengthening the Future of Amateur Radio in Australia.
The submission sets out six key areas that the WIA seeks to be addressed over the coming year, including a number of outstanding Class Licence issues, call signs, planning for high power, exams, repeaters and beacons, and critical spectrum issues concerning the 5 MHz allocation and preserving the bands at 51-to-52 MHz and 2300-2302 MHz.
Thats it for now, listeners. Hopefully, Ill have more for you next week.
Dont forget, theres always much-much, much more in every edition of Amateur Radio magazine.
More guts. Less gab. Serving Australian amateur radio operators since 1933. Proudly produced and printed in Australia.

Dayton Hamvention 2025 returned last weekend to the Greene County Fair and Expo
Centre where tens of thousands of amateur radio enthusiasts gathered.
This year's theme was radio independence, celebrating the freedom and resilience
that have always defined amateur radio. Hamvention goes back to the early 50s.
From the earliest spark transmissions to today's global digital modes ham radio has
pushed boundaries in innovation, service, and community. "If you don't know
anything about amateur radio, there's more to amateur radio than what most people
realize," said Michael Kalter, Hamvention spokesperson. "We respect our frequencies
that were allotted. We want to keep those frequencies. We want to continue to use
them, as do other amateur radio operators throughout the world, and there's a whole
lot of new activities that are going on with amateur radio."
Some travelled from around the world.
16 different countries were represented there, with more than 600 volunteers
helping to make the event run smoothly. They call it a labour of love in enjoying
the show, learning something new, and making new friends.

Amateur Radio Exam in Bangladesh sees an unprecedented turnout, with more than
900 participants taking part in the examination organized by the Bangladesh
Telecommunication Regulatory Commission (BTRC). This historic event took place in
Dhaka and witnessed amateur radio enthusiasts from diverse regions across
Bangladesh coming together with a shared passion for radio communication.
The Amateur Radio Society of Bangladesh said on its website that "this remarkable
figure represents the highest number of participants ever recorded for an amateur
radio exam in Bangladesh's history."
Weeks of preparation had gone into preparing candidates for the exam by offering
online seminars as well as in-person training and workshops. There was also a field
day as well as classes in basic electronics and antenna-building. The amateur
radio society said there was great support from the Bangladesh Vespa Community,
a community-service group of motorised-scooter enthusiasts - many of whom also took
the exam, which was organised by the Bangladesh Telecommunication Regulatory
Commission.
The Amateur Radio Society Bangladesh (ARSB) has played an instrumental role in
promoting amateur radio activities, contributing significantly to this surge in
interest. ARSB has been instrumental in fostering the amateur radio community by
hosting a variety of events since 2018 & ARSB is a govt. registered organization
in Bangladesh.
IARU Monitoring System Region 1 Newsletter
The April edition of the IARU Monitoring System Region 1 newsletter is available
for download. It starts with information regarding a proposal submitted to the
IARU Administrative Council to revise the Terms of Reference of the IARU Monitoring
System. Contained within the text is a proposal to rename the working group to the
IARU Intruder Watch Service and expand the group's scope to include frequencies
allocated to amateur satellites.
You can learn more about the proposal and see what intruder signals were reported
for April in the free newsletter.

A long-time pirate radio operator in South Florida has agreed to stop broadcasting
and pay an $11,000 penalty to the U.S. Treasury through a 20-year consent decree.
Wilfrid Salomon was found to be operating Radio Ideal, an unlicensed FM station
targeting the Haitian community. Miami field office agents visited locations from
which Salomon broadcast in 2017, 2018 and 2023.
Salomon agreed to a penalty of $11,000 paid in $500 monthly instalments.
He will face an additional penalty of approximately $347,000 if he violates the
decree during the 20-year consent period by committing another pirate radio offense
or missing a payment.
GOIG - GOING - SOLD!
The Society of Broadcast Engineers auction of the remaining elements that were
part of the Alford Antenna atop the Empire State Building raised $7,549 for its
engineer scholarship fund.
Bud Williamson, the chair of the New York City-based SBE Chapter 15, said that the
auction of the antenna bays was a success. The auction was conducted in the second
half of April. All proceeds will go to the SBE Ennes Educational Foundation Trust.
The winning bidders are in the process of either picking up or arranging shipment
of their prizes now and all bays have been paid for, Williamson said.
Each element weighs approximately 100 lbs.

VHF UHF Field Days
Contest Manager Roger Harrison VK2ZRH.
Winter 2025
Saturday 21 June through Sunday 22 June
The Field Days provide VHF-UHF operators with the opportunity to "head for
the hills" and see how far distant and how many stations they can work.
The Field Days have separate sections for single and multiple operator
stations. The duration of the Field Day is 24 hours, but there are also
8-hour sections for operators who may not be able to camp overnight.
Notably, most club stations prefer to operate for the full 24 hours.
The Field Days also generate plenty of activity from home stations,
so there is also a separate Home Station section.
All contacts must be simplex: contacts through repeaters or satellites are
not allowed. There is plenty of FM activity, but one feature of the Field
Days is a high level of SSB activity.
It is possible to do very well with only modest antennas IF you pick a good
hilltop. Another option, if your station is easily transportable, is to
operate from more than one location during the contest period.
The overriding aim is to get away for the weekend and have fun!
But next after that, the aims are:
to encourage more activity on VHF, UHF, and microwave bands;
to encourage people to work greater distances than usual by operating
portable, and to provide opportunities for people to activate or work
into new grid squares.

Ken Yamamoto, JA1CJP Secretary, IARU Region 3 in an email passed to us by
WIA Secretary Peter Clee reminds us here at the WIA that in this contest
multipliers are the total number of ITU zones plus IARU member society HQ
stations worked on each band (not mode). Thus, Society's HQ stations
(WIA) participation is very important for the multipliers.

WW SPECIAL INTEREST GROUPS --- ASTRONOMY (and Wireless Weather)
Think of them as the dynamic duo of the universe:
No, they're not caped crusaders but a red dwarf star and a white dwarf, a dead
star. Together, they have been sending a steady radio pulse every two hours
for at least 10 years.
Scientists have heard their transmission but until recently no one knew the source
of the sounds, which appeared to emanate from the direction of the Big Dipper.
Recently, the signals were found to come from a binary system - two stars - that
send the pulse by repeated contact between their magnetic fields. Researchers
cracked the mystery with the help of a low-frequency array radio telescope. The
discovery debunks the long-held belief that only highly magnetized neutron stars
known as magnetars, can emit such pulses.
This challenge to the old way of thinking opens up the chance to explore other
mysteries and binary systems.

WW SPECIAL INTEREST GROUPS - BALLOONS
It was a clear day, members of the St. Pius X High School Amateur Radio Club
watched their hard work float away.
They had launched a pico balloon from the schools football field, the balloon
with a transmitter dangling was watched by around 30 students.
The balloon, made of Mylar and filled with hydrogen, was released into the sky with
the expectation that students would track it on a website as it circled the earth
at an altitude of about 40,000 feet. Pico balloons can circle the earth in about
four to five days, and may remain in the air for more than a month, said Travis
Few, a Midwest High-Altitude Balloon Team flight lead, who has helped the St. Pius
club with the balloon project since late January.

If you were lucky enough to work HV 5 PUL transmitting from Rome recently, you were
part of this small university-based station's celebration that a new pope had been
chosen.
Two days after the conclave of cardinals had elected Pope Leo XIV, amateur radio
station HV5PUL - the Pontifical Lateran University - was on the air in the
Vatican City State in the heart of Rome, celebrating.
The station's administrator, Luca Della Giovampaola, IWDJB, reported that traffic
was lively on 20 metres SSB and 17 metres FT8. He said that the simple 100-watt
station logged an estimated 400 contacts in four hours. Propagation was challenging
and so, with the exception of one Japanese station , all the contacts were within
Europe.
It's not often a new pope is chosen nor that HV5PUL is put on the air, the callsign
is active mainly on Saturdays in connection with special occasions, such as the
opening day of the university's academic year -- and of course, the selection of a
new Pope.

Amazon's new broadband internet constellation project has moved ahead with its
first lift-off.
Yes the broadband internet constellation known as Project Kuiper is on its way at
last, following the launch on Monday, April 28th of its first 27 satellites from
Cape Canaveral Space Force Station in Florida.
Amazon envisions its long-anticipated $10-billion project as a direct challenge to
the massive SpaceX Starlink network, which dominates the market. Ultimately
Project Kuiper will send 3,236 satellites into low-Earth orbit, making its global
broadband service accessible to rural and underserved regions.
A mandate by the US Federal Communications Commission requires Amazon to deploy
1,618 - or half - of its satellites by the middle of 2026. Analysts speculate that
the company may seek an extension on that date as a result of the delays.

WW SPECIAL INTEREST GROUPS - INTERNET - THE HAMS DOMAIN.
We occasionally have been taken to task when reminding listeners and viewers to
visit wia.org.au for the text edition.
YOU SHOULD BE SAYING WWW.WIA.ORG.AU some say.
Wrong we say, and in any case, most browsers have taken a stance against the
significance of www. Chrome, Safari, Firefox all hide the prefix even
when you are technically visiting a website that does still use the www. subdomain
(like http://www.wia.org.au). You can try it yourself in Firefox head over to a
www. site and watch as the prefix disappears or part fades to grey from the
taskbar.
The www prefix stands as a reminder that the internet is a living, evolving
thing.
Over time, technical necessities become conventions,
conventions become habits,
habits eventually fade away when they no longer serve a purpose.
Yet we still see those three letters pop up on the Web now and then, a digital
vestigial organ from the early days of the web. The next time you mindlessly type
a URL without those three Ws, spare a thought for this small piece of internet
history that shaped how we access information for decades.
Largely gone, but not yet quite forgotten.

WW SPECIAL INTEREST GROUPS ---- MARITIME.
Michael VK2HFN, recently went maritime mobile on the Carnival Splendour, along the
East Coast of VK2 and VK4.
With permission, VK2HFN picked a spot near the aft of the ship, well away from the
ships antennas and navigational equipment. He was able to make many contacts along
the coast through several repeaters. The longest distance was nearly 180km through
VK2RCH, Coffs Harbour.
This was done on his VX6, transmitting with only 1 watt.
Once operating, Michael was never bothered while operating his radio and enjoying
this great hobby. If anyone is thinking on going on a cruise, the Carnival
Splendour is Ham Radio Friendly, according to Michael.

50 years since the end of the Vietnam War and a great video has surfaced on the
Military HF Radio YouTube channel.
youtube.com/@militaryhfradio244
This talk has a particular focus on the Vietnam conflict, the use of HF at that
time as well as training required and of course the challenges of military
bureaucracy.
Wednesday was lecture night at the Manly-Warringah Radio Society.
The topic, "Spy Radio, the Special Operations Executive, and Deception, presented
by Colin Christie VK2JCC. It delved into the vital role of covert communications
during World War II, focusing on the use of spy radios by the French Resistance.
These radios were essential for transmitting critical information to Allied forces,
often under life-threatening conditions.
SOE, the Special Operations Executive, a secret British organization, played a
crucial role in coordinating these efforts, training agents in espionage, sabotage,
and the use of encrypted communication.
The presentation also explored the deceptive tactics employed to mislead the enemy,
including misinformation campaigns and fake radio transmissions, all which helped
confuse and disorient German forces.

Most enthusiasts would be well aware of the annual Military Radio Nets that
take place on Saturday at Hamvention in the USA.
3885 AM WW2 Low power and backpack net at 1200 hours local
51.0 FM Cold War backpack and handheld net at 1400 hours local.
The 3885 WW2 Net featured everything from BC-611 to SCR-284, GRC-9 etc.
The 51.0 Cold War Net had radios like the PRC-6, PRC-10, RT-70, PRC-25 and 77 with
a good representation of older sets from the BC-1000 to newer SINGARS sets. They
had at Hamvention a good showing of German, Russian and captured Iraqi radios.
The Czech RF_10 was another popular radio.
