PROJECT PURSUES MYSTERIES OF SPORADIC E-SKIP
STEPHEN/ANCHOR: We begin this week with a new project by a ham radio
operator who is trying to unlock the mysteries of sporadic E-skip. Andy
Morrison K9AWM tells us what the project is looking at - and how you
can look at it too.
ANDY: Loyd Van Horn, W4LVH, is a fan of mysteries and there are perhaps
few ham radio mysteries greater than that of Sporadic E-skip which makes
its appearance on VHF in the Northern Hemisphere every year at about
this time.
Loyd is the force behind DX Central, a resource for DXers that does,
among many things, data analysis. This month he unveiled SEDAP, an acronym
for his Sporadic Es Data Analysis Project. It can be found at fmdxdata.com
and is free to use by hams, educators and anyone with a hobbyist's interest
in this special season that turns propagation magical in the eyes of
many.
He writes on the website SWLing Post that he compiled more than 95,000
FM broadcast logs from North America to get the data relevant for the
project, which goes beyond simple spreadsheets by adding interactive
visualizations.
He writes: [quote] "SEDAP allows us to physically watch ionospheric clouds
spawn, compress and track across the continent in real-time. We can finally
see what a typical season looks like on a macroscopic level." [endquote]
He told the Radio World website that he also plans to include amateur
radio data from 6 metres. He said that will permit analysis of days that
had no propagation alongside days with active openings - days on which
the maximum usable frequency did not reach the FM broadcast band.
This is Andy Morrison K9AWM.

UK HAMS PLAN TRIBUTE TO BBC TRANSMITTERS MARKED FOR SHUTDOWN
STEPHEN/ANCHOR: There's always been a strong affinity between amateur
radio and our colleagues in broadcasting. So whenever there's a change,
or an end to things, hams take notice - as they will be doing in the
UK this year where the BBC is shutting down its long-wave radio service
on June 27th. Jeremy Boot G4NJH tells us what's next.
JEREMY: Commissioned in 1934, the BBC's Droitwich long-wave transmitter
went on the air delivering programming at what was to become a major
facility. It played an important role in occupied Europe during wartime.
Over the decades that followed, its broadcast programmes became the background
to so many lives throughout the UK.
Responding to the BBC's announcement of this year's shutdown of the Droitwich
Transmitter, as well as Long Wave transmitters at Burghead and Westerglen
in Scotland, amateur radio operators have plans to mark the end of the
era. The BBC Amateur Radio Group and the Radio Society of Great Britain
are planning an on-air event and are looking for hams around the UK to
participate.
Meanwhile, hams are being asked to let organizers know they are interested
by emailing contestclub at rsgb dot org (ContestClub@rsgbcc.org)
This is Jeremy Boot G4NJH.

AUSTRALIAN RADIOCOMMUNICATION LICENSES GET NEW WEBSITE
STEPHEN/ANCHOR: In Australia, the nation's regulator has introduced a
new website for radiocommunication licenses, as we hear from John Williams
VK4JJW.
JOHN: A new website for broadcast and other radiocommunication licences
has gone live in Australia, with changes designed to simplify searches
by offering a variety of filters along with customisable options for
the export of data.
This replaces the older website, which the Australian Communications
and Media Authority will keep online until the 10th of June during the
transition period. The new site does not contain data about any class
licences, which include citizens band and amateur radio. Australia introduced
the amateur class licence in February of 2024 in a sweeping change that
replaced individual amateur radio licences.
The ACMA has also designed the new site a resource for broadcast licence
applicants, who may see what frequencies are available and other relevant
information.
This is John Williams VK4JJW.

NEW ZEALAND CYCLONE REVS UP RECRUITMENT DRIVE
STEPHEN/ANCHOR: A recent cyclone that hit New Zealand has left its mark
- not just on the country's East Coast but among emergency communicators
there, who are stepping up their recruitment efforts as a result. Jim
Meachen ZL2BHF has those details.
JIM: Volunteers from Amateur Radio Emergency Communications Tauranga
answered the call in April when the severe storm known as Cyclone Vaianu
approached the coast. TairÄüwhiti Emergency Management in Gisborne was
asking that the hams keep communication lines open throughout that tense
weekend. AREC members were able to staff the emergency centre radios
which are connected to remote community civil defence teams.
The volunteers were reminded that this is the very purpose for which
AREC was established in 1932 and the reason it has since evolved into
something that Civil Defence, Search and Rescue and police can rely on.
Last month, three of the Tauranga volunteers went to Gisborne and worked
in shifts around the clock to ensure welfare checks were made and community
contact was maintained, especially in the most remote areas. One community
ended up having a power failure - and their backup power did not function
either - and so the AREC volunteers got that addressed.
AREC also created a nationwide safety net on the HF bands.
The team is now hoping to grow even stronger by adding trained volunteers
and put out a call through local media to ask that interested people
contact them.
Group leader Joanne Watson ZL1JDR told the SunLive website: [quote] "You
never know when your skills might be the link that keeps someone connected."

SILENT KEY: ROSS MERLIN, WA2WDT. EMERGENCY COMMUNICATION PROFESSIONAL
STEPHEN/ANCHOR: An important and influential figure in disaster communications
in the United Stated has become a Silent Key. We learn about his contributions
from Travis Lisk N3ILS.
TRAVIS: If you are involved in emergency communications or security,
it is likely you're familiar with the name of Ross Merlin, WA2WDT.
Ross became a Silent Key on the 3rd of May.
A former radio communications professional with National Disaster Medical
Services, he had a long government career that also included serving
as manager of the National Emergency Radio System of the Federal Emergency
Management Agency. He had also been a board member of the Amateur Radio
Safety Foundation, which funds and operates Winlink. Ross is credited
with being one of the creators of a Winlink network on a number of government
radio channels.
Ross wrote the National Interoperability Field Operations Guide published
by the US Department of Homeland Security and later served as program
manager of the department's Shared Resources HF Radio Program.
Licensed in 1974, he enjoyed DXing, contesting, automatic link establishment
and the digital modes. He had also held a General Radiotelephone Operator
License.
He was 67.
This is Travis Lisk N3ILS.

OPEN-SOURCE SOFTWARE MODEM CALLED A VARA REPLACEMENT
STEPHEN/ANCHOR: A US-based company has developed an open-source software
modem for HF Digital and other uses, as we hear from Paul Braun WD9GCO.
PAUL: Developers have announced the release of Mercury, an open-source
software modem that they are calling a replacement for Vara. Mercury
is a digital radio OFDM protocol, which can be used for HF broadcast
and peer-to-peer ARQ connections with compatible TCP interfaces.
According to Peter Bloom, general coordinator of the developer Rhizomatica,
Mercury is compatible with Windows, Linux and a number of non-Intel architectures.
Peter told Newsline that Mercury, the newest element of Rhizomatica's
HERMES software suite, it is built for reliable store-and-forward email
and file transfer over HF radio links. He said it is compatible with
most HF transceivers and it complies with ham radio use. The project
coordinator is Rafael Diniz, PU2UIT.
He said that Mercury has a number of advantages over Vara, including
improved performance over high-SNR links.
There is no license fee. Find additional details at the website that
appears in the text version of this week's report at arnewsline.org

WIA ASKS FOR CHANGES IN SUB-ANTARCTIC CALL PREFIXES
STEPHEN/ANCHOR: The Australian regulator is being asked to change some
callsign prefixes in the sub-Antarctic, as we hear from Graham Kemp VK4BB.
GRAHAM: The Wireless Institute of Australia has responded to the regulator's
request for input on its Five-Year Spectrum Outlook, spanning 2026 through
to 2031, and its Work Program, spanning 2026-2027. It is asking that
the Australian Communications and Media Authority improve spectrum access
to support experimentation and emerging technologies; modernise regulation
of repeaters and beacons; and develop a staged EME competence framework
that will give amateurs greater access to operating at increased power
safely. The WIA has been actively seeking greater power for hams since
2013. It told the ACMA that increased power for the class licence should
be backed up by training, certification and communications industry best
practices.
The WIA has also asked that the callsign prefixes be changed in the sub-Antarctic,
restoring VKØ for operations on Heard Island and Macquarie Island, which
are now assigned the VK9 prefix of Australian external territories. The
WIA is also proposing that the VK9 prefix be restored for Lord Howe Island,
which is presently assigned VK2.
The response to the consultation highlights ham radio's key role in STEM,
innovation and emergency communications, noting that a number of the
issues it has raised address barriers to ham radio's growth and operators'
participation and efficiency.
This is Graham Kemp VK4BB.

KICKER: A-ROVING THEY WILL GO
STEPHEN/ANCHOR: We end this week with the thought that, if one park is
fun to activate, two parks are twice as much fun Operators in Ireland
are trying for five times as much fun by doing their first Parks on the
Air rove - as a group activity. Dave Lee M7TLB takes us along for the
ride.
DAVE: Members of the TOG Hackerspace and South Dublin Radio Club are
no strangers to experimentation. Tinkerers, amateurs, makers and experimenters
all find a welcome home in Dublin where the ham radio club station, EIØTOG,
has its headquarters.
The radio operators are now working on yet another experiment - their
first POTA Rover Day - in the hope of activating five POTA designated
parks in a single UTC day, qualifying them for the POTA Rover Warthog
Award.
Their shared daylong adventure is planned for Sunday the 31st of May.
While they're not looking to bag an actual warthog - the tusks and tempers
of these sub-Saharan mammals can be quite intimidating - they are going
for five successful activations and as many QSOs as possible. As club
members note on the TOG Hackerspace website: [quote] "This could be a
great idea, or it could totally fall apart, but that is all part of the
fun. Amateur radio has always had that experimental side to it, and a
day like this has a real sense of adventure." [endquote] One ham plans
to take the spirit of adventure to the extreme. He hopes to make the
trip on his bicycle.
Be listening for EIØTOG and help them catch that warthog. This would
not only be the first such award for the club, it would be the first
warthog - wild or figurative - to actually find a habitat in the Republic
of Ireland.
This is Dave Lee M7TLB.
