IARU HF World Championship is Major Mid-Year Event for Everyone
The International Amateur Radio Union (IARU) HF World Championship over
the July 11 - 12 weekend offers an opportunity for operators to put
their stations to the test ahead of the fall-winter contest season.
Casual contesters are welcome. This everybody-works-everybody event
kicks off at 1200 UTC on Saturday, July 11, on 160, 80, 40, 20, 15, and
10 meters and continues for the next 24 hours. Despite rather dismal HF
conditions recently, the competition is expected to keep the bands
hopping on both phone and CW; participants may operate either or both
modes. Highlighting the activity will be the IARU headquarters (HQ)
stations and officials on the air from around the world, although, as
the IARU notes, HQ stations may not be active at typical levels.
Carol Milazzo, KP4MD, competed with
her low-power portable setup in the
2019 IARU HF World Championship.
Participating stations send a signal report and ITU zone (or IARU
member-society abbreviation). The IARU HF Championship web page
includes ITU zone borders for the US and Canada.
"It is essential that the global COVID-19 pandemic be taken into
account, including by IARU member-society HQ station teams," the IARU
said in announcing this year's event. The IARU stressed that
multioperator and IARU member-society HQ stations "must adhere strictly
to the regulations and social distancing guidelines in effect issued by
the responsible health authorities and the World Health Organization,
even if observing the guidelines is not legally required in their
locations." This requirement also applies to single-operator stations
and especially to stations hosting guest operators.
The objective of the IARU HF World Championship is "to support amateur
self-training in radiocommunications including improving amateur
operating skills, conducting technical investigations, and
intercommunicating with other amateurs around the world, especially
IARU member-society headquarters stations." Special rules governing
IARU member-society HQ stations permit using multiple sites, if
national regulations permit.
The Vakarel broadcast
transmitter tower and two
smaller antennas. HQ station
LZ0AA will use this for an
80-meter antenna.
The HQ list includes ARRL. Members of the Tennessee Contest Group (TCG)
will operate as ARRL HQ station W1AW/4, while IARU HQ Station NU1AW
will be operated remotely by a team of operators using WW2DX facilities
on the coast of Maine.
In addition to HQ stations, members of the IARU ministrative Council
(AC) and the three IARU regional executive committees will send AC, R1,
R2, and R3, as appropriate. IARU President Tim Ellam, VE6SH, will be
active for a limited period, giving out the AC multiplier. IARU
HQ/official stations and ITU zones are multipliers, which count per
band but not per mode, but contacts count per mode per band. Contacts
with IARU member-society HQ stations and officials do not count as zone
multipliers.
Listen for this one: In Bulgaria, the Vakarel broadcast transmitter has
been off the air since 2015. The antenna, erected in 1937, is 215
meters (705 feet). During the IARU contest, the Bulgarian Federation of
Radio Amateurs (BFRA) HQ station will use the antenna on 80 meters as
LZ0AA. After the contest, the antenna will be taken down. -- Thanks to

Maritime Mobile Service Network Comes to the Aid of Vessel in Distress
The Maritime Mobile Service Net (MMSN) on 14.300 MHz came to the
assistance of a sailing vessel in distress on June 25. MMSN control
operator Steven Carpenter, K9UA, took a call on 20 meters from Ian
Cummings, KB4SG, the skipper of the Mystic Lady, then some 40 miles
east of Florida. Cummings reported that his engine had failed as he was
attempting to return to his home port of Stuart, Florida. He not only
had insufficient wind, but a strong current was carrying the vessel out
to sea.
Cummings had been unable to reach any station via his VHF marine radio,
because he was too far from the coast. Assisting in the call was Robert
Wynhoff, K5HUT, also an MMSN net control operator. Cummings said his
vessel, with one passenger on board, was drifting northwest toward the
South Carolina coast.
"A major concern was that the vessel was heading directly towards a lee
shore," the MMSN reported. "Lee shores are shallow, dangerous areas
which are a hazard to watercraft. Vessels could be pushed into the
shallow area by the wind, possibly running aground and breaking up."
Carpenter contacted Cummings' family, who had already called the Sea
Tow marine towing service. Sea Tow advised Carpenter to tell the
captain to head closer to shore by sailing west, if possible. Carpenter
told Cummings that if he was unable to get nearer to shore, he would
notify the US Coast Guard, which was already monitoring the situation.
As the MMSN reported, "The Mystic Lady was able to make some headway,
but it was very slow. Members of the MMSN made additional calls via
landline to the captain's family as to the ongoing status of those on
board. The family was concerned but relieved that communication was
established and that all were well."
Several hours later, the captain advised that the wind had picked up,
allowing him to head close enough to shore for Sea Tow to reach the
vessel and take it back to port.
The Pacific Seafarers' Net, which monitors 14.300 MHz from the West
Coast after the MMSN secures at 0200 UTC, kept in touch with the Mystic
Lady into the night while it was under tow.
The tired, grateful captain later messaged the net, "A million thanks
to everyone last night who helped rescue us on 14.300. Everyone chipped
in as we drifted north in the Gulf Stream 60 miles headed to a lee
shore. The MMSN net control and several others stayed with us for
hours, phoned people, and were immensely helpful. The situation on
board was dangerous. We are now safely under tow home. You folks are
amazing!"
In operation since 1968, the MMSN monitors 14.300 MHz 70 hours a week
to assist vessels and others in need of assistance. -- Thanks to MMSN
Net Manager Jeff Savasta, KB4JKL
Newer Solar Cycle 25 Forecast Runs Counter to Consensus
Scientists associated with the National Center for Atmospheric
Research, the University of Maryland, NASA Goddard Space Flight Center,
and other institutions are offering a "bold prediction" on how Solar
Cycle 25 will play out. In a paper, "Overlapping Magnetic Activity
Cycles and the Sunspot Number: Forecasting Sunspot Cycle 25 Amplitude,"
they assert that the next sunspot cycle will be of major proportions.
The forecast stands in stark contrast to the consensus of forecasters
who predict that the magnitude of the nascent Cycle 25 may not be much
different from the current unremarkable solar cycle, which appears to
have reach its low point.
"From the dawn of modern observational astronomy, sunspots have
presented a challenge to understanding -- their quasi-periodic
variation in number, first noted 160 years ago, stimulates
community-wide interest to this day," the abstract points out. "A large
number of techniques are able to explain the temporal landmarks,
(geometric) shape, and amplitude of sunspot 'cycles,' however,
forecasting these features accurately in advance remains elusive."
Monthly sunspot numbers since
1749. The data values are
represented by dots, and the
12-month running average values
are illustrated as a red shaded
area. Vertical blue dashed lines
signify the magnetic activity
cycle termination times that
trigger the rapid growth of
sunspot activity.
The paper notes that recent studies have illustrated a relationship
between the sun's 22-year Hale magnetic cycle and the production of
sunspot cycle landmarks and patterns, but not the amplitude of the
cycle.
"Using discrete Hilbert transforms on 270 years of monthly sunspot
numbers to robustly identify the so-called 'termination' events --
landmarks marking the start and end of sunspot and magnetic activity
cycles -- we extract a relationship between the temporal spacing of
terminators and the magnitude of sunspot cycles," the abstract
explains. "Given this relationship and our prediction of a terminator
event in 2020, we deduce that Sunspot Cycle 25 will have a magnitude
that rivals the top few since records began. This outcome would be in
stark contrast to the community consensus estimate of Sunspot Cycle 25
magnitude."
NASA's Solar Dynamic Observatory
captured this image of a sunspot,
with a core larger than Earth.
According to the paper, low-amplitude solar cycles appear to correspond
with widely separated terminators, while larger-amplitude cycles
correspond to more narrowly separated terminators.
"[O]ur best estimate for the [sunspot number] amplitude of Solar Cycle
25 is 233 spots, with a 68% confidence that the amplitude will fall
between 204 and 254 spots," the paper posits. "We predict with 95%
confidence that the Cycle 25 amplitude will fall between 153 and 305
spots."
The researchers concede that their forecast is outside of the
scientific consensus, based on different paradigms. "Over the coming
months, as [Solar Cycle] 25 matures, it will become evident which of
these paradigms is most relevant," the paper says. "Very early
indications of the spot pattern are appearing at higher-than-average
latitudes (ƒ*¬40Aø). Historically, high-latitude spot emergence has
been associated with the development of large amplitude sunspot cycles
-- only time will tell."
ARRL Podcasts Schedule

The latest episode of the Eclectic Tech podcast (Episode 11), available
on Thursday, July 2, will cover Shortwave Radiogram, web-based remote
receivers, and PSKreporter.
The On the Air and Eclectic Tech podcasts are sponsored by Icom. Both
podcasts are available on iTunes (iOS) and Stitcher (Android) as well
as on Blubrry -- On the Air | Eclectic Tech.
The K7RA Solar Update
Tad Cook, K7RA, Seattle, reports: We saw a new sunspot on July 4, but
it was from the declining Solar Cycle 24 and lasted only through the
next day. Sunspot numbers were 12 and 11, for an average daily sunspot
number of 3.3 for the week. Prior to July 4, no sunspots had been
observed since June 15.
The average daily solar flux was 68.5; the previous week, it was 68.6.
The average daily planetary A index inched up from 4.7 to 5.1, and the
average daily middle latitude A index shifted from 4.7 to 6.4.
The 45-day outlook for solar flux does not look promising, with no
values predicted at 70 or above. Predicted solar flux is 68 on July 9 -
24; 69 on July 25 - August 8; 68 on August 9 - 20, and 69 on August 21
- 22.
Predicted planetary A index is 8 on July 9; 5 on July 10 - 12; 8 on
July 13; 5 on July 14 - 26; 8 on July 27 - 28; 5 on July 29 - 30; 12,
10, 8, and 8 on July 31 - August 3, and 5 on August 4 - 22.
Sunspot numbers for July 2 - 8 were 0, 0, 12, 11, 0, 0, and 0, with a
mean of 3.3. The 10.7-centimeter flux was 68, 69.3, 69.5, 69.4, 68.5,
67.7, and 67.2, with a mean of 68.5. Estimated planetary A indices were
4, 4, 7, 10, 5, 4, and 2, with a mean of 5.1. Middle latitude A index
was 5, 5, 9, 13, 6, 5, and 2, with a mean of 6.4.
A comprehensive K7RA Solar Update is posted Fridays on the ARRL
website. For more information concerning radio propagation, visit the
ARRL Technical Information Service, read "What the Numbers Mean...,"
and check out K9LA's Propagation Page.

QSO Today Virtual Ham Expo Announces Full Lineup of Speakers
The first QSO Today Virtual Ham Expo, which takes place the weekend of
August 8 - 9, has confirmed what it's calling "a packed lineup of over
70 great speakers" for the ARRL-sanctioned event. Attendance is free
and registration is open.
Presentations will cover a range of topics, with two tracks focused on
providing hands-on, practical advice for those just getting started in
amateur radio. Steve Johnston, WD8DAS, will demonstrate basic soldering
techniques for repairing equipment and building projects. Marcel
Stieber, AI6MS, will offer an overview of common battery types,
discussing the pros and cons of each -- including battery chemistry,
common uses and misuses, and everyday application tips.
For experienced operators, topics will cover new techniques, equipment
upgrading, 3D printing, and more. Glenn Johnson, W0GJ, will attempt to
answer the question, "Is 3 dB Worth a Divorce?" and cover a wide range
of antenna topics. Jim Veatch, WA2EUJ, will explain how to build a QRP
radio. In his presentation, "The Slot Antenna -- Undiscovered Country
for Most Hams," John Portune, W6NBC, will demonstrate how a satellite
TV dish can be "slotted" to make an effective outdoor 2-meter or UHF
antenna for use in antenna-restricted neighborhoods.
Prominent youth educator Carole Perry, WB2MGP, will moderate a lineup
featuring amateur radio's future leaders. Audrey McElroy, KM4BUN, will
speak on "Getting Girls Involved in STEM, Specifically Amateur Radio!",
while hot-air ballooning will be the focus of a talk by Jack McElroy,
KM4ZIA, "Highly Flying Kids with HAB."
QSO Today's Eric Guth, 4Z1UG, says that one challenge to any ham radio
convention, whether in person or virtual, is keeping the content of
presentations from becoming overly complicated and overwhelming. "For
our inaugural virtual Expo, we've made sure that there are great
speakers for both beginners and experienced hams," Guth said. "We've
asked all of our speakers to be laser focused on their topics while
providing hands-on, practical advice." Each presentation will wrap up
with a live question-and-answer session.
For more information or to register, visit the QSO Today Virtual Ham
Expo website. Attendance is free, and there are early bird prize
incentives for registering by July 24.

Washington Club Conducts Outdoor Amateur Exam Session
Parking lots may be replacing community centers, schools, and
clubhouses as convenient locations to conduct amateur radio examination
sessions. On June 20, the Mike and Key Amateur Radio Club in Washington
took over a Boeing parking lot to administer tests under the ARRL
Volunteer Examination Coordinator (ARRL VEC). Volunteer Examiner Scott
Robinson, AG7T, said his team had been unable to administer exam
sessions since early March.
"Based upon King County and Washington State COVID guidance, we thought
we could give an outdoor session using one of Boeing's parking lots in
Renton," Robinson told ARRL. "That required a lot of work to organize."
Volunteer examiners at the June 20
session included K7PIA, AG7T, KL7WM,
KD7IQL, KF7RWA, W7GIL, and K7CMW.

Robinson said the team developed a COVID-19 mitigation plan that
detailed how the examiners would address several major areas. These
included health screening of VEs and exam candidates, social distancing
in all aspects of the session, sanitation in setting up the test area
and in session processes, and contact tracing.
"With those details agreed to, an information document was produced for
the examinees that listed a set of requirements each of them needed to
meet," Robinson said. "For example, no carpooling to the session. Each
examinee who agreed to the requirements was then registered for the
session." Candidates had to register in advance via email, at which
time they would receive directions to the exam session location and
requirements.
A custom set of test booklets were produced for single use and then
disposed of. "We used plastic sheet protectors to ensure minimal
handling of examinees' documents by the VEs," Robinson explained.
"These were also thrown away."
Examinees parked in every other parking spot, facing the VE area in the
center of the lot. This allowed the VEs to supervise those taking exams
by looking through car windows.
"We had 24 examinees at the session and gave 29 exams, leading to 14
Technicians, seven Generals, and two Amateur Extras," Robinson said,
noting that an additional 10 candidates are on the waiting list. "We
are going to do this again on the third Saturday in July."
Annual KPH "Night of Nights" Canceled
The Maritime Radio Historical Society (MRHS) and the National Park
Service have announced that the annual KPH Night of Nights has been
canceled due to COVID-19 precautions. This would have been the 21st
such event, which commemorates what is believed to be the last
commercial Morse transmission in the US.
Maritime Radio Historical Society
founder Richard Dillman, W6AWO,
keyed the initial commemorative
broadcast during Night of Nights XX
while volunteer engineer Roy
Henrichs, WB6OVV, read the message
aloud to attendees.
While KPH, KFS, and K6KPH will not be on the air for Night of Nights
XXI, MRHS members will be active from home. Members will use their own
call signs on the usual K6KPH frequencies of 3550, 7050, and 14,050 kHz
starting at 0001 UTC on July 13 (the evening of July 12 in North
American time zones) and will send the Night of Nights opening message
traditionally transmitted via KPH. They will then stand by for calls or
will call "CQ NON" or "CQ Night of Nights."
Listen for WB6OVV, N6BBF, WB6UZX, AA6IF, N6AD, W6AWO, W6DHM, and
possibly others.
In Brief...
AMSAT has announced the 2020 Board of Directors slate of candidates.
The following candidates for seats on the AMSAT-NA Board of Directors
have been found to have their membership in good standing and their
nomination credentials in order: Howard DeFelice, AB2S; Mark Hammond,
N8MH; Jeff Johns, WE4B; Robert McGwier, N4HY; Bruce Paige, KK5DO, and
Paul Stoetzer, N8HM. AMSAT will elect three voting members of the Board
this year, with seats going to the three candidates receiving the
greatest number of votes. Two alternates will be chosen, based on the
next highest number of votes received. Ballots will be mailed to AMSAT
members by July 15. -- Thanks to AMSAT News Service via AMSAT Secretary
Brennan Price, N4QX
ARRL Central Division Director Kermit Carlson, W9XA, points out that a
new Indiana "hands-free" driving law carves out an exception for ham
radio mobile operation. "The hands-free law applies to electronic
communications devices which includes cell phones, tablets, and
smart-watches," a Q&A on the law explains. "Amateur radio, two-way
radio, and citizens band (CB) may be used under the hands-free law, but
drivers are required to do so in a safe manner." The Q&A notes that
"holding a smartphone or tablet while driving is a significant factor
in crashes caused by distracted driving."
A special event will celebrate the 40th anniversary of Vanuatu's
independence On July 30, 1980, the Republic of Vanuatu gained its
independence. France and the UK claimed parts of the archipelago, and
in 1906, they agreed on a framework for jointly managing it as the New
Hebrides. In celebration of the 40th anniversary of independence, all
three members of the Vanuatu Amateur Radio Society (VARS) will operate
special event station YJ40IND during the month of July. Activity will
be according to the individual operators' schedules, but is expected to
occur mostly during late afternoons and evenings (0600 - 1000 UTC). A
greater emphasis will be made over weekends and on Independence Day,
July 30. Operators should look for activity on 40, 20, and 15 meters,
where propagation is expected. On FT8 (normal or as the Fox) will be
Rod, YJ8RN. On SSB will be Estelle, YJ8ED. On CW, listen for Colin,
YJ8CW. Operators will be running 100 W. -- Thanks to The Daily DX
