THE FIRST AMATEUR RADIO STATION ON THE MOON, JS1YMG, IS NOW

TRANSMITTING

The Japan Aerospace Exploration Agency (JAXA) successfully landed their
Smart Lander for Investigating Moon (SLIM) on January 19, 2024. Just
before touchdown, SLIM released two small lunar surface probes, LEV-1
and LEV-2.

LEV-2 collects data while moving on the lunar surface, and LEV-1
receives the data.

The JAXA Ham Radio Club (JHRC), JQ1ZVI, secured amateur radio license
JS1YMG for LEV-1, which has been transmitting Morse code on 437.41 MHz
since January 19. The probe uses a 1 W UHF antenna with circular
polarization and is transmitting "matters related to amateur business."

Radio amateurs have been busy analyzing JS1YMG's signal, with Daniel
Estévez's, EA4GPZ, blog
<https://destevez.net/2024/01/trying-to-decode-lev-1/> introducing the
method and extraction results for demodulating Morse code from the
signal, as well as extracting the code string.

It's unclear how long signals will be heard. JAXA has said that SLIM
was not designed to survive a lunar night, which lasts about 14 days,
and is due to return in a few days.

SLIM was launched on September 6, 2023, and landed on January 19, 2024,
with the mission of analyzing the composition of rocks to aid research
about the origin of the moon. SLIM's landing made Japan the fifth
country to achieve a soft touchdown on the moon. The landing was
achieved with exceptional precision -- within 180 feet of its targeted touchdown location.

ARRL MIDWEST DIVISION CONVENTION, WINTERFEST

Newly licensed ham Charlie Hartley, KF0OOP, 18, is one of ARRL's newest members. He's majoring in sound engineering at Webster University in
St. Louis, Missouri, and is an accomplished musician, playing both bass
guitar and the upright string bass. Ham radio, live sound, and music
run in his blood; he's the grandson of Bob Heil, K9EID.

Charlie had been secretly studying for his license. After passing his
test, he revealed his new Technician-class privileges and call sign to
his famous-ham grandpa as a birthday surprise. The pair joined many
others at the ARRL Midwest Division Convention/Winterfest, which is
organized and sponsored by the St. Louis and Suburban Radio Club.

ARRL Midwest Division Vice Director Dave Propper, K2DP, personally took Charlie's membership application at the event. ARRL Director of
Emergency Management Josh Johnston, KE5MHV, was a keynote speaker for
the DX/ARRL Banquet at the event.

He said it was a good gathering to connect with hams in the
division. "Ham radio is alive and well in the heartland of America, and
it was encouraging to meet with so many members who were clearly
passionate about serving their community through amateur radio,"
Johnston said.

Several major manufacturers exhibited at the event, which was held at
the Gateway Convention Center in Collinsville, Illinois, on January 27.
The hamfest hosted the 2024 ARRL Midwest Division Convention.

HEIL SOUND DONATES EQUIPMENT TO W1AW

The Hiram Percy Maxim Memorial Station, W1AW
<https://www.arrl.org/w1aw>, at ARRL Headquarters in Newington,
Connecticut, has received a generous donation of equipment from the
Heil Ham Radio division <https://heilhamradio.com/> of Heil Sound <https://heilsound.com/>.

The company's founder, Bob Heil, K9EID, is a pioneering audio engineer
and avid radio amateur. At his direction, the company donated four Heil
Pro Set Elite HC-6 headsets, three Heil Pro Set 3 stereo headphones,
two Heil FS-3 press-to-talk foot switches, one Heil iCM microphone, one
Heil PR 30 microphone, and various adapters. The equipment has been
placed into service at the station for use by visiting operators <https://www.arrl.org/w1aw-operating-schedule>, and for the voice
bulletins <https://www.arrl.org/bulletins> transmitted each weekday
evening by W1AW.

W1AW Station Manager Joe Carcia, NJ1Q, says the gear is going to be of
great use. "We are fortunate to host many visiting operators each year,
but all that use takes a toll on the gear," he said. "The generosity of
Heil Ham Radio to help us keep the equipment fresh is greatly
appreciated."

ARRL FOUNDATION ACCEPTING GRANT APPLICATIONS IN FEBRUARY

The ARRL Foundation is now accepting grant applications from amateur
radio organizations for eligible amateur radio-related projects and initiatives, particularly those focused on educating, licensing, and
supporting amateur radio activities, to grow amateur radio's future, youth-based projects and initiatives are especially encouraged.

The ARRL Foundation grants program accepts proposals on a cyclical
model three times a year: in February, June, and October. Proposals for
the June grant period are accepted through February 29. Awardees will
be notified approximately 1 month after the closing of each cycle.

The Foundation, which celebrated 50 years of service last year,
carefully manages a portfolio of endowments where donors have provided
specific goals for their gifts, and that portfolio is invested and
managed in a way that it can continue to support those goals for many
years to come.

WINTER FIELD DAY A SUCCESS FOR OHIO CLUB

The Delaware Amateur Radio Association (DELARA) <http://k8es.org/> in
Delaware, Ohio, was one of many clubs who participated in this year's
Winter Field Day (WFD).

This was the second year DELARA worked WFD. Club member Joe
Papworth, K8MP, and three event station captains -- Ed Brady, AE8Q; Guy Merrill, KD8KWH, and Tom Foy, N4HAI -- provided support and helped set
up for the event.

"We had 16 participants this year and over 1,100 contacts," said
Papworth. "At least 200 more contacts than last year, and operators
were on most modes and bands."

DELARA members wrapped a shelter house at Delaware State Park with
plastic sheets to protect them from the winter weather, and the Elm
Valley Joint Fire District loaned them a generator to provide power for
the transceivers, as well as a few portable heaters. Three antennas and stations were set up inside.

house for the DELARA Winter Field Day event. [Photo courtesy for Joe

"WFD is a great experience and a chance to get on the air," added
Papworth. "We're planning on participating next year and looking
forward to [the] 2024 ARRL Field Day on June 22 - 23 <http://arrl.org/field-day>"

Winter Field Day (WFD) <https://winterfieldday.org/index.php>,
sponsored by the Winter Field Day Association, is open to participants worldwide. It's held on the last full weekend in January and is a communications exercise designed to help preparedness for disasters.

ARRL PODCASTS

On the Air
Sponsored by Icom <http://www.icomamerica.com/en/>

Maintaining a "junk box" -- a collection of odds and ends that can be
used in future projects and repairs -- is a time-honored practice among
hams. Every ham radio junk box has to start somewhere, though, and the
cover story of the January/February 2024 issue of On the Air, "A Fine
Mess: Starting Your Junk Box," by Eric P. Nichols, KL7AJ, offers advice
about how to do just that. The January 2024 episode of the On the Air
podcast digs deeper by going on location to the workshop of W1AW,
ARRL's Hiram Percy Maxim Memorial Station. Station Manager Joe Carcia,
NJ1Q, welcomes us into this working space to show us some real-life
junk boxes and discuss how they come in handy.

IN BRIEF...

February 17, 2024, marks the 160th anniversary of the sinking of the
USS Housatonic by the H.L. Hunley submarine. The event took place in
1864 in Charleston, South Carolina, and was the first successful
sinking of a warship by a submarine. The Trident Amateur Radio Club <https://www.tridenthams.org/hl-hunley/> will commemorate the submarine
by operating special event station N4HLH on Saturday, February 17,
2024, from Fort Moultrie on Sullivan's Island from 10:00 AM to 2:00 PM
EST. Proposed frequencies are 7.117 (CW), 7.262, and 14.262, as well as
28.462 MHz for Technician-class licensees. A QSL card will be available
for those who send a request with their contact information to
N4HLH/Trident Amateur Radio Club, PO Box 60732 N. Charleston, SC 29419.
A QSL card will be sent upon receipt of a SASE for US requests and a
SAE with 2 USD for international requests.

THE K7RA SOLAR UPDATE

Tad Cook, K7RA, of Seattle, Washington, reports for this week's ARRL Propagation Bulletin, ARLP005:

Seven new sunspot groups emerged this week, but solar activity was
lower. One new spot appeared on January 26, two more on January 28,
three more on January 30, and one more on January 31.

The average daily sunspot number dropped from 130.6 to 71.6, and the
average daily solar flux declined from 173.3 to 145.4. The average
planetary A index changed from 7.4 to 6.9, while middle latitude
averages increased from 5.1 to 5.6.

Next month, it looks like there will be a modest peak in solar flux at
175 on February 20.

Predicted solar flux is 135 on February 1; 140 on February 2 - 3; 145
on February 4 - 7; 165 on February 8 - 11; 170 on February 12; 165 on
February 13 - 15; 170 on February 16 - 19; 175 on February 20; 170,
165, 160, 150, 140, 135, and 140 on February 21 - 27; 145 on February
28 - 29, and 150 on March 1 - 2.

The predicted planetary A index is 8 and 5 on February 1 - 2; 8 on
February 3 - 5; 5 on February 6 - 16; 8 on February 17 - 18; 5 on
February 19 - 24; 10, 12, and 10 on February 25 - 27, and 5 on February
28 through March 2.

there will be a cycle peak this year.

Read about a powerful solar flare causing a radio blackout at https://bit.ly/3HGWYfn.

FXStreet reports on how you can leverage the solar cycle for investing
at https://bit.ly/3UodRTE, but I'm skeptical.

Sunspot numbers for January 25 - 31, were 101, 97, 52, 75, 48, 53, and
75, with a mean of 71.8. The 10.7-centimeter flux was 160.5, 156.7,
148.1, 141.1, 140.3, 135, and 136.2, with a mean of 145.4. Estimated
planetary A indices were 6, 6, 5, 8, 9, 8, and 6, with a mean of 6.9.
The middle latitude A index was 4, 4, 4, 5, 7, 8, and 7, with a mean of
5.6.
