IARU Approves two Digipeating Amateur Satellites

The International Amateur Radio Union (IARU) has coordinated two European
digipeating satellites that are scheduled to launch in fall 2023. At the
Technical University of Košice in Slovakia, satellite Veronika, a 1U
CubeSat, is scheduled for launch on a Falcon 9 launcher on the Transporter
9 mission in October 2023.

The satellite will be equipped with a 24/7 digipeater on two different
bands, as well as experimental slow-scan digital video (SSDV)
transmissions. There is an education and outreach mission planned to
involve Slovak grammar and high schools, and to transmit special CW and
AX.25 messages on several special occasions. The satellite will be equipped
with a novel Attitude Determination and Control System (ADCS) subsystem,
including electromagnetic actuators and a global navigation satellite
system (GNSS) receiver. This will also help to identify the satellite
during the first days and weeks of orbit.

The satellite will communicate using Spacemanic's
<https://www.spacemanic.com/> well-known Murgas transceivers (BDSat-1,
BDSat-2, Planetum-1). Altogether, Veronika will provide: AX.25 telemetry, a
CW beacon, a digipeater, AX.25 and CW messages on special occasions for
community engagement, experimental SSDV transmissions, SatNOGS
<https://satnogs.org/> integration, a decoder, and a dashboard. A downlink
on 436.680 MHz has been coordinated, and it will use 9k6 G3RUH AX.25 and a
CW beacon. A SpaceX launch on the Transporter 9 mission will send the
satellite to a 500/600-kilometer polar orbit.

The Romanian Federation of Amateur Radio (FRR <http://www.hamradio.ro/>) is
preparing the ROM-3 for launch in October or November 2023. ROM-3 is a 50 x
50 x 100-millimeter picoSAT with three missions and objectives. Its primary
mission is to act as a digital amateur radio repeater. Its secondary
mission is to transmit low-resolution SSDV images in a Gaussian frequency
shift keying* (*GFSK) mode. The tertiary mission is to transmit a CW beacon
that will help amateur radio operators detect the presence of the satellite
and measure basic properties of the signals, such as its strength, fading
due to spinning, and Doppler to measure speed. A downlink on 436.235 MHz
has been coordinated for 20 WPM on CW, 500 (bps) GFSK telemetry, and 5
(kBps) GFSK SSDV. A SpaceX launch will send ROM-3 into a 500-kilometer
polar orbit.
New ARRL Propagation Book Offers Tools for Solar Cycle 25

Get an understanding of propagation by reading *Here to There: Radio Wave
Propagation.*
<https://home.arrl.org/action/Store/Product-Details/productId/2010547491>
Available now from ARRL.

"Learning about propagation will make you a more effective operator and
station builder," said Ward Silver, N0AX, editor of ARRL's newest book, *Here
to There: Radio Wave Propagation*
<https://home.arrl.org/action/Store/Product-Details/productId/2010547491>.
"It's a key part of 'radio know-how.'"

Silver and contributing editors present the principles of signal
propagation in an easy-to-understand style. Other contributors include Carl
Luetzelschwab, K9LA; Dr. Nathaniel A. Frissell, W2NAF; Frank Donovan,
W3LPL; Ethan Miller, K8GU, and Hermann Schumacher, DF2DR.

*Here to There: Radio Wave Propagation* provides practical advice for
understanding what's going on in the ionosphere and troposphere, how
takeoff angle impacts your transmission, how far you can really communicate
over VHF and UHF, and much more. Understanding ionospheric structures, how
they form, and which bands they interact with will prepare you for
practical operating and help you make the most of your time on the air. The
book is timely, introduced as Solar Cycle 25 is in its upswing.

------------------------------
In Brief...

*The 3rd annual Masonic Lodges on the Air (MLotA), an amateur radio special
event, will occur on Saturday, September 23, 2023, from locations across
the United States.* The event is open to all amateur radio operators. The
idea for the event grew from the realization that many Freemasons also have
a love for amateur radio. The Fulton County Amateur Radio Club
<https://fcarc.com/> and Ohio's Fulton Lodge #248 first hosted the event in
2021. The mission is to promote fraternal bonds within the ranks for Free
and Accepted Masonic lodges and its many amateur radio operators, who are
also brothers in the fraternity while encouraging contact with amateur
radio operators around the state, county and world. The event will take
place from 10:00 AM - 6:00 PM ET, on 80 - 40 - 20 -15, and 10 meters SSB.
Amateur radio participants are asked to honor all band plans, and all
contacts must be on the phone portion of the bands. Stations may be
contacted once on each band. Complete contest rules and more information
can be found at cqmorelight.com/rules. <http://cqmorelight.com/rules>

events and commemorations.

*Minutes of the Second Meeting of the ARRL Board of Directors are now
published.* The meeting was held July 21 - 22, 2023 in Windsor Locks,
Connecticut. Among the decisions approved at the meeting was a new dues
rate, effective January 1, 2024. The minutes are available at
www.arrl.org/board-meetings.

*The 2022 ARRL Annual Report has been published.* This yearly summary
details accomplishments of our member-volunteers. Included is ARRL's *Report
to America*, which highlights the contributions made by radio amateurs to
their local communities. It may be especially valuable to amateur radio
clubs and emergency communications groups to help tell the story of good
works done by hams. Communications responses for New England blizzards,
Oklahoma tornadoes, Colorado wildfires, and Hurricane Ian are detailed in
the report which may be viewed at this link

The K7RA Solar Update

Tad Cook, K7RA, of Seattle, Washington, reports for this week's ARRL
Propagation Bulletin, ARLP032:

Solar disk image taken August 10, 2023, courtesy of NASA SDO/HMI.

Two new sunspot groups appeared on August 3, and then three more appeared
on August 7, followed by another on August 9.

But solar activity was lower during our current reporting week of August 3
- 9, with the average daily sunspot number dropping from 154.3 to 108.9,
and average solar flux from 173 to 166.4.

The average daily planetary A index rose from 8.3 to 12.3, and the average
middle latitude A index rose from 9.3 to 10.1.

The middle latitude A index on August 3 - 4 was not available, so I
estimated the value based on the planetary A index and remaining five
middle latitude readings for the rest of the week.

Predicted solar flux is 150 on August 10 - 12; 145, 140, 130, and 135 on
August 13 - 16; 162 on August 17 - 18; 164 on August 19 - 20; 168 on August
21 - 23; 172, 172, and 170 on August 24 - 26; 172, 172, and 174 on August
27 - 29; 172, 172, and 170 on August 30 - September 1; 168, 168, 166, and
164 on September 2 - 5, and 162, 162, 164, and 164 on September 6 - 9.

Predicted planetary A index is 12 on August 10; 5 on August 11 - 14; 12 and
8 on August 15 - 16; 5 on August 17 - 25; 12 on August 26, and 5 on August
27 - September 4.

On August 9, Spaceweather.com <https://spaceweather.com/> wrote about a
1940 geomagnetic storm that sounds similar to the infamous Carrington Event.

Two coronal mass ejections hit Earth, each 109 minutes apart. Read a recent
scientific paper on the event at https://bit.ly/3s1VrMh.

Space weather forecaster Dr. Tamitha Skov, WX6SWW, recently uploaded this
video:

https://youtu.be/Olfjss8GmSI

Sunspot numbers for August 3 - 9, 2023, were 124, 122, 100, 97, 101, 115,
and 103, with a mean of 108.9. The 10.7-centimeter flux was 162.9, 170.8,
175.8, 173.5, 169.7, 158.9, and 153.4, with a mean of 166.4. Estimated
planetary A indices were 6, 13, 36, 4, 12, 8, and 7, with a mean of 12.3.
Middle latitude A index was 5, 12, 24, 4, 11, 7, and 8, with a mean of 10.1.
