GEOCHRON ATLAS 2 4K DONATED TO ARRL

Geochron <https://www.geochron.com/>, headquartered in Oregon City,
Oregon, has donated a Geochron Atlas 2 4K - a digital Geochron world
clock - to ARRL The National Association for Amateur Radio <http://www.arrl.org/>®.

Geochron Owner Patrick Bolan is on the fourth leg of a cross-country motorcycle trip during which he has supported Geochron installations at
MIT in Massachusetts, NASA Goddard Space Flight Center in Maryland, the
US Naval Observatory in Washington, D.C., the University of Delaware,
and the University of Vermont. Bolan arranged the donation for
installation at the ARRL Headquarters station, W1AW
<http://www.arrl.org/w1aw>.

The digital Geochron displays the Earth with sunrise and sunset
rendered in real time. "The device is a small computer that plugs
directly into any HDMI port on your TV via a short cable," wrote
reviewer Pascal Villeneuve, VA2PV in the February 2022 edition of QST.
"It offers several standard base maps, including a ham radio map set
with DXCC country prefixes and CQ zones. There are several data layers,
with some using live updates from the internet. Layers can be turned on
and off and adjusted by the viewer using the included remote. It's very
simple to set up and operate." A subscription to a premium bundle
supports real-time data for radio amateurs including live propagation information, AMSAT satellite tracking, and Maximum Usable Frequency
overlays.

"We're honored that ARRL has received the donation of a digital
Geochron," ARRL Director of Operations Bob Naumann, W5OV, said. "Its
beautiful maps of the Earth and the utility of so much displayed
information will be a treat for members to see and use when visiting
the station. ARRL thanks Patrick Bolan for arranging this donation and
for Geochron's support."

ULRICH L. ROHDE, N1UL, TO RECEIVE ENGINEERING ACHIEVEMENT AWARD

ARRL The National Association for Amateur Radio <http://www.arrl.org>®
is pleased to recognize Dr. Ulrich L. Rohde, N1UL, as the 2022
recipient of the Institute of Electrical and Electronics Engineers
(IEEE) Photonics Society Engineering Achievement Award. The award is
for outstanding engineering achievement in the field of optoelectronic
signal generation and optical measurement equipment for next-generation intelligent optical networks. Dr. Rohde is an ARRL Maxim Society and
Life Member.

Dr. Rohde is currently a partner of Rohde & Schwarz, in Munich,
Germany, and Chairman of Synergy Microwave Corporation in Paterson, New
Jersey. He is also President of the Communications Consulting
Corporation, serving as an honorary member of the Senate of the
University of the Armed Forces in Munich, honorary member of the Senate
of the Brandenburg University of Technology Cottbus-Senftenberg, and
past member of the Board of Directors of Ansoft Corporation in
Pittsburgh, Pennsylvania.

Throughout his career he has been active in microwave technology, and
in 2017 was honored for his work developing software-defined radio
(SDR).

Dr. Rohde has been an avid amateur radio operator holding several
licenses in the United States and Germany. He has been licensed since
1956 and involved mostly in technology and systems. In 2015, he won
first place in the ARRL DX Contest in the Northern New Jersey Section.
He also operates N1UL/MM on his yacht, the Dragonfly, and is Trustee of
the Marco Island Radio Club, K5MI.

"We congratulate Dr. Rohde on this prestigious award," said ARRL
Laboratory Manager Ed Hare, W1RFI. "We in the amateur radio community
have long benefited from Dr. Rohde's expertise. His advice and guidance
on technical procedures and his generosity have been invaluable to ARRL
members and our Lab." In 2021, Rohde donated <http://www.arrl.org/arrlletter?issue=2021-02-18#toc03> a Rohde &
Schwarz SMBV100A vector signal generator to the ARRL Lab.

Dr. Rohde will receive the 2022 Engineering Achievement Award at the
IEEE Photonics Conference in November in Vancouver, British Colombia,
Canada.

AMATEUR RADIO TO BE SHOWCASED AT 2022 EAA AIRVENTURE IN OSHKOSH,

WISCONSIN

ARRL member-volunteers will ensure amateur radio is well-represented at
the annual EAA AirVenture in Oshkosh, Wisconsin, on July 25 through
July 31. More than 10,000 aircraft and a half-million flight
enthusiasts make Wittman Regional Airport the busiest airfield in the
world during AirVenture.

ARRL has participated at AirVenture since 2018, supporting an exhibit
that encourages pilots and aviation enthusiasts to discover radio communications and radio technology through ham radio. ARRL Director of
Public Relations and Innovation Bob Inderbitzen, NQ1R, has organized a
booth (#2152 in Hangar B) and an all-volunteer team.

"There's a kinship among the aviation and amateur radio communities," Inderbitzen said. "In addition to introducing newcomers to ham radio,
we expect to meet hundreds of ham-pilots at AirVenture. This is a great opportunity to show off ham radio at such a large-scale event."
Frederick Hart, AA0JK, and Bob Inderbitzen, NQ1R, wrote "Growing
Amateur Radio, One Pilot at a Time," in the January 2019 issue of QST, describing some of the opportunities and experiences pursued by pilots
who become active ham radio operators.

At KidVenture, a highlight for children attending AirVenture, kids
can build and take home a radio receiver to listen to air traffic and
other nearby transmissions from approximately 65 - 140 MHz. The kit,
designed by student engineer Levi Zima, KN4YHS, with additional support
from his sister, Kirsten Zima, KC9RWG, has been an ARRL offering since
2021 (see ARRL's Introduction to Radio Receiver Kit <https://home.arrl.org/action/Store/Product-Details/productId/133264>).
"It's great fun to see children at AirVenture walking around with the
radio kits they've built and tuning in to the busy Air Traffic Control
Tower throughout the event," said Inderbitzen. "Radio communications is
a key part of learning about avionics. ARRL is grateful to EAA
AirVenture for sponsoring the activity, which promises to introduce a
lot of young people to radio."

RICHARD WILLIAM EHRHORN, W4EA, SK

Richard William Ehrhorn, W4EA, passed away on June 26, 2022. An ARRL
Life Member, Ehrhorn was first licensed in 1947 and founded Signal/One.
He and Eugene Chenette, N5YJ (SK), designed, manufactured, and marketed
the then state-of-the-art, high-end Signal/One CX7 multiband
transceiver in the late 1960s. He also founded Ehrhorn Technological Operations, Inc. and was Chairman of Alpha/Power, Inc.

He graduated from the University of Minnesota in 1955 with a BS in
Electrical Engineering, and in 1958 he received his MS in Electrical Engineering from the California Institute of Technology.

Ehrhorn was a licensed amateur radio operator for over 70 years, an
ARRL Life Member, and throughout his career in radio technology, was
well known for designing and building RF amplifiers.

In his QRZ database biography, Ehrhorn wrote about his respect and competitiveness with Art Collins, founder of the Collins Radio Company
in 1933. "I always had aimed to replicate in a small way Art Collins'
success: build the finest ham radio gear and -- someday -- government
and/or industrial customers would 'discover' us," Ehrhorn wrote. Then
in 1983, Ehrhorn was invited by General Electric Medical Systems to
design a linear RF amplifier to work with their new magnetic resonance
imaging (MRI) technology.

Ehrhorn retired to Forest, Virginia, where Brian Justin, WA1ZMS, began
to know Ehrhorn and his work in more detail. "He was a man of a lot of
firsts and high-water marks," said Justin. "His claim to fame was
certainly the development [of] the Alpha Series RF power amplifiers
that made their way into medical technology."

Justin added that Ehrhorn, in his later years, was still active in
amateur radio, especially on the HF bands. On his move to a new
location, Ehrhorn wrote, "New QTH, 58 acres with a broad hilltop 0.2
miles high! We still can see for miles in all directions. And I finally
have room for decent 75 - 80 and 160-meter antennas. Better late than
never." Several years ago, a tornado barely missed Ehrhorn's house,
leaving his towers and antennas intact.

Amateur radio drove Richard Ehrhorn's passions and creativity
throughout his career.

IN BRIEF...

The 2021 ARRL Technical Innovation Award honors Wojciech Kaczmarski,
SP5WWP, for developing a new digital radio communication protocol, M17 <https://m17project.org/>, for the good of amateur radio. M17 is a new open-source and patent-free digital radio protocol with a goal to
provide a fully sustainable option for digital radios in the future.
ARRL member Ed Wilson, N2XDD, the Community Manager of the M17 Project, accepted the 2021 Technical Innovation Award plaque on behalf of
Kaczmarski when Wilson visited ARRL Headquarters on Tuesday, July 12,
2022. The award plaque is being shipped to Kaczmarski in Poland. The
efforts of Kaczmarski and other M17 community team members have led to
the development of DroidStar, an Android application by Doug McLain,
AD8DP. The protocol has also been incorporated within other amateur radio-related projects to help advance the radio art.

ARRL is seeking a Public Relations & Outreach Manager for employment at
our headquarters in Newington, Connecticut. The manager will be
responsible for increasing the awareness and value of the Amateur Radio
Service to the public at large, for promoting the value of ARRL and the contributions of its member-volunteers, and for developing outreach opportunities that support awareness and growth of amateur radio. The
ideal candidate will be a storyteller who is adept at writing content
and developing campaigns to convey our message to various audiences.

THE K7RA SOLAR UPDATE

Tad Cook, K7RA, of Seattle, Washington, reports for this week's ARRL Propagation Bulletin ARLP028:

Rising solar activity over the past reporting week, July 7 - 13, 2022,
was reflected in increased sunspot numbers, solar flux, and rising
geomagnetic activity.

Average daily sunspot numbers increased from 62.6 to 102.1, with the
peak value at 134 on Monday, July 11. Average daily solar flux rose
from 103.5 to 147.4, with peak values at 164.9 and 164.8 on Tuesday and Wednesday.

New sunspots emerged on July 7, July 10, and July 11. Total sunspot
area peaked on July 11.

Planetary A index averaged out at 12.4 (up from 9.8 last week) while
the middle latitude A index went from 9.7 to 10.6.

Toward the end of the day on July 7, Alaska's college A index was 46 (a
very high value), while the last four K index readings of the same day
and the next two were 6, 6, 7, 5, 5, and 5.

This was caused by a corotating interaction region, sparking a G1-class geomagnetic storm.

Visit the following links for info on corotating interaction regions:

https://bit.ly/3P91Xrp

https://bit.ly/3IBOtlm

https://bit.ly/3yDwxlU

The Wednesday-night prediction from the United States Air Force shows
solar flux at 165 on July 14 - 15; 160 on July 16 - 18; and 155, 150,
and 135 on July 19 - 21. A prediction of 130 is shown July 22 - 24; 138
and 148 on July 25 - 26; 150 on July 27 - 29; 160 on July 30 - August
7; and 155, 145, and 135 on August 8 - 10. August 11 - 12 is 138, then
128 and 125 on August 13 - 14, and 130 on August 15 - 17.

Predicted planetary A index is 8 on July 14 - 21, then 15, 20, and 12
on July 22 - 24. Eight is predicted again on July 25 - August 2, then
12 and 10 on August 3 - 4, and 8 on August 15 - 17.

I often see news items that mention solar flares and are written as
though the world is about to end.

A few recent examples, for our collective amusement:

https://bit.ly/3yCXV3h

https://bit.ly/3RA5Bfy

https://bit.ly/3P5KakF

Sunspot numbers for July 7 - 13, 2022, were 80, 81, 89, 113, 134, 117,
and 101, with a mean of 102.1. The 10.7-centimeter flux was 121.3,
129.6, 136.9, 153, 161, 164.9, and 164.8, with a mean of 147.4.
Estimated planetary A indices were 20, 19, 6, 7, 12, 18, and 5, with a
mean of 12.4. Middle latitude A index was 15, 14, 6, 8, 10, 16, and 5,
with a mean of 10.6.
