Mark Johns, KØJM, Appointed Editor-in-Chief AMSAT News Service

Robert Bankston, KE4AL, VP-User Services announced the appointment of
Mark D. Johns, KØJM, as Editor-in-Chief of the AMSAT News Service.

Johns, currently serving as a rotating ANS weekly editor, steps up to
replace EMike McCardel, AA8EM, who is facing a long recovery follow-
ing a serious injury while clearing storm damage at his home in early
August.

Mark Johns is Professor Emeritus, Journalism and Communication Stud-
ies, of Luther College, Decorah, Iowa, but now resides in the Minne-
apolis, Minn. area. He is a life member of ARRL and AMSAT, holds a
DXCC Satelite certificate, and is a member of the Minnesota Wireless
Association and the Twin Cities DX Association (TCDXA). Mark is also
on the editorial staff of the Gray Line Report, the newsletter of
the TCDXA.

Mark grew up in Des Moines, Iowa and was first licensed there in 1967
as WNØRGV. Through college, grad school, and early career he operated
from various QTHs in Nebraska, Minnesota, and Iowa as WAØRGV, and
later as KØMDJ. He began operating satellites in the early 1980s.
After living in Cedar Falls, Iowa for 26 years, he took a one year
work assignment in Nottingham, UK during 2011-12 and operated there
as MØGZO. From fall of 2012 until spring of 2017 his QTH was Decorah,
but he also operated in Malta as 9H3DJ for half of 2016 while on an-
other work assignment. His current callsign was granted in 2018, and
he is primarily active on the linear transponder satellites.

Emergency Traffic Relayed over AO-92 Satellite

On August 27, 2019, Clayton, W5PFG, and his father Jack, AC5DI, were
traversing the Chihuahuan Desert in Big Bend National Park, Texas,
USA, when their vehicle became stuck in mud from recent monsoon rains.

Being stuck up to the axles, they were unable to self-recover from
the situation, requiring assistance from Park Rangers. August temper-
atures in this desert reach upwards of 110-115 degrees Fahrenheit.
There is no mobile phone coverage outside park headquarters.

Clayton made contact via AMSAT satellite AO-92 with Kevin, KK4YEL,
in Florida. During the satellite pass, stations stood by while Clayton
relayed emergency traffic to Kevin. This information included details
about the situation including precise latitude and longitude, the
phone number for Big Bend National Park, vehicle description, and wel-
fare of the party.

Other stations listening to the pass including Brian, KG5GJT, contacted
the park headquarters. Within two hours, Park Rangers arrived on scene
and recovered the stuck vehicle. No person was injured, and no equipment
was damaged.

Clayton and Jack were traveling to DL88jx, a maidenhead grid square high-
ly sought after by many ARRL VUCC members. Clayton had previously made
two successful trips to DL88jx. Both Clayton and Jack are very grateful
to Kevin, KK4YEL, the responsiveness of the amateur radio community,
and to the Park Rangers and staff of Big Bend National Park.

Incident discussion via Twitter quickly provided recordings of the
AO-92 satellite traffic:

University of Tsukuba YUI Satellite Project D-ATV User Survey

Takehiro Okamoto, student leader of University of Tsukuba YUI project
in Japan, reports his team is developing a 2U cubesat planned to fea-
ture real-time video transmission from space as the main mission. This
project, wants the general public to view and use the images, and are
soliciting user opinions.

They plan to downlink D-ATV from the 2U CubeSat, similar to HamTV
from the ISS. Complete the survey posted at:

   bridge via K6DUE located in Maryland. The ISS callsign is pre-
   sently scheduled to be NA1SS. The scheduled astronaut is Drew
   Morgan KI5AAA. Listen on 145.800 for east coast North American
   stations.

+ Tuesday, September 3, 2019 16:05 UTC

AMSAT and ARISS are currently supporting a FundRazr campaign to raise
$150,000 for critical radio infrastructure upgrades on ISS. These up-
grades are necessary to enable students to continue to talk to astro-
nauts in space via Amateur Radio. We have reached a great milestone
with $24,130 raised or about 16% towards our goal. This would not have
been possible without your outstanding generosity!! For more informa-

AMSAT SA Dual Band Yagi Now Available for Export

AMSAT South Africa (AMSAT SA) has developed a dual-band Yagi VHF/UHF
antenna for satellite operation. The antenna has a 50-ohm designed
driver. The Yagi has a unique element called a 'Open Sleeve' which
is a director very close to the driven element. The driven element
is sized for 2M.  When operating on 70cm the 'Open Sleeve' acts as
part of the driven element on 70cm (Third harmonic of 2M).

The original concept was developed in 1946 by Dr J T Bolljahn of the
Stanford Research institute but was not introduced into amateur radio
until the 1950s. The AMSAT SA version is based on a design by DK7ZB
with modifications by WB5CXC.

Until recently this antenna was available only in South Africa. Fol-
lowing requests from many amateurs outside South Africa AMSAT SA can
offer the Yagi for export if ordered in a batch of 6, at R950 each
(approx US $65), total for a batch of 6 is R5700. (approx US $ 390)
to countries in the European Union and the USA. For Australia and New
Zealand R1000 per unit in a batch of 6 total RR6000. Pricing for
other countries on request.

German CEPT Response States Sharing of 144-146 MHz Not Realistic

Update: The ARRL reported on August 30, 2019 -
144 – 146 MHz Removed from French Proposal for Additional Aero-
nautical Applications: https://tinyurl.com/ANS-244-ARRL-2M-Removed

The latest development regarding the proposal to share 144-146 MHz
comes from Germany.

They state, "Germany does not support the inclusion of the 144-146 MHz
primary allocated to the amateur service/amateur satellite service in
the proposed WRC-23 agenda item regarding a possible new allocation to
the aeronautical mobile service (AMS) for non-safety applications.

Consequently, Germany cannot determine a single realistic sharing scen-
ario, not leading to serious mutual interference on both sides and not
seriously degrading the use of the 144-146 MHz band."

CAMSAT Applies for IARU Coordination for Four V/U Transponder Satellites

The Chinese Amateur Satellite Group (CAMSAT) has applied for frequency
coordination for four small satellites - CAS-8A, CAS-8B, CAS-8C, and
CAS-8D. The CAS-8 satellites are a Student Small Satellites project
initiated by the Asia-Pacific Space Cooperation Organization (APSCO),
which is headquartered in Beijing China. APSCO was inaugurated in 2008
as an inter-governmental organization. including Bangladesh, China,
Mongolia, Pakistan, Peru, Thailand, Turkey and Indonesia.

The project consists of four satellites, including a pilot microsatel-
lite CAS-8A for technical verification and a primary microsatellite
CAS-8B, two 3U cube satellites CAS-8C and CAS-8D. CAS-8A is scheduled
to be launched by the end of 2020, and the CAS-8B, CAS-8C, CAS-8D sat-
ellites are scheduled to be launched at the end of 2021 ON the same
launch.

The CAS-8 satellites project is supported by the Chinese government. The
project is led by Beihang University, which is China's most outstanding
university in aerospace. tHE Chinese Amateur Satellite Group (CAMSAT)
cooperates with Beihang University to bring amateur radio into the pro-
ject.

the CAS-8 satellites will realize the synergy between the eight countries
of APSCO to build an amateur radio alliance through space, adding new
science popularization tools to young students in APSCO member countries
for self-training, inter-communication and technical investigations, and
also providing a new satellite platform for amateur radio enthusiasts
around the world.

CAMSAT 8A - 30kg Microsat. V/U transponder, UHF CW and AX25 4k8/9k6
             GMSK telemetry beacons and S Band 192kbps GMSK Image and
             4k8/9k6 GMSK telemetry downlinks. Planning a launch from
             Jiuquan in Oct 2020 into a 600km SSO.

CAMSAT 8B - 30kg Microsat. V/U transponder, UHF CW and AX25 4k8/9k6
             GMSK telemetry beacons and S Band 192kbps GMSK Image and
             4k8/9k6 GMSK telemetry downlinks. Planning a launch from
             Jiuquan in Oct 2021 into a 600km SSO.

CAMSAT 8C - 3U CubeSat. V/U linear transponder, UHF CW and AX25 4k8/9k6
             GMSK telemetry downlinks and S Band AX25 4k8/9k6 GMSK inter
             satellite links. Planning a launch from Jiuqhan in Oct 20121
             into a 600km SSO.
