Interest in planned satellites carrying 10 and 15 meter transponders is
growing steadily, owing in large part to the DX possibilities these
satellites will open.
The best source I know of for information about propagation from such
satellites is the Space Radio Handbook, by the late John Branigan, GM4IHJ
(SK), published by RSGB. Unfortunately, this book is out of print and may
be difficult to find.
November QST arrived several days ago. As always, I turned to the monthly
column describing the contents of QST 25, 50 and 75 years ago. Was I
surprised! In the "50 Years Ago" section, about November 1968 QST, was an
article I had written, about which I had totally forgotten in the
intervening 50 years.
It was called "Antipodal Reception of Satellite Signals," discussing what
was then known about such things and proposing an experiment to be carried
out using the 10 meter beacon to be carried on OSCAR-Australis, the name of
which was changed to Australis-OSCAR 5 after its launch in 1970.
Readers of that article will also want to read the results of the AO-5
propagation experiments, which I presented in October 1970 QST. You will
find these articles in the QST archive on ARRL's Web site, under my call
sign at the time, K2QBW. Unfortunately, copyright laws prevent my attaching
them here.
I turned out to be in very good company. Also researching in this field at
the time were Dr. Owen Garriott. W5LFL, later to be the first US ham in
space, and Dr. O. G. (Mike) Villard, Jr., W6QYT (SK), an early pioneer of
SSB. Both were then at Stanford University.

ARISS Joins NASA On-The-Air for a Special SSTV Event October 27-29
Amateur Radio On The International Space Station (ARISS) is planning
a very special Slow Scan TV event currently scheduled to start
Saturday, October 27th about 10:00 UTC. Transmissions are scheduled
to continue until around 19:30 UTC on October 29th. Helping to
support the event will be NASA?s Space, Communication and Navigation
(SCaN) Department.
The Space Communications and Navigation (SCaN) program manages NASA?s
three most important communications networks: The Space Network (SN),
Near Earth Network (NEN), and the Deep Space Network (DSN).
Just as in past ARISS SSTV commemorations, twelve images will be
downlinked, but this time with six featuring the SCaN educational
activities while the other six images will commemorate major NASA
anniversaries, ie., when NASA was established, astronauts first
landing on the moon, etc.
In addition to the fun of receiving these images, participants can
qualify for a special endorsement for the NASA On The Air (NOTA)
celebration event. To learn more about NOTA visit
https://nasaontheair.wordpress.com.
An award for receiving the images will also be available from
https://ariss.pzk.org.pl/sstv/
Once received, images can be posted and viewed at
http://www.spaceflightsoftware.com/ARISS_SSTV/index.php. The
transmissions are expected to be broadcast at the usual frequency of
145.800 MHz using the PD-120 SSTV mode.
Please note that the event is dependent on other activities,
schedules and crew responsibilities on the ISS and are subject to
change at any time.
More information will follow soon, so please continue to check for
news and the most current information on the AMSAT.org and ARISS.org
websites, the AMSAT-BB@?????.???? the ARISS Facebook at Amateur Radio

ARISS Plan Under Consideration for NASA?s Deep Space Gateway Program
Amateur Radio on the International Space Station (ARISS) Inter-
national delegates were pleased to learn last week that an ARISS plan
is under consideration by NASA?s Deep Space Gateway (DSG) program.
NASA Gateway Utilization Manager John Guidi, ex-KF4YUI, informed
those attending the annual ARISS International in-person meeting,
held in College Park, Maryland, that ARISS is the only noncommercial
entity whose ideas are under study by the program. The ARISS plan
focuses on Amateur Radio communication, including optical commun-
ication channels, as well as equipment development, team cooperation,
education, and public outreach.
?Naturally, because the NASA Deep Space Gateway program is so new and
has yet to be fleshed out, ARISS needs to follow NASA?s lead in being
open to how the DSG program flows,? ARRL ARISS-US Delegate Rosalie
White, K1STO, explained. ?ARISS?s first moves need to be loose enough
that the plan, development, and execution can go in ways that dove-
tail with what is needed.?
The Deep Space Gateway would be a small outpost orbiting the moon
that would act as a ?spaceport for human and robotic exploration to
the moon and beyond,? NASA has said. Crewed by four people, it would
provide an operational platform for further exploring the lunar
surface and a hub to deeper space destinations. NASA hopes to have
the completed Gateway in lunar orbit as early as 2024.
The ARISS-International annual meeting on October 17 ? 19 ran back to
back with the first-ever ARISS Education Summit, held October 15 ?
16. At the international sessions, ARISS delegates and team members
from around the world presented and listened to talks on all aspects
of ARISS, from operations to education to hardware ? current and
upgrades ? to future projects. The team heard the latest news on
HamTV, the Interoperable Radio System, and the antenna change-out
required by the European Space Agency?s Bartolomeo platform, and
proposed Astrobee activities, HamTV II, and Radio-Pi projects.
Astrobee is a robot that will fly around the ISS with the astronauts
to help scientists and engineers develop and test technologies for
use in zero-gravity, aid astronauts with routine chores, and offer
Houston flight controllers additional eyes and ears on the spacecraft.
Team members enjoyed viewing a live-streamed ARISS contact in
Belgium. Team members unable to travel to Maryland were able to tele-
conference into the sessions.
On hand for the earlier ARISS Education Summit were teachers from the
US and elsewhere; ARISS-US Education Committee members; STEM
educators from College Park Airport Museum; education leaders from
various NASA entities, including the Space Communications and
Navigation (SCaN) office, nearby Goddard Space Flight Center (GSFC),
and the manager of the ISS US National Laboratory ? Center for the
Advancement of Science in Space (CASIS); a group of SCaN-sponsored
mid-Atlantic teachers, and University of Maryland educators and
students. Attendees saw a demonstration of ARISS slow-scan television
(SSTV) and several ham satellite contacts. ARISS-US Education
Committee teacher Melissa Pore, KM4CZN, arrived from Virginia with
eight of her students, who talked about their ARISS-related STEM
studies.
Other committee members who were part of a panel session discussing
educator perspectives on ARISS also gave presentations on the ARISS
education proposal process and on-orbit prediction programs.
Astronaut Paul Richards, KC5ZSZ, led a discussion on space and
education; CASIS?s Dan Barstow, KA1ARD, spoke on exploring with the
ISS, and SCaN?s Jimmy Acevedo, KM4QLE, presented on kit-based
learning.

Phillipine Microsat Diwata-2 with FM transponder to Launch October 29
The Phillipine microsat Diwata-2 is expected to launch on October 29.
The satellite is scheduled to launch with GOSAT-2, a greenhouse gas
observation satellite, on a Japanese H-IIA vehicle from JAXA's
Tanegashima Space Center. The launch window is 04:08 - 04:20 UTC.
The planned orbit is sun-synchronous with an altitude of 613 km and a
Local Time of the Descending Node (LTDN) of 13:00.
Diwata-2 carries an amateur radio payload with a U/v FM transponder
and APRS digipeater capability. The uplink is 437.500 MHz and the
downlink is 145.900 MHz.

LO-94 Spacecraft Signal Decoded After Bouncing Off the Moon
Daniel Est?vez EA4GPZ / M0HXM reports decoding a JT4G amateur radio
signal from the LO-94 (DSLWP-B) spacecraft that was reflected off the
Moon.
Daniel says ?JT4G is a digital mode designed for Earth-Moon-Earth
microwave communications, so it is tolerant to high Doppler spreads.
However, the reflections of the [DSLWP-B] B0 transmitter at 435.4 MHz,
which contained the JT4G transmissions, were very weak, so I had not
attempted to decode the JT4G Moonbounce signal.?
However, by analysing a recording made on October 19, 2018 at
17:53:35 GMT he was able to decode one of the five JT4G transmissions
in the recording.

ESEO's Educational Story Continues
ESA reports the European Student Earth Orbiter (ESEO) has concluded
its test campaign. The ESEO student teams gathered in the Netherlands
October 18, 2018 for a last precious lesson before the satellite is
launched.
ESEO carries an amateur radio 1260 to 145 MHz FM transponder and a
1k2 and 4k8 BPSK telemetry beacon developed by AMSAT-UK members.
The satellite has been at ESA?s ESTEC test facilities, in the
Netherlands, where it completed the last steps of a thorough sat-
ellite test campaign which had started in August 2018 at SITAEL?s
facility in Mola di Bari, Italy.
Learning by doing has already proven an amazing experience for the
ten university student teams from different European universities who
have designed and built the instruments and several key subsystems of
the ESEO satellite.
On October 18, at a dedicated workshop, the ESEO students had the
additional chance to hear first-hand what it takes to run a satellite
test campaign ? trouble shooting included!
?In the space sector no satellite could ever be launched without a
thorough tests campaign?, said Piero Galeone, coordinating the ESA
Academy programme of which ESEO is a part. ?The reason is that ? as
perfect as your satellite design and manufacturing process can be ?
the devil always hides in the details. If there is anything to be
fixed, you want to know it and correct it before the satellite flies
on its orbit hundreds kilometres from the surface of the Earth,
beyond the reach of any engineer?s hands?.

SO-50 Distance Record Set
On Octover 24, 2018 at 13:20 UTC, Scott Richardson, N1AIA, and Jerome
LeCuyer, F4DXV, completed a 5,523 km QSO between Berwick, Maine and
Lalinde, France. This eclipses the previous record of 5,410 km set
on January 24, 2017 with a QSO between MI6GTY and UB9UTJ.
With an apogee of 704.6 km, the theoretical maximum range for SO-50
is 5,676 km. A list of currently known satellite distance records can
be found on the AMSAT website at

Does anyone have any experience comparing the Cushcraft A270-10S dualband
yagi with the MFJ 1768 yagi? I have used the Cushcraft before, and am
looking at getting a dualband yagi again. Has anyone used the MFJ yagi,
and if so, what is your opinion of it?

Nick, LORA uses chirp spread spectrum, with a signal that is ~ 125 kHz
wide (in 11 bps mode). If we have sufficient spectrum to accommodate
this, then it might be worth considering.
Sorry Bob, I must have miss-read your original posting? as I did not
realise that your proposal was for a backup command link as opposed to
an APRS user port. Considering the wide coverage area, and the need for
only a small number of backup-capable ground stations, would it be
reasonable to increase the requirements of the backup ground station to
that of a "big-gun" EME station?
If the RX chain of an FM receiver was non-linear before the last IF
filter, I'd expect that radio to be terribly susceptible to
intermodulation? (though after the RX RF has passed through the last IF
filter, then yes, linearity does not matter for FM). When I get a
chance, I'll have to do an experiment with an FM RX, an RF signal
generator and an oscilloscope connected to the 455 kHz IF...

Actually, LORA can work at 7.5 KHZ band with a spreading factor of 12. The
present rules limit the band with < 100 KHZ I believe we could get STA to go
beyond that because the spectral flux density is so low. Or team will
explore this issue with the AIRU and the FCC to see what we can experiment
with.

Hi folks,
I let my radio and SSTV program run last night. Several passes, none
super high, so my expectations were low. Also the whole downlink
frequency thing. But, as I sift through the images and static of the
night, I see about a half dozen partial pictures! Yea!
But, three of them, two from the 12:35z pass, and one from the 14:11z
pass, have an overlay from MMSSTV calling "CQ SSTV"! Were they sent
down from the ISS this way, or was someone locally rebroadcasting them
(incorrectly)? The image from the 11:02z pass seemed fine, though I
only go a part of it ("Curiosity on Mars"), as was the 15:49z pass.
Next pass, a low one, beginning in 4 minutes at 17:27z... Fingers crossed.
