New Year’s Weekend – AMSAT CW Activity Day 2018 In Memory Of G3IOR
You are cordially invited to participate in AMSAT’s second annual CW
Activity Day. It will be held from 0001 to 2400 UTC on January 1,
2018. This year’s event is dedicated to the memory of Pat Gowen,
G3IOR.
The rules are very simple: there aren’t any. Just operate CW
through any amateur radio satellite. Straight keys and “bugs” are
encouraged, but not required. The important thing is to get on the
air and have fun.

KB1LQC’s Faraday RF Blog Describes the Development of the AO-91 MPPT
Bryce Salmi, KB1LQC, writes about the development and successful
launch and deployment of the Maximum Power Point Tracker (MPPT)
designed by himself and Brent Salmi, KB1LQD. The design started
as a senior design project at the Rochester Institute of Techno-
logy.
Bryce wrote, “The story of the Fox-1 MPPT is a great example of
how amateur radio is what you want it to be. The MPPT symbolizes
the vast nature of amateur radio which spans far beyond just com-
municating over the airwaves.”
Continuing, “The Maximum Power Point Tracker has no radio inside
of it yet it is profoundly amateur radio. It’s sole purpose is to
enable scientific and ham radio payloads on-board the spacecraft.
Amateur radio is about learning, having fun, and applying techno-
logy to accomplish great things. Let’s explore this side of the
hobby!”

Fernando, NP4JV Completes Satellite Contact With All 488 CONUS Grids
Congratulations are due to Fernando, NP4JV, for completing
satellite contacts with all 488 Maidenhead grids in the contin-
ental United States. His December 28, 2017 contact with Ken,
VE3HLS in grid FN65 on XW-2B completed Fernando’s quest. Ken
was mobile on his trip to to New Brunswick. The satellite was
at 2º elevation when the contact was completed.
Fernando wrote on amsat-bb, “I would like to publicly express
my gratitude to Ken for going out of his way to help bring down
the “white whale”, and last grid needed in the 488 CONUS.”
Continuing, “I want to also thank all the satellite operators
that made this possible. All credit goes to them! Extra thanks
to all those who travelled and helped with multiple grid squares.
This has been a fun and exciting 2 years and 3 months of opera-
ting Ham Radio Satellites.”
Fernando compiled a list of the stations contacted which can
found on the archived copy of his original posting:

KA9Q AMSAT Archive Updated With Phase 3-B/Oscar-10 Documents
Phil Karn, KA9Q, wrote on amsat-bb that he has been scanning and
categorizing his stacks of paper files. He’s been working on old
AMSAT documents from the early 1980s. Phil says, “I have a good
pile of stuff on Phase 3-B/Oscar-10 that might be of interest to
the old-timers among you (and maybe of archeological interest to
others)”.
He will be placing these documents in raw form on his personal
website. There’s no index or HTML framing at the moment, but
hopefully the file names are at least slightly descriptive.
Phil advises to watch: http://www.ka9q.net/amsat/Osca

The ARRL International Grid Chase Includes Satellite Contacts
Beginning at 0000 UTC on January 1, 2018, the ARRL International
Grid Chase kicks off. The objective is simple: Work stations in
as many grid squares as possible and upload your log data to
ARRL’s Logbook of The World. Visit the ARRL Grid Chase web page
at: http://www.arrl.org/internatio
(If you are not currently registered with Logbook of The World,
this is a good reason to get started. Go to
https://lotw.arrl.org/lotw-hel
and uploading are free.)
Every new grid square contact confirmed through Logbook of The
World counts toward your monthly total, which begins when you
ring in the New Year.
Just turn on your radio and start calling “CQ Grid Chase,” or
listen for others doing the same. Make the contact, enter it
into your log, and you’re on to your next QSO.
At the end of each month, your totals on the Grid Chase leader
board will reset to zero. Fear not, though. The online scoring
system will maintain your monthly totals for a grand total at
the end of the year, when an annual summary will be released
and awards given to top finishers in various categories.
The ARRL International Grid Chase is open to all amateurs, regard-
less of location or license class. Any operating mode is eligible
as well as every band, except 60 meters. You’ll find the complete
rules at www.arrl.org/aigc2018.
Any contact can count for your Chase score; it doesn’t have to
involve an exchange of grid squares. As long as other operators
participate with Logbook of The World, you’ll get the credit
automatically when they upload their logs. This means that contest
contacts will count, as will contacts with special-event stations,
or any other on-air activity. As long as stations upload their
logs to Logbook of The World, you’re good.
Satellite contacts count. Contacts made through earthbound repeaters
do not count for the Grid Chase, but repeaters in outer space are
the exception. This includes all low-orbiting satellites that
support CW, SSB, and even FM contacts.

NASA/JPL is Testing Combined Deployable Solar Cell & Antenna Panel
After cargo ship Cygnus OA-8E (SS Gene Cernan) was unberthed from the
Unity module of the ISS on December 5 it continued in orbit to release
cubesats and perform additional testing. On December 6 Cygnus raised
its orbit from 402 x 407 km to 447 x 456 km. It then deployed 14 cube-
sats on December 6 and 7. Cygnus was deorbited on December 18, with
entry over the South Pacific.
One of the cubesats deployed from Cygnus was the NASA/JPL Integrated
Solar Array and Reflectarray Antenna (ISARA) mission to demonstrate a
reflectarray antenna that increases downlink data rates for CubeSats
from the existing baseline rate of 9.6 kilobits per second (kbps) to
more than 100 megabits per second (Mbps).
The reflectarray antenna consists of three panels, electrically tied
together through hinges, which have an array of printed circuit board
patches on them. The size of the patches are adjusted so that the phase
of the reflected feed illumination collimates the radiation in much
the same way a parabolic dish reflector would. Unlike a parabolic
dish, however, the reflectarray panels are flat, which enables them
to be folded down against the CubeSat. On the opposite side of the
printed reflectarray antenna, solar cells have been added.

Philippines’ Diwata-2 Microsat to Include Amateur Radio Transponder
The IARU frequency coordination pages show that the Diwata-2 team
have applied for amateur radio frequency coordination:
http://www.amsatuk.me.uk/iaru/
Diwata-2 is the Philippines’ second microsatellite designed
and developed by Filipino scientists and engineers under
the PHL-Microsat Program. They describe their program at:
http://phl-microsat.upd.edu.ph
Diwata-2 is a 50x50x50 cm microsatellite with estimated mass
of 50kg. It features two deployable systems – solar array
panels and amateur radio antennas.
Diwata-2 will carry optical payloads that will support the
following objectives:
+ Determining the extent of damages from disasters
+ Monitoring natural and cultural heritage sites
+ Monitoring changes in vegetation
+ Observing cloud patterns and weather disturbances
These paylaods will use non-amateur S and X Band frequencies.
In addition to these optical payloads, Diwata-2 will also
carry an amateur radio unit. This payload is intended to pro-
mote awareness and interest in amateur radios and satellite
technology in the country. It is also intends to provide an
alternative means of communication at times of disasters and
emergencies.
Diwata-2 is proposing a U/V FM transponder with APRS and CW
beacon. Planning a launch from Tanegashima, Japan into a 613km
polar orbit in Q2 2018.

IARU Coordination Completed for DreamSat for ISS Deployment in 2019
The Dream Satellite Project plans to develop and deploy a 1U cube-
sat from the ISS in 2019. The structure and bus system of this sat-
ellite consists of the OPUSAT-Kit, which is developed based on Osaka
Prefecture University’s OPUSAT CubeSat, manufactured by NISSIN Co.,
Ltd.
The Dream Satellite Project will develop the mission system:
+ Provide amateur radio mailbox service
+ Provide QSL service
+ Store and forward message operations
A downlink at 145.860 MHz and UHF uplink have been coordinated.
DreamSat has not yet announced their UHF uplink frequency. Data
