I don't mind the "One and Done" on the FM birds one bit. They're crowded
enough during "normal" times, and a complete ZOO on Field Day. The only
time I try and work an FM bird on Field Day is when they're way to the
West, with most of the footprint over the Pacific. I get my one FM
contact, and then back to the linear birds.
I don't think putting an official mega-station on an FM bird to dole out
contacts would work. You'd still have insane uplink contention, and
people calling, calling, calling anyway. Perhaps the only way to kill
the crud on Field Day is drop the 100 point bonus entirely, and just let
satellite contacts count as regular contacts as we're discussing.
I agree 100% that each bird should count as a separate "band", along
with allowing different modes on each bird to be counted as separate
contacts, just like they are on HF.
SSB, CW, and digital should get you three points per bird, just like it
does on 20 Meters.
But then who are we to suggest the league change their rules......
Oh, well....

I've thought put w1aw and k6kph on the FM birds with some
serious punch and have them hand out contacts on the FM birds. And have them
be the only contacts that count...Or drop the 100 point bonus eliminating a
lot of folks without satellite experience.

For the purpose of Field Day, LilacSat-1 or LO-09 will be considered a
digital satellite and not a single channel FM satellite. The reasoning is
that an FM single channel satellite has an FM voice modulated signal going
up and an FM voice modulated signal coming down. With LO-90, there is an FM
voice modulated signal going up however, you must have separate equipment to
demodulate the digital signal. This will also score three points for
each digital contact that you make. Sorry for the late rule, LO-90 is a very
new satellite and mode.

India Launches 40th PSLV With 31 Satellites On-board
An Indian mapping satellite and 30 other payloads vaulted into space Friday
aboard a Polar Satellite Launch Vehicle, arriving in an on-the-mark
orbit more
than 300 miles above Earth.
Launching on its 40th flight, the PSLV rocketed away from the Satish Dhawan
Space Center, a facility nestled on Sriharikota Island on India?s east
coast, at
0359 GMT Friday (11:59 p.m. EDT Thursday). The 144-foot-tall (44-meter)
launcher
thundered into a mostly sunny sky over the launch base, where liftoff
occurred
at 9:29 a.m. local time
The 1,570-pound (712-kilogram) Cartosat 2E satellite was the primary
passenger
on Friday?s launch, joining a fleet of Earth-imaging platforms built to
feed
observations of cities, crops, natural disasters and other targets to
Indian
civil and military authorities.
Cartosat 2E radioed ground controllers moments after separation from the
PSLV?s
fourth stage, and engineers confirmed it unfurled its solar panels as
planned.
The PSLV launch team confirmed the upper stage released another Indian
satellite
? NIUSAT ? a few seconds after Cartosat 2E. Designed for agricultural
monitoring, NIUSAT is suitcase-sized satellite weighing about 33 pounds (15
kilograms) developed by students at Noorul Islam University in India?s
Tamil
Nadu state.
Fifteen other satellites launched Friday also include amateur frequency
downlinks:
Max Valier Satellite 145.860 MHz
Venta 1 437.325 MHz
Pegasus 436.670 MHz
NUDTSat 436.270 MHz
VZLUSAT 1 437.240 MHz

ARISS SSTV Commemorative Activity
Special Slow Scan Television (SSTV) transmissions are expected to be
made from
the International Space Station on 145.800 MHz FM around the weekend of
July 15.
In commemoration of their 20th anniversary, the ARISS team is planning to
transmit a set of 12 SSTV images that capture the accomplishments of
ARISS over
that time.
The ARISS SSTV Blog says:
While still to be scheduled, we anticipate the SSTV operation to occur
around
the weekend of July 15. We are planning for at least a 2 day operation,
but are
working for a potential longer operation. Note that all of this
tentative and
may change based on crew scheduling and ISS operations.
Starting with our first meeting in November 1996, our joint operations
on Mir,
becoming the first operational payload on ISS in November 2000 to our
1103rd
school contact (so far), ARISS? accomplishments have been tremendous. We
have
touched the lives of many and inspired and educated countless students
to pursue
science, technology, engineering and math careers.
Please stay tuned as more details on our SSTV event will be communicated
in the
coming weeks. Please spread the word. And think about how you can get
students
in your area involved in capturing these images. We would love to hear
your
stories on how that goes.

LilacSat-1 Designated LilacSat-OSCAR 90
OSCAR Number Administrator Bill Tynan, W3XO, has announced that,
pursuant to a request submitted to the AMSAT Board of Directors, the
LilacSat-1 satellite has been assigned the designation LilacSat-OSCAR
90, or LO-90.
LilacSat-OSCAR 90 was designed and constructed by the Harbin Institute
of Technology in Harbin, China as part of the QB50 project to study
the lower thermosphere. It was carried aboard an Orbital-ATK Cygnus
cargo ship, which was launched to the International Space Station on
April 18, 2017, and deployed from the ISS on May 25, 2017.
LO-90 carries a voice transponder with a 145 MHz FM uplink and a 435
MHz digital voice downlink using the Codec2 open source voice codec as
well as a camera open for activation by amateur radio operators
worldwide.
More information about the satellite can be found
http://lilacsat.hit.edu.cn/?page_id=594. A guide for receiving the
downlink prepared by Adam Whitney, K0FFY, can be found at
http://adamwhitney.net/working-lilacsat-1/.
Since the launch of the first amateur radio satellite, OSCAR 1 in
1961, it has been traditional for amateur radio satellites to carry
the name OSCAR, for ?Orbiting Satellite Carrying Amateur Radio?.
AMSAT, which administers the numbering of OSCAR satellites at the
request of the Project OSCAR organization, encourages all
builders/owners of amateur radio satellites that meet the requirements
listed at http://www.amsat.org/?page_id=2478 to apply for an OSCAR
designation.

Amateurs Recover I-Inspire-2 Satellite
I-Inspire-2 is a 20 x 10 x 10cm CubeSat built by the University of
Sydney in
collaboration with the Australian National University and the University
of New
South Wales (Sydney)
WIA News reports:
On board the tiny spacecraft is an experiment, part of the QB50 project,
designed to ?explore the lower thermosphere, for re-entry research and
in-orbit
demonstration of technologies and miniaturised sensors?, as reported in
earlier
editions of the WIA broadcast.
Its operational frequency was coordinated by IARU to be in the satellite
segment
of the 70cm amateur band.
It was placed in orbit from the International Space Station in late May.
The
deployment was successful; however there were no signs of life when the
ground
stations started looking for it. The engineering group quickly tested
various
scenarios on the engineering model only to come to the conclusion that,
due to
the extended delay in the deployment, the satellite?s battery was likely
to be
depleted and the satellite was trapped in an endless loop, trying to
deploy its
antenna.
The engineering group suggested that the satellite is still listening
albeit
with its antennas in the stowed position. This meant that the satellite
command
receiver might have difficulty receiving any signals from ground control
stations. A set of commands were devised which, if received, would
instruct the
satellite to wait until the battery is charged before attempting to
deploy its
antenna. Both UNSW and ANU ground stations transmitted the recovery
command to
the satellite; however after a week or so of no success it was decided
that more
transmitter power was required to overcome the lack of receiver sensitivity
caused by the still stowed antenna. A request for assistance was passed
to EME
operators around the world and many responses were received.
The greatest hope for a successful recovery was thought to be PI 9 CAM
using
high power and a 25 m dish, normally used for radio astronomy but also
EME. They
were scheduled to transmit on the weekend of June 10-11.
On Sunday June 11, during the morning pass, Rob VK1KW reported a strong
signal
every 30 seconds on I-Inspire-2?s frequency. Dimitris VK1SV who is part
of the
ANU team, verified reception from home around midnight. The following
morning
Dimitris drove to the ANU ground station and was able to send commands
to the
satellite for the first time since it was deployed. Many other radio
amateurs
around the world also reported reception of the beacon. The satellite
had come
back to life!
This is a wonderful example of successful collaboration between radio
amateurs
and the academic community. If a frequency outside the radio amateur
band had
been used, it is doubtful that the satellite would have been brought
back to
life.
The crew of I-Inspire-2 wishes to thank all radio amateurs involved and is
looking forward to a successful collection of data for the scientific
experiment!

New Zealand?s KiwiSAT Update
Yes, we?re going into space and you can be part of it!
AMSAT_ZL has reached a staging point in the development of their satellite
project, KiwiSAT. We?re ready to go, ready to get up there!
The KiwiSAT Team has produced a fine unit ready to launch. Then came a
set-back.
Our critically important Leader of the KiwiSAT Engineering Team, Fred
Kennedy
ZL1BYP, was struck down and driven to endure many months of medical
procedures.
This has have left him unable to continue his important work. It?s time for
renewal.
Over time the support team has aged, drifting from their positions of
youth and
ability. Much has been achieved but all to no avail if KiwiSAT sits on a
shelf.
Can you help?
AMSAT-ZL is looking both to its members and to the general New Zealand
amateur
radio population for a coordinator to join the team and lead the project
through
this final stage. We?re making history. We?re going into space!
We need a volunteer ?Orbit Insertion Team? consisting of a Launch
Co-ordinator
and as many assistants as he/she requires to undertake the task of
securing a
launch for KiwiSAT. This new team will also take over Fred Kennedy?s
leadership
responsibilities. In parallel, the established
KiwiSAT engineering team will continue their involvement, giving support
along
the way.
Much of the new team?s work will be organisational rather than hands-on
engineering. Involved is arranging final environmental testing of KiwiSAT,
identifying and negotiating a launch, attending the launch and attending to
funding for this final phase. Basic planning is complete, we need action.
Other tasks will undoubtedly be crop up however it is envisaged that the
current
team will ensure the preparation of KiwiSAT to full flight status is
completed.
Offers need to be received by 30 June 2017. The AMSAT-ZL Committee will
then
appoint a team and leader. Offers can be advised to the AMSAT-ZL
Secretary, 894
Ponga Road, RD 4, Auckland 2584 or by Email to iana@xxxxx.xxx.xx or to
myself
tdcarrell@xxxxx.xxx. Email either of us for more details.
Financial assistance is available to enable the successful applicant to
meet for
a briefing with Fred in Auckland, July this year.
Thank you,
Terry, ZL3QL

I noticed something odd today while operating satellites for FD. I usually
get anyone who wants in the audience involved, I have someone log, I make
the contact and run the s/w and radio, I also pass the mic to anyone who
wants to make a sat contact, and another person will point the antenna. We
find a north marker and I give that person my cell phone as a antenna
pointing aid. Anyway on my cell phone running GoSatWatch an iPhone app that
there was a AO-73 pass at 9:28 EST. The pass was a nice 77 degree's. I
walked to my sat setup with the group and turned on the TS2000 and my
Laptop, and I couldn't find the pass on my laptop. To make a longer story
short after looking at all data the 9:28 on the iPhone pass was a phantom
pass. I noticed it was only 38 minutes after the last AO-73 pass. I still
can see it after doing a kep update in my phone. Anyone else see this?
Anyone know why this might happen? I've never seen it before.

Sry about the subject error...
I noticed something odd today while operating satellites for FD. I usually
get anyone who wants in the audience involved, I have someone log, I make
the contact and run the s/w and radio, I also pass the mic to anyone who
wants to make a sat contact, and another person will point the antenna. We
find a north marker and I give that person my cell phone as a antenna
pointing aid. Anyway on my cell phone running GoSatWatch an iPhone app that
there was a AO-73 pass at 9:28 EST. The pass was a nice 77 degree's. I
walked to my sat setup with the group and turned on the TS2000 and my
Laptop, and I couldn't find the pass on my laptop. To make a longer story
short after looking at all data the 9:28 on the iPhone pass was a phantom
pass. I noticed it was only 38 minutes after the last AO-73 pass. I still
can see it after doing a kep update in my phone. Anyone else see this?
Anyone know why this might happen? I've never seen it before.

Thanks for the links to two articles. They were both interesting, and the
33-year-old magazine issue was also fascinating in its entirety.
Unfortunately, neither one was sufficiently detailed to allow one to build
a water-propulsion system by "following a blueprint". I wonder if the
Cornell Cube Quest Challenge (CQC) submission is in the public domain and
accessible through the Internet? That would also make for fascinating
reading.
I guess I have an ulterior motive, as I am a member of the AMSAT ASCENT
program who is struggling to make some meaningful contributions to the
Ragnarok/AMSAT entry in the CQC. Our satellite had been planning to use a
donated thruster but the donation promise was just rescinded because the
vendor found an earlier flight on which they could put their design to the
test to get flight history that would help them sell copies of the thruster
to future customers.
In case anyone is wondering why we still care, since our submission didn't
win one of the top three positions with a guaranteed launch as part of the
CQC competition, we are still hoping to get an affordable launch by other
means, and get into a HEO if not into a full lunar orbit for the CQC
competition. And if one of the top 3 CQC winners is unable to get their
satellite ready in time and we have a viable satellite ready to go, we
could still get a ride on the CQC launch. And in any case, we want to
continue to innovate for whatever satellite opportunities evolve in the
future.

I?ve operated my home satellite station each of the past few Field Day?s but
2017 out shined them all. Each pass was nearly filled with stations calling
?CQ Field Day.? It was music to my ears although cacophonous at times.
Even though I was limited by family events, I managed to log 33 Satellite
Field Day contacts Saturday and a few more today when time permitted. Even
AO-7 stayed up and gave me quite a few contacts on Saturday.
I think my favorite pass was on XW-2A 25 June 2017 around 0130Z. It brought
that old hymn to mind with a new title ?Let?s all gather at the center.? See
the following link for the waterfall spectrum.

As expected, the FM satellites were overloaded with traffic but the current
crop of linear satellites more than made up for it.
Looking back at a great 2017 and forward to an even better 2018.
Congratulations AMSAT!
