Wow, Bob. My condolences on your blood pressure!
In the spirit of the original mission of the founders of the ARRL to educate
and encourage fellow hams, I have also done what I can to teach and
encourage hams to start working linear satellites, to pay forward the
assistance I recently received myself from many on this list to start
working linear satellites. You can learn much and have a lot of fun on FM
birds, frustrations notwithstanding, but nothing is more satisfying than
learning to operate two SSB radios to work a low elevation AO-7 or FO-29
pass in a short window of time, culminating in a successful contact with a
very distant and exotic DX location not possible to reach via FM. As many
here have pointed out, there?s plenty of bandwidth on linear birds, and I
have often heard long ragchews about rainfall amounts and shack equipment
modifications occurring at the same time in the linear passband along with
DX chasers exchanging grids and newbies calling CQ!
The curmudgeon only serves to highlight the original point of encouraging
more folks, especially the next generation of hams, to learn, experiment,
and work linear birds. I?ll consider my own mission complete when the
curmudgeon can tune through the passband on ?his linear sats" to hear
conversations of millennials and younger from rare ?strips of dirt? not just
exchanging grids and having fun, but also discussing the best artisanal
avocado toast, the melancholy angst of unrequited love, debates over the
best new wave death metal guitarist, and environmentally-friendly cloth
diapering techniques to best protect the bottoms of the next generation of
hams.
73!

Hi Zack,
I honestly wish I had a LimeSDR Mini.? I learned about it just about
a month ago.? Don't have the funds at the moment to divert to getting
one.? I'd almost be willing to sell my SDRPlay RSP2 in order to get
one.? In the meantime, I'm trying to cobble something together to be
able to work the linear birds.
I understand that SSB and CW have been the 'mandated' modes used to
work the linear birds for a long time.? SSB use appears to be the
predominant mode of operation. I'm still not hearing, though, any real
arguments against the use of DSB as a means to drastically lowering the
barfor transmit to the linear satellites.DSB could be implemented with
relatively simple analog hardware that would avoid the complexity of
DSP development and I/Q modulation balancing.

Answer from Chris: It does automatically reload the keps every so often.
He did not remember at the time how often, but you should not need to stop

ARISS-US Program Education Proposal Deadline is April 30, 2018
ARISS News Release?? ?No. 18-03

International Space Station Astronauts are Calling CQ Students
ARISS-US program education proposal deadline is April 30, 2018.
March 15, 2018:? The Amateur Radio on the International Space
Station (ARISS) program is seeking proposals from US schools,
museums, science centers and community youth organizations
(working individually or together) to host radio contacts with
an orbiting crew member aboard the International Space Station
(ISS) between January 1 and June 30, 2019.
Each year, ARISS provides tens of thousands of students with
opportunities to learn about space technologies and communications
through the exploration of Amateur Radio. The program provides
learning opportunities by connecting students to astronauts
aboard the International Space Station (ISS) through a partner-
ship between NASA, the Radio Amateur Satellite Corporation, the
American Radio Relay League, and other Amateur Radio organizations
and worldwide space agencies. The program?s goal is to inspire
students to pursue interests and careers in science, technology,
engineering and mathematics (STEM) and Amateur Radio. A ham
recently said, ?ARISS shows how Amateur Radio is the most unique
hobby/service there is.?
Educators overwhelmingly report that student participation in the
ARISS program stimulates interest in STEM subjects and in STEM
careers. One educator wrote, ?It exceeded our expectations--it
created a great interest in both amateur radio and in space
exploration. Our kids are completely inspired!? Ninety-two percent
of educators who have participated in the program have indicated
that ARISS provided ideas for encouraging student exploration
and participation. An educator even joined the ham ranks, saying,
?This chance for our school?s ARISS contact helped me see the
great value of the ham world. I just passed my Technician License
this weekend and have already signed up to take a General class.?
ARISS is looking for organizations that will draw large numbers
of participants and integrate the contact into a well-developed,
exciting education plan. Students can learn about satellite
communications, wireless technology, science research conducted
on the ISS, radio science, and any related STEM subject. Students
learn to use Amateur Radio to talk directly to an astronaut and
ask their STEM-related questions. ARISS will help educational
organizations locate Amateur Radio groups who can assist with
equipment for this once-in-a-lifetime opportunity for students.
The proposal deadline for 2019 contacts is April 30, 2018. Proposal
webinars for guidance and getting questions answers will be offered
March 29, 2018, at 7 p.m. EDT and April 16, 2018, at 4 p.m. EDT.
Advance registration is necessary. To sign up, go to
https://ariss-proposal-webinar-spring-2018.eventbrite.com

About ARISS
Amateur Radio on the International Space Station (ARISS) is a
cooperative venture of international amateur radio societies and
the space agencies that support the International Space Station
(ISS). In the United States, sponsors are the Radio Amateur
Satellite Corporation (AMSAT), the American Radio Relay League
(ARRL), the Center for the Advancement of Science in space (CASIS)
and National Aeronautics and Space Administration (NASA). The
primary goal of ARISS is to promote exploration of science, tech-
nology, engineering, and mathematics (STEM) topics by organizing
scheduled contacts via amateur radio between crew members aboard
the ISS and students in classrooms or public forms. Before and
during these radio contacts, students, educators, parents, and
communities learn about space, space technologies, and amateur
radio. For more information, see www.ariss.org.

AO-92 operations are scheduled among the U/v FM repeater, L-Band
Downshifter, Virginia Tech Camera, and the University of Iowa?s
High Energy Radiation CubeSat Instrument (HERCI). Please keep
the uplink clear during passes with scheduled mode changes.
For the week of 18-24 Mar 2018, the following mode changes are
scheduled:
+ 18 March at approximately 1500 UTC we will enable the L band
? uplink for ~24 hours
+ 22 March at approximately 1345 we will enable the VT camera and
? high-speed data for ~40 minutes. This is a Caribbean and South
? America pass. Please be ready to copy high-speed data with FoxTelem,
? and keep the uplink clear at 1345UTC.

It?s that time of year again; summer and Field Day! Each year the
American Radio Relay League (ARRL) sponsors Field Day as a ?picnic,
a campout, practice for emergencies, an informal contest and, most
of all, FUN!?
The event takes place during a 23-hour period on the fourth weekend
of June. For 2018 the event takes place during a 27-hour period from
1800 UTC on Saturday, June 23, 2018 through 2100 UTC on Sunday,
June 24, 2018.
Those who set up prior to 1800 UTC on June 23 can operate only 24
hours. The Radio Amateur Satellite Corporation (AMSAT) promotes
its own version of Field Day for operation via the amateur sat-
ellites, held concurrently with the ARRL event.
This year should be easier than many years since we have more than
10 transponders and repeaters available. Users should check the
AMSAT status page at http://www.amsat.org/status/ and the pages
at http://www.amsat.org/?page_id=177 for what is available in
the weeks leading up to field day.
To reduce the amount of time to research each satellite, see the
current FM satellite table at http://www.amsat.org/?page_id=5012
and the current linear satellite table at
http://www.amsat.org/?page_id=5033
If you are considering ONLY the FM voice satellites, there are
SO-50, AO-85, AO-91, AO-92 and possibly PicSat. It might be easier
this year to make that one FM contact for the ARRL bonus points
with so many FM birds. The congestion on FM LEO satellites is
always so intense that we must continue to limit their use to
one-QSO-per-FM-satellite. This includes the International Space
Station. You will be allowed one QSO if the ISS is operating Voice.
The full set of rules are posted at:

HuskySat-1 Applies for IARU Coordination for Linear V/U Transponder
The IARU Frequency Coordination pages show that the Husky Satellite
Lab at the University of Washington applied for frequencies on March 7
for HuskySat-1, a 3U CubeSat with propulsion capability.
Launch is planned for a high inclination LEO late 2018 on the ELaNA
XXIV mission. HuskySat-1 will become the first amateur satellite
from Washington state.
HuskySat-1 will demonstrate the capabilities of new technologies being
developed at the University of Washington and expand the capabilities
of CubeSats as a whole. In particular, a high-thrust pulsed plasma
thruster (PPT), and high-gain communications system will form the core
technology suite on board the satellite.
HuskySat-1 will carry AMSAT's 30 kHz wide V/u linear transponder for
amateur radio SSB/CW communications. The transponder is the same design
as the transponder being flown on RadFXSat-2/Fox-1E in 2018 including
the 1k2 BPSK telemetry channel. HuskySat-1 will also transmit BPSK
telemetry at 1 Mbps in the 24 GHz band.
In order to utilize the transponder and telemetry beacon, equipment
suitable for other linear transponder satellites such as FO-29 and AO-73
will be needed. Estimates are that a few watts into a small beam
should be adequate, with a small beam with a low noise preamp serving
for reception.
Additional details have been posted at:

window with 0.4 degrees for EB1AO (contact was made at 0.1 degree
elevation) and 2 degrees for W0DHB. Jose operated portable on
a hilltop with an IC-910 and Arrow Antenna. To date he has 34
states via satellite.
PS8ET (GI84) worked CU2ZG (HM77) for a 5096 KM contact wia
AO-91 on March 12.
Mikey, K7ULS reported working FG8OJ and PJ2/HB9WDF via FO-29
on March 13.
Now, a report on quantity vs distance ... congratulations to
Michael, K9EI for his completion of Satellite Worked All States.
He commented on Twitter, "Please let me say thank you to everyone
who helped me finally achieve my first WAS. I became a ham in 1977,
but never was involved enough to accomplish WAS. I am even more
satisfied that I was able to do it first on satellites among so
many friends. You?ve all been fantastic."

Melbourne University Student Space Program Update
Gabriel, VK3EXO, provided an update to the Wireless Institute of
Australia regarding the Melbourne University? Student Space Program.
From the RF perspective project personnel have successfully trans-
mitted packets between the ground station and the satellite radio.
They have interfaced the satellite radio with the flight computer
and the satellite antenna has been deployed.
The ACMA recently approved the frequency allocation request and will
be taking the application to the ITU on behalf of the project team.
This is a huge achievement, particularly for an entirely student led
organization.
A major milestone has been passed with power-up test of everything
to be included in the satellite all laid out on a flat surface called
a FlatSat. The next step is to perform extensive software and hard-
ware testing. The testing will be performed over the next few weeks.
The Mission Operations website development is going well and the team
is on track for launch at the end of this year / early next year.

AMSAT Member Perry F. Crabill, W3HQX Silent Key
This week Larry Wright, W8ANT, reported the sad news that Perry F.
Crabill, W3HQX, member of AMSAT, born in 1920, formerly of Washington,
DC and suburban Maryland and until his passing of Winchester Virginia,
is now a Silent Key at age 97.
Perry was first licensed as W3HQX in "19ought38" as he was wont to
say, worked for C&P telephone for many years, served in the US Navy
in World War Two as a radio technician (passing the difficult Eddy
test,) and was active for almost 70 years in a variety of amateur radio
activities. Known affectionately by the 147.300 repeater's "Question
Of the Day" group as "The Professor", Perry had a wide range of
on-the-air acquaintances.
A memorial service and celebration of his life was held on Saturday,
March 24 in Winchester, VA.

China's DSLWP-A1/A2 Satellites to Transmit Amateur Radio Data from the Moon
China is planning to launch the Chang?e 4 lander and rover which is
slated to land on the far side of the moon in December. The lander
configuration will use a relay satellite for a control and data
link with Earth.
Also aboard this flight will be a pair of microsatellites, DSLWP-A1
and DSLWP-A2, which will test low-frequency radio astronomy and
space-based interferometry. These two lunar orbiting satellites
developed by students at the Harbin Institute of Technology will
include educational and amateur radio payloads (but not a trans-
ponder).
The Amateur Radio payload on DSLWP-A1 will provide a telecommand
uplink and a telemetry and digital image downlink. Radio amateurs
will be able to transmit commands that allow them to send commands
to take and download an image. The IARU has coordinated downlinks
on 435.425 MHz and 436.425 MHz for A1.
Downlinks have been coordinated for A2 are 435.400 MHz and 436.400
MHz using 10K0F1DCN or 10K0F1DEN (10-kHz wide FM single-channel
data) 250 bps GMSK with concatenated codes or JT65B.
A1 and A2 will be deployed into a 200 ? 9,000 kilometer lunar
orbit. The 50 ? 50 ? 40 centimeter spacecrafts each? weigh about
45 kilograms and are three-axis stabilized. Two linear polarization
antennas? are mounted along and normal to the flight direction.
The satellites will use the moon to shield them from radio emissions
from Earth for the long wavelength space-based interferometry experi-
ments.
The launch is anticipated for May or June on a CZ-4C vehicle, putting
the satellites? deployment about 6 months ahead of the launch of the
Chang?e 4 lander and rover.
