Message to US Educators
Amateur Radio on the International Space Station
Contact Opportunity
Call for Proposals
Proposal Window February 15 ? April 15, 2017
The Amateur Radio on the International Space Station (ARISS) Program is
seeking formal and informal education institutions and organizations,
individually or working together, to host an Amateur Radio contact with a
crew
member on board the ISS. ARISS anticipates that the contact would be held
between January 1, 2018 and June 30, 2018. Crew scheduling and ISS orbits
will
determine the exact contact dates. To maximize these radio contact
opportunities, ARISS is looking for organizations that will draw large
numbers of
participants and integrate the contact into a well-developed education
plan.
The deadline to submit a proposal is April 15, 2017. Proposal information
and documents can be found at www.arrl.org/hosting-an-ariss-contact.
The Opportunity
Crew members aboard the International Space Station will participate in
scheduled Amateur Radio contacts. These radio contacts are approximately 10
minutes in length and allow students to interact with the astronauts through
a question-and-answer session.
An ARISS contact is a voice-only communication opportunity via Amateur
Radio between astronauts and cosmonauts aboard the space station and
classrooms and communities. ARISS contacts afford education audiences the
opportunity to learn firsthand from astronauts what it is like to live and
work in
space and to learn about space research conducted on the ISS. Students also
will have an opportunity to learn about satellite communication, wireless
technology, and radio science. Because of the nature of human spaceflight and
the complexity of scheduling activities aboard the ISS, organizations must
demonstrate flexibility to accommodate changes in dates and times of the
radio contact.
Amateur Radio organizations around the world, NASA, and space agencies in
Russia, Canada, Japan and Europe sponsor this educational opportunity by
providing the equipment and operational support to enable direct
communication between crew on the ISS and students around the world via
Amateur Radio.
In the US, the program is managed by AMSAT (Radio Amateur Satellite
Corporation) and ARRL (American Radio Relay League) in partnership with
NASA and
CASIS (Center for the Advancement of Science in Space).
More Information
Interested parties can find more information about the program at
www.ariss.org and www.arrl.org/ARISS.

I have two Advance Research Pre-amps on order. Both a MSP144VDG-160 &
MSP432VDG-160 which are going to be installed local in the shack. The
reason being is that I have 2 switchable array's. One is my M2 2M/70cm
satellite array and the other is my 2M/70cm LFA array. I generally only use
one array or the other.
My coax runs are short and I want to keep the pre-amp inside out of the
weather.
Here is my question. I can either feed 12V to each preamp and have a on-off
switch to manually select the one I want, or I can feed power to them via
coax that the 9100 supplies by turning on the 144 and 432 pre-amp On-Off
selections in the 9100 menu. I would rather go with the 9100 supplying the
pre-amp relay power instead manually supplying separate power.
Here is what I need to know, in single band operation I know that each
pre-amp relay would activate when on a particular band either 144 or 432.
But what happens in satellite mode? Are they both active at the same time?
I'm concerned about relay activations. I keep hearing about sequencers, is
this required?
Let me know.

Those preamps have RF switching. If they have the RF choke in them to feed
DC up the coax (see last paragraph at
http://www.advancedreceiver.com/page10.html), turn the preamp power on for
both bands in the 9100 and forget about them. When you transmit, the
corresponding preamp will bypass as designed. If they don't have the coax
power option, feed 12v to the power connector and carry on. No need for
sequencers. You will need to be careful of anything that introduces a short
in the feedline between preamp and transceiver, like grounded coax switches.
If you short the coax, the 9100 will sense an overload and shut off preamp
power. I'm not sure how many times this will work, so I try to not let it
happen with mine.
I would be remiss if I didn't mention that they will work -much- better
mounted at the antenna instead of inside, especially on UHF. Put them in a
2nd enclosure of some sort, like a plastic NEMA box, if you worry about
weatherproofing.

I think I'm using the same pre-amps that you are, but a different radio
(Yaesu FT-736). The pre-amps are used almost exclusively on satellite. I
completely manually control the pre-amps from a box I built with controls
for the two pre-amps and polarity switching relays. I have separate power
lines to the pre-amps.
I'm with Andrew in that you should mount them at the antenna. Mine are
also pretty short coax runs. There is a photo on my website that shows the
NEMA box with the two pre-amps mounted just below the rotors. It's a
little hard to tell that it's two pre-amps, but there really are two
stacked one in front of the other. The page is:

Hi folks,
The grid expedition to FO00 is over, and it was a success despite the
technical problems I was experiencing.
Many months ago, in my satellite infancy, I removed the stock diplexer from
my Arrow antenna and replaced it with a Comet (or Diamond?) diplexer. The
commercial diplexer was built in a heavy cast cabinet and used SO-239
connectors. It was big and heavy, so I took it apart and installed it in a
small Hammond diecast aluminum cabinet with BNC connectors. Much smaller
and lighter. I attached it to the Arrow's boom it worked like a charm up
until last weekend.
Late Saturday night, while struggling in the dark to connect a cable to the
diplexer I noticed that one of the female BNCs on the cabinet kept spinning
as I attempted to lock the cable into place. Eureka!
I opened up the diplexer cabinet later that night and found that while the
center conductor connection was still solid, the ground/shield connection
was shaky at best. I tightened it as best as I could and the problem went
away!
I want to thank you all for the many helpful responses. I read all of them
carefully and followed all of the suggestions, to the extent that I
could...800 km from home and with only a Swiss Army knife and needlenose
pliers with me.
73 and thank you again!

I just checked the SWR using my
FT-817ND's built in meter.? I connected
directly from the 817 to the appropriate connector on the
Arrow.
At 435 MHz the SWR meter shows 5 bars, which doesn't sound
good to me.
At 145 MHz I get a very brief indication of 6(?) bars and
then the the
bars immediately disappear.? This sounds to me like a
protection circuit
engaging, and subsequent presses of the mic button produces
no output.?
It also explains why I practically never get into SO-50.
The FT-817 manual is silent on the meaning of the bars on
the SWR
meter.? Does anybody have an knowledge of the 817's SWR
meter that they
could pass along to me?? Any assistance would be very
gratefully received!
Many thanks in advance,
Ken

I almost suggested removing the Arrow diplexer if you had one and
connecting the radio or meeter directly to see if it was the antenna
or diplexer, but since you were using an 817 I figured you had two and
were operating full duplex without a diplexer.

Grid chasers,
It is a pleasure to announce a real activation of the much sought after
Delta Mike Zero Two. There seems to have been only two passes worked from
here in the last 11 years, that is about to change.
Activations of rare grids should be done with enough preparation to avoid
missed passes. That said, I've invited two other ops to help assure our
success and maximize linear transponder passes. Our special guests will be
none other than Wyatt AC0RA and Gabe NJ7H. I am more than confident in their
rover skill levels and ability to maintain a functional station. They have
also proven to be capable of working through unforeseen equipment troubles.
Typical precautions apply. If you have linear capabilities please work us on
the transponders. Our FM only friends deserve a chance at scoring a rare
grid and tying up the bird helps nobody. On linear please be cognizant of
your power level. I know at least two of us will be using our regular
portable stations that are 5 watts max, QRO stations on the transponder will
make us difficult to hear. Also, please be aware of the footprint for other
ops. Nothing good comes from a left coast station getting in the middle of
us trying to work the right coast.
All QSOs will be uploaded to LoTW as promptly as possible and paper will be
sent to shore via torpedo.
Last but not least, when is it going to happen? Due to various environmental
aspects, firm departure and arrival times are not set in stone. However, we
can say that it will be the weekend of April 28th. When you hear K6G you
will know that 02 will be on. We will have plenty of time to work many
passes and none of us are afraid to work any pass no matter how shallow it
may be. I may continue normal ops leading up to departure to ensure my
station performs as expected.
73 and good luck,
Mike Diehl

As has been reported before, excess power to AO-07 can cause a reset of
the transponder. While monitoring AO-07 today, I heard it switch off
during a QSO in process. Power should be reduced to the minimum required
to hear your downlink.
On the previous pass of the satellite while it was out over the
Atlantic, I called CQ on SSB throughout the pass without resetting the
transponder. Unfortunately, no other stations were heard on the
satellite. I was using a panadapter to monitor the full pass band.
73,
