Dutch Amateur Radio Satellite User Day ? September 28th 2013
On Saturday September 28th, the very first Amateur Radio Satellite User Day
will be organized.
Location
The event will take place at restaurant ?Binnenhof?, in the small town of
Paasloo, in the North of the Netherlands, a 90 minute drive by car from
Amsterdam.
Join us!
We invite everyone to come over and join us! For both newbies as well as
experienced satellite operators it will be an exciting day with interesting
presentations as well as exciting activities!
Two Dutch satellite builders will talk about their latest satellites, that
both will be launched in November: FUNCube-1 (Wouter Weggelaar ? PA3WEG) and
Delfi-n3Xt (Jasper Bouwmeester). Both projects will take along with them
engineering models: a great opportunity to see yourself how small and
advanced Cubesats look like!
Furthermore we have many hands-on sessions planned: take your own radio and
antenna to Paasloo, we can help you get started or you can compare yours to
that of the others!
Of course this is a fantastic opportunity to ?meet and great? each other in
person. The OSCAR lunch has a lot of time reserved for that as well. The
entire day is free of charge, including coffee and lunch. From those that
want to stay for the Barbecue at the end of the day we ask a contribution of
17,50 euro.
For those that cannot come over to the Netherlands: meet us during one of
the hands-on sessions (see the program details below).
Program
10:00 Arrival
Coffee and tea, registration
10:30 - 10:45 Hands-on session VO-52
Listen to, and maybe even make a QSO via, the strongest linear transponder
currently in space. We do have a low elevation pass, need to check
line-of-sight.
2m/70cm SSB transponder, maximum elevation 11 degrees
10:45 - 11:00 Welcome
Opening of both the ?VHF-day? and the ?Amateur Radio Satellite User Day?
10:43 ? 11:02 Hands-on session HO-68
Listening to the CW downlink signals of this Chinese satellite. Its linear
transponder is no longer functional, but its beacon is great fun to
experiment with for reception of amateur radio satellites. Examples include
testing and comparing different types of antennas.
70 cm CW beacon. Maximum elevation: 49 degrees
11:04 ? 11:24 Hands-on session FO-29
Listening to, and maybe make a QSO via, the linear transponder of this
satellite. A very distant satellite for portable equipment, but with a
little bit of effort and luck we should be able to hear our own signals back
on downlink.
2m/70cm SSB transponder. Maximum elevation: 73 degrees.
11:30 - 11:35 Welcome Amateur Radio Satellite User Day
Opening of the very first Amateur Radio Satellite User Day in The
Netherlands.
11:35 - 12:15 FUNcube-1 ? A new satellite revealed (Wouter Weggelaar ?
PA3WEG)
A presentation by one of the builders, about the technology used in
FUNcube-1, a project of a series of organizations, including AMSAT-UK. Due
to the delayed launch (now planned for November) FUNcube-1 is not yet in
space during the event, but very likely Wouter will bring along the
functional engineering-model of FUNCube-1. A presentation you don?t want to
miss!
12:15 - 13:00 Amateur Radio Satellites step-by-step, for newbies and
experienced operators! (Ivo Klinkert - PA1IVO and Henk Hamoen - PA3GUO)
An introduction into orbits of LEO/HEO-satellites and how to predict their
passes. We will also talk about which kind of equipment is needed to
transmit via amateur radio satellites. So, a talk on TLE, AOS, LOS, TCA,
Kepler and Doppler, RHCP, LHCP, PCs, Antennes, TRX, SDR and Cubesat CW
beacons. While this session addresses the basics of satellite
communications, we invite the more experienced operators to share their
experiences during the presentation as well. For example which software they
use, which satellites are favorite, which antennas and rotators are being
used? and: which transceivers are most popular.
13:00 ? 13:45 Hands-on session FUNCube-1 Engineering model
Most likely it will be possible to make in Paasloo QSO?s via the transponder
of the engineering-model of FUNCube-1. A fun exercise or simply a lot of fun
with a satellite of which we really control when it is within reach! 2m/70cm
SSB transponder.
13:00 ? 14:00 OSCAR-lunch
Extended buffet lunch buffet, where the objective is to meet and great your
fellow radio amateurs that share the same interest amateur radio satellites.
At the same time a demonstration of the famous FUNcube Dongle and equipment
like Arrow antennas, LVB-tracker, etc.
13:45 ? 14:15 Hands-on session LO-19
Receiving the downlink signals of the satellite. Even though this satellite
has gone through some rough situations up there in space, we can still hear
a very strong (continues) carrier in the 70cm band. A great opportunity to
observe the Doppler-effect and to experience how large this effect is at
different stages of a pass. Or: compare again the performance of the
different antennas that will be brought by visitors.
70 cm constant carrier. Maximum elevation: 59 degrees
14:15 - 15:00 Delfi-n3Xt (Jasper Bouwmeester - Program Manager TU/d)
An update on the status of the next Dutch satellite of the University of
Delft (TU/d), which will be launched in November. Also here a lot of
interesting hardware will be shown, including the engineering model of the
S-band transmitter, the positioning system and the VHF/UHF antennas.
15:00 - 15:15 Radio Amateurs and scientific satellites (Henk Hamoen ?
PA3GUO)
How radio amateurs can contribute to scientific research in satellite
projects. No QSOs therefore, but rather support of science in space.
15:15 - 15:35 A portable, multi-functional satellite station (Ivo Klinkert
? PA1IVO)
A presentation on a portable satellite station for radio communications
using low earth orbit (LEO) satellites, multi-mode, including S-band
reception.
15:35 - 15:45 How to apply for an ARISS school contact (Bertus H?sken ?
PE1KEH)
How to apply for a school contact with the International Space Station (ISS)
via ARISS.
15:45 - 16:00 AMSAT-NL (Wouter Weggelaar ? PA3WEG, Chairman AMSAT-NL)
How and why AMSAT-NL was founded.
16:00 - 16:15 Future of the ?Amateur Radio Satellite User Day? (Ivo -
PA1IVO en Henk - PA3GUO)
Evaluation and gathering of ideas for the event next year.
16:15 Closure
BBQ for those that upfront signed up.
18:23 - 18:35 Hands-on session VO-52
For those that can get enough of it!
2m/70cm SSB transponder. Maximum elevation: 30 degrees.
Much more information (for example regarding registration) is available on
this website:

As far as I know there are no transponders on any of the qubesats being
lauched. These are femtosats measuring 50cm (2 in) on a side and weighing
less than 200 grams. The link budget is quite challenging with the available
power budget. A transponder on this platform would need to be more power
efficient in both the uplink and downlink paths than any other ham satellite
to date. This would need to be accomplished in a form factor smaller than
any ham satellite to date. These first launches are an effort to baseline
the feasibility of the platform and lower the entry point for educational
access to space. There are many ways to possibly make a platform this size
into a usable communications medium, but FM voice is definitely not one of
them, and SSB would be very weak signal at best.

If someone will build a linear PSK-31 transponder, I have a launch
opportunity in 9 months.
All it needs to be is a PSK31 Linear receiver on 28.120 MHz (3 KHz
bandwidth) with AGC coupled to a downlink UHF FM transmitter of about 1
Watt. Should fit on a 3.5" square card. This is the same as Brno
University has built for prior missions of PCSAT2 on the ISS back in 2006
and the two on the shelf awaiting flights.
Flight delivery by May 2014 (9 months from now).
Brno, may not have the man power to make a third one for this new flight
opportunity.
Jusst a thought for someone looking for a project.

Unrealistic, unacheivable, impossible and so on that's what i hear since
AO-40 stop working. I pledge for an AMSAT'S join funding venture
years ago. Lets say 8000,000$ to reach just with the AMSAT-NA estimated
membership of 3000 plus the other world AMSAT'S estimated at
another 3000 making a total of 6000 contributors, who with a special
annual fund raising of 200$ to pay for P3E launch, this 8 millions
can reach in +/- 6 years. Is it possible to have governments paying a part
of it? Making P3E a commercial sponsored satellite? What about
the new rocket launching company who can piggy back P3E: Roscocosmos,
Virgin,ESA. and all the ther potential contributors: university,
science group of interest , cellular phone company...
If you put all various international AMSAT'S already available funds for all
the different cube sats projects together, plus if we added a
sound financing plan, could be more will be interested to invest more money?
this 8 millions $ can probably be reach in 3 years or less.
What about the BOD'S visions and planning of these AMSAT'S groups did they
at least look at it?
A soon as someone try to launch an idea there is automatically someone who
jump on the case accusing them to be unrealistic, dreamers and
so on. It is not surprising with this attitude some of the world greatest
economy struggle to survive?
Yes I know we have to pay more but it's the actual trend if we want an HEO
we will have to pay more for it "No money no candy"
Be positive and work toward an already near completed satellite (P3E) that's
why the BOD'S are elected to lead toward the best not the
less... Yes we can someone says!

While anything is possible I will be very surprised (pleasntly) if there is
another amateur radio satellite with a liquid propulsion system that is
managed by any amateur group that gets a ride into any sort of HEO transfer
orbit.Ion engines might be different but after AO-40 and its propulsion
issues the days of amateurs playing with rocket engines on commercial
flights I suspect is over.

Hi Bob,
I heard about you request on the Amsat BB for a 10M to uhf transponder. Can
you give me some additional data on the dc input supply and sensitivity for
the 10M link? Also do you have an assigned transmit frequency yet? I have
built several 10M to VHF true linear translators which have flown on
balloons and have a design in mind that might do for your project, a single
conversion 10M receiver to audio which is then used to modulate the uhf or
vhf transmitter.

We're supposed to somehow convince someone to let us tack our semitested

Astronaut Luca was just heard wonderfully here in Southern California,
answering inquiries.
Couldn't hear a peep on Echolink. And the live audio feed page cited
was not loading at all. BUT it sounded great on the downlonk!

Nice thought Luc, but I'd query the numbers.
You suggest there may be 3000 members of AMSAT groups outside the
USA/Canada, I say 700 would be a better estimate, I'd like to be proved
wrong but I think you'll find a number of national AMSAT groups have a
membership of fewer than 50.
The figure you quote for AMSAT-NA includes Life-members, by definition once
a Life-member always a Life-member even if they gave up satellites years ago
and are now living in retirement homes. AMSAT-NA sold a large number of
Life-memberships in the 1970's at what now seems a very low price. I believe
the number of AMSAT-NA members who actually pay an annual subscription is
around 1500. A number of overseas amateurs are also AMSAT-NA members, so the
number of annual subscription paying? US/Canadian members will be less than
1500.
So it's likely that the world-wide total of subscription paying members of
the various AMSAT groups could be under 2000. To raise $10m over six years
every single one of them would have to pay $833 a year, I just can't see
that happening.
The costs for launching a single P3E satellite are simply too much for AMSAT
members alone to sustain, to get to amateur payloads to MEO/HEO/GEO will
take collaborative ventures with other organizations, Educational,
Government or Commercial.
