On the AMSAT Bulletin Board (AMSAT-BB) Bob Bruninga WB4APR writes:

If someone will build a linear PSK-31 transponder, I have a launch opportunity in 9 months.

All it needs to be is a PSK-31 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 of Technology 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 University, may not have the people to make a third one for this new flight opportunity.

Just a thought for someone looking for a project.

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 on-air 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”

HO-68

HO-68

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.

Amateur Radio Satellite FO-29

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.

AMSAT-SM compares FUNcube Dongle Pro+ and RTL SDR’s

FUNcube Dongle Pro+ Software Defined Radio

FUNcube Dongle Pro+ Software Defined Radio

AMSAT-SM has published a comparison of the FUNcube Dongle Pro+ and the RTL TV dongle based software defined radio.

The FCD Pro+ costs about 10 times the price of the RTL TV Dongle. While the FCD Pro+ has a far wider frequency coverage enabling reception of LF, MF and HF are there any other differences ?

Read the AMSAT-SM comparison in Google English at http://tinyurl.com/FUNcubeDongle-RTL-Comparison

The FUNcube Dongle (FCD) Software Defined Radio (SDR) was originally developed for educational outreach as part of the ground segment for the FUNcube satellite. A proportion of the sales of the FCD goes to support AMSAT-UK’s FUNcube satellite.

The Basic Low Earth Orbit UNSW Experimental Satellite, better known as BLUEsat, will undergo a test flight in April ahead of its launch into space.

BLUEsat, a 260mm cube weighing around 13 kilograms, will carry a flight computer with transmissions to include a beacon and amateur packet radio using the AX.25 packet radio protocol in a “mode J” VHF/UHF configuration.

Once in orbit BLUEsat will be a digital amateur radio satellite, which means that voice and data files can be uploaded to it by any amateur radio operator in the world over which the satellite passes.

The Canadian ConSat-1 3U CubeSat aims to analyze radiation characteristics in the South-Atlantic Anomaly, and test technology payloads.

Canada is an Associate Member of the European Space Agency (ESA) and ConSat-1 is one of the educational CubeSats chosen for Phase 1 of the ‘Fly Your Satellite!’ initiative.

The ‘Fly Your Satellite!’ initiative builds on the success of the ‘CubeSats for the Vega Maiden Flight’ pilot program. This culminated in 2012 with the launch of seven student-built CubeSats on the first flight of the new ESA Vega launcher.

The South-Atlantic Anomaly is a plasma cloud 200 km from the Earth’s surface, located above the east coast of South America. It appears to be constantly growing in size and a NASA report speculates that by 2240 it might cover approximately half the southern hemisphere. http://ntrs.nasa.gov/archive/nasa/casi.ntrs.nasa.gov/20000085550_2000122978.pdf

ConSat-1 plans to look at various aspects of the plasma cloud: its temperature, its atomic and molecular composition, its density, and its volume. The team hope to produce meaningful data which shows the ever-changing characteristics of this extra-spatial hazard.

In this video Nick Sweet of Space Concordia describes his teams winning CubeSat entry and provides an insightful look into the Canadian Satellite Design Challenge at the 2012 Canadian Space Summit.
