The Basement Satellite at Canadian Documentary Film Festival

The Basement Satellite posterThe first screening of the The Basement Satellite at the Canadian International Documentary Film Festival takes place on Friday, April 25.

The film, directed by Hyoung-ju Kim, tells the struggle of Korean artist Hojun Song DS1SBO to develop a satellite, OSSI-1, in his basement studio and launch it into space.

Synopsis from Indiewire.comIn his Mangwon-dong basement art studio, a media artist Hojun Song dreams of making a satellite and shooting it out to space.

He wants to make his dream real through OSSI (Open Source Satellite Initiative) movement. He tries to build a DIY satellite, and to sell 10,000 T-shirts for the 100 million Won ($100,000) budget. His seemingly reckless and utterly ambitious project begins. Would his dream become real?

144 and 432 MHz mixed mode helix antennas

144 MHz prototype helix antenna

144 MHz prototype helix antenna

Martin Ehrenfried G8JNJ has developed omni-direction helix antennas for 144 and 432 MHz which have proved effective for high altitude balloon and satellite reception at the SUWS WebSDR.

Martin says “I had been experimenting with single turn ‘twisted halo’ design, and decided to try stacking them to see if I could achieve more gain. Modelling suggested that a stretched 3 turn helix with a helix circumference of approx 1/2 wave length and an overall length of 1/2 wave at 70cm, and fed with a gamma match at the centre would offer reasonable gain, an omni-directional pattern and mixed polarisation.”

Shin-En2 to carry Mode J linear transponder

Shin-En2 satellite

Shin-En2 satellite

Shin-En2 is a 2.85 kg satellite measuring 490×490×475 mm built by students at Kagoshima University in Japan that will carry a 145 to 435 MHz linear transponder into a deep space orbit.

The aims of the mission are:
• To establish communication technologies with a long range as far as moon.
• To establish a new technology of the ultra-light-weight satellite. Proposing a WSJT 29dBm UHF downlink and a 29dBm 20 kHz linear transponder and a CW beacon all on UHF with a VHF uplink for the transponder

The orbit will be quite different from the previous satellites. Shin-En2 will have an elliptic orbit around the Sun and travel to a deep space orbit between Venus and Mars. Its inclination will be almost zero, which means Shin-En2 will stay in the Earth’s equatorial plane. 

The distance from the Sun will be between 0.7 and 1.3 AU, where AU (Astronomical Unit) is approximately 1.5 x 108 km.

Shin-En2 is expected to launch in the 4th quarter of 2014 with another amateur radio satellite ARTSAT2:DESPATCH on a H-IIA rocket with the asteroid explorer Hayabusa 2 as the main payload.

LituanicaSAT-1 Camera and FM Voice Transponder

The LituanicaSAT-1 team are carrying out a test of the FM transponder and they request reports. [Latest update added April 23 1839 UT]



Dear amateur satellite radio operators,

A courtesy notice that LituanicaSAT-1 FM transponder test is in progress. Today we performed initial operational test over Lithuania successfully. Downlink frequency was noted to have shifted to 435.1755 MHz. More tests are needed to verify that and determine exact uplink frequency shift but 145.950 MHz should work.

Please remember to use CTCSS PL 67 Hz sub-tone. If no problems will be encountered the operational tests for 23rd of April are planned to resume on 12:45 UTC and finish on 16:00 UTC. Just after activation you should here callsign in Morse and short salutation message from Lithuanian president. This identification message is transmitted every 5 min if there is no radio activity as well.

Your reports are more than welcome. Please submit your reports to (please provide some supporting data like frequencies, max elevation of the pass, signal to noise ratio, etc.). Also please feel free to share this information through any media channels.

Best Regards,
LituanicaSAT-1 team

UPDATE April 23 1839 UT

Dear radio amateur operators,

Thanks for all of your reports from today’s successful transponder test!

During 14:20 UTC pass over Lithuania FM transponder has switched off automatically after mode transitioning telecommand has been sent to the satellite. This was standard test procedure to verify correct operation of the on board computer during operation of the transponder.

Next test is scheduled for Apr 24 from 13:30 UTC to 15:00 UTC. Again we will be grateful to your reports, including FSK packet telemetry on 437.544 MHz. Please respect other radio amateurs and obey transponder operating techniques.

They are also invited to submit papers for subsequent publishing on the AMSAT-UK web site. We normally prefer authors to present talks themselves rather than having someone else give them in the authors’ absence. We also welcome “unpresented” papers for the web site.

This year we are able to offer  limited financial support for young speakers—please contact Jim Heck email g3wgm -AT- for information about this.

Generally, submissions should be sent to Trevor M5AKA: e-mail:  m5aka -AT-

AMSAT-UK also invites anyone with requests for Program Topics to submit them as soon as possible to M5AKA.  Invitations for any papers on specific subjects will be included in the future call. Likewise if anyone knows of a good speaker, please send contact and other information to M5AKA.

Monitoring AO-73 with Minimalist Equipment

In this video Clint Bradford K6LCS demonstrates that a simple antenna is all you need to get a signal the FUNcube-1 (AO-73) telemetry beacon.

Clint writes: AO-73 just passed to the West over Southern California. With just a tape measure beam and a Yaesu FT-60R, it was received. AO-73 is transmitting at about 30 mW on 145.935 MHz today in the sun, and was never closer than about 450 miles.

Watch Monitoring AO-73 – Minimalist Equipment

In the video Clint was also using an  iPod touch, running the satellite tracking App PocketSat3 from

The AO-73 beacon uses BPSK modulation. To demodulate and decode the telemetry data you need a SSB receiver (FT-817, RTL-SDR, FUNcube Dongle, etc)  and the free Dashboard software. Clint made the video at the weekend when the beacon was in low power mode running just 30 mW. During the daylight hours on Monday-Friday the beacon runs 300 mW output so would be an even stronger signal.

Zac Manchester KD2BHC says:

After a beautiful launch KickSat was deployed in low Earth orbit. We at Cornell and several amateur radio operators around the world have made contact with the spacecraft and it is alive and well. I can’t thank all of you enough for your tremendous support over the past two years. Thank you for believing in KickSat!

This is the culmination of a lot of hard work and is a huge milestone, but we’re not done yet. In 16 days the Sprites will deploy from KickSat. We need as many people as possible listening in, so if you’re interested, please check out the wiki and our mailing list for more information. As always, don’t hesitate to contact me with questions.

The CubeSats KickSat, SporeSat, TSAT, PhoneSat-v2.5 and ALL-STAR/THEIA were deployed into a 325×315 km 51.5 degree inclination orbit.

On the KickSat updates page Zac Manchester KD2BHC has announced a competition to receive the first amateur radio signals from the KickSat CubeSat and the tiny Sprites satellites.

Zac writes: I’d like to announce a little contest…

I’ll be offering prizes to the first several people who receive telemetry packets from KickSat as well as the first few who receive signals from the Sprites. The prizes will include souvenir Sprites and CRS-3 and ELaNa-V mission patches.

437 MHz Sprite

437 MHz Sprite

Now for the rules:
• In the case of KickSat telemetry, you have to send me the raw hex or ASCII packet data and I have to be able to successfully decode it.
• In the case of the Sprite signals, you have to send me a raw baseband recording and I have to be able to decode at least one Sprite signal from it.
• I’ll continue offering prizes until I run out of cool swag.
• I have the ultimate say on whether or not you win.

To get in on the fun, check out our wiki and join the KickSat mailing list. Let the games begin!

CRS-3 CubeSat frequency chart by Mike Rupprecht DK3WN

All the Sprites operate on a single frequency of 437.240 MHz and use Code Division Multiple Access (CDMA). The transmitter runs 10 mW output of Minimum Shift Keying (MSK) modulated binary data with each data bit modulated as a 511 bit Pseudo-Random Number (PRN) sequence. The ITU emission designator is 50K0G1D.

The KickSat CubeSat has downlinks on 437.505 MHz and 2401-2436.2 MHz.
