2. RAGazine
The 3rd edition of the RAG quarterly newsletter is now available for download from the BAA RAG website (see above).  This edition contains Karl Jansky’s 1932 paper identifying additional radio noise to that originating from thunderstorms, a review of the recent book on the life and times of Sir Bernard Lovell, and a description of the Siberian Solar Radio Telescope, along with articles on meteor scatter, magnetometry and VLF activity, plus Tony Abbey’s Technology Watch column.

We are always on the look-out for material for RAGazine.  The publication is an informal newsletter for sharing information and experiences in amateur radio astronomy and geophysics and we do depend upon input from those reading it.  We would like to move to publishing every other month, rather than quarterly, provided we can get a steady supply of material.  The Editor (Dave James) is keen to feature members’ home observatories, outreach activities, co-operative ventures and the like. We would also like to find one or two more contributing editors or correspondents for specific areas who can provide regular material on particular areas they feel would be of interest to readers.

If you can offer anything here please contact the Editor – dave<at>

3. HLOG project
The Hydrogen Line Observing Group was set up by Gordon Dennis and Brain Coleman to make use of Brian’s 3.7m diameter dish at Redenham Observatory for measuring Hydrogen Line emissions from the Galactic Plane.  Despite the high winds earlier in the year which twice damaged the azimuth gear box, observations have been largely completed from Galactic Longitude 20 to 94 degrees with some observations at 108, 110 and 180 degrees. The team is now looking for additional volunteers to extend the survey to at least 120 degrees longitude and maybe to 180 and beyond, plus an increased range of latitudes, in some cases as far as ± 14 degrees to capture all the “structure” detectable with the instrument.  Help is also needed to process the resultant data and re-check observations.

The project provides you with an opportunity to do some serious observing with a decent size dish.  All you need to participate is internet access and the time to set up and monitor individual scans.  As an observer you have access to the data collected by the whole Group for your own analysis work.

Those wishing to join the team should contact Gordon Dennis at gordon.dennis<at>

Best wishes

The STELAR Project 2014

STELAR Logo SmallThe education and science charity STELAR has been active in promoting radiocommunications in schools and colleges for over 20 years, as part of curriculum enrichment and personal and professional development for teachers.

Through its specialist courses, it has achieved much notable success in establishing radio clubs in schools and inspiring young people to seek careers in science, electronics and industry. It has played a major role in space and satellite communications in schools.

In 2013 it provided opportunities for satellite experiment by offering SDR receivers to schools allowing them to participate in the current series of FUNCUBE satellite experiments.

Now in 2014 STELAR is offering a new challenge to educators both professional and Amateur. The phenomenal success of the Raspberry Pi computer has opened up new opportunities and stimulated demand for educational projects linking communications systems, via computers.

This year STELAR is seeking to support the very best of those ideas by making available grants to educational groups, with projects designed to stimulate experiments with radio linked computing.

Typically these might take the form of:
• Radio systems linked to but not exclusively, a Raspberry Pi, computer.
• A detailed Teachers guide to the use and benefits of FUNCUBE or similar satellite systems in schools,
• The creation of radio-science projects to aid teachers personal and professional development.

Educational groups can apply for funding to develop a project of their choice, by submitting ideas for consideration by June 30, 2014. Groups should set out their aims and giving as much detail as possible. Successful entries will be notified during the Autumn term.

Interested ? then make contact by visiting the STELAR website

Configuration 4 was used:
* ARISS antenna 43
* Frequency 2395 MHz
* Symbol rate 2.0 MS/s

Ground stations G4KLB, F6DZP, IK1SLD and KI (Livorno) received the signals and streamed the video over the BATC server. The DATV signal was received for about 6 minutes.

Commander Wakata congratulated ARISS for this achievement and answered a series of questions, prepared in the manner of a school contact. He also proceeded to a microgravity experiment.

Congratulations to the Ham Video team for this outstanding performance.

Next step should be a video enhanced ARISS school contact. We will keep you informed on any progress.

Juno spacecraft QSL cards sent out

Juno Spacecraft QSL Card October 9, 2013

Juno spacecraft QSL card October 9, 2013

Juno QSL cards have been sent out to those radio amateurs who participated in the Juno Earth flyby experiment.

Amateur radio operators sent a very slow CW (1/25 WPM) to NASA’s Juno spacecraft during its Earth flyby on October 9, 2013.

Hams sent “HI” every 10 minutes as Juno approached Earth, and the message was clearly detected several times. The Juno team confirmed that more than 1400 radio hams participated, representing all seven continents.

The KickSat CubeSat will carry 104 tiny Sprite satellites into a 325×315 km 51.5 degree inclination orbit. The launch carrying four other CubeSats, SporeSat, TSAT, PhoneSat-v2.5 and ALL-STAR/THEIA is planned for Friday, April 18, 2014 at 1925 UT and should be broadcast live on NASA TV and also streamed on Ustream.

Zac writes:

Our launch coming up in less than a week and, to keep things fun, 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!

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.

Solar powered 434 MHz balloon reaches Syria

Track of the B-44 balloon launched from Silverstone, UK

Track of the B-44 balloon launched from Silverstone, UK

On Tuesday, April 8, 2014 radio amateur Leo Bodnar M0XER launched two foil “party” pico balloons from Silverstone with solar powered payloads transmitting on 434.500 MHz USB using the Contestia 8/1000 data mode. By Thursday, April 10 one of the balloons, B-44, was reported to be over Syria.

Depending on altitude the balloons could have a range of 300-500 km and remain aloft for several days.

Balloons: 90cm Qualatex foil party balloon
Payloads: 12 grams solar powered tracker
Telemetry: 434.500 MHz, USB, vertical polarisation, Contestia 8/1000
B-44 is 1500Hz higher than B-43 so it should be possible to see both in the same audio bandwidth.

These balloons use digital mode “Contestia 8/1000″. Unfortunately it is not possible to automatically configure this mode in dl-fldigi. Therefore please follow this procedure:
• Autoconfigure B-43 or B-44 flight as usual.  This will default to DOMX 16 mode.
• Select menu option  Op Mode -> Contestia ->  8/1000.  The bottom left corner of dl-fldigi should now read CTSTIA 8/1000
• Enable RxID button at the top right corner of dl-fldigi.

Downlink data contains two lines of telemetry every 4 minutes.Time between telemetry data is filled with beeps at 3 sec intervals.

Leo says “I appreciate help of everybody who joins in for tracking!”
