AMSAT NEWS SERVICE ANS-065 ANS is a free, weekly, news and information service of AMSAT North America, The Radio Amateur Satellite Corporation. ANS reports on the activities of a worldwide group of Amateur Radio operators who share an active interest in designing, building, launching and communicating through analog and digital Amateur Radio satellites. Please send any amateur satellite news or reports to: ans-editor(a)amsat.org In this edition: * AO-51 Configuration Plans Still Affected by Eclipses * ARISSat-1 to be Activated Aboard ISS on April 12 * AMSAT Heading For Dayton Hamvention * NASA Glory Satellite and Three CubeSats Lost Vandenberg Launch Failure * Pakistan Developing Student CubeSat Projects * Satellite Shorts From All Over * NASA, Make Magazine Announce Competition to Fly Student Experiments SB SAT @ AMSAT $ANS-065.01 AO-51 Configuration Plans Still Affected by Eclipses AMSAT News Service Bulletin 065.01 >From AMSAT HQ SILVER SPRING, MD. March 6, 2011 To All RADIO AMATEURS BID: $ANS-065.01 AO-51 Command Station, Mark Hammond, N8MH reported that AO-51 is nearing the end of eclipse periods. Analysis of telemetry from the satellite shows that AO-51 is still not experiencing full sunlight, most likely due to spacecraft orientation and sun angle. On-board temperatures are climbing and the Command Team continues to monitor and tweak various power management parameters to take advantage of the solar power that is available. Helpful reports from users (about the transmitters turning OFF) and telemetry confirm that AO-51 is still seeing a few minutes of "dark- ness" every orbit. AO-51 was configured for "normal operational mode" on March 3, and will remain in this configuration until further notice. That includes the V/U repeater the Packet BBS with L-band uplink: AO-51 Schedule as of March 3: Mode V/U FM Voice Repeater (no PL tone needed) Uplink: 145.920 MHz FM Downlink 435.300 MHz FM Mode L/U PacSat BBS Uplink: 1268.703 MHz FSK 9k6 baud Downlink 435.150 MHz FSK 9k6 baud The Packet BBS will be open for use, but the Command Team asks for your cooperation (by standing by and not entering the queue) if you share the footprint with a command station (most often on the East coast of the US). Should conditions improve, there will be an attempt support some S-band operations--but for now that seems unlikely. The latest AO-51 status and configuration news will be posted on the amsat-bb and on the AO-51 Control Team News web page at: http://www.amsat.org/amsat-new/echo/CTNews.php [ANS thanks Mark Hammond, N8MH for the above information] /EX SB SAT @ AMSAT $ANS-065.02 ARISSat-1 to be Activated Aboard ISS on April 12 AMSAT News Service Bulletin 065.02 >From AMSAT HQ SILVER SPRING, MD.

March 6, 2011 To All RADIO AMATEURS BID: $ANS-065.07 In a press release titled, "NASA Launches 2011 Nationwide Technology Space Competition for Education", NASA says it's Emerging Commercial Space Office (ECSO) is teaming with Make Magazine, and Teachers in Space to help develop spaceflight kits that high school teachers and students can build and fly on suborbital flights. The NASA/Make competition is designed to inspire curiosity and create interest in science, technology, engineering and mathematics (STEM) among classroom teachers and their students. Contenders will be invit- ed to submit ideas, concepts and prototypes for kits that teachers and students can build for future spaceflights. Competition rules are simple. Kits should use components that are likely to be available at most high schools, and submitted experi- ments must be self-contained and fit in a standard Cubesat container. To make kits accessible to students nationwide, part of the challenge is to be able to build these kits for under $100, the kind of funds that could be raised by a school bake sale. The first experiment kits to be selected will fly aboard the Excelsior STEM mission, a commercial unmanned suborbital mission sponsored by Teachers in Space and scheduled to fly in 2011. Experiment kits for the Excelsior STEM mission will be assembled by teachers at a Suborb- ital Flight Experiment Workshop to be held August 1-5, 2011 at the NASA Dryden Flight Research Center's AERO Institute in Palmdale, Calif. The full NASA Press Release can be found on-line at: http://www.nasa.gov/centers/ames/news/releases/2011/11-14AR.html Make Magazine says more details about the challenge, including rules, prizes, etc., will be coming soon. If you'd like to participate in the MAKE Space Challenge, get on the mailing list! They will notify you the details for challenge have been finalized and when the application process opens. You can sign up for the Space Challenge mailing list at: http://blog.makezine.com/space [ANS thanks NASA and Make Magazine for the above information] /EX In addition to regular membership, AMSAT offers membership in the President's Club. Members of the President's Club, as sustaining donors to AMSAT Project Funds, will be eligible to receive additional benefits. Application forms are available from the AMSAT Office.

SSB
by Kevin Deane 06 Mar '11

06 Mar '11

I did not mean for my sarcasim to be insulting, I gather they must go hand in hand, my opologies... So I did find a hombrew 2-meter all band in the 1999 QST, Sept,Oct,Nov... called the DSP-10. A little more than I was looking for and I think it was discontinued. Several hundred were sold. http://www.proaxis.com/~boblark/dsp10.htm Goes to show it can be done. Roger I think said something about a downconverter, I do have an old 10-meter maybe that will work. Still would like to make a 2-meter and a 70cm SSB radio probly have to be two kits. Still searching I have sent like 20 e-mails to kit stores we shall see. Any more ideas would be great! Did I curb the sarcastic remarks? Oh that was one wasnt it...LOL Kevin

Is there another forum, because obviously everyone here just buys everything and maybe have forgotten what this hobby is all about! I know there is a kit out there for a receiver and or a SSB converter. 2-meter/70cm SSB receiver. I heard there was an article in QST so it must exist. I am young, enthusiastic, and have lots of time, any help would be great. :) Kevin KF7MYK

OSCAR-11 Report
by Clive Wallis 05 Mar '11

05 Mar '11

OSCAR-11 REPORT 04 March 2011 OSCAR-11 celebrated it's 27th birthday on 01 March! It was designed, built and launched within a period of six months, using commercially available 'off the shelf' components (COTS). Once again, congratulations to Professor Sir Martin Sweeting G3YJO, his team at the University of Surrey and groups of radio amateurs who also contributed to the project. Unfortunately, the satellite wasn't transmitting on its birthday, but resumed transmissions, three days later. This report covers the period from 31 January to 04 March 2011. During this time the satellite has been heard from 10 to 21 February and from 03 March 2011. It is expected to switch-off again 13 March until 23 March. Excellent signals have been reported from stations located around the world, and good copy obtained from decoded telemetry frames. The satellite is now transmitting during eclipses, although signals are weaker at those times. This indicates that there is still some capacity remaining in the battery. The on-board clock is now very stable. It gained *** seconds during the current reporting period. The VHF beacon frequency is 145.826 MHz. AFSK FM ASCII Telemetry At the present time, while OSCAR-11 is operating in a predictable way, I no longer need direct reports or files by e-mail. However, could all listeners continue to enter their reports on the general satellite status website. This is a very convenient and easy to use facility, which shows the current status of all the amateur satellites, and is of use to everyone. Reports around the expected times of switch-on and switch-off are of special interest, especially for times 12:00 - 17:00 and 22:00 - 07:00 UTC, to when the satellite is out-of-range in the UK . The URL is http://oscar.dcarr.org/index.php A longer version of this report report is available on my website, and new listeners to OSCAR-11 should read this for further information. The URL is www.g3cwv.co.uk/oscar11.htm . This page contains a links to the longer report, a short audio clip to help you identify the satellite and a file of the last telemetry received. The website also contains an archive of news & telemetry data which is updated from time to time, and details about using a soundcard or hardware demodulators for data capture. There is also software for capturing data, and decoding ASCII telemetry. If you place this bulletin on a terrestrial packet network, please use the bulletin identifier $BID:U2RPT154.CWV, to prevent duplication. 73 Clive G3CWV xxxxx(a)amsat.org (please replace the x's by g3cwv)

Hello Enzo, Yes, the 9k6 BBS is operational and working. Please adjust your uplink freqency (try UP and DOWN in 500 Hz or 1 kHz steps) and see if that helps. Most users report that a high gain antenna with 10-50 Watts power at the antenna for the L-band uplink results in success. I find 1268.705 works best for me, sometimes even .708. Also please check your AO-51 setup in Wisp/Satellite Setup. Broadcast Callsign must be PECHO-11 and BBS Callsign must be PECHO-12. There is no other active/functional BBS bird at 9k6, nor any with 1.2 GHz uplinks. Also---what TNC are you using for 9k6? I found out many years ago that AO-51 does not like the transmitted signal from my TAPR EVM56k DSP unit, so it rarely if ever heard me. 73, Mark N8MH At 02:52 PM 3/5/2011 +0100, Vincenzo Mone wrote: >Hi Folks, >I am trying the bird on: >9k6 BBS and Telemetry. >Does it work? >With the MSPE I can just receive numbers like: > >B:44253341 > >What does it mean? >I am trying to request the DIR on 1268.700 MHz, but I do not get any >response. >On the upper side of the MSPE program often I can read: > > Frames Heard from PACB-1 > >I am asking this because I would like to see if my system still works. >Is there any other Bird that I can use the 1.2 GHz Band? >Any help will be really appreciated >Thanks in advance. > >73 de Enzo IK8OZV >EasyLog 5 BetaTester >EasyLog PDA BetaTester >WinBollet BetaTester >D.C.I.
