SB SAT @ AMSAT $ANS-037.01 SKN Results
AMSAT News Service Bulletin 037.01 From AMSAT HQ SILVER SPRING, MD. February 6, 2011 To All RADIO AMATEURS BID: $ANS-037.01
Many thanks to all who participated in AMSAT's Straight Key Night on OSCAR 2011, this year's event held in memory of Dick Peacock, W2GFF. Despite the frequent necessary power-management shut-downs of AO-51, activity was generally good, with AO-7, FO-29 and VO-52 picking up the load. A big "Well Done!" to all of the command stations.
The following participants each received one or more "Best Fist" nominations:
AA5PK, JH7UJI, JM1SBU, JR0EFE, K9CIS, N1AIA, N4ZQ, N5AFV, N9AMW, ON5NY, PR7VX, PU4RON, VA7MG, W9EN, WA5KBH, WB2SIH, WC7V, WD9EWK, 9A2EY
As can be seen from the list, from its very modest, informal beginnings on the North American east coast AMSAT net in the 1970s, SKN on OSCAR is now a worldwide event. Long may it continue, and we hope to see you next year!
A Big well done to Ray for once again giving his time and Effort to compilation of the results and moderating the Straight Key Night.
73,
Ray, W2RS

SB SAT @ AMSAT $ANS-037.03 AO-11 Report
AMSAT News Service Bulletin 037.03 From AMSAT HQ SILVER SPRING, MD. February 6, 2011 To All RADIO AMATEURS BID: $ANS-037.03
OSCAR-11 REPORT 31 January 2011
This report covers the period from 31 December 2010 to 31 January 2011. During this time the satellite has been heard from 31 December 2010 to 10 January 2011, and from 21 January to 30 January . It is expected to switch-on again 10 February for ten days, and remain silent for the remainder of the month.
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 eight seconds during January.
The VHF beacon frequency is 145.826 MHz. AFSK FM ASCII Telemetry
Reception reports have been received from Christian SWL-CHMY, Mike DK3WN, Campo PY5JAP, Ron WB0SOK and Horatio CX8AF. Many thanks for those and to everyone who posted reports on the satellite status website.
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 u pdated 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.

SB SAT @ AMSAT $ANS-037.05 2 Notes from SA AMSAT
AMSAT News Service Bulletin 037.05 From AMSAT HQ SILVER SPRING, MD. February 6, 2011 To All RADIO AMATEURS BID: $ANS-037.05
*1 SA AMSAT Announces SAiSAT A Journey Into Tomorrow
This week SA AMSAT announced two new satellite initiatives. The first is a long-term research and development project called SAiSAT.
The Southern Africa Amateur Radio Satellite Association (SA AMSAT) which is affiliated to other AMSAT groups around the world is pro- posing an exciting satellite project and is inviting the partici- pation of South African Universities and Universities of Technology in the development and construction of a completely South African Amateur Radio experimental satellite.
The objective of this satellite is to demonstrate South Africa's ability to engineer a satellite, employing the latest technology, and new innovations. In addition to some feasibility projects for future commercial use. The aim of the project is to contribute to propelling South Africa into a world position as a technology resource.
SAiSAT is based on the CubeSat satellite design. SAiSAT plans to use fold out panel a total of 24 in all that support solar panel steering in order to capture the maximum energy available from the sun. The rear of the solar panels is free for project use. They have the potential to house 24 projects depending on size.
An additional research proposal is that the outer rim of each panel is fitted with pcb tracks in the form of a coil: + To generate additional power from the Earth's magnetic field. + To torque stabilise the satellite against the Earths magnetic field. + To give orientation data to resolve the attitude of the satellite. + Take additional unused power from the batteries and elevate the satellite into an every increasing orbit thus extending its use- fulness and orbital life. + Possible to create an 12 antenna arrary * Provide a steerable antenna array with gain, thus reducing the necessary radio frequency power needed to maintain contact with earth. * Provide a radio Doppler system on board so the satellite can confirm and report position, and supply the radial of interfering emissions. * Provide a vital radio redundancy feature from antenna failure. * Provide static charge data. * Provide residual atmospheric density readings
SA AMSAT has issued an open invitation to tertiary institutions and individuals to participate in the project. A project meeting is scheduled on Friday 25 March ahead of the annual Space Symposium which will take place the next day. Full details are posted at: http://www.amsatsa.org.za/SAiSAT.htm
*2 SA AMSAT Announces Kletskous Amateur Radio Satellite Project
Project Manager Hannes Coetzee, ZS6BZP invites amateur satellite operators world-wide to monitor the SA AMSAT web page for project plans of the Kletskous satellite. (http://www.amsatsa.org.za)
Kletskous is a hands-on CubeSat aimed at promoting greater involve- ment in satellite activity by South African Radio Amateurs. The first draft of a project plan will be available soon on the SA AMSAT web. Regular updates will be posted as the project develops.
Hannes is inviting interested persons to join the team. "We are par- ticularly looking for radio amateurs with RF design experience, antenna design experience and software writing experience. Send your contact details and a short description of you technical background to [email protected].

SB SAT @ AMSAT $ANS-037.06 ARRL Announces Teachers Institute TI-2 Space Curriculum
AMSAT News Service Bulletin 037.06 From AMSAT HQ SILVER SPRING, MD. February 6, 2011 To All RADIO AMATEURS BID: $ANS-037.06
ARRL Announces Teachers Institute TI-2 Space Curriculum
The ARRL Education Services Department has announced the 2011 schedule for the Teachers Institute on Wireless Technology (TI) workshop.
Offered through the ARRL's Education & Technology Program, the Teachers Institute is a four-day, expenses paid, in-residence learning opportunity designed for motivated teachers and other school staff who want to learn more about wireless technology and bring that knowledge to their students.
A variety of topics are covered during the TI, including basic wireless technology literacy, electronics, the science of radio, radio astronomy, how to bring space into the classroom, ham radio operation, introduction to microcontrollers and basic robotics. While participants do not need to have an Amateur Radio license to attend the basic TI sessions, one is required for the advanced (TI-2) session.
TI-2 Space is sponsored by the Dayton Amateur Radio Association. The TI-2 Space curriculum focuses on the nuts and bolts of setting up and operating a satellite ground station. This serves as excellent preparation for a scheduled contact with the ISS through the Amateur Radio on the International Space Station (ARISS) program. But it also provides instruction for continued use of satellites and other man made space assets to explore naturally generated signals, space and a variety of topics. Dates of the Institute are July 11-14, 2011. The application deadline is May 15, 2011.
The course will be 4 days: the first half will be setting up and learning to operate the ground station, the second half will be practice making satellite contacts and instruction in using space borne assets in the classroom. Participants will receive all the equipment necessary to set up a basic satellite ground station. They will participate in an antenna building party (an activity they can duplicate back home with their students).
Though participants need not hold an amateur radio license to enroll in all other sessions of the TI, to be considered for a seat in TI-2 Space, participants must possess at least a Technician class license at the time of application. Priority for attending the TI-2 Space session will first be given to teachers who are signed up for an ARISS contact; second, to TI graduate teachers who have completed an ARISS contact; third to TI graduates who want to learn more about bringing space related activities into their classrooms.
This session has a class limit of 8 participants, so apply early! Full information and applications are on-line at: http://www.arrl.org/ti-2-space-in-the-classroom

SB SAT @ AMSAT $ANS-037.07 Codec2 Alpha Release Demonstration
AMSAT News Service Bulletin 037.07 From AMSAT HQ SILVER SPRING, MD. February 6, 2011 To All RADIO AMATEURS BID: $ANS-037.07
Codec2 Alpha Release Demonstration
If you attended the 2010 AMSAT Space Symposium you heard the talk by Bruce Perens, K6BP about the Codec2 Project, the open-source, low-bit rate voice codec that is being led by David Rowe VK5DGR.
Bruce, VE9QRP recently completed an internet bitstream concact with Paul, ZL3IN using an alpha-level release of Codec2. Bruce made a video of the conversation using the actual audio of the digital audio. You are invited to view/listen to the Codec2 dem- onstration at: http://www.youtube.com/watch?v=_k-nhHE6CrI
This demonstration is running at 2500 bps. Bruce wrote, "We're aiming for 2400 bps with Forward Error Correction, it could make satellite voice communication comprise a smaller bandwidth, offer- ing less demanding downlink systems. Because it is open source, the codec could even be implemented in the satellite, perhaps to provide voice-encoded telemetry for a FUNcube-like project of the future."
The Codec2 site is http://www.rowetel.com/blog/?page_id=452
The source files of Bruce's conversation with ZL3IN, and many ancillary Codec2 materials are available on his blog: http://ve9qrp.blogspot.com
