2.4 GHz downconverters for sale
by K & R Yoksh 15 Jun '08

15 Jun '08

Hi, I have two more S-band gear for sale. Pictures are available at the URL under each item. Contact me directly (not via the BB) at k0kn at amsat dot org. * California Amplifier brand, model # 130003, consists of a downconverter and integrated linear patch antenna. Can be mounted for either vertical or horizontal polarization. Includes screw-on set of disc director elements. 144 MHz IF (2400 MHz = 143.55 MHz). $45 + s&h http://www.qsl.net/k0kn/130003.jpg * Same as above, but with 122 MHz IF instead (2400 MHz = 122.019 MHz) $35 + s&h http://www.qsl.net/k0kn/130003.jpg These converters are capable of hearing AO-51, and can even be used as a makeshift dish feed. I worked AO-40 this way for a time! These should attach fairly easily to an Arrow type antenna for mode V/s on AO-51. I also have two Cal Amp 31732 "dead ducks" that did work at one point in the AO-40 days, but have since stopped working. Can be used for parts, a signal source, or worst case, a weatherproof enclosure with one N female connector, and two F female connectors. Paint peeling on one lid. $5 each http://www.qsl.net/k0kn/31732.jpg I had planned to follow the lead of GM1SXX, but have not yet found time to convert these ducks. See his article: "Project Duckling - or - Uses for Dead Drakes," The AMSAT Journal, May/Jun 2001, pp. 8-9. 73, Kyle Yoksh K0KN Olathe, Kansas

AO-51 schedule note
by Andrew Glasbrenner 15 Jun '08

15 Jun '08

There are presently two places people can look for AO-51 mode info, the graphic schedule at http://www.amsat.org/amsat-new/echo/ControlTeam.php and the full text schedule at http://www.amsat.org/amsat-new/echo/CTNews.php . If you'll note the graphic schedule shows no uplink to AO-51 on the 21st. This is only partially correct. On 6/21 we will be running AO-51 with an alternate uplink for the ARRL Kid's Day event, and QSOs should be limited to Kid's Day activities. This is posted in the text schedule, but there is no way to post that important information in the graphic schedule. The intent here is to keep the repeater free and clear for the Kid's Day participants, and showing the uplink as off is the only way to do that in the current graphic schedule design. If you see this type of entry in the future, please head over to the text schedule at http://www.amsat.org/amsat-new/echo/CTNews.php to get the full story. The mode change today was moved up ~12 hours simply because I want to have dinner with my gravely ill father on Father's Day, and the other command stations are not available. Again, I apologize if this has caused anyone any inconvenience. Don't shoot me for trying to keep the users informed please. 73, Drew KO4MA AMSAT-NA VP Ops

June 15, 2008 To All RADIO AMATEURS BID: $ANS-166.03 Santa Clara University students invite amateur radio operators worldwide to participate with them by receiving beacon signals from PreSat and NanoSail-D, two pioneering cubesat missions that will launch from the Reagan Test Site (Omelek Island, Kwajalein Atoll, Republic of Marshall Islands) on June 23, 2008 at about 7:00 pm PDT. Both spacecraft will go into Low Earth Orbit as secondary payloads aboard a SpaceX Falcon-1 launch vehicle into a 685x330 km, 9 degree inclination orbit. PreSat is a 10 x 10 x 30 cm. spacecraft, operating at 437.318 MHz FM, will send an AX.25 packet every 5 seconds. The mission will evaluate the performance of a generic biofluidic sample management and handling system for future advanced in situ spaceborne biology experiments. NanoSail-D is a 10 x 10x 30 cm. spacecraft, operating at 437.269 MHz FM, sending an AX.25 packet every 10 seconds, will deploy a solar sail that also will be used as a drag sail to demonstrate orbital debris mitigation technology. Amateur radio operators are encouraged to submit received beacon packets through the mission websites in order to receive a web-based QSL card: PreSat - http://www.presat.org NanoSail-D - http://www.nanosaild.org [ANS thanks Mike Miller, KE7EGC for the above information] /EX SB SAT @ AMSAT $ANS-166.04 AO-51 Operating Mode Announcement for Field Day AMSAT News Service Bulletin 166.04 >From AMSAT HQ SILVER SPRING, MD.

June 15, 2008 To All RADIO AMATEURS BID: $ANS-166.06 Drew KO4MA, AMSAT-NA Vice-President of Operations gave an update of AO-16's on-going malfunctions and troubleshooting. Drew reported, "AO-16 continues to spontaneously shut off. We suspect it is a watchdog timer that is malfunctioning, and that it is tempera- ture related." The resets on the satellite began shortly after AO-16 re-entered periods of eclipses after a long period of full sun. Mark, N8MH, and Drew have, at various times, re-commanded the bird on. It will stay on for anywhere from just a few seconds to a few minutes. They also experimented with doing the reset operation automatically, with not much success. Drew summarizes, "The current plan is to wait a little bit until the eclipses start getting shorter, the overall temperature of the satellite rises some, and see if the frequency of the resets goes down enough to make some sort of day-to-day operation feasible again." [ANS thanks Drew, KO4MA for the above information] /EX SB SAT @ AMSAT $ANS-166.07 ARISS Status Report for the Week of June 9, 2008 AMSAT News Service Bulletin 166.07 >From AMSAT HQ SILVER SPRING, MD. June 15, 2008 To All RADIO AMATEURS BID: $ANS-166.07 1. School Contact Status Planning continues for ARISS contacts; however, the level of school contacts will drop temporarily due to crew time constraints. On Friday, June 6, a successful ARISS contact took place between Kursk State University in Russia and cosmonauts Sergei Volkov, RU3DIS, and Oleg Kononenko, RN3DX, aboard the ISS. Over three hundred students attended the event. 2. ARRL Article on STS-124 The American Radio Relay League (ARRL) posted a story to its Web site on the STS-124 mission. The article covers ISS flight engineer Greg Chamitoff, KD5PKZ, and mission specialist Akihiko Hoshide, KE5DNI, who flew to the ISS on shuttle Discovery. It also includes information on the new JAXA Kibo laboratory. "Hams Head into Space" may be found at: http://www.arrl.org/news/stories/2008/06/03/10139/?nc=1 The article was also published in the ARRL Letter. See: http://www.arrl.org/arrlletter/08/0606/ 3.
