SB SAT @ AMSAT $ANS-296.01 STS-58 SAREX MISSION INFO HR AMSAT NEWS SERVICE BULLETIN 296.01 FROM AMSAT HQ SILVER SPRING, MD OCTOBER 23, 1993 TO ALL RADIO AMATEURS BT BID: $ANS-296.01 STS-58 Makes A Picture Perfect Lift-Off; SAREX Operations Begin The STS-58 Shuttle Amateur Radio Experiement (SAREX) mission began this past week with a "picture-perfect" lift-off on Monday, 18-OCT-93 at 14:53:10 UTC. On this particular SAREX mission the amateur radio station consists of a 2M FM transceiver and a packet radio TNC. To log the packet station contacts, the SAREX payload also includes a laptop computer. In addition to school contacts, there the packet station will be in operation for unattended "robot" packet contacts. For radio amateurs who make or hear the SAREX station, you are invited to send a QSL card to confirm a packet or voice contact or a SWL report. Send your QSL card to the following address: ARRL, STS-58 QSL 225 Main Street Newington, CT 06111 Please allow for up to 6-10 months for the STS-58 SAREX Mission QSL card to be mailed. Please include with your QSL card all the specific QSO information such as, date, time, mode, frequency, etc. Also, and most importantly, if you wish to receive a QSL card confirming a contact, YOU MUST INCLUDE A SELF-ADDRESS-STAMPED-ENVELOPE (SASE) WITH PROPER POSTAGE! If you do not include a SASE, you will not receive a QSL card. The following information includes the latest keplerian elements and SAREX frequencies.

The Digi-Voice Messages will be transmitted in several languages, including German, Spanish, English, Russian and French. There is currently also a greetings message broadcastet in Czech language. FM-Mode is also in use, and likewise the 1200 Baud AX.25 AFSK telemetry. The telemetry includes bulletins with the current operating schedule. New transmitting modes are scheduled starting end of November, so please stay tuned on AO-21. Look for AO-21's voice message on a downlink freq- uency of 145.987 MHz. [The AMSAT News Service (ANS) would like to thank DB2OS for the information which went into this bulletin item.] /EX SB SAT @ AMSAT $ANS-296.03 AMSAT OPS NET SCHEDULE HR AMSAT NEWS SERVICE BULLETIN 296.03 FROM AMSAT HQ SILVER SPRING, MD OCTOBER 23, 1993 TO ALL RADIO AMATEURS BT BID: $ANS-296.03 Current AMSAT Operations Net Schedule For AO-13 AMSAT Operations Nets are planned for the following times. Mode-B Nets are conducted on AO-13 on a downlink frequency of 145.950 MHz. If, at the start of the OPS Net, the frequency of 145.950 MHz is being used for a QSO, OPS Net enthusiasts are asked to move to the alternate frequency of 145.955 MHz. Date UTC Mode Phs NCS Alt NCS 30-Oct-93 1300 B 62 W5IU WB6LLO 13-Nov-93 1230 B 146 VE2LVC W5IU 28-Nov-93 0230 B 39 WJ9F VE2LVC Any stations with information on current events would be most welcomed. Also, those interested in discussing technical issues or who have questions about any particular aspect of OSCAR statellite operations, are encouraged to join the OPS Nets. In the unlikely event that either the Net Control Station (NCS) or the alternate do not call on frequency, any participant is invited to act as the NCS. ************************************** Slow Scan Television on AO-13 SSTV sessions will be held on immediately after the OPS Nets a downlink on a Mode-B downlink frequency 145.960 MHz. /EX SB SAT @ AMSAT $ANS-296.04 WEEKLY OSCAR STATUS REPORTS HR AMSAT NEWS SERVICE BULLETIN 296.04 FROM AMSAT HQ SILVER SPRING, MD OCTOBER 23, 1993 TO ALL RADIO AMATEURS BT BID: $ANS-296.04 Weekly OSCAR Status Reports: 23-OCT-93 AO-13: Current Transponder Operating Schedule: M QST *** AO-13 TRANSPONDER SCHEDULE *** 1993 Oct 25-Nov 15 Mode-B : MA 0 to MA 130 ! Mode-BS : MA 130 to MA 180 ! Mode-S : MA 180 to MA 205 !<- S transponder; B trsp. is OFF Mode-S : MA 205 to MA 210 !<- S beacon only Mode-BS : MA 210 to MA 226 ! Blon/Blat 210/0 Omnis : MA 240 to MA 80 ! Move to attitude 240/0, Nov 15 Please don't uplink to Mode-B between MA 180-205 as this interferes with Mode-S transponder operations. Reorientation from Attitude 180/0 to 210/0: A magnetorque will be initiated on Orbit #4105 MA 224 [Oct 24 @ 03:48 UTC] and will be executed over 4 perigees, completing on Orbit #4109 MA 32 [Oct 25 @ 17:00 UTC]. The new schedule, as per M-block, will be invoked Orbit #4109 MA 140, and thus that orbit (only) will contain two Mode-S sessions. Continuous up-to-date information about AO-13 operations is always avail- able on the beacons at 145.812 MHz and 2400.646 MHz in CW, RTTY and 400 bps PSK. Also, these bulletins are also posted to INTERNET, ANS bulletins, Packet, PACSATs, as well as many international newsletters. [G3RUH/DB2OS/VK5AGR] AO-16: Operating normally. [WH6I] UO-22: Operating normally. [WH6I] LO-19: Operating normally with new software, that is, the same PB/PG as AO-16/UO-22/KITSATs. [WH6I] KO-23: Up and running. Busy as usual. The images are no longer available. AO-27: Checkout and experimentation continues with the amateur side of AO- 27. For the next several days the 9600 FM downlink will be turned on while the satellite is in view of the command station (N4TPY/N4USI/KA1LM) near Washington, DC. Appropriately equipped amateurs are encouraged to observe the eye pattern of the 9600 baud signal and report results to Mike Wyrick (N4USI) at "wyrick@interf.com" or Steve Greene (KA1LM) at "ka1lm@ amsat.org." Methods of adding de-emphasis to level the amplitude of the data "tones" while receiving the signal directly from the discriminator of the receiver are of particular interest. The downlink frequency for the 9600 data rate is about 4 KHz lower than when the 1200 baud data rate is in use (436.800 MHz). Please report all results to Mike or Steve only. PLEASE DO NOT TRANSMIT TO THE SATELLITE AS YOU MAY INTERFERE WITH ONGOING TESTING AND CHECKOUT! [KB2BD & WD0E ] KO-25: The file system is up and running but not open for uploads. The AMSAT NEWS Service (ANS) is looking for volunteers to contribute weekly OSCAR status reports. If you have a favorite OSCAR which you work on a regular basis and would like to contribute to this bulletin, please send your observations to WD0HHU at his CompuServe address of 70524,2272, on INTERNET at wd0hhu@amsat.org, or to his local packet BBS in the Denver, CO area, WD0HHU @ W0LJF.#NECO.CO.USA.NOAM. Also, if you find that the current set of orbital elements are not generating the correct AOS/LOS times at your QTH, PLEASE INCLUDE THAT INFORMATION AS WELL. The information you provide will be of value to all OSCAR enthusiasts. /EX
