It is available for unlimited distribution. * STS-35 NEWS * =============== The launch of STS-35 has been delayed at least until 31-May-90 due to a Shuttle hardware problem. Here is the expected operating schedule for unattended SAREX operations by Ron Parise (WA4SIR): Mission Elapsed Time (D/HH:MM) Start End ========+======== 0/22:00 - 1/10:20 1/21:15 - 2/08:35 2/20:00 - 3/07:55 3/19:00 - 4/06:40 4/18:30 - 5/05:45 5/17:20 - 6/05:50 6/17:40 - 7/05:35 7/17:45 - 8/04:45 Listed below are the frequencies presently intended to be used by SAREX for both packet and voice. Note, that in no case is "simplex" operation indicated. DO NOT CALL WA4SIR ON THE SAME FREQUENCY YOU HEAR HIM!! Shuttle Accompanying Offset Transmit Freq. Shuttle Receive Freqs. Designation Group 1 145.55 MHz 144.95 MHz Primary 145.55 MHz 144.91 MHz Secondary No. 1 145.55 MHz 144.97 MHz Secondary No. 2 Group 2 145.51 MHz 144.91 MHz Primary 145.51 MHz 144.93 MHz Secondary No. 1 145.51 MHz 144.99 MHz Secondary No. 2 Group 3 145.59 MHz 144.99 MHz Primary 145.59 MHz 144.95 MHz Secondary No. 1 Group 4 145.55 MHz 144.95 MHz Primary 145.55 MHz 144.70 MHz Secondary No. 1 145.55 MHz 144.75 MHz Secondary No. 2 145.55 MHz 144.80 MHz Secondary No. 3 145.55 MHz 144.85 MHz Secondary No. 4 The 145.55/144.95 combination is in both Groups 1 and 4 because alternate uplink frequencies from Group 1 would be used over North and South America while those from Group 4 would generally be used in other parts of the world, such as Europe and Africa. Dissemination of Shuttle information to those participating in SAREX, as well as all interested amateurs will be via a system of key stations, particularly WA3NAN, at Goddard in Greenbelt, MD, W5RRR, at the Johnson Space Center in Houston, and W6VIO at the Jet Propulsion Lab, in Pasadena, California. These stations, and others, will operate on HF and VHF 24 hours a day carrying official NASA supplied voice communication between Mission Control in Houston and the Shuttle crew. To further provide information specific to SAREX communication opportunities and related information, bulletins originated by amateurs stationed at the Johnson Space Center will be fed via a computer network to these stations and others including W1AW. The SAREX Metabeacon may also be used for announcements. It is planned the frequencies listed below will be used for this service. The selection of frequencies will be made depending on HF propagation conditions during the mission. Station Approx. Nominal Frequencies in MHz QTH (+/- QRM) WA3NAN Wash. DC 3.860, 7.185, 14.295, 21.395, 28.650. 147.45 (FM) W5RRR Houston 3.850, 7.227, 14.280, 21.350, 28.495, 146.64 (FM) W6VIO L.A. 3.840, 21.280, 224.04 (FM) W6FXN L.A. 145.46 (FM) All are SSB using the sideband normally used on the band unless otherwise noted. * FEEDBACK WELCOMED * ===================== Feedback regarding SpaceNews can be directed to the editor (John) via any of the following paths: UUCP : ...uunet!masscomp!ocpt!tsdiag!ka2qhd!kd2bd AX.25 : KD2BD @ NN2Z.NJ.USA.NA MAIL : John A.
