Richard, G3RWL reported that the file server on LUSAT-OSCAR-19 has still not been made available possibly due to a power struggle within AMSAT-LU. The packet mailbox on FUJI-OSCAR-20 is gone forever due to a failed computer. The analog (Mode JA) transponder is available, however. Two uplink channels on KITSAT-OSCAR-25 have failed. This causes uplink contention on the remaining uplinks. ITAMSAT-OSCAR-26 controllers have not had enough time to fix the problems with IO-26 since it's on-board computer crashed back in May. And POSAT-OSCAR-28 apparently came and went, unlikely to ever be seen again. * AMSAT-OSCAR-10 NEWS * ======================= Several stations have reported that AO-10's downlink is FMing. Downlink frequency instability is due to low and varying battery voltages. This is a dangerous condition, and it is important that all ground stations curtail transponder operations when the frequency of the downlink becomes unstable to reduce the drain on AO-10's batteries and to allow them to recharge. * STS-68 NEWS * =============== Launch of Space Shuttle Endeavour was aborted just seconds before liftoff on 18-Aug-94. The primary payload for this mission is the Space Radar Laboratory, part of a comprehensive effort under NASA's Mission to Planet Earth program, to understand how the Earth's environment is changing. * FEEDBACK/INPUT WELCOMED * =========================== Mail to SpaceNews should be directed to the editor (John, KD2BD) via any of the following paths: FAX : 1-908-747-7107 PACKET : KD2BD @ N2KZH.NJ.USA.NA INTERNET : kd2bd@ka2qhd.de.com -or- kd2bd@amsat.org SATELLITE : AMSAT-OSCAR-16 MAIL : John A.

Andy reports there is a lot of RS activity from stations in Germany, England, Italy, and Switzerland. Activity from the Commonwealth of Independent States is low, although there are some active stations in the Leningrad region, Siberia, and Moscow. The ROBOTs (autotransponders) are functioning well on the satellites. Andy reminds us of a special channel on RS-10 that operates on an uplink frequency of 145.850 MHz and downlink of 29.350 MHz. The RS-14/AO-21 CW beacon (145.822 MHz) can sometimes be heard coming through RS-10's ROBOT, which has a downlink on 29.403 MHz. No word has been received regarding the launch of RS-15. At the RS Command Station, RS3A, Andy operates through RS-10 only. The station consists of a 100-watt uplink transmitter that feeds a groundplane antenna. The downlink receiver is an R250M2 and contains 20 tubes. It is also very heavy and weighs about 95 kilograms. A 3 element yagi antenna is used for receiving RS-10 downlinks at the RS3A Command Station. QSL cards for ROBOT contacts are available through DF4XW or Andrey Mironov, ul.V-Voloshinoj, d.11, kv.72, station Perlovskay, 141014, Moscow region, Russia, C.I.S. [Info via Andy, RK3KPK] * ENCRYPTION OF METEOSAT HRI TRANSMISSIONS * ============================================ The following information was taken from the EUMETSAT Newsletter, Darmstadt, Germany. Starting in 1995, HRI data will be transmitted in encrypted form. Test transmissions have already been scheduled this year. This service will continue with the new High Rate Image Transmission (HRIT) to be introduced with the Meteosat Second Generation, scheduled for launch in the year 2000. HRIT format will provide considerable enhancements to the information available from current Meteosat HRI transmissions. For PDUS users to be able to use encrypted data they will need to obtain a decryption facility for use within their particular receiving station. Decryption will require a Meteosat Key Unit (MKU) at a cost of 700 ECU. The apparent reason for the introduction of data encryption for meteorological data is its use by commercial enterprises, who do not contribute to the cost of data collection, but charge customers for the provided services. There are no plans to encrypt analogue WEFAX transmissions of Meteosat data, so reception via SDUS (Secondary Data User Stations will be unaffected. By the time of the launch of the Meteosat Second Generation (MSG) satellite in the year 2000, a new and improved integrated digital data transmission system known as LRIT (Low Rate Image Transmission) will replace the current analogue WEFAX data formats and MDD. This system will extend much of the functionality and flexibility which are only available currently to users of PDUS equipment. Selected sections of the LRIT data (e.g. MDD) already subject to encryption, will continue to be distributed on a restricted basis.

The satellite ground station consists of a Yaesu FT-726R tribander (2m/70cm/6m), a Cushcraft AOP-1 system (an A144-20T 146MHz Twist antenna and a 416TB 435 MHz Twist antenna), a Kenpro KR-400RC azimuth and KR-500 elevation rotors, a Tokyo Hy-Power HL-120U 70cm amplifier, and a GaAsFET 2m preamp. Uplink power is around 25 watts. The low uplink power is due to a defective 70-cm power amplifer and a replacement for it as well as a broken Yaesu MH-1 mobile microphone are sought. Anyone who can help is asked to contact Rick, BZ1QL at any of the addresses listed below. TUARC would like to thank CRSA, the Chinese Radio Sports Association, as well as Sam N3NFK, Bill KA3HPQ, Jackie KA3HPP, Chris AA2MJ, Allan WA2JVI, Presley N5VGC, Max G0PBZ, Rick N6NR and all of the people who have been concerned about TUARC operations.
