SB SPACE @ ARL $ARLS011 ARLS011 Shuttle Astronauts On-The-Air ZCZC AS90 QST de W1AW Space Bulletin 011 ARLS011 From ARRL Headquarters Newington, CT July 14, 1995 To all radio amateurs SB SPACE ARL ARLS011 ARLS011 Shuttle Astronauts On-The-Air NASA astronauts successfully setup the Amateur Radio equipment aboard the Space Shuttle Discovery on Friday morning. During a test pass, volunteers at the Johnson Space Center Amateur Radio Club station, W5RRR, made contact with the crew as the shuttle orbited over Houston, Texas. Astronaut Don Thomas, KC5FVF said ''Tell everyone hello and thanks to all of the SAREX volunteers, who are doing really great work.'' Don began calling CQ right after the test pass and began working other stations. The crew may make random contacts with many amateurs throughout this mission, which ends on July 21. The educational nature of these contacts makes this activity exciting for amateurs and school children around the world. To avoid causing interference to other stations, SAREX participants should operate only when the shuttle is within range and the astronauts are on-the-air. Non-participants are asked to be patient, as shuttle passes are short and usually occur only a few times each day. The following frequencies can be used to make contact with the shuttle astronauts. The crew will use separate receive and transmit frequencies. The worldwide FM voice downlink is 145.55 MHz. Please do not transmit on the shuttle's downlink frequency. The downlink is your receiving frequency. The uplink is your transmitting frequency. The voice uplink frequencies are 144.91, 144.93, 144.95, 144.97, and 144.99 MHz. In Europe, the uplink frequencies are 144.70, 144.75, and 144.80 MHz. Look for Don, KC5FVF and Mission Specialist Nancy Sherlock Curie, KC5OZX. The crew may also operate packet in an ''unattended'' mode, allowing amateurs to make contacts with the shuttle's ROBOT station when the crew is working or sleeping. The FM packet downlink frequency is 145.55 MHz. The packet uplink frequency is 144.49 MHz. The ROBOT call sign is W5RRR-1. Send reports and QSLs to ARRL EAD, STS-70 QSL, 225 Main Street, Newington, CT 06111-1494, USA. Include the following information in your QSL or report: mission STS-70, date, time in UTC, frequency and mode (FM voice or packet). In addition, you must also include a SASE using a large, business-sized envelope if you wish to receive a card. The Sterling Park Amateur Radio Club in Sterling, VA has generously volunteered to manage the cards for this mission. Thanks to the SAREX Working Group for the preceding information. The Shuttle Amateur Radio EXperiment is sponsored by AMSAT, ARRL and NASA. NNNN /EX
