SB SAT @ AMSAT $ANS-058.01 UO-14 IN FM MODE AMSAT NEWS SERVICE BULLETIN 058.01 FROM AMSAT HQ SILVER SPRING, MD, FEBRUARY 27, 2000 TO ALL RADIO AMATEURS BID: $ANS-058.01 The latest ARRL Letter reports UO-14 is proving that you can 'teach an old bird new tricks'. The venerable British satellite recently was switched to Amateur Radio operation -- in a FM repeater mode much like AO-27. Chris Jackson, G7UPN / ZL2TPO reported on the AMSAT bulletin board that UO-14 --launched in January 1990-- spent its first 18 months in orbit operating as a store-and-forward satellite. It was then switched for use by Volunteers in Technical Assistance, who used it for medical messaging into Africa. "Since the computer which is used for store-and-forward communications is no longer able to perform that task, UO-14 is no longer usable in this mode," reported G7UPN. "It is, however, possible to use the satellite as a single-channel FM voice repeater, and I have configured the satellite to do this." The satellite works as a FM bent-pipe repeater in full duplex. The uplink is 145.975 MHz and the downlink is 435.070 MHz. Houston AMSAT Coordinator Bruce Paige, KK5DO, says no more than 5-watts is required to make a contact with UO-14, and some have made it with much less. "Cool satellite!" was the reaction of W1AW Station Manager Joe Carcia, NJ1Q. ANS Principle Satellite Investigator Mike Seguin, N1JEZ, told ANS "it's nice to have an FM bird around at night." Operation is also reported to be heavy over other parts of the globe in addition to North America. Both VK3JT and G7NFO reported several contacts via UO-14.

The equipment will be installed as part of the initial ARISS effort on the International Space Station. The training session was conducted at the Gagarin Cosmonaut Training Center in Russia. As part of the ARISS training effort, NASA's Matt Bordelon, KC5BTL, has prepared a consolidated schedule for training in the United States and Russia that will include familiarization with equipment, packet theory and hands-on simulation. The ARRL reports that the training will focus on general principles of ham radio as well as preparations to use station equipment-operating modes, including software. Bordelon has held an initial training session with astronauts and cosmonauts that provided exposure to the actual hardware. Other training has included information required to obtain an Amateur Radio license. The first ISS crew will include Bill Shepherd, KD5GSL and Sergei Krikalev, U5MIR.

Congratulations from ANS! -NN0DJ ** The Canadian special event call sign VC4X has been assigned for use through March 26, 2000 -- to commemorate the 50th anniversary of the 1950 Winnipeg Flood. -Derrick, VE4VV ** This year could be one of the worst for solar storms -- surges of charged particles that knock out satellites, power grids and even garage door openers. No one can predict which month or week will be worst, but the sun is at the height of its 11-year cycle of storms, which means the Earth can expect several barrages of excess charged particles. -Reuters ** The Galileo spacecraft made its third and closest flyby of Jupiter's volcanically active moon Io. The spacecraft passed only 199 kilometers above Io's surface. Although battered by Jupiter's strong radiation, Galileo continues to provide useful imagery and other data, now operating under its second mission extension. -S&T ** Two Vermont hams, Bob, N1MEZ, and Lloyd, W1CX, have recently departed for PJ8 land, vacationing for the next two weeks. They have a tripod mounted VHF/UHF beam antenna and a pair of HT's with receive preamp, and will attempt to operate AO-27 and possibly UO-14. Operation may also take place on RS-13 (SSB) and RS-15 (CW). The grid should be FK88. -Mike, N1JEZ ** Over the past six months, the Southern Hemisphere of Mars has passed through spring and into summer. Spring started in early August 1999 and summer arrived toward the end of December 1999. On Earth, we are about to observe our first leap day with a year ending in 00 since the year 1600, nine years before Galileo used his first telescope! -S&T ** The restructuring of Amateur Radio licensing in Israel earlier this month brought an extension of frequency privileges for some license classes. The code-free Grade D license has had band access extended to 50 MHz, 1.2 GHz and 5.6 GHz. The Grade A license now has access from 2.4 - 2.45 GHz and 5.275 - 5.875 GHz. -AR Newsline ** Some North American doorstep astronomy -- the brightest star nearly straight overhead as twilight fades is Capella. The brightest light in the west-southwest is Jupiter and the brightest in the south-southeast is Sirius. Sirius appears so bright because it's very close as stars go, only 8.6 light-years away, and it really is bright, putting out 22 times as much light as our Sun. -S&T --ANS BULLETIN END--- /EX SB SAT @ AMSAT $ANS-058.05 WEEKLY SATELLITE REPORT PART 1 AMSAT NEWS SERVICE BULLETIN 058.05 FROM AMSAT HQ SILVER SPRING, MD, FEBRUARY 27, 2000 TO ALL RADIO AMATEURS BT BID: $ANS-058.05 RADIO SPORT RS-13 Uplink 21.260 to 21.300 MHz CW/SSB Uplink 145.960 to 146.000 MHz CW/SSB Downlink 29.460 to 29.500 MHz CW/SSB Downlink 145.960 to 146.000 MHz CW/SSB Beacon 29.458 MHz Robot Uplink 145.840 MHz Robot Downlink 29.504 MHz Operational, in mode-KA with a 10-meter downlink and a 15-meter and 2-meter uplink.

Chris Jackson, G7UPN, reports to ANS that UO-22 has now entered full sunlight and the temperatures have increased considerably. Controllers have turned the satellite upside down to point the critical systems to cold space. This has reduced the temperature on various systems (such as the batteries) by between 5 and 10 degrees. The unfortunate by-product of this is that the downlink is now quite weak. The satellite will remain in full sunlight until late March, when controllers will turn it back 'over' again. According to G7UPN "over the next few years this situation will become worse as the no eclipse periods become longer." Only the 145.900 MHz receiver is usable for communications at the moment.
