SAREX 15th Anniversary

The liftoff of the STS-9 Space Shuttle mission 15 years ago this past week ushered in a new, pioneering era of Amateur Radio in space. On November 28, 1983, the Space Shuttle Columbia lifted off from Launch Pad 39 with great anticipation, excitement and fanfare from the entire International Amateur Radio community.

On-board this flight was veteran astronaut and Amateur Radio operator Owen Garriott, W5LFL. With him was the first human-operated Amateur Radio station in space, a Motorola 2-meter FM handheld transceiver and a window-mounted antenna. W5LFL also had interface cabling to record the much anticipated in-orbit contacts.

Roy Neal, K6DUE, Chairman of the SAREX Working Group, remembers it well:

"We were given a golden opportunity by NASA. The opportunity to show the world what happens when you marry Amateur Radio and space flight. So we set out to deliver the maximum number of contacts worldwide -- and Owen delivered. He talked with hams from every walk of life, from King Hussein of Jordan, to entire groups of amateurs who had gathered in England, the United States, Germany, Australia and Japan. He delivered contacts that were sparkling in their clarity and outstanding in their content. They gave us the thrill of working the ultimate DX."

Owen's first ham radio contact --with Lance Collister, WA1JXN, (now W7GJ) of Frenchtown, Montana-- opened the door for the general public to talk to an orbiting space crew. Prior to this historic moment, only Mission Control, Presidents, heads of state, and other high-ranking dignitaries were given this opportunity. By the time his ten-day flight was completed, Owen had made 2-way contact with over 300 hams around the globe. W5LFL's flight provided tens of thousands of hams their first opportunity to receive radio signals from an orbiting space vehicle. In addition, many school students participated in mission activities and heard the W5LFL downlink signals live in their classrooms.

Rosalie White, WA1STO, head of the ARRL's Educational Activities Department and a member of the SAREX Working Group stated:

"The first ham in space mission with Owen on-board was not planned to be a school group educational activity -- it was really an opportunity to make amateur radio shine -- however, the tremendous excitement generated by ham radio in space and the interest in linking SAREX with education eventually snowballed into quality educational events."

Since its modest beginnings on STS-9 in 1983, the SAREX payload has become the most 'frequent flyer' payload in the Space Shuttle Program. To date, SAREX has flown on 24 Space Shuttle Missions, about 25% of the entire Shuttle missions flown to date. This feat could not have been accomplished without the support of the NASA Astronaut Office and the volunteer trainers at the NASA Johnson Space Center who work with astronauts to help them become licensed Amateur Radio operators. "So far we have 86 astronauts that have achieved ham radio license status," says Matt Bordelon, KC5BTL, the SAREX Principal Investigator at JSC. "Now," he added, "we're well on the way to flying some very sophisticated hardware in the International Space Station."

The SAREX program has had an opportunity to accomplish a number of pioneering firsts for ham in space and for NASA operations. These include:

** The first uplink and downlink of SSTV pictures on the STS-51F flight in 1985 with Tony England, W0ORE

** The first computer-to-computer radio link (Packet Radio) on the STS-35 flight with Ron Parise, WA4SIR, in 1990

** The first video uplink on the 1991 STS-37 flight with Commander Ken Cameron, KB5AWP, operating the station

** The first round-trip video on STS-56 in 1993 and the first backup communications during a TDRSS satellite outage with the STS-47 mission in 1992

The SAREX Payload is primarily flown as an educational outreach activity. Hundreds of schools have had a pre-scheduled interview with an orbiting crewmember and tens of thousands of students have participated  directly in the hundreds of pre-scheduled contacts. The educational activities that schools have initiated prior to and after a SAREX educational event have spanned the entire spectrum of ideas -- including developing a 'Shuttle Bus', complete with an Amateur Radio 'Mission Control' inside, sponsoring ham radio classes for Students, participating in the joint SAREX/SAFEX antenna test on the STS-55 mission and providing direct uplink/downlink support to other schools as a Telebridge Amateur Radio station.

The launch of the Mir space station in 1986 opened additional U.S.-based ham radio operations in space. Ship-to-ship contacts were accomplished by several U.S. astronauts and Russian cosmonauts using SAREX and the ham radio equipment on Mir. These were accomplished long before NASA and the Russian Space Agency decided on a partnership for the International Space Station. When U.S. astronauts had extended stays on the Mir space station, ham radio was an important component of their day-to-day activities. Through the cooperation and support of the Amateur Radio communities in Russia, Germany and the United States, the U.S. astronauts were granted permission to use the ham gear on Mir. The astronauts used the radio equipment to communicate with hams on the ground, with their friends and family and with SAREX-selected schools. In fact Mike Foale, KB5UAC, who operated on several previous SAREX Shuttle missions (STS-37 and STS-56), used the ham radio station on Mir to communicate the status of Mir and the welfare of the crew after the Spektr module collided with the spacecraft in June 1997.

Since the time of W5LFL's flight 15 years ago, the internationally-based human spaceflight radio community has done many tremendous things both for Amateur Radio and for education. Frank Bauer, KA3HDO, AMSAT-NA Vice President for Human Spaceflight Programs, reflected his sentiments of this historic event:

"I want to take this opportunity to thank and to congratulate the hundreds of volunteers around the world who have taken the dream that was shared by Owen, the ARRL, AMSAT-NA and NASA, and turned it into a reality that has benefited the worldwide community of radio amateurs as well as students in classrooms. Through your efforts, we have Amateur Radio stations that have flown on Space Shuttles and on Mir, and we are on the threshold of installing a permanent Amateur Radio station on ISS".

Frank continued, "On behalf of the SAREX Working Group and as a U.S. delegate to the Amateur Radio on the International Space Station (ARISS) program, I look forward to the continued cooperation of all the international partners that comprise ARISS -- as we jointly forge a new, exciting future for Amateur Radio in space".

To all those who have made SAREX such a tremendous success and to Owen Garriott, W5LFL, who helped start it all -- thank you and congratulations!

[ANS thanks Frank Bauer, KA3HDO, AMSAT-NA Vice President/Human Spaceflight Programs, the SAREX Working Group, NASA, and the ARRL for making a wonderful dream come true for many Amateur Radio operators the world over]

General Access for TMSAT-1

Good news! Chris Jackson, G7UPN / ZL2TPO, tells ANS that TMSAT-1 (TO-31) is now open for general access by Amateur Radio operators worldwide. Chris tells ANS that TMSAT commissioning has been completed and it shows that most of the spacecraft systems are operating correctly. Normal access will allow operators to use the store and forward communications on the spacecraft, and also download the high-resolution multispectral images.

G7UPN hopes that Amateur Radio operators will take advantage of the high-resolution multispectral images available from TO-31 "and keep other traffic to a minimum." According to Chris, "due to current limitations with on-board memory, images will only be available on the satellite for a few days after they are taken. If other files (especially large files) are uploaded to the satellite, this will ultimately increase the amount of time taken to download images and they may therefore be deleted before they are completed."

During the commissioning process, a problem with the downlink transmitter was found, and G7UPN tells ANS that "unfortunately, the transmitter is still causing some problems and operation is not currently available over most areas." Amateurs in Europe and Asia will find the downlink 'on' most of the time, and it will remain on for between 15 and 30 minutes at a time. In the coming weeks the transmitter will be switched on over more areas and allow much wider access TO-31.

"Testing will continue," says Chris, "and during some of these tests, access may be limited to command stations only. If at any time the BBS is in a 'SHUT' mode as displayed in WiSP (or any of the digital programs), please do not attempt to access the satellite as it may delay any command string that is underway."

27th Annual SKN on OSCAR

AMSAT's Ray Soifer, W2RS, tells ANS that ham operators the world over are "most cordially invited" to join in the AMSAT 27th Annual Straight Key Night (SKN) sponsored by AMSAT-North America for Amateur Radio satellite enthusiasts worldwide.

According to W2RS, it's entirely unofficial; there are no rules, no scoring and best of all -- no need to send in a log. The only thing that satellite operators need to do is call CQ-SKN in the CW passband segment of any OSCAR satellite from 0000 to 2359 UTC on January 1, 1999, (or) answer a CQ-SKN call from another station. OSCAR Zero (EME) contacts also count.

Of course, all SKN operating must be done with a straight hand key.

In addition, participating sat-ops are encouraged to nominate someone they worked for recognition as having the 'best fist'. To send such a nomination, please address it via e-mail to:

w2rs@amsat.org (or) via packet radio to:

W2RS@WA2SNA or W2RS@GB7HSN

Nominations will also be accepted via the W2RS callbook address.

Those nominated will be featured in a future W2RS bulletin to be sent to all the Amateur Radio publications and posted via ANS to packet radio systems and the Internet -- in early February 1999.

RS-18/Sputnik 41

Downlink 145.812 MHz FM

Russian cosmonauts successfully launched RS-18/Sputnik 41 on November 10, 1998, during a spacewalk from the Mir space station. The spacecraft is just under 8 inches in diameter, weighs almost 9 pounds and carries a 200-mW transmitter. RS-18 has no solar cells and its expected operational lifetime is approximately 30 days.

Recent RS-18 reception reports have been received from KC8CMQ, KC8CUC, KB5SZO, N7UIE, NU3S, KE6ZGP, W2RS, KE4TIE, TA2NC, 9H1IF, KH2PM, KD9KC, SP6QKP, NU0C and EA4EKH.

Recent RS-18 reception reports have been received from Kevin, AC5DK, who copied RS-18 after finishing a clean sweep in the November SS contest! Other reports have been received from SP6QKP, F6AGR, KH2PM, KC7RKH/4, and KD5DAY.

Hank, N1LTV, tells ANS he has put together a 'Sputnik-41 Telemetry Assistant' software program that may be of help to those monitoring RS-18. The software tacks the internal temperature of the spacecraft, recording the report in Fahrenheit and/or Celsius rounded to a tenth of a degree. The free program is available for downloading at:

AO-10

Uplink 435.030 to 435.180 MHz CW/LSB
Downlink 145.975 to 145.825 MHz CW/USB
Beacon 145.810 MHz (unmodulated carrier)
Operational.

AO-10 continues to function well with the exception of the periodic deep QSB, which can be partially eliminated by switching antenna polarization. Strong signals have been heard even at apogee. Also note that AO-10's apogee is approaching its most northern point (ArgP = 270). From there the apogee will begin its slow migration southward.

Peter, VE7AHX, tells ANS of a "spectacular QSO" on AO-10 -- a roundtable with KC2PJX, N6PAA, N2YAC and K6YK -- with the satellite below the horizon at times. Signals were running S-9 or better, with KC2CJX receiving the bird "as loud as his local repeater."

Waldis, VK1WJ, recently worked Bill, VU2MKP, with 5X5 signals each way. Andy, GD0TEP, worked IK5QLO, SP6LB and DJ5MN recently (all on CW). Hardy, DC8TS, reports 9M8TG and YB0ARA/9 have been active on AO-10. SP6QKP has also been active, as has Raul, EA4EKH, who reports working Jussi, OH5LK.

W4SM tells ANS that he has, using ranging software (and hardware) developed by James Miller, G3RUH, recently made ranging measurements on AO-10 for the last week and have fed these measurements into an algorithm which generates modified Keplerian elements from a "seed" set of elements. The Keplerian elements generated appear to be accurate within 16-25 km.

Note: This element set may have to be entered by hand or cut and pasted line by line into a tracking program, rather than automatically extracted. They are not in the complete AMSAT format, orbit# (Epoch rev), Element set#, and Checksum are not included.

AO-27

Uplink 145.850 MHz FM
Downlink: 436.792 MHz FM
Operational.

The TEPR settings of AO-27 were recently reset by Chuck, KM4NZ. The new settings now reflect the Earth's position during the northern fall/winter season, and should provide more satellite 'on' time for AO-27 during each pass.

Scott, VE6ITV, tells ANS that "AO-27 is super with the new TEPR settings." Chris, KH2PM, recently made his first QSO via AO-27. Mike, KF4FDJ, regularly works the satellite with his Yaesu handheld. Al, XE2YVW is planning to activate several new grid squares during an upcoming trip, including DK79, DL81 and DK89.

Downlink 435.910 MHz FM 9600 baud BPSK
Not operational, the satellite is in JA (voice) mode.

Kazu, JJ1WTK, tells ANS that the FO-29 Command Team has released the following announcement concerning FO-29 status:

The present JA mode of operation will continue to investigate the frequency of bit errors in the on-board-computer. Reports from Amateurs on the value of channel 2A are appreciated. The position of 2A is the fifth item after 'HI HI' in CW telemetry. The normal value is '00'. Reports should be sent to lab@jarl.or.jp.

FO-29 is still in 'full sun illumination'; this should end in December.

The on-board-computer (OBC) did accept commands from ground control before full illumination began. The FO-29 Command Team says digital (JD) mode operation may be available in December. Digi-talker operation is also being planned. The next announcement is expected November 20th.

[ANS thanks Kazu Sakamoto, JJ1WTK, for this report.]

KITSAT KO-23

Uplink 145.850, 145.900 MHz FM
Downlink 435.175 MHz FM, 9600 Baud FSK
Operational.

Richard, G3RWL, reports recent trouble uploading to KO-23. ANS also received similar reports from WA4SCA, G8UFN and N1QQV. Alan, WA4SCA, also reported that "KO-23 seems to be back to normal, but the downlink is up about 6 kHz from where it has been."

[ANS thanks Jim Weisenberger, AA7KC, and G3RWL, WA4SCA, G8UFN and N1QQV for KO-23 reports]

KO-25

OSCAR-11

Downlink 145.825 MHz FM, 1200 baud PSK
Beacon 2401.500 MHz
Operational.

Clive, G3CWV, reports an uneventful month for OSCAR-11. Telemetry has been nominal.

The mode-S beacon is on, transmitting an unmodulated carrier, however telemetry indicates that it has partially failed, delivering half power. This beacon is a useful test source for those testing mode-S converters prior to the launch of P3D. The 435.025 MHz beacon is normally off.

Two new WOD software packages have recently added to the Oscar 11 web site. The first package enables various WOD channels to be compared with the solar eclipse status of the satellite. The second package compares measured and calculated magnetic fields encountered by Oscar 11. Both packages are of an advanced nature, users will need experience using the other WOD packages on the web site and a spreadsheet program.

TMSAT-1 TO-31

Downlink 436.923 MHz

TMSAT-1 is now open for general access by Amateur Radio operators worldwide. TMSAT commissioning has been completed and shows that most of the spacecraft systems are operating correctly. Normal access will allow operators to use the store and forward communications on the spacecraft and also download the high-resolution multispectral images.

It is hoped Amateur Radio operators will take advantage of the high-resolution multispectral images available from TO-31 and keep other traffic to a minimum. Due to current limitations with on-board memory, images will only be available on the satellite for a few days after they are taken.

Testing will continue and access may be limited to command stations only. If at any time the BBS is in a 'SHUT' mode as displayed in WiSP (or any of the digital programs), do not attempt to access the satellite as it may delay any command string that is underway.

The TechSat-1B micro-satellite was successfully launched from the Russian Baikonur Cosmodrome on July 10, 1998. The satellite is expected to be available for general amateur use in the future.

The satellite does not have a continuous beacon, but does transmit a 9600-baud burst every 30 seconds (for about 3 seconds in length), currently on 435.225 MHz.

The TechSat team has also constructed a home page about the TechSat bird, and promise they will add more information in the next few weeks. To view the site, point your web browser to:
