comments below. In case your tracking program cares, these elements, like all
NASA element sets, are equator-based. --K5ZC]

SUBJECT: STS-47 elements for Sep 12 launch

I'm not sure if I already send you this or not.  It's my element set
for a Sep 12 launch with the new post OMS-2 vector that's a couple of
miles higher.

[...and here's a reposting of the STS-47 SAREX fact sheet, in case you missed
it the first time around. --K5ZC]

           Shuttle Amateur Radio Experiment (SAREX) Fact Sheet

                    STS-47    Space Shuttle Endeavour

When:      Mid-September, 1992 for 6 days of 2 meter operations.

Where:     Earth Orbit. Altitude 300 kilometers, with radio coverage of
           latitudes from 70 degrees North to 70 degrees South.

Operators: Dr. Jay Apt N5QWL and Dr. Mamoru Mohri 7L2NJY.
           N5QWL is the flight engineer for STS-47 and will operate the
           shuttle systems during the "night" shift, while 7L2NJY will be
           one of the scientists performing experiments in a laboratory
           in the shuttle's cargo bay during the "day" shift.

Modes:     FM Voice
                VOICE CALL SIGNS: N5QWL and 7L2NJY

           Packet (Beacons giving daily mission activities by N5QWL daily
                if I get a chance, and robot QSOs - successful connects
                will be issued a contact number by the robot)
                PACKET CALL SIGN: W5RRR-1

Frequencies: We will operate split.  PLEASE DO NOT TRANSMIT ON THE
             DOWNLINK FREQUENCY!

        VOICE:   Downlink (shuttle transmits) on 145.55 MHz
                 Uplink (ground transmits) on 144.95, 144.91, 144.97
                         (except over Europe) - we'll listen on those 3
                         frequencies to spread out the pileup a bit.
                 Uplink for Europe only: 144.80, 144.75, 144.70

                 Successful QSOs on voice will be facilitated by using
                 standard international phonetics for your call sign.  We
                 will not answer any stations using non-standard
                 phonetics.  Use your entire call sign - we log with an
                 audio tape recorder.  Do not use our call sign - passes
                 are very short, and we want to work as many folks as
                 possible.

        PACKET:  Downlink (shuttle transmits) on 145.55
                 Uplink (ground transmits) on 144.70 (worldwide)

        If you can, decrease your radio's deviation to 3 KHz (most are
        initially set at 5 KHz) and compensate for the Doppler shift.  If
        you cannot, wait until a minute or 90 seconds after we come over
        your horizon to transmit - that will put you within our IF.  If
        a station transmits without following these suggestions, we just
        hear what sounds like a noisy carrier.  The above applies to both
        voice and packet.


QSL via:   N5QWL, 806 Shorewood Drive, Seabrook, Texas 77586 USA

     Include a self-addressed stamped envelope (SASE).

     Non-US stations include a self addressed envelope with $0.50 of US
     postage affixed or appropriate IRCs.

     Include the Callsign worked, Date, UTC, Mode, and Frequency.
     For packet contacts, include the QSO number issued by the robot.

     SWL QSL's: Include the Callsign heard, Date, UTC, Mode, and
     Frequency.


Information during the mission:
     AMSAT bulletins, Compuserve, Genie, Prodigy, local packet bulletin
     boards, ARRL bulletins, and HF voice from NASA Johnson Space Center
     ARC, Houston, Texas, W5RRR, or NASA Goddard Spaceflight Center ARC,
     Greenbelt, Maryland, WA3NAN, frequencies listed below.

     W5RRR may be found on or near: 7.215, 14.280, 21.360, and 28.400.
     WA3NAN retransmits NASA Select Audio and SAREX bulletins
     simultaneously on or near 3.860, 7.185, 14.295, 21.395, and 28.650.

     The NASA Info BBS at Johnson Space Center, Houston, will also carry
     Keplerian elements and SAREX bulletins.  (713) 483-2500, 1200 baud,
     8-N-1.  At the ENTER NUMBER: prompt, type 62511 <return> and log
     onto the BBS.  The Keps and bulletins will be in the welcome
     message.  Disconnect rapidly to facilitate access by others.

Operations Notes:

     N5QWL will be asleep over most USA passes, and 7L2NJY will be busy
with laboratory duties for most US passes, so try us on packet over the
USA.  Remember, our packet call sign is W5RRR-1.  We'll try to work voice
(1) when we are not otherwise engaged, and (2) at night or when the
ground is cloudy (we are generally busy taking pictures of the Earth
during clear daylight passes).  Our orbit will carry us over the Northern
hemisphere in daylight.

     We plan to work 6 schools on this mission: 2 in the US, 3 in
Australia, and 1 in Europe or Africa.

     We do not plan any orbiter maneuvers after the first 6 hours of the
flight, so orbital elements obtained early in the flight ought to be
pretty good for the entire flight.  If I can get to it, I'll activate the
SAREX about 3 hours into the mission; deactivation will occur at about 6
days, 8 hours after launch.

     The orbiter attitude is planned to be tail down, payload bay south.
The SAREX antenna will be in the right forward window, so most contacts
should have a good antenna pattern from AOS to TCA (time of closest
approach).
