* STS-35 NEWS *
===============
The launch of STS-35 has been delayed at least until 31-May-90 due to a
Shuttle hardware problem.

Here is the expected operating schedule for unattended SAREX operations by
Ron Parise (WA4SIR):

Mission Elapsed Time
     (D/HH:MM)

 Start      End
========+========
0/22:00 - 1/10:20
1/21:15 - 2/08:35
2/20:00 - 3/07:55
3/19:00 - 4/06:40
4/18:30 - 5/05:45
5/17:20 - 6/05:50
6/17:40 - 7/05:35
7/17:45 - 8/04:45

Listed below are the frequencies presently intended to be used by SAREX for
both packet and voice.  Note, that in no case is "simplex" operation
indicated.  DO NOT CALL WA4SIR ON THE SAME FREQUENCY YOU HEAR HIM!!


            Shuttle             Accompanying           Offset
         Transmit Freq.     Shuttle Receive Freqs.   Designation

Group 1    145.55 MHz            144.95 MHz          Primary
           145.55 MHz            144.91 MHz          Secondary No. 1
           145.55 MHz            144.97 MHz          Secondary No. 2

Group 2    145.51 MHz            144.91 MHz          Primary
           145.51 MHz            144.93 MHz          Secondary No. 1
           145.51 MHz            144.99 MHz          Secondary No. 2

Group 3    145.59 MHz            144.99 MHz          Primary
           145.59 MHz            144.95 MHz          Secondary No. 1

Group 4    145.55 MHz            144.95 MHz          Primary
           145.55 MHz            144.70 MHz          Secondary No. 1
           145.55 MHz            144.75 MHz          Secondary No. 2
           145.55 MHz            144.80 MHz          Secondary No. 3
           145.55 MHz            144.85 MHz          Secondary No. 4

The 145.55/144.95 combination is in both Groups 1 and 4 because alternate
uplink frequencies from Group 1 would be used over North and South America
while those from Group 4 would generally be used in other parts of the world,
such as Europe and Africa.

Dissemination of Shuttle information to those participating in SAREX, as well
as all interested amateurs will be via a system of key stations, particularly
WA3NAN, at Goddard in Greenbelt, MD, W5RRR, at the Johnson Space Center in
Houston, and W6VIO at the Jet Propulsion Lab, in Pasadena, California.
These stations, and others, will operate on HF and VHF 24 hours a day carrying
official NASA supplied voice communication between Mission Control in Houston
and the Shuttle crew.  To further provide information specific to SAREX
communication opportunities and related information, bulletins originated by
amateurs stationed at the Johnson Space Center will be fed via a computer
network to these stations and others including W1AW.  The SAREX Metabeacon may
also be used for announcements.  It is planned the frequencies listed below
will be used for this service.  The selection of frequencies will be made
depending on HF propagation conditions during the mission.

Station  Approx.        Nominal Frequencies in MHz
           QTH                 (+/- QRM)

WA3NAN   Wash. DC  3.860, 7.185, 14.295, 21.395, 28.650. 147.45 (FM)
W5RRR    Houston   3.850, 7.227, 14.280, 21.350, 28.495, 146.64 (FM)
W6VIO    L.A.      3.840, 21.280, 224.04 (FM)
W6FXN    L.A.      145.46 (FM)

All are SSB using the sideband normally used on the band unless otherwise
noted.
