* STS-58 SAREX NEWS *
=====================
The latest in a series of Shuttle Amateur Radio Experiments carried onboard
Space Shuttle "Columbia" has been a great success. The Shuttle astronauts
managed to make scheduled radio contacts with school groups as well as
general contacts with amateur radio operators around the world.
The following packet beacon was sent by Space Shuttle "Columbia" on
25-Oct-93 at 15:14:03 UTC and received by N2NRD:
Thanks for all the great QSO's. KC5AXA, KC5CKM, and I love them.
We're half way through the mission, beginning flight day 8 today.
We are doing human metabolic and cardiovascular experiments in the lab today.
We will also continue with an experiment to quantify the impact human
activity in a space ship on the microgravity environment.
We have had spectacular views of our beautiful home planet.
We hope to bring back a large quantity of pictures.

* MIR OPERATING HINTS *
=======================
This week: Digipeating through MIR
As some have discovered, it is possible to digipeat though the MIR packet
station and use it to connect to other packet stations hundreds of miles
away. Unfortunately, the data throughput is pitifully small. WF1F in
Billerica, Massachusettes ran a test with Joe WA2GSY in New Jersey. Both
stations ran 20 foot 2-meter Yagis with an ERP of approximately 1200 watts.
Late one weekday evening, both stations were fortunate enough to find the
MIR PBBS with no users on frequency. This is an extremely rare condition.
Both stations attempted to directly connect to each other using MIR as a
digipeater, and were successful. Every line of text that was sent to each
other made it through without error. However, because of retries,
acknowledgments, and other packet related overhead, the 120 character per
second transmissions were reduced to approximately 1 character for every
2.5 seconds.
The following short message took 4 minutes and 37 seconds to transfer through
Mir, and required over 132 packet transmissions. There were probably many
more transmissions, but the equipment was not set up to count any packet
collisions at either end.
CONNECTED to WA2GSY VIA R2MIR [04/18/93 00:25:00]
WA2GSY>:PLEASE CONNECT TO WA2GSY-1 FOR MY PMS
WA2GSY>:Hi miles
WF1F>:HI JOE GOT YOU
WA2GSY>:How are you
WA2GSY>:Glad to see you on
WA2GSY>:Whats up
WA2GSY>:Sure is happy to hear you
WF1F>LETS TRY OSCAR 13 OR SSB
WA2GSY>:Did you get the equip fixed
WA2GSY>:*** DISCONNECTED [04/18/93 00:29:37]
Now for the statistics:
Packets from WF1F to WA2GSY through MIR: 31
Packets from WA2GSY to WF1F through MIR: 35
Total time 4:37
Total characters sent by WF1F: 39
Total characters sent by WA2GSY: 110
Throughput would further be reduced if there were ground stations
trying to connect to the PBBS on MIR while other stations used MIR for
digipeating purposes. The bottom line is that digipeating through MIR is
NOT recommended while others are actively connected to the MIR PBBS.
Even under ideal conditions with high ERP, it is not possible to get much
data though MIR acting as a digipeater.
Remember, only 1 station can connect to MIR's PBBS at a time. All others
must wait.

* ITAMSAT-OSCAR-26 NEWS *
=========================
Sunday October 24th 1993 marked a very important day for ITAMSAT-OSCAR 26.
After 28 days in orbit, IO-26 BBS was up and running, and has been accessed
by many amateurs around the world.
The initial reports are very encouraging. Even at this low power setting,
around 250 mW, the PSK signal is crystal clear and decoding is very easy.
LW2DTZ copied the following beacon frames from the satellite:
ITMSAT-1>TIME-1
PHT: uptime is 021/04:11:44. Time is Sun Oct 24 13:42:57 1993

Use standard PB and PG software.
73 de ITAMSAT Command Team
Activity on the BBS has just started, but we have already received many
enthusiatic comments. Ground stations that had accessed the BBS as of
24-Oct-93 included: I0LYL (which we thank for his kind words), I6CGE, IK2OYD,
IK2VOO, IW2EGC, IW4ASO, DL1TV, EA2CLS, OE3EV, ON6UG, WB5FCO and ZS6BMN.
As always, we are waiting for any report from amateurs around the globe!

* VE3ONT EME OPERATION NEWS *
=============================
The Toronto VHF Society plans to continue its EME (Moonbounce) tests
using the 46-meter (150') dish at the Algonquin Provincial Park, Ontario.
Operation will be as follows:
Date VE3ONT Approx.
(UTC) TX Freq RX Freq time (UTC)
Saturday, Nov. 6 432.050 432.050-060 0405-1645
Sunday, Nov. 7 1296.050 1296.050-060 0515-1715
The dish can be lowered to about 9 degrees elevation. This decreases
the operating time by almost an hour at Moon rise and set. It also
limits the ability to work local horizon-only stations.
Equipment: The 432 MHz setup will be significantly better than October's.
The receive problem that gave all signals a 120 Hz buzz has been fixed, and
the antenna will have about 1 dB more antenna gain due to a redesigned feed
helix.
On 1296, VE6ONT will be running about 150 watts output. The feed will be
LHCP/RHCP switchable so they ought to be able to work linear and circular
polarization stations.
VE6ONT anticipates being able to work stations running 50-100 watts to a long
yagi on 432 or 1296. OSCAR-class stations are especially encouraged to try.
Operating suggestions:
Doppler shift will move the apparent VE3ONT frequency a bit. This will
make VE3ONT seem to be a little "off frequency," so tune around. Moon echos
will seem to be somewhat high (in frequency) at Moonrise and low at Moonset.
We will, however, always transmit on .050.
Note that VE6ONT will be operating "split" so please spread out. In the
October operation, some stations were frustrated due to calling VE6ONT on
their own frequency, where they weren't listening. Try to use good split-
frequency HF DXing technique: listen for the stations that VE3ONT is calling
and transmit near their frequency when VE3ONT stands by.
Please avoid duplicate QSOs. The goal is to be "first EME" for as many small
stations as possible. "Calling again to say Hi" hurts small stations'
chances of making a QSO.
VE3ONT will be operating in "contest" mode. They discovered last month that
sequenced operation was not fruitful. They will make every effort to work
small and horizon-only stations but will not accept skeds.
HF Liaison: HF propagation from the park is extremely poor. VE6ONT will try
to check in to the 20-meter (14.345) EME Net during the day and the 75-
meter VHF nets (3.818 & 3.843) at night. Previous attempts to do so were
not successful, so don't expect much on HF.
QSL information: QSL to VE3ONT ('93 Callbook address ONLY!) or to Dennis
Mungham (VE3ASO), R.R. 3, Mountain, Ontario, Canada K0E 1S0. Color photo
QSLs are being prepared.

SB SAREX @ AMSAT $STS-58.025
SAREX Keps & Update: 10/28
Thursday 10/28/93 @ 08:00 UTC
The last school group contact was completed yesterday. The Portsmouth HS
in Portsmouth, New Hampshire had a telebridge contact using stations in
California (Ralph Warner, N6MNN) and Texas (Bob Douglas, W5GEL). The
students asked 5 questions during this bridge contact.
Hams across the U.S. and around the world continue to work the Shuttle
Columbia on both voice and packet. Moreover, the completion of school
group contacts has cleared several school backup passes for possible
general QSO opportunities. While the SAREX Working Group cannot fully
guarantee availability, there is a high probability that the STS-58 crew
will be ready to take general calls over the continental U.S. on these
passes. Two of these "scheduled" passes remain. These include orbit
178 at MET 11 days 1 hour 42 minutes (10/29 at 16:35 UTC) and orbit 192
at MET 11 days 22 hours and 29 minutes (10/30 at 13:22 UTC). Please note
that the astronauts operated voice during yesterday's "scheduled" pass
which occurred on 10/27 at 14:59 UTC (Orbit 145). Also note that hams on
the ground heard or worked the Shuttle Columbia crew on several other orbits
yesterday.
Element set GSFC-031, generated by Ron Parise, WA4SIR, is the official SAREX
set for today. Please note that there is only a six second difference
between element set GSFC-025 (released two days ago) and element set GSFC-
031.

SAREX Keps & Update 10/28
Thursday 10/29/93 @ 01:00 UTC
All scheduled SAREX school and personal contacts are complete. This
mission was, by far, the most successful from a school group success
standpoint. Only 2 school group and 1 personal contacts had to be repeated.
The probability of a successful school contact on the first attempt was
nearly 90% for this mission. During previous missions, our success rate
was between 66-75% The majority of the schools had horizon to horizon
contacts and many schools had 10 or more questions answered. The SAREX
Working Group wishes to thank the school group volunteers for their
outstanding efforts, the AMSAT technical mentors who coached the schools
prior to the contact, and those who helped in the Mission Control Customer
Support room; particularly John Nickel, WD5EEV, and Karen Nickel, WD5EEU.
Because all scheduled SAREX activities are now complete, several additional
general QSO opportunities are now available. While the SAREX Working Group
cannot fully guarantee that the crew will be operating, there is a high
probability that the STS-58 astronauts will be ready to take general calls
over the continental U.S. on these passes. A total of FOUR "scheduled"
passes are now available. The two mentioned in previous bulletins include
orbit 178 at MET 11 days 1 hour 42 minutes (10/29 at 16:35 UTC) and orbit 192
at MET 11 days 22 hours and 29 minutes (10/30 at 13:22 UTC). In addition,
two other "scheduled" passes are now available. These include a pass on
orbit 176 at MET 10 days 22 hours 18 minutes (10/28 at 13:11 UTC) and a
pass on orbit 193 at MET 12 days 0 hours 6 minutes (10/30 at 14:49 UTC).
Please note that many hams on the ground heard or worked the Shuttle Columbia
crew on several orbits today.
Element set GSFC-031, generated by Ron Parise, WA4SIR, will continue to be
the official SAREX element set. When last checked by Gil Carman, WA5NOM,
there was less than a one second difference between the orbiter state vector
and element set GSFC-031.
