AO-13 ZRO TESTS RETURN!

ZRO Tests Return To AO-13

The ZRO Memorial Technical Achievement Award Program, or just "ZRO Test"
has a new schedule for September and October '93 via AMSAT-OSCAR-13.  This
activity is a test of operating skill and equipment performance.  Due to
scheduling difficulties only three tests have been set up for this round
so be sure to mark the test dates and times on your calendar.

During a typical ZRO run, a control station will send numeric code groups
using CW at 10 words-per-minute.  At the beginning of the run, uplink power
from the control station is set to match the general beacon downlink stren-
gth.  This is level "zero."  The control operator will send and repeat a
random five-digit number, then lower his uplink power by 3 dB (half power)
and repeat the procedure with a new random number.  This will continue to a
level 30 dB below the beacon (level "A").

A participating listener monitors the downlink signals until he can no long-
er copy the numbers.  Those who can hear the beacon will qualify for the
basic award by copying the code group heard at level "zero".  The challenge
is to improve home-station performance to a point where the lower-level
downlink signals can be copied (levels 6 through 9).

The following schedule of Mode "B" tests were chosen for convenient oper-
ating times and favorable squint angles.  The tests can be heard on 145.840
MHz.  Andy (WA5ZIB) will conduct all the tests.  Mode "JL" tests will no
longer occur due to the failure of AO-13's 70-cm transmitter.  Ed (N5EM)
will be back next year after he completes station calibrations necessary
to insure accurate Mode "B" activity.  His "JL" tests were greatly apprec-
iated.

               Sunday   Sep. 26, 1993 at 0545 UTC
               Saturday Oct.  2, 1993 at 1335 UTC
               Monday   Oct. 18, 1993 at 0430 UTC

Note that the dates and days are shown in "UTC", thus the first and third
tests shown occur in the late evening hours for those in North America.
For example, the October 18th UTC test is at 11:30 PM CDT Sunday night (the
17th).  Any
changes will be announced as soon as possible via the AMSAT HF and AO-13
Operations Nets.

ZRO brochures are available from WA5ZIB, Andy MacAllister, AMSAT VP of User
Operations, 14714 Knightsway Drive, Houston, TX 77083 for an S.A.S.E. with
two units of postage.  The brochure characterizes test procedures, means for
obtaining certificates and gives some historical background about the prog-
ram.  New brochures were not made for the current round of tests, but this
announcement and a graphical presentation of the satellite's view during
the tests will be provided along with the March 1993 version of the
brochure.

All listener reports with date of test and numbers copied should be sent to
WA5ZIB at the address above.  A report will be returned verifying the level
of accurate reception.

AMSAT OPS NET SCHEDULE

Current AMSAT Operations Net Schedule For AO-13

AMSAT Operations Nets are planned for the following times.  Mode-B Nets
are conducted on AO-13 on a downlink frequency of 145.950 MHz.  If, at the
start of the OPS Net, the frequency of 145.950 MHz is being used for a QSO,
OPS Net enthusiasts are asked to move to the alternate frequency of 145.955
MHz.

 Date           UTC    Mode     Phs     NCS     Alt NCS

18-Sep-93       1515   B        96      N7NQM   W5IU
 2-Oct-93       1400   B       160      WA5ZIB  WJ9F
 9-Oct-93       1500   B       101      W9ODI   N7NQM

Any stations with information on current events would be most welcomed.
Also, those interested in discussing technical issues or who have questions
about any particular aspect of OSCAR statellite operations, are encouraged
to join the OPS Nets.  In the unlikely event that either the Net Control
Station (NCS) or the alternate do not call on frequency, any participant is
invited to act as the NCS.

**************************************

Slow Scan Television on AO-13

SSTV sessions will be held on immediately after the OPS Nets a downlink
on a Mode-B downlink frequency 145.960 MHz.

Continuous up-to-date information about AO-13 operations is always available on
the
beacons at 145.812 MHz and 2400.646 MHz in CW, RTTY and 400 bps PSK.  Also,
these
bulletins are also posted to INTERNET, ANS bulletins, Packet, PACSATs, etc.,
and can also
be found in many international newsletters.  [G3RUH/DB2OS/VK5AGR]

AO-16:  Operating normally. SATGATE operations have moved from LO-19 (LUSAT)
to AO-16 (PACSAT).  As KI6QE indicated when the move was made, the number
of files involved is quite small, so it is still possible to keep track of
everything on this satellite even with checking a few times a week.  [WH6I]

UO-22: Operating normally. There were a few good images last week.  [WH6I]

KO-23: Operating normally.  [WH6I]

FO-20: N0NBH reports that FO-20 continues to operate normally after last
week's on-board computer resets.  [N0NBH]

UNAMSAT-1: The Mexican MICROSAT is scheduled for launch late this year on a
refurbished Soviet ICBM designed to carry satellites.  So far Program Man-
ager XE1TU does not have all the final keplerian elements of the intended
orbit.  However, the known parameters are as follows:
              Orbital Inclination  = 73 degrees
              Altitude             = 730 KM
              Orbital Eccentricity = 0.00000000
The satellite will separate from the rocket with no spin.  All transmitters
will be silent at separation and for a period of at least 1 hour.  The VHF
receive antenna and the two halves of the canted dipole for 40.997 MHz will
be collapsed and then they will be deployed 3 minutes after separation.
[XE1TU]

RS-10: HB9RHV is quite active on RS-10 and looks forward to contacts and
schedules for those who would like to make a DX contact.  [HB9RHV]

UO-11: Controllers at the UoSAT Control Centre at the University of Surrey
are requesting the help of the amateur radio community around the world in
collecting information and data from UOSAT-OSCAR-11.  The Forth Diary Oper-
ating system aboard UO-11 has crashed within the past 24 hours.  This has
rendered the spacecraft in a non-nominal operating state.  The collection of
information and data related to the operational condition of the spacecraft
over the next several days will be essential in helping the controllers to
understand the spacecraft's current condition.  Therefore the UoSAT command
team is asking radio amateurs around the world to monitor the spacecraft and
relay any reception reports and or telemetry data collected from the space-
craft to them via G0SYX @ UO-22, G0SYX @ KO-23 or via the INTERNET address:
D.Loughmiller@ee.surrey.ac.uk  UOSAT-OSCAR-11 operates on a 2M frequency of
145.825 MHz and on a 70 cm frequency of 435.027 Mhz.  Controllers are most
interested in which beacon is active at the time of any given observation
and whether the signal contains data or not.  Any telemetry data collected
would be of particular interest to the controllers as well.  Any observ-
ations provided by the amateur community will be most appreciated.  UoSAT
controllers will issue subsequent bulletins about the status of the
UoSAT-OSCAR-11 spacecraft as the situation develops.  [KO5I/G0SYX]

The AMSAT NEWS Service (ANS) is looking for volunteers to contribute weekly
OSCAR status reports.  If you have a favorite OSCAR which you work on a
regular basis and would like to contribute to this bulletin, please send
your observations to WD0HHU at his CompuServe address of 70524,2272, on
INTERNET at wd0hhu@amsat.org, or to his local packet BBS in the Denver, CO
area, WD0HHU @ W0LJF.#NECO.CO.USA.NOAM.  Also, if you find that the current
set of orbital elements are not generating the correct AOS/LOS times at
your QTH, PLEASE INCLUDE THAT INFORMATION AS WELL.  The information you
provide will be of value to all OSCAR enthusiasts.
