KITSAT-A UPDATE
HR AMSAT NEWS SERVICE BULLETIN 123.01 FROM AMSAT HQ
SILVER SPRING, MD MAY 2, 1992 BID:$ANS-123.01
TO ALL RADIO AMATEURS BT
Further information about KITSAT-A.
The launch of the primary payload Topex/Poseidon and the two microsatellites
KITSAT-A and S80-T is presently scheduled for 23 July.92
The KITSAT-A flight model has left the University for electromagnetic
compatibility (EMC) tests and vibration. These important tests will be
completed by the end of this week, after which we will have a week to
prepare for Thermal Vacuum testing.

ZRO TEST SCHEDULE
HR AMSAT NEWS SERVICE BULLETIN 123.02 FROM AMSAT HQ
SILVER SPRING, MD MAY 2, 1992 BID:$ANS-123.02
TO ALL RADIO AMATEURS BT
AO-13 ZRO Test Schedule: May 1992
The ZRO Memorial Technical Achievement Award Program, or just "ZRO Test"
has a new schedule for May, 1992, via AO-13. This activity is a test of
operating skill and equipment performance.
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
strength. This is level "zero." The control operator will send and repeat
a random five-digit number, then lower the uplink power by 3 dB (half
power) and repeat the procedure with a new random number. This will con-
tinue to a level 27 dB below the beacon (level "nine").
A participating listener monitors the downlink signals until they can no
longer 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" and "JL" ZRO tests were chosen for
convenient operating times and favorable squint angles. The "B" tests can
be heard on 145.840 MHz and the "JL" test on 435.945 MHz. Ed (N5EM) will
run the "JL" tests while Andy (WA5ZIB) will continue with "B" runs.
Saturday May 9, 1992 at 1815 UTC "B"
Saturday May 16, 1992 at 0120 UTC "JL"
Saturday May 23, 1992 at 0500 UTC "JL"
Sunday May 24, 1992 at 0400 UTC "B"
Saturday May 30, 1992 at 1745 UTC "B"
Saturday May 30, 1992 at 2000 UTC "JL"
Note that the dates and days are shown in "UTC", thus the test on May 16th
occurs on Friday night for those in North America. The same situation is
true for the tests on May 23rd and May 24th. Any changes will be announced
as soon as possible via the AMSAT HF and AO-13 Operations Nets.
Recently updated ZRO brochures are available from WA5ZIB, Andy MacAllister,
AMSAT V.P. 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 program. A few certificate requests from the previous
round of ZRO tests are still pending but should be shipped by May 9th.
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-NA Operations Net Schedule
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 and Mode J/L Nets
on a downlink of 435.970 MHz.
Date UTC Mode Phs NCS Alt

Guest commentators are planned. Join the Net if you have questions. In
the unlikely event that either the Net Control Station (NCS) or the alter-
nate do not call up frequency, any participant is invited to act as NCS.

AO-13 Spring Schedule Announced
The spring schedule for AO-13 is as follows:
N QST de DB2OS 16Mar92 00:45utc ** AO-13 Transponder Schedule **
schedule Mar 16 - Jun 08
Mode-B : MA 000 to MA 100 ! Mode-JL ON Mon, Wed !
Mode-JL : MA 100 to MA 120 ! Fri and Sat UTC only. ! Alon/Alat
Mode-LS : MA 120 to MA 135 ! S Beacon on "L" days ! 180/0
Mode-JL : MA 135 to MA 150 ! S Transp on "B" days +-----------
Mode-B : MA 150 to MA 256 ! See AMSAT-Journals and Packet
Omnis : MA 240 to MA 030 ! Radio Bulletins for full details.
If any of you noticed Mode B off on May 3 the following is for you.
>From the AO-13 Beacon:
QST de G3RUH. Partial eclipse of the Sun by Moon.
This event will occur on 1992 May 03 [Sun] from 0118 to 0308 utc.
Maximum obscuration will be 40% at 0153, and will be observable on the
telemetry as a drop in solar panel temperature. The lowered illumination will
necessitate the mode B transponder being OFF on orbit 2975 MA 77-100,
approximately 0150 to 0252 utc.
73 de James (Uploaded by DB2OS, 01May02 20:30utc)
AO-10 is currently available for Mode B operation when it is view of your
QTH. PLEASE DO NOT attempt to use AO-10 if you hear the beacon or the
transponder signals FMing.

AO-16 Experimenter's Day Schedule
The AO-16 Command Team has announced the following PACSAT Experimenter's
Day schedule for April and May:
DATE START TIME END TIME MODE
06 May 2035 UTC - 05 May 2145 UTC - 06 May RCO
13 May 0455 UTC - 13 May 0425 UTC - 14 May RCO
20 May 0310 UTC - 20 May 0245 UTC - 21 May RCO
27 May 0625 UTC - 27 May 0600 UTC - 28 May RCO
RCO: Raised Cosine Only, No S-Band.
-------------------------
QRP operations are encouraged on Experimenter's Day. Uplink power should
be limited to 20 watts EIRP. If you are using your AO-10/13 beams, this
means you must crank your power back to about as low as it will probably
go, no more than 2 watts. And don't forget to turn off your amplifier!
While Experimenter's Day operations are scheduled to be conducted weekly,
users are reminded that these operations may be shortened or canceled to
allow uploading of improved spacecraft software. Watch for bulletins on
the AO-16 BBS and/or the telemetry text frame for changes to the schedule.
[ANS thanks Bruce Rahn (WB9ANQ) for this bulletin item.]
