AMSAT-Austria Sponsors Space Education Seminar 16-APR-1994 In Innsbruck
The AMSAT-Austria group (AMSAT-OE) will announce their first Educational
Development Seminar meeting using the amateur radio satllites AO-21 and
DOVE (DO-17). It is most fitting that these satellites will be used to
broadcast the announcement of this meeting because the theme is the
advancement science education through use and observation of OSCARs. Look
for the announcement from DOVE beginning on 15-APR-1994 in its telemetry
broadcasts and look for the synthesized voice message from AO-21 this week.
The meeting will take place on 16-APR-1994 at the Technical Highschool of
Innsbruck, Austria and is being sponsored by the Department of Electronics
and Telecommunication. The presenters planned will be OE1VKW, DG2CV, and
EA2CLS/KB7HTA, and I2KBD. All of these radio amateurs are well know in
educational circles. They have a lot of interesting information for those
in attendence. All are invited to join AMSAT-OE at this seminar. For more
information, contact Wolf Hoeller (OE7FTJ) at his INTERNET address of
uibk.ac.at.
[The AMSAT News Service would like to thank Wolf Hoeller (OE7FTJ) for this

OPERATING TIPS FOR AO-27

N8QGC & N4TPY Offer Some Operating Suggestions For AMRAD-OSCAR-27 (AO-27)
N8GQC has been working staions on AO-27 all the way from his Detroit area
QTH to as far away as Mexico City, Mexico, Baffin Island, and the North
West Teritories. He notes that these are great contacts for a Low Earth
Orbiting (LEO) satellite. In his discussions with the AO-27's ground con-
trol station station operator N4TPY, N8GQC has put together a list of "good
operating practices" that N4TPY would like all those who use AO-27 to
follow:
1. Please use as little power as possible. It is recommended that you
use your H/T when possible. If not, then use no more then 25 Watts
ERP.
2. Please try to be kind to other satellite operators. The object should
be to make as many contacts as you can, and to step on as few as
possible.
3. The satellite has no set schedule of availability at this time. The
control stations will make it available only on weekends during daylight
passes. Sometimes during the week AO-27 may also be on, but it will be
"hit or miss."
N8QGC has worked AO-27 with a very simple set up. He transmits on the
uplink frequency of 145.850 MHz using a homebrew 1/4 wave vertical antenna.
His total uplink power is 10 watts. N8GQC find that this gives him a very
strong signal into the satellite. But he especially wants hams to know
that he has also worked AO-27 using a H/T with a "rubber-duck" antenna and
2.5 watts output! However, receiving this satellite can be somewhat
difficult. N8QGC uses a KLM 440-6X antenna to receive. This is the the same 6
element UHF YAGI that he uses for transmitting on AO-21 when he isn't
communicating through AO-27. AO-27's downlink can be heard on on 436.800
MHz. N8QGC is in the process of experimenting with several different
receiving antennas. For mobile operations using AO-27 he has tried using
his full-wave 70CM antenna on the car but has noted that doesn't work
very well. On the receive side, he reports, it still takes a 6 element
Yagi antenna.
By keeping the above suggestions in mind, all users of AO-27 will be able
to enjoy it to its fullest capabilities.

SATELLITE W.A.E.Z.S. AWARD
HR AMSAT NEWS SERVICE BULLETIN 092.03 FROM AMSAT HQ
SILVER SPRING, MD APRIL 2, 1994
TO ALL RADIO AMATEURS BT
BID: $ANS-092.03
Worked All European Zones by Satellite (W.A.E.Z.S.) Award Available
AO-10 and AO-13 user Mario Di Iorio (IW6BNC) is active from his QTH in
Macerata located in the center of Italy, grid square JN63RH. Mario is also
the manager of W.A.E.Z.S (Worked All European Zones by Satellite) Award.
Mario reports that very few radio amateurs know of the existence of this
award. The European zones are: 14, 15, 16, 20, and 40. The award is divided
into a bronze, silver, and gold award. The follwing is the criteria for
each catagory:
1) The basic award or the "Bronze" award can be obtained with a single QSO
with any radio amateur station in Macerata, Italy and 3 European
zones.
2) The "Silver" award can be obtained with making contacts with 4 European
zones and 1 operator from Macerata, Italy.
3) The "Gold" award can be obtained with 5 European zone contacts plus one
contact from any station in Macerata, Italy.
The follwoing are the only valid amateur radio operators from Macerata.
And they are are: 1) IK6LMB, 2) IW6BNC, 3) IK6MQM. Send your requests for
this award to:
W.A.E.Z.S AWARD MANAGER
c/o A.R.I. MACERATA
P.O. BOX 66
62100 MACERATA - MC ITALY
and please include 10 IRCs.
The orginal QSL cards are not needed as proof of confirmation of the contacts
but only a list of QSOs containing all the details of the contacts between
the stations involved. This award is valid for a single satellite but it
changes with respect to the different modes of operation, e.g., SSB, CW or
a mix of the the two modes. IW6BNC hopes to see many stations striving to
obtain the W.A.E.Z.S award. If you have further questions about this award
and its rules, direct your inquiries to:
Mario Di Iorio (IW6BNC)
P.O. Box 66
62100 Macerata - MC
Italy
Or you can send IW6BNC a packet message to his local packet radio BBS of
IW6BNC @ IW6BET.MC.ITA.EU.

WA5ZIB Offers The Some Observations On The Recent AO-13 ZRO Tests
The current round of ZRO Tests via AO-13 are complete. No tests were
missed and all went well. Some interference was experienced on the Feb-
ruary 19th test, but it was not critical. The tests of February 19th and
26th were completed just prior to AO-13's switch to Mode "S" with no time
available for discussion with participants after the tests. These ZRO
tests were scheduled very close to the mode-switch time due to a minor error
in predictions made months in advance. The February 26th test was begun a
few minutes early to ensure that all levels would be sent prior to mode
switch. Many thanks to those on the AO-13 AMSAT Operations Net that
identified the potential schedule conflict before it became a problem.
No new Z9 reports have yet been received, but there's plenty of time to
send in submissions. There is no charge for copy verification although an
S.A.S.E. is appreciated. Send your copy to: Andy MacAllister (WA5ZIB),
AMSAT V.P. User Services, 14714 Knights Way Drive, Houston, TX 77083-5640.
More tests will be scheduled during the next season of Nadir pointing for
AO-13. The dates will be posted to the AMSAT News Service (ANS).

AO-21: N8QGC has been working AO-21 from Detroit QTH and notes that AO-21
is operating normally. It is on the following schedule: 5 minutes of FM
repeater operation followed by 4 minutes of WEFAX transmissions. Fin-
ally, the cycle is conclued with 1 minute of packet before switching
back to FM repeter mode. [N8QGC]
AO-27: AO-27 now acting as a 'J' mode FM transponder and is proving very
popular in Europe, with increased activity daily. It has a strong ex-
cellent quality downlink that can easily be heard on a hand-held receiver
on 436.800 MHz +/- some 10 KHz of shift Doppler shift correction. It's
sensitivity is far greater than 'B' Mode on AO-21. If there are no QRO
stations on 145.850 MHz (+/- some 3 KHz of Doppler shift), uplinking us-
ing a hand-held which can produce 2 watts ERP is capable of putting an
excellent full quieting signal into the transponder. As evidence G3IOR
has worked several other European stations using 2.5 watt hand-held
dual-band transceivers and for optimum footprint coverage to VE8DX who
was running just 3 watts into a ground plane omni-directional from Baffin
Island. All were fully quieting signals! [G3IOR]
STS-59: A brief reminder that STS-59 is scheduled to be launched on 07-APR-94
at 12:07 UTC and will carry the Shuttle Amateur Radio Experiment
(SAREX) payload. For complete details, please refer back to the
$ANS-071.02 bulletin.
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.
