HR AMSAT NEWS SERVICE BULLETIN 112.01 FROM AMSAT HQ
SILVER SPRING, MD APRIL 22, 1989
(Edited for Packet by KD9QB, AMSAT Area Coordinator - Indianapolis)
QUIKTRAK 4.0 Will Be Ready For Release For The Dayton Hamvention
AMSAT-NA is pleased to announce that QUIKTRAK version 4.0 (QT 4.0) will
be ready for release on April 28, 1989. Those who will be attending
the Dayton Hamvention will be able to obtain the first available copies
of QT 4.0 at the AMSAT booth during the three days of the Dayton
Hamvention. After Dayton it will be available from AMSAT-NA
Headquarters. This "new" version of Bob McGwier's (N4HY) "premier"
satellite tracking program not only retains many of the fine features
of QT 3.2 but also allows the user more "flexibility" with the addition
of several new features. For example, the number of satellites in
which Keplerian data can be maintained has be increased to 100, up from
the fourteen which QT 3.2 allowed; also, QTH data can now be kept for
over 100 different cities. For those who have auto-tracking capability
incorporated into their OSCAR station, with the up-graded "auto-track-
ing" capability added to QT 4.0, you can now designate up to fourteen
different satellites to be "tracked" by your "auto-tracker" in the
order of their appearance at your QTH. For OSCAR users who "hate to
enter data," a new "full-screen editor" has been added to ease the
"data entry" process. If you enjoy watching the position of the
satellites being displayed on maps, QT 4.0 now supports EGA graphics;
it continues to support CGA graphics with the user choosing between the
two graphics modes by a simple entry in your QTH data file. And for
those who enjoy making "visual" contacts with space objects, N4HY has
not forgotten you! Bob has added a new feature which will inform you
whether it will be possible to visually observe a satellite from your
QTH for a given time-of-day and sunlight condition. And finally, the
feature in which Bob McGwier is particulary pleased with is the "mutual
visibility window" option. Have you ever wanted to set up schedule
with another station on an OSCAR satellite but didn't want to have to
run your tracking program for both QTHs? With this added "mutual
visibility" option you will get a tabular listing of AOS, LOS, MA
count, and duration for all "windows of mutual visibility" between your
QTH and any of the cities you have entered in your QTH database. Also,
for AO-13 users, QT 4.0 will give you the time of "minimum-squint-
angle" between you and a selected city. For other satellites, for
example, RS 10/11, this feature will give you the "time-of-minimum
range" between your QTH and the city you select. So if you are looking
for that "rare DX station," this new option in QT 4.0 will definitely
take the guess work out of the problem. AMSAT-NA has adopted a new
policy on up-grades to QT 4.0 for those individuals who hold valid
copies of older versions of the QUIKTRAK program. If you would like
more information about this new "update" policy, please call Martha at
AMSAT-NA HQ's at (301) 589-6062. [For owners of QUIKTRAK of 3.2 and
earlier versions who will be attending the Dayton Hamvention, you will
be able to "upgrade" instantaneously to QT 4.0 at the AMSAT booth.
Just bring your original disk to the AMSAT-NA booth and it can be done
on the spot.]

Mir Cosmonauts Are Scheduled To Return To Earth On April 27, 1989
According to Ron Broadbent, G3AAJ, European Mir "watchers" have been
monitoring the increasing voice "traffic" between the Cosmonauts aboard
Mir Space Station and ground-stations in the Soviet Union on a frequen-
cy of 121.750 MHz. From all indications, the Cosmonauts aboard Mir are
planning to return to earth on April 27th at approximately 02:30 UTC.
One of the last tasks to be performed by the crew of Mir is to boost
the Space Station into a "parking" orbit which will put Mir at an
altitude of 500 km. Because of the change in the orbit, predictions
based on NASA Element Set #795 [Epoch 89 108.17258843] will be "late"
by about 3 minutes/day starting from April 20th. Thus by April 25th,
Mir will be showing up 15 minutes later that your tracking program
predicts. It has also been reported by "Aviation Week & Space
Technology" [the April 17th issue] that because of a problem in the
Electrical Power Subsystem, there will be no follow-up crew aboard Mir
for several months; Mir will be empty until a repair team can return to
fix the problem. So on Thursday April 27th, Cosmonauts Alexander
Volkov, Serge Krikalev, and Valeriy Polyakov will cease their amateur
radio operations from Mir. U4MIR and U5MIR will go QRT.

WA3NAN To Retransmit "Live" Space Shuttle Communications on HF & AO-13
Frank Bauer, KA3HDO, President of the Goddard Space Flight Center
(GSFC) Amateur Radio Club, WA3NAN, wants to invite all radio amateurs
to listen to the "live" voice communication transmissions between the
astronauts onboard the Space Shuttle Atlantis and Mission Control in
Houston on the following HF frequencies:
1) 3,860 KHz NOTE: WA3NAN can only transmit on four out of
2) 7,185 KHz these five HF frequencies at one time.
3) 14,295 KHz
4) 21,395 KHz
5) 28,650 KHz
For amateurs who live in the Greenbelt, MD area, you will be able to
listen to these transmissions on 147.450 FM simplex; for those equipped
for ATV in the Greenbelt area, you will be able to "see" what is going
on by tuning into the Metro Vision ATV Repeater on 439.25 MHz. For
OSCAR enthusiasts, you will be able to "listen" to what the astronauts
are doing on AO-13 on a downlink frequency of 145.955 MHz whenever Mode
B operation is in effect. The primary mission of STS-30 will be to
deploy the interplanetary space probe Magellan. Magellan is designed
to fly to the planet Venus and "map" it's surface. Frank says that if
everything goes well on Friday, April 28th, launch will occur at 02:24
EDT from Cape Canaveral and deployment of Magellan is scheduled to
occur at 08:42 EDT the same day or after 06:18:00 Mission Elapse Time.
For those who wish to listen, the deployment of Magellan will be the
busiest time and will provide the most interesting listening. After
that event, WA3NAN will be "rebroadcasting" the transmissions only when
the astronauts are awake. Frank says that the "sleep-period" on the
first day of the STS-30 mission will start out at 02:00 A.M. EDT and end
at 10:00 A.M. EDT but that each day the start of the "sleep-period"
will begin an hour earlier everyday after that. The Shuttle Atlantis
will land on Friday, May 5th at 03:20 P.M. EDT. So join WA3NAN on HF
and on AO-13 (when it is visible to GSFC and in Mode B) and listen to
the "excitement" of this Space Shuttle mission and the launching of
America's first interplanetary probe in ten years.

MICROSAT Progress Report #3 From the MICROSAT LAB In Boulder, CO
Jeff Zerr, AMSAT-NA's Engineer in Charge of Mechanical Assembly has the
following items to report from the MICROSAT Laboratory located in
Boulder, CO:
1) AMSAT-NA has taken delivery on the first of four "custom built"
carrying-cases which will be used to transport each of the four
MICROSATs to Kourou, Fr. Guiana. These little "suitcases" had to be
specially designed to hold the MICROSATs on a carefully designed plat-
form that has its own "shock-absorbers." Jeff reports that they are
pleased with the design of the carrying-cases. Each case measures
2.5 ft. by 1.5 ft. by 1.5 ft.
2) All of the solar arrays have been mounted to the "honey-comb" panels
for all of the four MICROSATs. They have also been "electrically"
wired together. Jeff points out that "soldering" the wires to each of
the panels was an extremely delicate operation. If too much heat is
applied, the solar cell "clip" will crack.
3) All the transmitter modules are coming together quite nicely. The
electrical parts are being procured. Custom made "standoffs" were
completed which will hold the circuit boards inside the small 1 inch
thick modules.
4) One of the results of the "battery fit check" was that there was a
"clearance" problem which had to be resolved. Jeff reports that the
battery "cradles" have been reworked and an "extra" 1.5 mm. was found to
solve the problem. The batteries are glued into their respective
"cradles."
5) Flight prototype printed circuit boards have been completed by
Matjaz Vidmar, YT3MV, for both the 70cm transmitter and the 2m trans-
mitter.
6) The onboard digital computer has now moved from the design phase,
"bread-board phase," and is now being fabricated and is ready to be
installed into the first MICROSAT.
Jeff says that the final integration date of each of the MICROSATs is
still May 15, 1989. Volunteers are very much needed; you don't have to
live in Colorado to make a contribution to the MICROSAT construction
effort. If you would like to help AMSAT-NA in this construction
effort, contact Jeff Zerr at (301) 530-7233.

AO-13 Operations Net Schedule For May & June
Many AO-13 users are unaware that there is an AMSAT Operations Net
which is conducted on AO-13 several times each month to help answer
questions about OSCAR satellites and to provide information about the
many exciting things going on in AMSAT. The following is a list of the
times for the Ops Net. Please place this list in a convenient place in
your OSCAR station so that you won't miss out on this interesting net
which is offered as a service to all AMSAT members.
Here is the Ops Net schedule through June:
Date UTC orb-phs NCS
29 Apr 1700 671-231 WA5ZIB (45 minutes)
*** satellite schedule and orientation change anticipated ***
07 May 0300 687-116 N5BF (06 May local time, U.S.)
14 May 0400 702-056 N5BF (13 May local time, U.S.)
21 May 0200 716-188 (20 May local)
28 May 0200 731-105 (27 May local)
04 Jun 0300 746-045 (03 Jun local)
11 Jun 0000 760-152 (10 Jun local)
18 Jun 0100 775-092 W0RPK (17 Jun local)
25 Jun 0300 790-055 (24 Jun local)
Nets can be held on B or JL, but if the AO-13 satellite schedule is
changed such that the Ops Net falls during an "off" period, it will be
rescheduled. Frequencies are 145.950 MHz up and 435.970 MHz up. All
these are for AO-13, but AO-10 is sometimes used, when available.
Again, the scheduling constraints now used are:
1) The satellite(s) used will be in view of at least the 48 states
at the beginning of the Net and for 45 minutes thereafter.
2) The Ops Net will not start before 5 A.M. Pacific time.
3) The Ops Net will not start after midnight Eastern time.
