SB ALL @ AMSAT $ANS-100.01
Phase 3C Launch Preps On Sked
HR AMSAT NEWS SERVICE BULLETIN 100.01 FROM AMSAT HEADQUARTERS
WASHINGTON, DC April 09, 1988
TO ALL RADIO AMATEURS BT
Late reports direct form Kourou indicate all is well with preparations for the
launch of Phase 3C on or about June 1. The spacecraft has been tested at the
launch site and, after a few minor bugs were remedied, is now being readied
for the critical fueling operation.
According to Jan King, W3GEY, AMSAT NA's team leader in Kourou, the spacecraft
is in good condition following complete check out of all its systems except
the propulsion system. The propulsion system will be checked out in the next
few days. Jan says all the electrical systems were checked out, the
transponders were performing as expected, the attitude control and power
systems are nominal and the solar arrays have been cleaned and prepared for
flight. In addition, the thermal blankets and thermal coatings have been
applied to the spacecraft. The spacecraft will be "closed out" on Tuesday,
April 12. That means that all preparations, save for the fueling operations,
will have been completed. Some members of the first team have already
returned home to Colorado. Teams from AMSAT NA and AMSAT DL have been
preparing the spacecraft for launch at the Kourou launch facility of the
European Space Agency since late March.
Elements of the second team arrived on April 9 in preparation for the actual
fueling operations. The fueling will be accomplished by Dick Daniels and Dick
Sunderland of AMSAT NA and by Wolfgang Mueller of AMSAT DL. The helium
pressurizing gas will be loaded on Wednesday, April 13. On Friday the
nitrogen tetroxide will be loaded. On Monday, April 18, the fueling operation
will conclude with the loading of the Aerozine 50 (AZ50) fuel in the tank.
According to King, preparations of Phase 3C are following the planned time
line perfectly and the atmosphere is relaxed and professional among the team
staffs.
There are two launch windows for the mission if it launches on June 1. The
first is 1110 to 1146 hours UTC while the second is from 1300 to 1440 UTC.
Both windows are for morning launches. There is some softness in the June 1
launch schedule AMSAT has learned, however. If the launch slips to later in
June, the windows may move to an evening launch. King said AMSAT should have a
better understanding of the launch date later in April. He also mentioned the
designation of the launch has been re-asserted as V-22. That yields the
possibility of an out-of-sequence launch since the Intelsat launch scheduled
for May 11 is being called V-23 while the June 1 launch is being called V-22.

Announce Launch Net Plan
HR AMSAT NEWS SERVICE BULLETIN 100.02 FROM AMSAT HEADQUARTERS
WASHINGTON, DC April 09, 1988
TO ALL RADIO AMATEURS BT
AMSAT-NA will originate a multi-function launch information net in support of
the Phase 3C satellite launch now scheduled on (or about) June 1. During the
period just before, during and just after the actual launch, special
information nets, bulletins and broadcasts will distribute the lastest
authoritative information.
The Arianespace launch schedule will control when specific nets and bulletins
will be transmitted. The current plan is based on a launch date of June 1
with a morning launch window opening just after 1100 UTC. Should a change in
launch day or time occur, the AMSAT Launch Information Network Service (ALINS)
plan will be updated accordingly.
North American HF transmit stations will be as follows: WA3NAN at the Goddard
Space Flight Center; W6VIO at the Jet Propulsion Laboratory and of course the
HQ ARRL station W1AW in Newington.
Their operating frequencies will be:
W1AW: Published voice bulletin frequencies for North American coverage
WA3NAN: 3860, 7185, 14295, 21395, 147.45 beaming east on 20m and 15m
W6VIO: 14282, 21280, 3840 or 7165 beaming west on 20m and 15m
W0RPK: 3840 and/or 7165.
A teleconference of launch information sources and transmit stations will be
held from 30-minutes before the primary launch window opens until shutdown of
the Ariane-4 third stage approximately 20-minutes after liftoff.
Other nets are planned for UK, Southern Africa and other locations to be
determined. Repeater operators who wish to obtain ALINS feeds of the launch
should contact the ALINS Manager Ralph Wallio, W0RPK. Repeater operators are
expected to absorb any telecommunication costs associated with their feed.
Complete details of the ALINS with latest schedules and frequencies can be
obtained from Amateur Satellite Report #174. ASR is AMSAT's bi-weekly
newsletter and is a service to current AMSAT members. Contact AMSAT HQ at
301-589-6062 to inquire about membership.

Skitrek Progress Report #11
HR AMSAT NEWS SERVICE BULLETIN 100.03 FROM AMSAT HEADQUARTERS
WASHINGTON, DC April 09, 1988
TO ALL RADIO AMATEURS BT
Our report on the Amateur Radio Supported Transpolar Skitrek Expedition this
week comes from via packet radio from the Soviet Union. It was filed by Rick
Burke, VO1SA, Portable UA0 and was recorded at the University of Surrey,
England, and relayed to AMSAT. Rick spent a month in the Soviet Arctic
supporting the expedition. His message reads in part:
QST FROM VO1SA/UA0. IT IS MY PLEASURE TO OPERATE FROM SREDNIY ISLAND. 79 DEG
33 MIN NORTH 90 DEG 13 MIN EAST. SREDNIY ISLAND IS PART OF (THE) SEVERNAYA
ZEMLYA GROUP AND 627 NAUTICAL MILES FROM THE NORTH POLE.
(THE) AMATEUR RADIO OPERATION FROM THIS LOCATION IS IN SUPPORT OF A JOINT
CANADIAN USSR POLAR SKI TREK VIA THE NORTH POLE. 9 SOVIET AND 4 CANADIAN
SKIERS MAKE UP THE MOVING GROUP. OTHER COMMUNICATION SITES LOCATED AT DIXON
ISLAND/USSR, RESOLUTE BAY/CANADA AND NP28, AN ICE ISLAND NEAR THE NORTH POLE,
SUPPORT THE PROJECT. THE AIM OF THE SKI TREK IS TO JOIN THE TWO COUNTRIES BY A
WALK TO SHOW HOW CLOSE THEY ARE AND HOW MUCH THE TWO NATIONS HAVE IN COMMON.
MY PRESENCE HERE WITH RECIPROCAL OPERATING PRIVILEGES IS PART OF A VERY
HISTORIC EVENT FOR THE SOVIET UNION AND FOR AMATEUR RADIO WITH THE FOLLOWING
FIRSTS:
1ST THIRD PARTY AND RECIPROCAL LICENSING AGREEMENTS BY THE USSR.
1ST FOREIGN AMATEUR TO OPERATE INSIDE THE SOVIET ARCTIC CIRCLE.
1ST EVER PHONE PATCH TO OUTSIDE THE USSR AND DONE BY A NON-SOVIET AMATEUR.
(VO1SA/UA0 WITH VO1CU)
OTHER FIRSTS BY A NON-SOVIET CITIZEN:
PACKET (RADIO) QSO VO1SA-1 TO RA3APR.
CW SATELLITE QSO VO1SA/UA0 WITH CI8CW.
SSB SATELLITE QSO CI8CW AND VO1SA/UA0.
AERONAUTICAL MOBILE OPERATION BY A FOREIGN AMATEUR ONBOARD A SOVIET AIRCRAFT
MANY RADIO, TELEVISION AND PRESS INTERVIEWS (TOOK PLACE) IN THIS COUNTRY
DURING MY STAY. THERE IS MUCH INTEREST IN THIS FOREIGN (CANADIAN) AMATEUR
RADIO OPERATOR WORKING IN THEIR HIGH ARCTIC WITH THE SAME PRIVILEGES AS A
SOVIET CITIZEN. AMATEUR RADIO PLAYED A SIGNIFICANT ROLE IN SOME OF THESE
STORIES AS TELEPHONE PATCHES WERE USED BETWEEN THE REPORTER AND THIS LOCATION.
IT WAS MOST INTERESTING TO VISIT THE SCIENTIFIC RESEARCH ICE DRIFTING STATION
(ICE ISLAND), NORTH POLE 28, ON APRIL 2/88. THE LOCATION OF 4K0DC, 4K0D AND
FUTURE LOCATION OF 4K0DX. VE3CDX (BARRY GARRATT) WILL OPERATE THAT CALLSIGN
FROM NP28 IN APRIL AND MAY OF 1988.
AS I DEPART, THIS APRIL 3RD DATE, 1988, I LEAVE WITH MANY MIXED EMOTIONS. I AM
GLAD TO BE RETURNING TO MY HOME AND WAY OF LIFE IN ST. JOHN'S, NEWFOUNDLAND
BUT ALSO VERY SAD TO BE LEAVING THE MANY KIND GENEROUS PEOPLE WHO BEFRIENDED
THIS ONE CANASKI, WHO SPEAKS LITTLE TO NONE OF THEIR LANGUAGE, AND MADE ME
FEEL WELCOME AT ALL TIMES. I SINCERELY HOPE THIS PROJECT IS ONLY A BEGINNING
OF MANY SUCH EVENTS IN THE FUTURE OF AMATEUR RADIO. GOODBYE DEAR FRIENDS. DOS
VEE DAH' NYA. 73 VO1SA/UA0.
AMSAT is grateful to Advanced Electronic Applications (AEA) for making
available its PK-232 packet units which are being used by the Skitrek
communication support team.
On April 8th the skiers reached 87 degrees north latitude with the Pole only
330 km to the north. Their lightened packs along with moderating temperatures
and good ice conditions have allowed them to make excellent progress of late.
The third air drop is scheduled to take place on Wednesday April 13th. The
"moving group" will arrive at the North Pole on or about April 24th. They will
be joined by a number of dignitaries and press from Canada and the Soviet
Union who will fly in, weather permitting. Barry Garratt, 4K0DX, will also be
travelling to the Pole from Ice Island North Pole 28.
This report is prepared by Rich Ensign, N8IWJ, AMSAT Science Education Advisor
and edited by WA2LQQ for use with AMSAT's Teacher's Guide, "Exploring The High
Arctic From Your Classroom" A continuing series of Progress Reports like this
one may be accessed via packet BBS, AMSAT Nets and the main educator source,
the W0RPK AMSAT Bulletin Board (1-515-961-3325). Progress Report #12 will be
issued on April 16, 1988.

Balloon Test Yields Surprises
HR AMSAT NEWS SERVICE BULLETIN 100.04 FROM AMSAT HEADQUARTERS
WASHINGTON, DC April 09, 1988
TO ALL RADIO AMATEURS BT
The Southern Africa AMSAT Project BACAR (Balloon Carrying Amateur Radio ) was
launched from a small airport near Johannesburg on March 26th at 0500 UTC. Air
Traffic Control had cleared the flight and had given a launch window 0500 to
0515 UTC. The package consisting of a digital voice repeater, a recovery
beacon and parachute was lifted by two weather balloons. The Parrot repeater
is a voice store and forward device which receives 15 seconds of speech,
digitizes it and then re-transmits in voice on the downlink. The uplink was on
145.200 MHz with its downlink on 145.800 MHz. The recovery beacon operated on
145.550 MHz when below 28,000 feet alternating between a few milliwatts and
300 milliwatts.
BACAR achieved an altitude of approximately 75,000 feet. After launch it was
carefully tracked and followed for recovery. Normally the balloons burst after
2 or 3 hours but Murphy apparently is in the balloon business too. By 1700
local time the balloons had failed to burst as expected and the recovery
effort had to be abandoned near the Botswana border. At that time stations
from as far as 500 km away were still operating the Parrot repeater. At 2000
hours local time no more signals were heard and BACAR was given up for lost
somewhere in Botswana near Lobatsi.
In a late report the downed balloon had been located in Botswana but was being
impounded by Botswana police pending clarification of certain issues.
