ARIANE 502 FLIGHT UPDATE 

HR AMSAT NEWS SERVICE BULLETIN 173.01 FROM AMSAT HQ
SILVER SPRING, MD, JUNE 22, 1997
TO ALL RADIO AMATEURS BT
BID: $ANS-173.01

In a Joint ESA/CNES press release it has been announced that the  Ariane 
502 launch campaign has begun.  The joint statement issued by ESA/CNES is 
quoted as follows, exactly as received: 
 
 "The Director General of the European Space Agency (ESA)
 and the Chairman of the Centre National d'Etudes Spatiales
 (CNES, the French space agency), acting on the
 recommendation made following the Flight Readiness Review
 held on 5 and 6 June, have given the go-ahead for the Ariane
 502 flight launch campaign to start today, 16 June, at the
 Guiana Space Centre, Europe's spaceport at Kourou in French
 Guiana.  This decision follows detailed reviews conducted
 over the past few months on the launch vehicle itself and the
 corresponding ground facilities (see ESA/CNES release of 24
 March).
 
 Over the next few weeks, mechanical, fluid and electrical
 integration of the cryogenic main stage, the solid booster
 stage, the vehicle equipment bay and the upper stage of the
 launcher will be proceeding in the Launcher Integration
 Building, while preparatory work will be under way in the
 Final Assembly Building on the upper composite: the Speltra,
 the fairing and the payload made up of two technological
 instrument platforms, Maqsat H and B and two satellites:
 Teamsat (a satellite flying five European technology
 experiments and Amsat P3D (an international radio amateur
 satellite).  Meanwhile, various tests, flight program functional
 simulations in particular, will be continuing in Europe.
 
 These various operations are planned to lead to integration of
 the upper composite and filling of the upper stage and the
 attitude control system with propellant, the target date for the
 Ariane 502 flight now being set as from the end of September
 this year."

MIR FREQ. CHANGE

HR AMSAT NEWS SERVICE BULLETIN 173.02 FROM AMSAT HQ
SILVER SPRING, MD, JUNE 22, 1997
TO ALL RADIO AMATEURS BT
BID: $ANS-173.02

For the third time in less than a year, the Mir FM voice and packet
frequency changed again June 15.  But even as it was made, the
switch to 145.985 MHz simplex was being called tentative and
experimental.  It also was controversial.  As a result, Mir
officially will end the worldwide experiment on 145.985 MHz as
of June 23, but leave the frequency available as an option to the
Mir crew only while Mir is over the US.  Mir packet sysop Miles
Mann, WF1F, said US astronaut Mike Foale, KB5UAC, now aboard Mir,
can use "any channel he wants" when he's over the US, including
145.985, but he has to switch to 145.200/800 when Mir is elsewhere.
Also, the radio will remain on the split pair when the crew is
sleeping.  The new frequency may be used for both voice and packet
operation.

The Mir International Amateur Radio Experiment--MIREX--cited
"numerous complaints from around the world" that the 145.200/800
split-frequency combination did not work very well as the main
reason for trying 145.985.  Last November, Mir changed from 145.550
MHz simplex to the split-frequency pair.  "The radio has been almost
impossible to use since November 1," said Mann, who called 145.985
MHz "an excellent compromise."

In a posting to the AMSAT bulletin board, John O'Hara, KB8TJX, in
Wellsville, Ohio, reports he worked KB5UAC aboard Mir on 145.985 MHz
for several minutes right after the changeover.  "Mike said that it
was working out a lot better for him also.  He said he had trouble
sorting out the voice contacts from the packet and that the duplex
was also confusing to him," said O'Hara, who's AMSAT coordinator
for Eastern Ohio, Western Pennsylvania and the northern panhandle of
West Virginia.

When the "experiment" was announced, Mann had expressed the hope
that if the 145.985 MHz channel worked much better, the Mir crew
might be more inclined to get on the air than previously.  Mann said
the 145.800/200 MHz split-frequency operation suffered from
interference from terrestrial users and drew widespread complaints
from hams in the US, Japan and Australia (145.200 MHz is a repeater
output or input frequency in many countries).  He said the new
frequency complies with the IARU band plan for satellite operation
and will reduce desensing of Mir's 2-meter station by commercial VHF
activities taking place aboard spacecraft in the 143-MHz range.
Mann said MIREX is working on a fix for the desensing problem, and
hopes to have it in operation by this fall.

A return to the 145.55 MHz frequency used previously by Mir was
rejected because it's too close to a popular simplex frequency in
Europe.  Switching to 145.79 MHz also was out because it's in use by
many semi-permanent packet operations.

Equipment aboard Mir includes a Kenwood TM-733, a PacComm Handi-
Packet modem, a dual-band antenna, and a new, huskier power supply
capable of powering the TM-733 to its full 50 W output.  Mann said
the output power typically is 10 W, however.

MIREX requests reports on the 145.985 MHz channel.  Signal and
interference reports go to Dave Larsen, N6CO, Box 1501, Pine Grove,
CA 95665; e-mail doc@volcano.net.

P3D DELAY

HR AMSAT NEWS SERVICE BULLETIN 173.03 FROM AMSAT HQ
SILVER SPRING, MD, JUNE 22, 1997
TO ALL RADIO AMATEURS BT
BID: $ANS-173.03

AMSAT Phase 3D officials remain optimistic despite another delay in
the launch of the Ariane 502 that is scheduled to carry Phase 3D
aloft in mid-September. The European Space Agency, ESA, announced
this week that the Ariane 502 launch will be delayed a couple of
weeks until September 30 at the earliest while the rocket gets
another engine. It's the second delay announced this year for the
Phase 3D vehicle. In March, the launch date was moved from early
July to mid-September. AMSAT-NA President Bill Tynan, W3XO, remains
philosophical about the schedule changes. ''It's more of the same,''
he said. ''We're trying to use all the time they give us
productively.''

Orbital Report On-Line said this week that a faulty component was
detected in the liquid oxygen turbopump of the Vulcain engine due to
fly on Ariane 504. Since the origin of the flaw was identified as a
possible production defect and a similar element is known to be in
the pump of the engine already mounted on the Ariane 502 rocket that
recently arrived in Kourou, French Guyana, the European Space Agency
and the launch consortium (CNES) have decided to remove the engine
and replace it with the one originally scheduled for Ariane 503,
which features a component from an older production batch.

Any delay increases the overall cost of the project, but Tynan
characterized the additional cost factor of the most recent delay as
''noise level.'' He did not have a precise cost estimate. Tynan, who
was at the Phase 3D Integration Lab in Orlando, Florida, said
everything is going along well in the process. ''The RF equipment
integrated fine,'' he noted.

and integration process, see

AO-10 is returning to active life. On June 17th, Dan James,
KE0DH,  in Minnesota and James  O' Neill, WA7OPE,  In
Montana enjoyed an almost solid 1 hour contact, starting at
0420 UTC. The satellite was nearing perigee, moving southeast from out
over the pacific. Both stations had ,at times,  S-9 downlink signals. A
slow, predictable QSB fade was observed, getting worse as AO-10 neared
its lowest point. KE0DH was still able to hear his downlink as AO-10
approached only 4 degrees above his horizon. The following night KE0DH
worked WA3JYM in Pennsylvania and W8LKX In Ohio under the same
conditions.

Both WA7OPE and KE0DH enjoy similar working conditions, gain antennas
on AZ/El mounts, with both stations running about 80 watts output on
the 435 MHz uplink. Very little FM'ing was observed during the hour long
QSO. KE0DH was able to reduce his output to under 25 watts and still
achieve a Q5 downlink! Both Dan and Jim used the updated AO-10
information that Stacy Mills, W4SM, has posted on his Internet web site
to predict how AO-10 would respond before setting up the scheduled
contact.

BID: $ANS-173.07

For the 40th anniversary of the launching of SPUTNIK-1 and the beginning
of the space Conquest, l'Aeroclub of France and Russian Astronautical
Federation are associated to commemorate this event. Last February 20th,
during a conference, they were god fathers for the signature of the
protocol of action between the radioclub,  FR5KJ,  of Jules Reydellet
College in St Denis Reunion Island and the Polytechnic Laboratory of
Nalchik Kabardine Balkar Republique (Russian Federation) The goal of the
Project is to interest as many young people as possible in space matters,
leading to an extraordinary realization and maybe to get a job in this
field. The pupils from the two schools are working on a SPUTNIK 1 miniature
satellite  which will be able to work in space, when it will be hand thrown
by a cosmonaut from the MIR orbital station. 

The Russians will build the satellite body in which will be placed the
transmitter made by the French pupils It will emit a "bip, bip" (sound 
track38 ko) on the 2 meters band starting October the 4th,  1997. During 
one month, every VHF equipped amateur radio station in the world will
be able to receive the signal emitted from the miniature satellite .

Mike Seguin, N1JEZ, finally had some time to work a pass of the MIR /SAFEX
repeater on the evening 6/21/97 @ 2223 UTC over Vermont. Mike reports he 
couldn't key  up the repeater, and he also heard nothing on the downlink. 
He quickly tuned down to the Digitalker freq. 437.925 +/- doppler. There

Signals on RS-12 in North America during May and June (almost 
exclusively daylight passes) are weakened by increased ionospheric 
activity which is keeping 15m active during the daylight hours.  
This makes it especially important for the 'old timers' to warn the 
newcomers on RS-12 to set their uplink frequency and leave it alone to 
prevent sweeping across the 15m band and QRM-ing the terrestrial QSOs 
in progress
