PHASE-3D STATUS REPORT!

The Phase 3-D Project Shifts Into High Gear
Following a series of meetings both in the United States and Germany
involving key members of the International Phase 3-D Project Development
Team, work on construction of the new amateur satellite is moving forward
at an accelerated pace.
On December 11th and 12th, Hanspeter Kulen, DK1YQ, along with Dr. Karl
Meinzer, DJ4ZC, AMSAT-DL President and Phase 3-D Team Leader, hosted a key
meeting of the project's international participants near Munich, Germany.
AMSAT-NA's Vice President for Engineering, Dick Jansson, WD4FAB, and Dr.
Tom Clark, W3IWI, AMSAT-NA's President Emeritus and a key member of the
Phase 3-D GPS experiment group, were also in attendance. Both Dick and Tom
report that all phases of the project are "on track" for the expected
launch of Phase 3-D in 1996.
"Each country's team is performing their assigned tasks very well," said
Jansson on Dec. 13th, soon after his return from Germany. Clark observed
that, "we are really pulling together as an international group." He went
on to note that, "thanks to the work of our European, South African and
Japanese friends, it now looks like we'll have some superb cameras, some
really 'hot' receivers and some very powerful transmitters on Phase 3-D
when it's launched in 1996." Specifically, Dick mentioned that Mike
Dorsett's (G6GEJ) effort's on the spacecraft's 2 Meter transmitter are
right on schedule and that Mike's proposed construction approach has
already met all the key design parameters.
During the Munich meeting, Jansson was presented with a token of appreci-
ation by Dr. Karl Meinzer for his outstanding contributions to the project.
Karl cited Dick's superb design work on the Phase 3-D structure and thermal
control system as well as his tireless efforts in support of the overall
international project.
Just prior to his meetings in Germany, Jansson met with both students and
faculty members from AMSAT-NA's team at Weber State University in Ogden,
Utah. Weber students are now in the process of building the flight model
structure for Phase 3-D. Dick reports that this vitally important portion
of AMSAT-NA's role in the overall effort is "also on schedule for delivery
of flight hardware next June."
Other major contributions by AMSAT-NA to the project in the coming year
will include the purchase of the spacecraft's heat pipes, solar panels and
flight batteries, as well as final construction of the spacecraft's GPS
positioning experiment, antennas and propellant flow hardware. In addition,
yet another group of some 15 dedicated volunteers have now been assembled
in the Orlando, Florida area. These people are already in the process of
both securing and preparing the spacecraft's final integration facility.
This team will also assist other project team members with integration
activities beginning in mid-1994.
Jansson concluded by saying, "there is still a lot of work left on all
of our plates between now and 1996." He also had high praise for the many
volunteers now working on the project. "The ongoing work of our volunteers
is of high quality, and is much appreciated. Without their selfless
efforts, the Phase 3-D project simply would not happen." Jansson said.

K6OYY Passes Along Some Information About KITSAT-OSCAR-25 (KO-25)
K6OYY has received an informative message from Mr. Hyungshin Kim of
SaTReC/KAIST in Korea. Mr. Kim reports that the KO-25 images are not
currently on KO-23, but that they will be available on KO-25 when its BBS
is opened up sometime next year.
Currently images on KO-23 have the designation KAIWxxxx or KAINxxxx
depending upon which imaging system was used; images from KO-25 will have
KBIWxxxx or KBINxxxx as file designations.
In response to K6OYY's inquiry, Mr. Kim also indicated that it is possible
for amateur experimenters to process the COLOR images from KO-25! He fur-
ther stated that the designer of the KO-25 color CCD camera is preparing an
article on how to do this.
KO-25 continues transmit strong signals with good modulation quality as
received here by K6OYY at Santa Barbara, CA QTH. The Kitsat Team is very
busy at the moment conducting experiments with the various systems on
KO-25. Mr. Kim reports that one of his collegues has been asked to
prepare an article for the AMSAT publications.
[The AMSAT News Service (ANS) would like to thank Jim Shepherd (K6OYY) for
the information which went into this bulletin item. For those on who live

WA6ZVP Explains Working One Of the Russian Cosmouauts Aboard MIR
WA6ZVP noting one morning this past week that during a MIR pass on the west
coast would provide him a good pass for a visual sighting. Getting up just
as the spacecraft came above the horizon, he had noted again that the AOS
time was about 3 minutes or so before it would pass out of the earth's
shadow. With his receiver set to 145.550 MHz, he started to hear the
normal packet traffic.
Just as WA6ZVP was about to go outside his house, he started hearing voice
traffic but at first thought it was just some of the Los Angeles "locals"
going QRMing the frequency and complaining about the packet traffic.
Much to his surprise, however, when WA6ZVP turned the volume up to hear the
voice of a cosmonaut speaking broken but very understandable English. The
cosmonaut was in a QSO with another station which could not be hear locally
or from a mountain top remote.
During the 5 or 6 minutes that I heard him, he did not identify so I don't
know what call he is using. Presumably it was R0MIR. The best that WA6ZVP
can recall, the cosmonauts have not been on voice for over 4-6 months.
For all those wishing to work R0MIR, please listen first before
transmitting packet. As in the case of WA6ZVP, you might be suprised!

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. If, at the
start of the OPS Net, the frequency of 145.950 MHz is being used for a QSO,
OPS Net enthusiasts are asked to move to the alternate frequency of 145.955
MHz.

Any stations with information on current events would be most welcomed.
Also, those interested in discussing technical issues or who have questions
about any particular aspect of OSCAR statellite operations, are encouraged
to join the OPS Nets. In the unlikely event that either the Net Control
Station (NCS) or the alternate NCS do not call on frequency, any
participant is invited to act as the NCS.

For CW, pick the shortest possible call that ends with a dash (since dits
are more likely to get lost in the noise). Also it should not end with
a K or anything that sounds like a prosign. If I were still in 3-land,
I'd go for something like NE3T or NE3A.

NOTES:
These VHF DX prediction charts are defined for the 30 MHz to 220 MHz
bands. They are based primarily on phenomena which can affect VHF DX
propagation globally. They should be used only as a guide to potential
DX conditions on VHF bands. Latitudinal boundaries are the same as those for
the HF predictions charts.
