WD0E Attends JAMSAT Symposium

Jim White (WD0E) reports the annual JAMSAT Symposium was held in Tokyo on
27-MAR-94.  Jim attended representing AMSAT-NA and presented a paper on
MICROSAT construction and operation, the Deep Space Exploration Society
(DSES) radio telescope project at Table Mountain near Boulder, CO, and the
high altitude balloon experiments of the Edge of Space Sciences (EOSS)
group.  The day long symposium included presentations on the construction
and use of quadrifiler helices, a version of the MICROSAT ground station
software implemented in Japanese, and several presentations regarding
Phase-3D.  One of the Phase-3D presentations included a live demonstration
of the prototype camera and electronics for the SCOPE project that will
provide imaging capability aboard the satellite.  Jim reports he was
particularly impressed by the progress on SCOPE and the demonstration of
the capabilities of the camera and electronics.  Presenters included
JA2PKI, JR1SWB, JM3MAJ, JA0FKM and JH7CKF.  An award was presented to Sumio
Nakane (JH3BJN) for achieving satellite DXCC using only a four element
antenna for 2M, a most impressive accomplishment.

The evening prior to the Symposium, JAMSAT held a celebration of their 20th
anniversary.  Jim reports the hospitality was outstanding with great
international camaraderie and a good deal of discussion about satellite
construction and operation.  Jim said he was particularly grateful for the
hospitality and translation services of Sumio Nakane, Miki Nakayama, and
Tak Okamoto.

AMSAT-NA congratulates JAMSAT on its 20th anniversary!

David Liberman (XE1TU) project manager for UNAMSAT at the Autonomous
University of Mexico, is resting at home recovering from hepatitis.
Meanwhile according to Hector Sosa, chief software engineer for UNAMSAT,
the entire student group that has been working on the construction project
of their UNAMSAT-1 MICROSAT for about two years, recently obtained their
ham tickets after they all took the exam for their amateur radio licenses
and have now received their call-signs.  The new licensees are:

Jose Garcia                   XE0IKQ
Juan Zavala                   XE0MMF

Current AMSAT Operations Net Schedule For AO-13

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.

 Date           UTC    Mode     Phs     NCS     Alt NCS
30-Apr-94       2130   B        176     W9ODI   VE2LVC
09-May-94       0000   B        175     W5IU    WA5ZIB

21-May-94       2130   B        185     VE2LVC  W9ODI

Any stations with information on current events would be most welcomed.
Also, those interested in discussing technical issues or who have quest-
ions about any particular aspect of OSCAR statellite operations, are
encouraged to join the OPS Nets.  If neither of the Net Control Stations
show up, any participant is invited to act as the NCS.

Slow Scanners are invited to join the SSTV sessions on AO-13.  The freq-
uency is 145.955 MHz.  The net meets at 45 minutes before Mode S, and on
Mode B following Mode S on Saturdays and Sundays.  Join those sessions or
convey your wishes for other SSTV skeds to wb6llo@amsat.org, and he will
coordinate your efforts.

AMSAT BOOTH AT DAYTON

Look For The AMSAT Booth At The Dayton Hamvention Next Weekend

For those of you who are going to be at Dayton, we look forward to seeing
you.  The AMSAT booth is in the same spot as last year, 445 - 448.  

AMSAT will be holding three sessions during the weekend.  On Friday at 1:00
PM in Room 1, "Getting Stated on the Satellites, Including the Packet Birds."
This will be moderated by Keith Baker KB1SF.  There are two sessions on
Saturday, both in Room 5.  AT 1:00 PM the SAREX session features several
astronauts plus Roy Neal (K6DUE).  And at 3:15 PM, learn all about the
progress on Phase 3D from Dick Jansson WD4FAB, our VP for Engineering. 
Dick is working very closely with all the various individuals and groups
participating in the construction of the satellite and will bring us up to
date on how everything is going.   

This being the 10th anniversary of the first "Ham in Space" and the 25th
anniversary of the founding of AMSAT, this is a very big year for us.  Try
to participate in as many of the AMSAT-related functions as you can.   

We will be holding an informal dinner and get-together Friday evening. Come
by the booth after the Hamvention opens Friday noon and sign up.  The
restaurant can accommodate only those who sign up.

Communications

The Upper Valley Radio Club in Fairborn has graciously invited us to use
their two repeaters while we are in the area.  The 2 meter one is on 145.41
(-) and the 70 cm machine is on 442.375 (+).  Both are located on a water
tower not more than a half mile from the Homewood Suites, where many
AMSATers are staying.  So, handi-talkies on low power ought to work nicely
in that area.  

Of course, DARA will run their usual talk-in on 146.94 (-).  If you can get
through the mob, they do a good job of providing directions.
 
Around the Hara Arena, and at other locations where we need to communicate
:via simplex, AMSAT will use 145.55.  I am sure that it won't be clear, but
no 2 meter frequency is clear during Hamvention.  For those with 70 cm HTs,
I suggest 438.00.  Mine seems to work there.

I understand from Keith Baker KB1SF, who lives in the Dayton area, that 
road construction in and around Dayton is particularly troublesome this
year.  I-75  is reported to be torn up, and down to one lane; BOTH north
and south of Needmore Road (the main way to the arena).  Also, I-675 north
and south are torn up, and down to one lane, in spots.  This is the route
from I-70 down to the Hoomwood Suites in Fairborn, where most of us will be
staying.  So, wherever you're going around Dayton, give yourself plenty of
time. 
 
Travel safely and we'll see you next week!
 
73,

KO-23: Working well.  [WH6I]

KO-25: Working well.  WH6I reported in last week's KO-25 status report that
number of new images can be found on KO-25 but since the wide angle images
are in a new format that so far has not been decoded.  Well since then he
reports that the QUIKDISP.EXE is available on KO-25's BBS for downloading.
This is a program that will display the new wide angle views from KO-25.
WH6I is in the processing downloading several earth image files.  He says
that the file KAIW0008 appears to be on the adriatic coast of the former
Yugoslavia.  [WH6I]

AO-16: Working well.  [WH6I]

DO-17: ZR5JRS finds this to be an excellent satellite to monitor as he
       can receives DOVE with 599 signals when it is at an elevation of
       only 7 degrees.  To date, however, he has not heard the digital
       voice.  [ZRTJRS]

UO-11: This satellite is working well with clear, readable RTTY. The
       digital voice also is received well from ZR5JRS's QTH.  ZR5JRS
      observes that he has to wait until UO-11 is at lest 25 degrees
       above the horizon for him to receive a good copy on UO-11.  He
      notes that this is in contrast to the other OSCAR satellites
      which he copies almost immediately after they rise above his
      horizon.  His only theory about this is that perhaps UO-11
      runs considerably less power than the other OSCARs.  [ZR5JRS]

MIR: Over the last 4 days, the MIR BBS has been switched off. This is
     possibly to prevent clashes with the STS-59 SAREX mission.  However,
     before this, it was relatively easy to access the MIR BBS even using
    2 watts of power at an elevation of 18 degrees with a "Slim Jim"
     antenna.  There have been no reports of voice contacts in South Africa
     that ZS5JRS is aware of over the last 14 months.
     [ZR5JRS @ ZR5GQ.NTL.ZAF.AF]

RS-10/11: Of all the OSCAR satellites, this satellite is ZR5JRS's favorite
          one to work.  His station consists of a 10W Yaesu FT-480R with a
          "Slim Jim" antenna for the uplink, and an old Yaesu FTDX 400 with
          a long wire antenna for the downlink.  From his QTH in Durban,
          grid square KG59MG, he can work stations in Cape Town, which is
          about 1300 KM away and stations Johannesburg which is about 500
          KM away at the same time for about 3 to 4 minutes.  JR5JRS has
          also found that the downlink is about half as strong as the
          beacon signal.  He also uses the beacon signal to gauge cond-
          itions on the 10M band, sometimes hearing the beacon up to 10
          minutes after the satellite has gone below the horizon!
