AMSAT-NA Space Symposium & Annual Meeting Set For October 9-11th

Almost 300 satellite enthusiasts have registered to attend the AMSAT-NA
Space Symposium and Annual meeting to be held next weekend in Washington,
D.C. at the headquarters of the INTELSAT Corporation.  AMSAT-NA has assem-
bled an impressive line-up of speakers who will present papers concerning
every aspect of OSCAR satellites.  If you are a beginner or an "old pro,"
if you are interested in PACSATs, telemetry processing, image processing or
S-band operation, this Symposium is for you.  Also, you can get a glimpse
of the future of OSCAR satellites with the many papers about Phase-3D and
discussions of future OSCARs under construction.  All are invited to come
and enjoy this exciting gathering of satellite users.  "Walk-ins" are
invited to come to the Symposium and register at the door.  For more
information on the Symposium and for directions to INTELSAT, please contact
AMSAT-NA Headquarters this week at (301) 589-6062.

AO-16 SOFTWARE RELOAD BEGINS

Ground Controllers Begin Software Reload This Week For AO-16

AO-16 Ground Controllers will begin a major operating system software
reload early this week.  AO-16 will receive a "new-and-improved" version of
the house keeping and file server software.  This will allow AO-16 users to
enjoy the same advantages that UO-22 users now enjoy such as file directory
broadcasts and more efficient operation of the BBS.  The new house keeping
software will give AO-16 Ground Controllers better "controls" over the BBS
and RF power output than ever before.  This in turn will lead to better
management of battery charging and longer spacecraft life.  This new
software will allow ground controllers, for example, to make minor
adjustments to the battery charging algorithm without going through the
tedious process of re-writing the software, compiling, and then uploading
it -- all of which is very time consuming.  According to Jim White (WD0E),
controllers can now "tweak" these parameters on the "fly."  The file server
software improvements will likewise let controllers have better control
over many of the parameters which affect the efficiency of AO-16's BBS.  A
good analogy of this might be your control of the many parameters in your
TNC during HF or VHF packet operations which can drastically affect the
efficiency of your packet station.  So it is with AO-16 -- there are many
new parameters that the controllers can set which will make the BBS more
efficient.  Once this upload has been successfully completed, the same
software will be then installed on LO-19.

Incidentally, for those who are interested, at next week's AMSAT-NA Space
Symposium in Washingington, D.C., October 9-11th, Harold Price (NK6K) and
WD0E will present a paper discussing AO-16's BBS and the battery charging
algorithms included in this new software aboard AO-16.

All AO-16 users are urged to watch the telemetry "text-broadcast" which
will contain the latest status of the software reload.  After the reload is
completed, AO-16 users will need to use the PB.EXE version created on
Febuary 24, 1992 by G0/K8KA.  Earlier versions of the PB.EXE will not work.
Also, AO-16 Ground Controllers ask that hams not transmit until the
software reload has been completed.  By QRMing the ground stations, users
only prolong the re-start of AO-16's BBS.  Stay tuned to the AMSAT Nets and
the ANS bulletins for further updates concerning these software changes.

AMSAT-NA Operations Net Schedule

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 and the Mode
J/L Nets on a downlink of 435.970 MHz.

 Date           UTC    Mode     Phs     NCS     Alt

10-Oct-92       2120   J        145     WB6LLO  WA5ZIB
17-Oct-92       1430   B        163     WA5ZIB  WJ9F
24-Oct-92       1500   B        94      W9ODI   N7NQM

Any stations with information on current events would be most welcome.  In
the unlikely event that either the Net Control Station (NCS) or the
alternate do not call on frequency, any participant is invited to act as
the NCS.

Slow Scan Television on AO-13

SSTV sessions will be held on UTC Saturdays and Sundays.  Mode J on a
downlink of 435.980 MHz, and Mode B immediately after Mode J on 145.960
MHz.  OPS NETS will take priority so look for SSTV activity immediately
after they conclude.
