* UNAMSAT-1 NEWS *
==================
David Liberman, XE1TU, reports that the UNAMSAT-1 spacecraft has not yet 
been launched.  A postponment was announced through official correspondence 
from the Russian Space Agency just a few days before project officials had 
to depart for Russia, and no statement regarding the length of the delay 
was mentioned.  It has now become apparent that the civil and military 
crew involved in the launch of UNAMSAT-1 are on summer vacation, possibly 
delaying the launch until September.   
 
In the mean time, project officials are experimenting with the satellite on
the ground, making small adjustments, and testing the satellite for all 
possible situations.  Through this experimentation, a problem with the
fire code not resetting the CPU was discovered.  All the operating software 
has been loaded on the satellite and is running well.  The BBS is being
used by local amateurs with microsat ground stations.

* AO-13 ATTITUDE CHANGE * 
=========================
The AMSAT-OSCAR-13 satellite has undergone a recent attitude change.  The
following message issued by spacecraft controller G3RUH explains some of
the details:
 
L QST de G3RUH 1994 Jul 05.  Magnetorquing from attitude 243/+5 to 180/0 
commences on Jul 07 [Thu] 0510 utc, orbit 4642/224, and continues for 10+ 
perigees.  Estimated interim attitudes are: Orbit Alon/Alat: 4643 235/+4: 
4645 221/-2: 4647 211/-10: 4649 205/-10: 4651 193/-12: 4653 181/-13, then 
a final adjustment.  For command purposes during this 4-day period mode-S 
beacon is ON MA 140-150, i.e. mode-B OFF for 26 mins.  The new schedule 
will start orbit 4651 MA 150 Jul 11 [Mon] 0851 utc. 73 James.
 
Magnetorquing (attitude changing) is not an exact science, and minor
deviations from the above plan sometimes occurs.
 
Please don't rely on gossip and rumour!  Continuous up to date information
about AO-13 operations is always available on the beacons, 145.812 MHz or
2400.664 MHz in CW, RTTY and 400 bps PSK.  These bulletins are also posted
to Internet, ANS, Packet, PacSats etc., and many international newsletters. 
A 400 bps PSK decoder is available from G3RUH and several DSP products;
display software P3C.EXE etc. from many AMSAT groups.
 
The active command stations are listed below, and constructive feedback
about operations is always welcome.

The above may also be reached via Internet (callsign@amsat.org) and KO-23.
Please remember to state clearly a return address.

* LUSAT-OSCAR-19 NEWS *
=======================
The LUSAT-OSCAR-19 satellite continues to operate without its file server
running.  The following beacon was received from LO-19 by KD2BD in New 
Jersey last week:
 
LUSAT-1>AMARG <UI>:
 
May 21.
 
OBC crashed on May 17 at +/- 2:45 utc, lat 45s, lon 43 w.
Only digipeater is available.
 
LU8DYF, LO-19 command station.
 
Although the file server is not available, the satellite does function as
a digipeater, and other ground stations can be connected to via LUSAT-1.
 
 
* DOVE DECODER AVAILABLE *
==========================
A DOVE-OSCAR-17 satellite telemetry decoding program for the MS-DOS 
operating system has been created by KD2BD and is now available via 
anonymous FTP at pilot.njin.net.  The program has been compressed into 
a file called "duvdec10.zip", and is located in the /pub/SpaceNews/software 
sub-directory at pilot.njin.net.  
 
The program will read and interpret ASCII telemetry transmissions made by 
DOVE-OSCAR-17 and generate reports based on that data.  The software is 
free and is intended for non-commercial use.
