is published every week and is made available for non-commercial use.
* NEW SPUTNIK PLANNED *
=======================
The spare Sputnik satellite that was delivered to Mir along with the Sputnik
model that was deployed from Mir late last year is expected to undergo an
upgrade and be deployed from Mir in the latter part of 1998. The upgrade
will consist of replacing the battery and control boards, and install
circuitry that will allow the satellite to make voice announcements in
French, Russian, and English.

* OSCAR-11 UPDATE *
===================
After ground control operations that took place during the third week of
March, the 145.826 MHz VHF-FM beacon is now transmitting normally. Strong
signals have been received from UoSAT-OSCAR-11. Telemetry shows that the
S-band beacon is ON. Telemetry also indicates that there is a reduction
in the 14 volt line current of about 50 mA and a reduction in the +5 volt
current of about 25 mA. The reason for these changes is not widely known.
A new WOD survey of channels 1, 2, 3, 61 (magnetometers) dated 19-Mar-98
has been started. Anyone using this survey should note the unusual starting
time of 16:00:05 UTC.

* TECHSAT LAUNCH NEWS *
=======================
Speaking on behalf of AMSAT, Shlomo Menuhin 4X1AS announced that at long
last (barring any major difficulties) the Israeli Amateur Radio TECHSAT
II produced at the Technion University in Haifa will be launched in late
April or early May 1998. The satellite will sport a packet radio store
and forward mailbox operating at 9600 baud. The satellite will be
launched from Kazakhstan, and Shlomo will be on hand to represent AMSAT.

* STS-90 ORBITAL DATA *
=======================
The nominal orbital data for STS-90 was posted on the AMSAT web page at:
http://www.amsat.org/amsat/sarex/orbit.html
STS-90 is scheduled for launch on 16-Apr-98 at 18:19 UTC. Based on this
launch date and time, the following Keplerian elements were computed from
a nominal NASA state vector:

* MIREX FILTER PROJECT ARRIVES ON MIR *
=======================================
The Progress 38 cargo rocket that arrived at Mir in mid-March delivered the
new MIREX-DCI antenna filter to the Russian Mir space station. The filter
will be used to prevent interference from a commercial VHF-FM transmitter
on-board Mir from affecting the sensitivity and performance of the 2-meter
packet radio station on-board Mir. The MIREX-DCI filer is a custom designed
antenna cavity filter that will block the offending signal with a combination
of passband and notch filters. The filter system is tentatively planned for
installation in the April/May time frame.
The MIREX team would like to thank all of the supporters of the filter project,
including DCI Digital Communications, Inc, SAFEX, and the SAREX Working Group.
