SB NEWS @ AMSAT $SPC0122
* SpaceNews 22-Jan-96 *
BID: $SPC0122
=========
SpaceNews
=========
MONDAY JANUARY 22, 1996
SpaceNews originates at KD2BD in Wall Township, New Jersey, USA. It is
published every week and is made available for unlimited free distribution.
* OSCAR-10 NEWS *
=================
AMSAT-OSCAR-10's orientation is such that its solar panels are not receiving
adequate illumination to maintain a charge on its storage batteries. As a
result, the downlink recently experienced frequency instability, and has now
gone silent. Users should refrain from using AO-10 until sun angles improve
to the point where its storage batteries can one again be charged.
* WEBERSAT-OSCAR-18 NEWS *
==========================
WEBERSAT (WO-18) is currently sending telemetry, photos, weekly whole
orbit data (WOD), and light spectra of the Sun or Earth on Mondays.
The satellite's digipeater is on and can be accessed on an uplink frequency
of 145.900 MHz. Using a terminal program connected to your TNC/PSK modem,
try connecting to yourself or calling CQ "VIA WEBER-1". Repeated packets
will appear on the downlink between telemetry and CCD image data
transmissions.
Photo 10/14 of Ethiopia is the current image. It has great contrast with
very few clouds and land features clearly visible. Use WW1.3 to convert the
photo to a GIF image, then use your favorite graphics program to size it,
and adjust the contrast and brightness slightly.
The satellite continues to have a weak and relatively steady tone of about
1200 Hz in the downlink signal, which can cause reception problems with some
modems. If this problem occurs, a ground-based solution is to adjust the
IF-shift of the receiver to suppress the carrier into the skirts of the IF
filter. Night reception seems to be better than in the daytime.
WOD collection and broadcast will adhere to the following schedule:
13 January/Week4: Temperatures and impact detector, Ch# 14 2F 30 35 3B 40
20 January/Week1: Array currents, Ch# 26 27 28 29 2A 2B
27 January/Week2: User requested channels, Ch# ?? ?? ?? ?? ?? ??
3 February/Week3: BCR, 21 22 29 2F 33 36
10 February/Week4: Temperatures and impact detector, Ch# 14 2F 30 35 3B 40
17 February/Week1: Array currents, Ch# 26 27 28 29 2A 2B
Check your local BBS, an issue of SpaceNews, or AMSAT bulletin for the
current status of your favorite satellite.

* OSCAR-11 NEWS *
=================
The UoSAT-OSCAR-11 continues to function well. UO-11 may be copied
transmitting AFSK data on a narrowband FM carrier frequency of 145.826 MHz.
OSCAR-11 transmits binary and ASCII data at a rate of 1200 bits per second.
Surplus Bell-202 modems can be used to demodulate OSCAR-11 data provided
the demodulated data stream is inverted prior to its application to the
computer's serial port.
The following computer status report was recently received from OSCAR-11
by IK3WVJ:

* W1WXZ SILENT KEY *
====================
Chuck, W9ODI, has reported of the passing of James B. Caton, W1WXZ of Cape
Cod, Massachusettes. Jim died on 18-Jan-96 of a massive heart attack while
he was home. He was 76 years old. Jim was very active on the satellites,
and his callsign was frequently seen in the Pacsat queues. Jim worked over
170 countries on the OSCAR satellites -- quite an achievement. He will be
missed by his many friends.
* STS-72 NEWS *
===============
Space Shuttle mission STS-72 ended on Saturday with a successful pre-dawn
landing at the Kenneday Space Center, Florida.
Kazu Sakamoto, JJ1WTK, provided the following packet radio frames received
