* AMSAT-OSCAR-16 NEWS *
On 11-Apr-2000 at 03:15 UTC, Russ Platt, WJ9F, turned on AMSAT-OSCAR-16's
S-Band (2401.143 MHz) transmitter, and reduced the power of the UHF PSK
downlink transmitter on 437.025 MHz down to 300 milliwatts. Russ operated
the spacecraft in this configuration for 24 hours, and also ran a Whole Orbit
Data (WOD) survey during this period to determine battery drawdown. These
tests are in preparation for returning the satellite to normal operations.

* ARIANE FLIGHT DELAY *
On 11-Apr-2000, it was reported that the next Arianespace Ariane 506 launch
scheduled for 26-May-2000 has been delayed until July since one of the two
satellites scheduled for launch on this mission is not yet ready for flight.
It is unknown at this time whether this will have any effect on the launch
of the Phase 3D satellite currently scheduled for July.
* ILLEGAL CALLSIGN ON UO-22 *
Chris, GW6KZZ reports observing an illegal callsign on UoSAT-OSCAR-22
satellite that keeps appearing. The station is using TRINET as its callsign,
and has appeared in the CL listing a number of times in late March and early
April. Several attempts have been made to contact the station using the
commercial TRINET callsign which is normally used on POSAT, but each
attempt has failed.
Chris reports that the station always seems to be active when UO-22 is to
the west of the United Kingdom.
Any information leading to the identity of this station would be appreciated.
Chris may be reached via UO-22, UO-25, or via e-mail at firstname.lastname@example.org or

* MIR NEWS *
Slow-Scan television transmissions were observed originating from the Mir
space station on Sunday 16-Apr-2000. An image showing the view outside of
one of Mir's windows was transmitted by Mir on 145.985 MHz, although the
orientation of the spaceraft blocked much of the signal from reaching
the earth, making reception more difficult than it has been in the past.
* AMSAT-OSCAR-10 NEWS *
The AMSAT-OSCAR-10 satellite is currently in a "solar orbit", and will
remain in constant sunlight until Wednesday 26-Apr-2000 when eclipses
will begin once again. The sun angle appears to be favorable for the
operation of the transponder at this time, with strong downlink signals
being observed from the spacecraft in recent weeks. AO-10 is not expected
to experience another eclipse-free period until around 20-Feb-2001, and
that period of continuous sunlight is expected to last until early May 2001.
