* MIR NEWS *
============
Several news agencies are reporting that the Mir mission control center
is planning to put the orbiting space station on autopilot in the near
future. Apparently, disruptions in financing for the next mission and
uncertain future prospects are the main reasons for the decision.
Cosmonauts Sergei Zaletin and Alexander Kaleri will return to Earth
about mid-June, first closing down the station and switching the flight
control systems from the on-board computer to an analog system. No
additional flight crews are scheduled to visit the station until much
later this year, at the earliest.
The orbiter has been raised to an operational orbit of 375 to 390 km.
Mission control reports they will not need to perform any orbit
maneuvers until early 2001.
Amateur Radio activity aboard the station has been limited during this
mission. No ham radio activity has been reported from the orbiter during
the last several weeks.

* PHASE 3D TRANSPONDER UPDATE *
===============================
A while ago it was decided to use a two letter designator instead of the
old single letter transponder mode designators on P3-D, simply because
there are so many different combinations of receivers and transmitters
possible.
The first letter stands for the uplink, the second letter for the
downlink.
Letter Frequency Remarks
----------------------------------------------------------------
T 21 MHz Uplink only
H 24 MHz Uplink only
V 145 MHz Uplink and Downlink
U 435 MHz Uplink and Downlink
L 1.2 GHz Two Uplinks only, L1 and L2
S 2.4 GHz Two Uplinks and two Downlinks, S1 and S2
C 5.6 GHz Uplink only
X 10 GHz Downlink only
K 24 GHz Downlink only
These letter assignments are consistent with the usual microwave band
designations, where "K" for example means 18-26.5 GHz.
Unfortunately, the HF bands do not have such fancy letters, so Matjaz
Vidmar S53MV was allowed to decide since he built the 21 and 24 MHz receivers
for P3-D. He commented that the Russian satellites used "T" for their 21
MHz transponder and suggested doing the same. There was no letter for
the 24 MHz RX, however, so the letter "H" was picked for this band.

* PHASE 3D LAUNCH NEWS *
========================
The long-awaited launch of the Phase 3D satellite is currently scheduled
for Ariane mission AR507, which is scheduled for lift-off no earlier than
the middle of September 2000. It was previously believed that the launch
would occur in July.

* FUJI-OSCAR-29 NEWS *
======================
The FO-29 command station of the JARL has announced the following operating
schedule for the satellite:
May 8 (Mon) - June 7 (Wed) : Mode JA
June 8 (Thu) - June 12 (Mon) : Digitalker
June 13 (Tue) - July 2 (Sun) : Mode JA
The most significant change in this schedule is the addition of the
"Digitalker" mode in which the satellite transmits stored audio messages
uplinked by controllers. The Digitalker on FO-29 can be easily copied
on FM receivers tuned to 435.910 MHz (+/- doppler).

* AMSAT-OSCAR-10 NEWS *
=======================
Rudolf, ZR6JRN in South Africa reports that the AO-10 satellite was performing
well during the weekend of 26-28-May-2000. Rudolf reported contacting
DC3ZB, M1CMH/P, EA7AEB, G3WFM, DD7VW, F1BEV, OE3VID, and OH5LK, all with
good signals.
