MIR UPDATE
HR AMSAT NEWS SERVICE BULLETIN 124.01 FROM AMSAT HQ
SILVER SPRING, MD, MAY 04, 1997
TO ALL RADIO AMATEURS BT
BID: $ANS-124.01
In the STS-84 preflight press conference astronaut Mike Foale KB5UAC talked
about ham radio and his stay aboard the Mir space station. As the schedule
currently stands Mike will be aboard Mir from May to September.
Mike Foale goes on to say ,
"I took my [amateur radio] exam in preparations for STS-56. My commander
then was a pretty serious radio ham Ken Cameron , KB5AWP, and he encouraged
the whole crew to do it. Since then I've enjoyed taking part in those
activities, and I do look forward very much to using the ham radio on the
Mir throughout my stay there to talk to anybody who can speak to me in
either English, American, or Russian.
As for particular items of news - I'm open for anything - I just like
chatting with people. Specifically I request that people just tell me
about
their lives on Earth and what they're doing in their part of the world. I
really enjoy having slightly longer contacts than just the brief
collections of QSOs we do on shuttle. As a long duration crewmember I'm
hoping that [hams] will allow me to talk longer with them, so I can have
some contact with them and their countries and understand the people's
conditions where they live as I fly over them."

MIR:
(New frequencies implemented 1 January 1997:
Uplink 145.2 MHz FM Downlink 145.8 MHz FM)
Note, the above split is used for both packet and voice operation.
ANS has received information that states that all
amateur activity from MIR has been suspended until
further notice.
SAFEX, MIR 70cm Repeater
(Uplink 435.750 MHz FM, Downlink 437.950 MHz FM,
Subaudible tone 141.3 Hz)
ANS has received information that states that all
amateur activity from MIR has been suspended until
further notice.
RS-10:
(Uplink 145.865-145.905 MHz CW/SSB, Downlink 29.36-29.4 MHz CW/SSB)
RS-10 is operational.
RS-12:
(Uplink 21.21-21.25 MHz CW/SSB, Downlink 29.41-29.45 MHz or
145.91-145.95 Mhz CW/SSB)
The downlink on 10m continues to be very strong, with some slow fading
noticeable, but still nice strong signals heard and worked from
Arizona and Puerto Rico into northern NJ.
[ANS thanks Dick Montgomery, N3DV, for this update.]
RS-15
(Uplink 145.858-145.898 MHz CW/SSB, Downlink 29.354-29.394 MHz CW/SSB)
Be aware that RS-15 has battery charging problems. When the satellite is
in the dark it has low output power..
[ANS thanks Geoff Perry for this report.]
(Hint: If SSB doesn't work for you, try CW. CW is very easy
to hear on the downlink!)
RS-16
RS-16's 70 cm, 435.504 Mhz beacon on RS-16 operational.
RS16 had no beacons active on 10 meters ,2 meters .

FO-20
(Uplink 145.9-146.0 MHz CW/LSB, Downlink 435.8-435.9
MHz CW/USB)
Operating normally. Strong downlink signal.
KO-23
(Uplink 145.85, 145.9 MHz FM, Downlink 435.175 MHz FM,
9600 Baud FSK.)
KO-23 operating normally.
.
KO-25:
(Uplink 145.980 MHz FM, Downlink 436.5 MHz FM,
9600 Baud FSK.)
KO-25 operating normally.
[ANS thanks Jim Weisenberger, AA7KC, for his reports on
KO-25 and KO-23.]
AO-27:
(Uplink 145.85 MHz FM, Downlink:
436.792 MHz FM (As of April 1, 1997)
Operating normally. The satellite continuous working
excellently over Europe ,but continues to be interfered with
by non amateur operators.
Current AO-27 schedule information can be found at
www.umbra.com
Tepr 4 = 32 counts 16 Minutes
Tepr 5 = 66 counts 18 Minutes
AO-27 Will turn on Every pass 16 Minutes after entering the sun and will
stay on for 18 minutes. This corrects the early shut off that has been
going on for the passed few weeks.
Northern Stations will see the satellite turn on after AOS for the next
week or so. This is due to the TEPR states being calculated for a while
from now instead of Today. So the schedule will be drifting into a better
state. This gives us a longing time before the schedule gets out of whack.
Thanks goes out to the Alternate Control Station KM4NZ/N1XAU for the use
of their station via the Internet for Controlling the satellite. With
new software that lets me control the satellite at remote sights, He hopes
to be able to keep the TEPR Schedule more up to date.

Menendez, EA1BCU, for this update.]

AO-10:
(Uplink 435.030-435.18 MHz CW/LSB, Downlink 145.975-145.825 MHz
CW/USB)
OZ1MY/Ib reports AO-10 has been FM'ing over the past few days.
Stacey Mills, W4SM, reports that the chances of
damaging AO-10 by uplinking during "FM'ing" are probably
remote. The caution mainly stems from a theoretical consideration.
AO-10's latching relays are set to the omni antenna and the transponder is
on in Mode-B configuration. This all turns out to be perfect since we
can't control the attitude, etc. Each time there's a power spike the
chance exists that the IHU could have a "seizure" and blurt out a pulse to
switch the antennas to higain, switch the transponder off or whatever. Of
course these spikes occur every time we come out of eclipse, but the idea
is to do what we can to minimize the number of power spikes. Occasionally
spikes have "activated" the IHU in the past and caused the beacon to send
out nonsensical data rather than the current constant carrier for short
periods of time. ..and it isn't clear when AO-10 switched to the omni
antenna,

Russ Platt WJ9F, AO-16 Command Team , reports the digipeater on AO-16 has
been on for the last couple of months. In regards to the 2.4 GHz
transmitter, it does continue to work although WJ9F has not been leaving
it on for an entire orbit due to its high current load on the 10 v bus.
The battery charging scheme on the micros is managed during sunlight
by adjusting the RCPSK transmitter power up or down to charge and
not overcharge the batteries since we have no way to turn the solar
cells off. The S-band transmitter does not have the ability to vary
its output so it is a high current draw throughout the orbit. In the
past during Experimenters Days when we have turned on the S-Band
transmitter I had to scale back the output of the RCPSK transmitter
to levels that were difficult to receive and even with these low levels
the onboard software will still turn off the S-band TX if the Battery
voltage drops too low, which it did..
