- G0/K8KA Provides A Current UO-14 Status Report
-
- Jeff Ward (G0/K8KA) reports from the University of Surrey (UoS) that a new
- battery power mangagement algorithm has be installed on UO-14. This new
- algorithm will affect users at times and therefore they should be aware of
- this change. Starting this week, the power amplifier on the UO-14's downlink
- transmitter will be switched on once the batteries reach full charge and have
- remained there for over 5 minutes. However, the power amplifier will be turned
- off if the batteries drop 20% below their full capacity. Because the signal
- strength could vary drastically with this new algorithm, users should not be
- suprised by this, especially, if UO-14 has been in a solar eclipse condition
- for a long period and has also seen heavy usage. The advantage of this new
- battery management algorithm is that it will aid in extending the life of the
- batteries and ultimately the life of UO-14.
-
- Perhaps unknown or unnoticed by users is the fact that UO-14 had been flying
- upside down for a considerable length of time. But G0/K8KA reports this week
- that UO-14 was "flipped" upright. Although users may not have found UO-14's
- inverted attitude a problem, it did produce a concern with the UoS ground
- controllers as they observed high battery temperatures. Now that UO-14 is
- flying upright, users should see an improvement in signal strength with the
- antennas earth-pointing.

- G0/K8KA Announces New PG.EXE Version Available Soon
-
- G0/K8KA reports that a new version of PG.EXE will soon be available
- and will fix some of the shortcomings of previous versions. For those not
- familiar with PACSAT operations, PG is the program which allows users access
- to files stored on the PACSATs for downloading. Also, the user can upload
- files to a PACSAT using PG.EXE. One new feature that will make a lot of users
- happy is the capability to examine partially downloaded file directories.
- Before, unless the user received the entire file directory before the pass was
- over, it was not possible to "view" the directory file. Now partially
- received directory files can be examined.
-
- In an effort to reduce heavy QRM problems caused by the earlier versions of
- PG, now PG waits to see if the the "BBSTAT" indicates if there is an open
- channel and only then does it attempt a connect. This new feature will help
- reduce the QRM problems when many users are trying to connect. Another QRM
- reducing feature which will also improve efficiency is the display of
- "keywords" in files. The idea behind a "keyword" feature is to allow the user
- the opportunity so see if a file stored on a PACSAT is what they want. For
- example, one might look for the keyword "DX" in order to find a file which
- contains the latest DX activity on AO-13. Those not interested in DX could
- bypass that file. PG has a specific command to "view" just the keywords of
- stored files.
-
- For those who just want to read their "mail" or bulletins of general interest
- to all PACSAT users, G0/K8KA has introduced the "LIST MINE," the "List Bull,"
- and the "List All" options. Those who just want to read files addressed to
- them can choose the "List Mine" option. For bulletins, there is the "List
- Bull" option, and for files containing information of general interest to all
- hams, there is the "List All" option. By implementing these new features,
- operations on the the PACSATs will be much more efficient for all users.
-
- Look for the new version of PG.EXE on the AMSAT/DRIG BBS at (214) 394-7438 or
- on CompuServe's HAMNET. If you have questions about this new PG program which
- you would like G0/K8KA to answer, you can send him a mail message on UO-14
- addressed to G0K8KA.

-
- Last Sunday, January 20, 1991 UTC, AO-16's On-Board Computer (OBC)
- crashed over Europe. Immediately, MICROSAT Ground Command Stations secured
- the spacecraft and proceeded to examine memory dumps to find the cause. At
- this time the software bug which caused the "crash" has been found. NK6K,
- WD0E, I2KBD, N5BF, and WB9ANQ will commence reloading of the Bulletin Board
- software shortly. Currently, AO-16 is available for digipeating.

- U2MIR NOW ACTIVE ON PACKET

- SILVER SPRING, MD JANUARY 26, 1991
- TO ALL RADIO AMATEURS BT
-
- MIR PACKET OPERATION SLATED TO BEGIN FEB. 1
-
- Information received from RK3KP through UO-14 indicates that Musa, U2MIR,
- intends to begin regular packet experiments from the MIR space station on or
- about February 1. A complete packet station was delivered to Musa during
- January, and he has been heard and worked testing it out on 144.675 MHz
- simplex over Europe and on 145.550 simplex over the USA.
-
- The first known packet QSO was reported to have been with DB2OS. Among the
- U.S. stations known to have ***CONNECTED are N5BF, W2RS, N8AM, WJ9F, N6XOT,
- and W3/G3ZCZ. In Musa's initial QSOs, he appeared to be using both U2MIR
- and U2MIR-1. The U2MIR-1 call was used for a packet BBS which, when monitored
- over North America on January 21, already had 20 messages on it which had been
- uploaded from various stations on the ground. Several stations were observed
- digipeating through U2MIR-1 as well.
-
- Severe QRM problems were already evident over North America, with numerous
- retries and "Busy" disconnects being observed, even though relatively few
- stations had yet learned of the experimental operation. Things went much more
- smoothly, however, over the Southern Hemisphere. No details are yet available
- on the frequencies and operating patterns to be employed once regular
- operation begins.
-
- As with all satellite-based communications, it is important to listen for Musa
- prior to transmitting. Musa continues to be active on Voice using 145.550 as
- his primary frequency. You must check to see which mode (Voice or Packet)
- Musa is on prior to transmitting. At this point he has only one transmitter
- on-line making it impossible to be on both modes simultaneously. If you
- hear packets on 145.550 check to see that they are coming from U2MIR and not a
- ground based station. There have already been instances when Musa has been on
- voice but stations are sending CONNECT packets. It is up to us to see that we
- make the Amateur Radio operation aboard MIR a Positive experience.

- Eclipses Cause Temporary Change to AO-13 Transponder Schedule
-
- AO-13 has been experiencing fairly long eclipses (upwards of 90 minutes)
- during portions of its orbit. Initially, it was hoped that the charge on the
- batteries would be sufficient to hold up all spacecraft functions during the
- eclipse period. It was discovered that toward the end of one of the eclipse
- periods, the Mode B beacon began warbling and eventually shut off.
-
- The internal battery voltage dropped to a point where a software fuse blew
- and put the spacecraft into low-power mode. This has caused the command
- stations to alter the schedule such that there will be no transponder
- operational during the eclipse period. The eclipses will continue thru
- February 6, 1991 and a slightly modified transponder schedule will take
- effect.
-
- AO-13 TRANSPONDER SCHEDULE
-
- Mode-B : MA 000 to MA 020 |
- Off : MA 020 to MA 060 | <= Eclipse Period
- Mode-B : MA 060 to MA 165 |
- Mode-JL: MA 165 to MA 190 |
- Mode-LS: MA 190 to MA 195 |
- Mode-S : MA 195 to MA 200 | <= Mode B is Off - no swishing!
- Mode-BS: MA 200 to MA 205 | <= QRP on BS please.
- Mode-B : MA 205 to MA 256 |
- Omnis : MA 240 to MA 060 |
-
- This schedule is expected to continue through 06 FEB 91
-
- The command team requests that you make a specific effort to use QRP on Mode
- between MA 200 to 205. This is specifically to help those people who are
- experimenting with Mode S.
-
- The spacecraft attitude for AO-13 is:
-
- BLON = 209.5 and BLAT = 0.7 for 31 December 90
-
- AMSAT-OSCAR-10 appears to be receiving sufficient solar panel illumination to
- support Mode-B transponder operations. The transponder may be used, arefully,
- at all points of the orbit except MA 254 - 006 when eclipses occur. If beacon
- or transponder signals show signs of FMing, users should cease all transponder
- use immediately. An APPROXIMATION of the spacecraft attitude for AO-10 is :
-
- BLON = 0.0 and BLAT = 2.0 for 19 January 91
