- * AO-27 OPERATING NOTES *
- =========================
- AO-27 has had its FM transponder in operation on the weekends when the
- spacecraft is in sunlight. The transponder on AO-27 receives on an uplink
- frequency of 145.850 MHz FM, and downlinks on 436.800 MHz FM. As of yet,
- no official operating schedule has been announced, but that hasn't stopped
- amateur experimenters from communicating with others through the satellite.
-
- As an example, John, N8QGC, has been working stations on AO-27 all the way
- from his Detroit area QTH to as far away as Mexico City, Mexico, Baffin
- Island, and the North West Territories. N8QGC usually works AO-27 from a
- mobile station using 10 watts of transmitter power from his Kenwood TM-731A
- and a homebrew 1/4 wave antenna. Even with his low power and small antenna
- system, John has no problem securing a strong signal into the satellite.
- He has even tried accessing the satellite with his ICOM IC-U2AT running
- 2.5 watts and a rubber duck antenna and also had a good uplink signal
- (especially during periods when larger stations were not clobbering the
- satellite uplink with excessively strong signals). Due to the extreme
- sensitivity of this satellite, uplink ERP should be kept below 25 watts.
-
- AO-27 control station Mark, N4TPY, has reported that the satellite has a
- transponder output power of between 2 and 3 watts at the present time, and
- as such, is nearly impossible to receive on a HT with a rubber duck.
- Omni-directional antennas have provided only limited results.
-
- N8QGC uses a 6 element KLM 440-6X yagi rated at 8.9 dB gain to copy AO-27's
- downlink signals. He aims it out his car window and receives the satellite
- well. The doppler shift experienced when communicating through this
- satellite can be quite high. John usually starts listening for AO-27 at
- 436.805 MHz, and tracks it down to 436.790 MHz at LOS.
-
- Santoyo V. Ramon, XE1KK, of Mexico City has reported hearing Spanish
- speaking stations through AO-27 with very strong signals. They are not
- hams, nor are they hearing the satellite downlink. He believes they are
- located in the Caribbean zone, probably Cuba or Puerto Rico, and have been
- heard talking about union elections. He is actively tracking down the
- source of these signals.

- * KEPLERIAN DATA AVAILABLE *
- ============================
- Up-to-date Keplerian data in the NASA 2-line format is available via the

- Current AMSAT Operations Net Schedule For AO-13
-
- AMSAT Operations Nets are planned for the following times. Mode-B Nets
- are conducted on AO-13 on a downlink frequency of 145.950 MHz. If, at
- the start of the OPS Net, the frequency of 145.950 MHz is being used
- for a QSO, OPS Net enthusiasts are asked to move to the alternate
- frequency of 145.955 MHz.

- 21-May-94 2130 B 185 VE2LVC W9ODI
-
- Any stations with information on current events would be most welcomed.
- Also, those interested in discussing technical issues or who have quest-
- ions about any particular aspect of OSCAR statellite operations, are
- encouraged to join the OPS Nets. If neither of the Net Control Stations
- show up, any participant is invited to act as the NCS.
-
- Slow Scanners are invited to join the SSTV sessions on AO-13. The freq-
- uency is 145.955 MHz. The net meets at 45 minutes before Mode S, and on
- Mode B following Mode S on Saturdays and Sundays. Join those sessions or
- convey your wishes for other SSTV skeds to wb6llo@amsat.org, and he will
- coordinate your efforts.

- KO-25: N7RYW has noticed that KO-25 started to become very difficult for
- him to uplink to. This began for him over a week ago. At first, he
- attributed the difficulty to the nearness of AO-21. This week he noticed
- that AO-21 was far out of sight of KO-25, and yet the trouble remained.
- N7RYW does not belive that his keps for AO-21 are off and thus he feels
- there might be something bothering KO-25's receiver. He is wondering if
- the receiver was switched to the secondary frequency. If so, it may be
- hard to find, as it was when KO-25 was first activated. In that instance,
- it was found to be off from its published frequency. N7RWY will be testing
- various uplinks over the next few days to see if he can find where its
- secondary uplink frequency is located. If there any other KO-25 users have
- had problems, please send N7RYW a note at his INTERNET address of
- n7ryw@teleport.com. In a further status report received from WH6I, he also
- notes that KO-25 has been deaf with many stations thinking that AO-21 was
- the cause of the desensing of KO-25's reciever. However, analysis of the
- telemetry and many "re-tries" by some stations with a lot of power seems to
- indicate that desense is not the problem. In fact KO-25 has been deaf even
- when AO-21 is not near it. At the moment it seems that there might be a
- software problem, or perhaps the receiver is on a different (unknown)
- frequency. [N7RYW & WH6I]
-
- AO-16: Working well. [WH6I]
-
- LO-19: Operating normally. [WH6I]
-
- KO-23: Operating Normally. [WH6I]
-
- RS-10/11: Operating normally with very strong signals. [ZS6AOP]
-
- MIR: N0XCZ reports that MIR's Personal Bulletin Board System (PBBS) is
- quite active but it appears to be running with low power. Stations can be
- heard but with weak signals. The MIR PBBS can be heard and worked on a
- frequency of 145.550 MHz, FM, simplex. [N0XCZ]
-
- The AMSAT NEWS Service (ANS) is looking for volunteers to contribute weekly
- OSCAR status reports. If you have a favorite OSCAR which you work on a
- regular basis and would like to contribute to this bulletin, please send
- your observations to WD0HHU at his CompuServe address of 70524,2272, on
- INTERNET at wd0hhu@amsat.org, or to his local packet BBS in the Denver, CO
- area, WD0HHU @ W0LJF.#NECO.CO.USA.NOAM. Also, if you find that the current
- set of orbital elements are not generating the correct AOS/LOS times at
- your QTH, PLEASE INCLUDE THAT INFORMATION AS WELL. The information you
- provide will be of value to all OSCAR enthusiasts.

- Subject: Two-Line Orbital Element Set Format
- To: ham-space@ucsd.edu
-
- As a service to the satellite user community, the following description of the
- NORAD two-line orbital element set format is uploaded to sci.space.news and
- rec.radio.info on a monthly basis. The most current orbital elements
- from the NORAD two-line element sets are carried on the Celestial BBS, (513)
- *253-9767*, and are updated daily (when possible). Documentation and tracking
- software are also available on this system. The Celestial BBS may be accessed
- 24 hours/day at 300, 1200, 2400, 4800, or 9600 bps using 8 data bits, 1 stop
- bit, no parity. In addition, element sets (also updated daily) and some
- documentation and software are also available via anonymous ftp from
- archive.afit.af.mil (129.92.1.66) in the directory pub/space.
