- STS-64 SAREX Update
-
- The next Shuttle Amateur Radio Experiment (SAREX) mission is now less than two

- for launch on September 9, will carry SAREX voice and packet radio on a 9 day
- mission. More details on the upcoming SAREX flight are described in the
- detailed information sheet below.

- School Group Participation: 10 school groups will participate
- in SAREX with pre-scheduled direct
- and telebridge contacts. These include
- nine in the U.S., and one in New Zealand.
- Prelaunch Keplerian Elements:
-
- These are the Keplerian elements for STS-64 mission, rotated to the
- current planned launch time of Sep 9 at 20:30 UTC. The JSC-005 epoch
- is at the start of orbit 5, after the trim burns on orbits 3 and 4. The
- negative drag fit was required to match the design trajectory because there
- is a 6.5 fps trim burn on orbit 28. The phasing and circ burns on orbit 99
- lower the altitude by about 8 n.mi, so the second element set JSC-006 is
- required after that. These Keps are provided by Gil Carman, WA5NOM
- at the Johnson Space Center ARC.

- Mode-S : MA 120 to MA 122 |<- S beacon only

- Mode-B : MA 180 to MA 256 | Move to attitude 230/0, Sep 12

- N QST *** AO-13 TRANSPONDER SCHEDULE *** 1994 Sep 12 - Dec 19
- Mode-B : MA 30 to MA 150 |<- OFF Oct 22 - Nov 07 for eclipses
- Mode-B : MA 150 to MA 190 | max duration 2h 12m
- Mode-BS : MA 190 to MA 218 |
- Mode-S : MA 218 to MA 220 |<- S beacon only

- Omnis : MA 250 to MA 140 | Move to attitude 180/0, Dec 19
- The battery charge state is of paramount importance during the eclipse
- seasons. As always the command team may have to have to make temporary
- changes to the published schedule. In that case we will try to minimize
- the inconvenience, setting Mode-B OFF from MA 230-256 in the first
- instance.

- RS-10: In last week's OSCAR Status Reports NO1R reported that he has made
- some very spectacular contacts with his very modest Mode-A station
- arrangement. His station set-up includes a Kenwood TR-751A at 25 watts
- into a AEA Isopole up about 35 ft. His receiver is the Realistic HTX-100
- into an inverted-vee up about 30 ft with an Advanced Receiver Research 10M
- preamp. This week NO1R reports that he has just received a QSL from Andy
- Mironov at RS3A confirming my RS-10 Robot QSO in April. Andy also writes:
- "I will be glad to have any info abt your work via RS: your DX? PSE send
- by post or packet. 73 Andy" The packet address is for Andy is:
- RK3KPK@RK3KP.RUS.EU [NO1R]
-
- AO-13: N7RYW would like to pass on a note about the Mode-S transponder. He
- has noticed that there is one station who continually sweeps the uplink,
- looking for his downlink signal. This is fine normally, N7RYW says, but as
- this station starts to increase his power far in excess of what is needed
- when he is unable to find himself. The net effect of this is that other
- stations can't hear themselves either because the AGC on the uplink receiver
- has reduced its sensitivity to compensate for this strong signal. This has the
- effect of reducing the AGC affects EVERYONES, making it impossible to even hear
- their own signals! N7RYW has tried to respond to this station CW CQs when it
- finally does settle down (over 20 minutes one day!), but it does not respond
- to N7RYW's SSB call. N7RYW says he doesn't have a key, and doesn't want to
- install one just for just one single lid! All of the Mode-S users N7RYW has
- talked with are well aware of the power limits for uplinking with this one
- exception. N7RYW will not single out this person with their callsign, so he
- hopes a call to him in this way, with as much information as possible, without
- the call, will get his attention. This problem is ongoing, and serious. A
- station recently was attempting their first QSO on Mode-S a few days ago, and
- could not get it done due to this over-powered signal wiping out the trans-
- ponder. This is definitely NOT radar, which does not start sending
- CQ CQ CQ DE *****! While it won't help the excess power problem, this item may
- help people "find themselves." N7RYW has found that the Mode-S transponder's
- actual downlink appears to be 2400.735 MHz to 2400.765 MHZ, up 30 kHz from
- those published. N7RYW does not own a signal source with that high of frequency
- to verify this, but the UO-11 beacon passed zero Doppler within 1 kHz of the
- published frequency, so N7RYW would like to hear if anyone else has found those
- frequencies to be more accurate so he can verify and notify!
- [N7RYW@teleport.com]
-
- KO-23: N7RYW reports that KO-23 is now back in operation after an OBC crash.
- The groundstation control elected to do a data dump to try to find the
- cause of the crash, so it took a few extra days to get the OBC reset.
- [N7RYW@teleport.com]
-
- KO-25: KO-25 is back in service. Both KITSATs were down at various times
- for output power tests. These tests appear to be over for now. N7RYW has
- noticed that when either one is down due to a crash, a peculiar tone is
- emitted on the transmitter. If you are getting a good signal level, but no
- data, turn up the volume and listen for this tone. It may save you some
- head scratching later! Also, on the two KITSATs, the control station
- usually puts out a notice when one of the sats will not be in regular
- service. They are usually short notices, and originate from HL0ENJ,
- so it might be good to mark all messages from this station for automatic
- downloading in your select files. [N7RYW@teleport.com]
-
- UO-11: The 2401.5 MHz beacon was been heard by N7RYW twice with an unmod-
- ulated carrier. On the first occassion he had the polarization set at LHCP,
- and it was just barely audible. Later he changed to RHCP and the signal was
- very strong. This polarity change was done on a 6' dish with a horn type
- feed with dual probes fed 90 degrees apart, much like a crossed dipole.
- [N7RYW@teleport.com]
-
- AO-16: AO-16 is up and running well. [WH6I]
-
- 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 @ N0QCU. 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.

-
- Send him $25 and you'll get the newest copy of the program and a manual or
- perhaps try Archie (it's shareware)
-
- I use it in my high school physics class and I can attest that it is
- extremely well written and simple to use. There is an FPU and a
- non-FPU version. I've been wanting to ask him if he is thinking of
- complling a Power PC version. Perhaps if you contact him, you
- could find this out and post it on this newsgroup.
