Best spot I've found so far is :
FTP to archive.afit.af.mil:/pub/space/....(anonymous login etc)
The files in here are updated daily by Dr Thomas Kelso at about 21h00-23h00.
I am not sure if this is EST or UTC time, maybe someone can tell me!!
There are about 12 files in this directory (/pub/space) with the extn of .tle
The most popular I should think are amateur.tle, weather.tle, sts.tle and
mir.tle.
Hope this is useful.

IARU APPOINTS SATELLITE ADVISOR
HR AMSAT NEWS SERVICE BULLETIN 274.01 FROM AMSAT HQ
SILVER SPRING, MD OCTOBER 1, 1994
TO ALL RADIO AMATEURS BT
BID: $ANS-274.01
IARU Appoints Satellite Adviser
In a news release dated 26-SEP-94, the International Amateur Radio Union
(IARU) announced that it has appointed Hans van de Groenendaal (ZS5AKV) to
the newly created post of IARU Satellite Adviser. According to the IARU
release, the principle task of this position will be to keep the IARU
Administrative Council informed on all technical and operational aspects of
the Amateur Radio Satellite Service in order to enable the Council to adopt
appropriate policies to advance the interest of the Amateur Satellite Service
before the International Telecommunication Union (ITU) and regional telecom-
munications agencies.
The IARU release noted that ZS5AKV, as past President of Southern African
AMSAT and an Executive Committee member of IARU Region 1, brings many years
of satellite related experience to this appointment. The IARU release
further noted that the appointment is a direct result of recommendations
made to the IARU Administrative Council by the IARU Ad Hoc Satellite
Advisory Committee which took up the interim report at the recently com-
pleted IARU Administrative Committee meeting in Singapore. The IARU
release commented that this action is "tangible proof" of IARU's interest
and involvement in the Amateur Satellite Service.
The release continued by citing IARU's many year role in protecting the
Amateur Satellite Service, in particular its work during the 1979 World
Administrative Radio Conference which led to most of the present Amateur
Satellite Service frequency allocations.
The IARU release also stated that the "exponential development of new tech-
nologies and ever increasing complexity of the Regulatory Agencies, the IARU
Administrative Council deemed it necessary to involve itself closer with the
Amateur Satellite Service in order to represent it effectively on a coordin-
ated world-wide basis while cementing its relationship with the AMSAT and
other Amateur Radio Satellite groups."
In the release the IARU said that in his new capacity and by the powers
delegated to him by the IARU, ZS5AKV will have the task of appointing
someone to the post of IARU Satellite Frequency Coordinator.
The IARU said that ZS5AKV is now soliciting nominations for volunteers
willing to serve the function of IARU Satellite Frequency Coordinator.
Such nominations should be sent to him by FAX at +27-31-765-6456 or via
INTERNET at amsat@uctvax.uct.ac.za before 31-OCT-94. Hans said that each
nomination should include a comprehensive summary of the nominee's background
and qualifications. He stated that it is his intention to discuss the various
nominations with major AMSAT groups in order to seek their recommendations.
He underscored the importance of finding the right person to be appointed
to this very important job.

Weekly OSCAR Status Reports: 01-OCT-94
AO-13: Current Transponder Operating Schedule:
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
Mode-S : MA 220 to MA 230 |<- S transponder; B trsp. is OFF
Mode-B : MA 230 to MA 30 | Blon/Blat 230/0
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.
==========================================================================
[G3RUH/DB2OS/VK5AGR]
FO-20: FO-20 has been switched back into the analog mode as of 14:30 UTC
28-SEP-94. The command station announced that "mailbox software ran away"
and there is a malfunction known as UVC (Under Voltage Control) has been
confirmed by command station. FO-20 will be staying in its analog mode
until 10-OCT-94. [JJ1WTK]
MIR: German Astronaut Dr. Ulf Merbold will be QRV aboard the space station
MIR signing DP3MIR during the ESA EUROMIR 94 mission starting 03-OCT-1994.
In order to give actual information regarding the mission to as many radio
amateurs and SWLs as possible, he will use the digital voice memory of MIR's
HAM RADIO rig designed and built by Thomas Kieselbach (DL2MDE). Thomas made
an arrangement with Ulf Merbold, DP3MIR, to load actual spoken reports into
the digital memory frequently, as time permits however, probably every 2-3
days. The reports in English and German will then be retransmitted auto-
matically during the consecutive orbits at 145.550 Mhz (FM) in regular time
intervals. Ulf Merbold will stay aboard MIR for 30 days. [DF5DP]
RS-10: WA6ARA reports that RS-10 is operating well with a good mix of SSB
and CW. Orbit times are great for late evenings to the East and with early
evening passes to the West. [WA6ARA]
RS-12: WA6ARA reports that Mode-K is alive and very well. RS-12 is just
starting to appear in late evenings. Over the next month the passes will
be great for evening passes. [WA6ARA]
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.

Subject: Balloon Launch
Near Outer Space Transportation System (NOSTS-1)
Balloon Launch - Clear Lake Amateur Radio Club
Sunday - October 9, 1994
Near Outer Space Transportation System utilizing a 12 foot diameter
helium balloon as the launch vehicle. NOSTS-1 is an amateur radio
experiment which will carry a various payloads in a package weighing
less than 6 pounds. All interested hams are invited to participate.
The payload consists of:
* 2 meter packet on 145.75 MHz simplex - the node name for digipeating is
NOSTS-1, the mailbox callsign is KJ5MX-6, the beacon IDs as KJ5MX-3.
* 10 meter voice beacon on 28.322 MHz Double Side-Band with an ID interval
of 33 seconds
* Beacon on 29.420 MHz sending "CW" beeps that correspond directly to the
outside temperature. At 70 degrees Fahrenheit the beep rate is
approximately 200/min. To calculate temperature from beep rate the
formula: Temp(degrees F) = [0.56853 X (Beep rate)] - 38
The antenna for this device is a 2 meter dipole cut to enhance the 5th
harmonic at 147.10 MHz for direction finding purposes.
* Beacon on 224.72 MHz for direction finding purposes only.
* Potential secondary payloads may include a 10 GHz gigaplexer beacon and
a 2 meter uplink (147.435 MHz), 70 cm downlink (440.95 MHz) FM repeater.
Final announcements on these payloads will be made on launch day.
The Clear Lake Amateur Radio Club Balloon Launch Team wishes to thank
Andy MacAllister, WA5ZIB and members of the South Texas Balloon Launch
Team for assistance, advice, and use of 220 MHz beacon, 29.420 MHz fireball
transmitter for this launch.
An informal simultaneous HF (7.155 Mhz or up for QRM) and UHF (442.750 SE
Houston | 444.275 MHz NW Houston repeaters) net will be held at 7PM on
Saturday October 8th for final updates. The 40 meter net on the same
frequency will be active immediately before and during the flight.
The lauch site will be west of the Houston area and the direction of
flight will be from west to east. Coverage may extend several states
on some modes. Reception reports including frequency, time, and
YOUR location are encouraged.

What are the sats that I can work with just standard AX.25 1200 baud
packet? I have 2 meter and 440 to work with. I have worked through
CW and voice on some sats, but what are the requirements for running
the pacsats?
Thanks in advance

Subject: Shuttle frequencies
Although I don't think we have the equipment to recieve shuttle
conversations with hams, we'd like to try.
What frequencies do the shuttle missions use for talking to hams ?
Do they use any modes other than FM and packet ? Do they use an offset
between transmit/recieve or is it strictly simplex ?
Also, the last Keplerian data I had for the shuttle was from PRE-launch.
Does anybody have newer data or know where I can find it ?
Thanks,
Reddy
