CHANGES TO THE AMSAT KEPS

HR AMSAT NEWS SERVICE BULLETIN 139.01 FROM AMSAT HQ
SILVER SPRING, MD, MAY 18, 1996
TO ALL RADIO AMATEURS BT
BID: $ANS-139.01

Ray Hoad (WA5QGD), AMSAT-NA's Orbital Data Manager, recently
reported that his study to review which satellites should be 
listed in AMSAT's weekly keplerian bulletin is now complete.
Based on the information contained in a number of user comments, 
Ray plans to drop only ARSENE and FY-1/2 from the current AMSAT keps
list.

Ray noted that there seems to be more than enough interest in 
keeping the NOAA and METEOR satellite keps as they are currently.
There are also some individuals who listen for POSAT and UO-14 
even though these satellites are not in amateur service at this time. 
Therefore POSAT and UO-14 will stay on the list for now. OKEAN-1/7 and 
SICH-1 will be ADDED to the kep list. 

Ray offered thanks to all for their comments and also offered his 
apologies if the process seemed drawn out.  However, Ray reports
that a "go slow" approach was needed to allow everyone to have a 
chance to comment.

One other change ... Starting this May 17, the AMSAT keps 
will be sent in two files instead of three.  One file 
named orbs$xxx.amsat will have the AMSAT format keps and 
the second file named orbs$xxx.2l.amsat will contain the
NASA two-line keps.

             1996 AMSAT Annual Meeting and Space Symposium
		         Second Call For Papers

			Holiday Inn, City Center
			      Tucson, AZ
			  November 8-10, 1996
                                
The 1996 AMSAT Annual Meeting and Space Symposium will 
be held on November 8-10, 1996 at the Holiday Inn, 
City Center in Tucson, AZ.  This is the second call for papers 
to authors who wish to submit for this event.  As always, the 
scope of the papers should be on topics of interest to the 
amateur satellite service. 

Topics may include, but are certainly not limited to:

		The Life and Times of AO-13
		Building a Phase-3D Ground Station
		Phase-3D Construction Topics
		DSP-93 Integration
		AMSAT Field Operations
		What's Next for AMSAT After Phase-3D?

The annual meeting committee is also soliciting additional topics 
from the AMSAT community. They have already received some 
interesting proposals, (such as P3D ground station construction)
but they report more input is welcome.

Abstracts from authors should be submitted by June 15, 1996. 
Final versions of all papers should be received by August 15, 1996.
Submissions and inquiries should be made to Dave Burnett, WD8KRV:

By Internet: wd8krv@amsat.org

By Mail:     G. D. Burnett
             4809 E. Pima #223

Information about the Annual Meeting home page will be 
included in future announcements.

JAS-2 BAND PLAN

HR AMSAT NEWS SERVICE BULLETIN 139.03 FROM AMSAT HQ
SILVER SPRING, MD, MAY 18, 1996
TO ALL RADIO AMATEURS BT
BID: $ANS-139.03

The new Japanese JAS-2 satellite, now set for launch as early as August of 
this year, carries both a linear(analog) and a digital transponder.  The 
satellite band plan is as follows: 

1) Analog mode
Uplink:   145.900 - 146.000 MHz
Downlink: 435.800 - 435.900 MHz(inverted)
(same band plan as for the current FO-20)
Output power: 1W

2) Digital mode
1200bps BPSK(NRZ-I), same as FO-20
Uplink:   145.850, 145.870, 145.890, 145.910 MHz
Downlink: 435.910 MHz

Additionally, 9600bps FSK will be available on JAS-2.
9600bps FSK(NRZ-L)
Uplink:   145.870 MHz
Downlink: 435.910 MHz

3) Digitalker
FM voice, max 25 seconds
Downlink: 435.910 MHz
Output power: 1W

4) CW telemetry
Downlink: 435.795 MHz
Speed: 12WPM
(same as for the current FO-20)

JAS-2.]

WEEKLY SATELLITE STATUS

HR AMSAT NEWS SERVICE BULLETIN 139.04 FROM AMSAT HQ
SILVER SPRING, MD, MAY 18, 1996
TO ALL RADIO AMATEURS BT
BID: $ANS-139.04


RS-12--Operating normally
RS-10--Operating normally
AO-27--Operating normally

[ANS thanks Rusty Hack, NM1K, Amsat Area Coordinator 
for Connecticut for this information about RS-10, RS-12 
and AO-27.]

AO-10--Presumably, AO-10 shutdown almost immediately 
after the solar panels were no longer providing charge. 
The shutdown occurred at 14:37 UTC on May 9th, which is 
just a couple of minutes after the tracking program showed 
there was no longer an intersection of the satellite's 
footprint and the terminator.  

[ANS thanks Chris Hill, VK6KCH, for this news on AO-10.]

AO-13--Sees Eclipse of Sun by Moon
A partial eclipse of the Sun by the Moon will deprive 
Oscar-13 of solar power on 1996 May 17 [Fri] from 0030 
to 0225 utc, Orbit 6068, MA 151-195.  Maximum obscuration 
is 73% at 0135 utc, MA 175.

This event will be visible (in the telemetry) from 
South Africa, India, S.E. Asia, and Australia as a 
substantial drop in solar panel temperatures, and 
reduced power production.

The transponders will be OFF during the eclipse period.

Details are also illustrated by a GIF drawing in the 
Internet file:

Otherwise, AO-13 is operating normally

South Pacific stations has been active recently on AO-13 
and some on AO-10. Tada, C21/JA1WPX, is QRV on Nauru and 
Aki, TE9RLI, is on Cocos.  Both have had 55+ signals. Yves, 
FO3PJ, has also been on from Raiatea.  He's a high
school teacher there, not a DXpedition.  He doesn't have 
an amplifier so listen carefully for him.   These stations 
are often heard calling CQ with no-one coming back to them.  
It's a lot of work to put a satellite station on from remote 
locations, and many times the operators must get up in the
middle of the night so we can work them.  KC6DIJ urges, 
"Let's show them that we appreciate it."

[ANS thanks James Miller G3RUH for the AO-13 eclipse 
information and JC Smith, KC6EIJ, for the AO-10 and 
AO-13 operating news.]

WEBERSAT-OSCAR-18--Experienced a software crash at 05:50:11 
UTC on 17-Apr-96.  Initial operating software has been 
reloaded by groundstation controllers, and the satellite is 
currently transmitting telemetry, OBC status, and beacon 
frames on a downlink of 437.102 MHz using right-hand
circular polarization.  The digipeater is temporarily off 
the air. 

[ANS thanks John A. Magliacane, KD2BD, and SpaceNews for 
this bulletin on Webersat.]

LUSAT-OSCAR-19--Continues to provide excellent service to 
users all over the world.  LO-19 is operated by AMSAT-LU 
and operates with a transmitter output power level of between 
0.8 and 1.4 watts with a data rate of 1200 bps.

[ANS thanks Miguel A. Menendez, EA1BCU, John A. Magliacane, 
KD2BD, and SpaceNews for this bulletin on LO-19.]
