Jim Sanford, WB4GCS, Eagle Project Manager, has good news this week.  
Jim reported the completion of construction of the first prototype 
of the Eagle 70cm Uplink Receiver.  The receiver has been powered up 
with testing and evaluation starting on May 5.

The receiver was designed by John Stephensen, KD6OZH.  Juan Rivera, 
WA6HTP and the Project Oscar Team implemented the design and produced 
the first prototype. Juan and John have provided extensive documentation
 on the receiver design and construction which is available on AMSAT's 
EaglePedia. See:
http://www.amsat.org/amsat-new/eagle/EaglePedia/index.php/U-Band_Receiver

Support for the CAN-Do! command bus interface was provided by Stephen,
KC0FTQ.  For more information check out EaglePedia:
http://www.amsat.org/amsat-new/eagle/EaglePedia/index.php/Category:CanDo

John described his receiver design, "This is a key component of the 
Mode B linear transponder and provides higher dynamic range than 
Phase 3 satellite receivers. Our 70 cm band is shared and this mini-
mizes interference from the military radiolocation service and provides 
improved performance for users in the amateur radio service".

Juan wrote, "Look for more details on my blogs on EaglePedia over the
weekend.  My special thanks to everyone who made this possible.  It was
a team effort from beginning to end."

Jim concluded, "I wish to express my thanks and gratitude to the entire
team for reaching this significant Eagle milestone!"

AO-51 Schedule Change to Accomodate New Software Testing

AMSAT News Service Bulletin 126.02

BID: $ANS-126.02

AMSAT Vice President of Operations, Drew Glasbrenner, KO4MA, previously 
announced the on-going software upgrade and ensuing testing efforts for 
AO-51.

During the last round of testing and upgrades on AO-51,˙the Command 
Team discovered a problem with the BBS receiver interfering with the 
command system with either UHF transmitter above a certain power level. 
This problem had gone unsolved since launch until the relationship to 
the receiver was found. The good news is the problem goes away when 
that receiver is shut off.
 
The bad news is that particular receiver is the only user receiver the 
operating system allows to access the BBS. A rewrite of the core opera-
ting software is required to work around this issue, and there is 
exactly one person who can do this. For the mean time AO-51 will pri-
marily be an analog mode satellite, until the fix is coded and tested 
thoroughly on the ground.

Testing aboard the satellite has started.  Gould, WA4SXM, AO-51 
Operations Group and Command station has updated the May 2007 AO-51 
(AMSAT Echo) Schedule.  Gould wrote, "We will be testing automatic mode 
switching on AO-51 for 2 days each week on Wed & Thur this month, except
 for Dayton week.  The rest of the time AO-51 will be in 'normal' mode."

The first mode switch already occured on an early US east coast pass 
on 2 May 2007.  The AO-51 schedule for May on the AMSAT web site has 
been updated: http://www.amsat.org/amsat-new/echo/ControlTeam.php

Enjoy these modes and send comments and requests to the AO-51 Operations
 Group at ao51-modes@amsat.org.

FO-29 Telemetry Data Needed

AMSAT News Service Bulletin 126.04
>From AMSAT HQ SILVER SPRING, MD.
May 6, 2007
To All RADIO AMATEURS
BID: $ANS-126.04

The Fuji-Oscar 29 (FO-29) satellite has not been heard for several
days.  Below is a translation of the JARL FO-29 note from their
webpage at: http://www.jarl.or.jp 

"The analog repeater of amateur satellite 'Fuji 3' ceased operation.
We request your help in gathering information during the investigation 
of the cause and restoration of the satellite if possible."

The amateur satellite 'Fuji of JARL 3' (FO-29 and 8J1JCS), used the 
regular analog system continuously, but it was verified that the analog 
repeater has stopped after April 21.

Presently, the control bureau is directing an investigation of the 
cause, collecting information of what happened before the repeater 
stops.  If you collected and/or analyze telemetry, it can help with the 
future restoration and planning of the command station. We ask you to 
help us by providing the following information regarding FO-29 to the 
JARL technical section.

    1. After April 20th: CW telemetry data
    2. After April 20th: Repeater operational details/observations 
       (CW telemetry for the repeater including those times when it was 
       operational or not operational)
    3. If there are phenomenon which you believe relevant, such as 
       signal strength and reception circumstance please send.

On May 3, the JARL command station could command the analog transponder 
off and on.  On May 4 when the analog transponder was turned on the
power balance during eclipse was severely negative.  An attempt at
recondition- ing the batteries may be successful if the power budget is
carefully man- aged.  JARL reported that FO-29 needs to be turned off
for a while.

Although it is possible for the command station to temporarily turn on
the satellite over Japan, users are requested to refrain from attempting
to access the analog transponder.  Any telemetry data received is wel-
comed.
