In this Special Bulletin:

* ARISSat-1/KEDR Test Transmissions Planned From ISS July 30-31

Test transmissions from ARISSat-1/KEDR are scheduled to begin at 
19:15 UTC on July 30 and then continue until 1430 UTC on July 31. 

The satellite will be connected to an external antenna mounted on 
the ISS during testing. During the test ARISSat-1/KEDR will be in
LOW power mode, this means that it will transmit about 40 seconds 
and then shut down for 2 minutes and then transmit for again for 
40 seconds. 

During the ISS test there will not be an antenna connected to the
ARISSat-1/KEDR UHF port. The 435 MHz - 145 MHz Linear Transponder
will not be active during the test period. This transponder will 
be active once ARISSat-1/KEDR is deployed.

To listen for ARISSat-1/KEDR signals, FM receivers should be tuned 
to 145.950 MHz. Even though the satellite will only have an output 
of 250 mW on 2 meters, a standard FM handy talkie equipped with a 
quarter-wave whip antenna should be able to receive the voice ID, 
voice telemetry and greeting messages as the craft passes overhead. 

Those planning to monitor voice broadcasts from ARISSat-1/KEDR 
during the July 30 - 31 test are requested to make note of the 
telemetry battery voltage values and UTC time, and then submit 
their records by e-mail to: julytest@arissat1.org.

SSTV transmissions are included in the cycling FM downlink with
station identification RS01S, voice messages, and spoken telemetry.

SSTV transmissions may also be demodulated and viewed using a free 
downloadable program such as MMSSTV that is available at:  
For Mac users, Multiscan2 is available at: 

If you successfully receive the SSTV transmissions, you can
upload the SSTV picture that you received to:

Given the low duty cycle of the spacecraft, those planning to 
receive and decode the digital telemetry during this test are 
encouraged to record the entire signal band using the FunCube 
dongle or SDR-IQ receivers. 

Software for demodulating the BPSK-1000 telemetry is available 
at http://www.arissattlm.org; 
the software Quick Start Guide is available on the link on the 
http://www.amsat.org front page. 

AMSAT needs your telemetry from ARISSat-1/KEDR both during the 
test and after deployment from the International Space Station. 

Since there are no "Whole Orbit Data" storage mechanisms onboard 
ARISSat-1/KEDR, your submissions are the only way for AMSAT to 
collect the spacecraft telemetry and KURSK experiment results.

If you are running ARISSatTLM and receiving the signal "live" from 
ARISSat-1/KEDR, then please enable the telemetry forwarding option. 
In the PC version of ARISSatTLM you can do this by selecting "Tools" 
then "Options". In the "Options" window, replace "NOCALL" with your 
amateur radio callsign and put a check in the box next to "Forward 
telemetry over the Internet". The destination will already be filled 
in with "telemetry.arissattlm.org".  

If you successfully receive the telemetry from a recording (not live),
please forward your telemetry CSV file and KURSK telemetry files by
e-mail to telemetry (AT) arissattlm.org. These can be found inside 
the ARISSatTLM folder on your Windows desktop in the Kursk and Tele-
metry folders.

And, if you just can't get enough ARISSat-1/KEDR telemetry, remember 
that you can see the latest telemetry LIVE on your computer or cell 
phone at: http://www.arissattlm.org/mobile

This "mobile" page is powered by the submissions from the ARISSatTLM 
users who forward their telemetry over the Internet.

Thanks to David Carr, KD5QGR, ARISSat-1/KEDR has just been added to 
list of satellites at the popular "Live OSCAR Satellite Status Page" 
at: http://oscar.dcarr.org/  Although the transponder will not be 
active this weekend, if you hear the downlink during the test (or if 
you don't hear the downlink) please submit a report.

The Radio Amateur Satellite Corporation (AMSAT) is a non-profit, 
volunteer organization which designs, builds and operates experi-
mental amateur radio satellites and promotes space education. We 
work in partnership with government, industry, educational insti-
tutions and fellow amateur radio societies. We encourage technical 
and scientific innovation, and promote the training and development 
of skilled satellite and ground system designers and operators. Our 
vision is to deploy satellite systems with the goal of providing 
wide area and continuous coverage for amateur radio operators world-
wide. AMSAT is also an active participant in human space missions 
and supports satellites developed in cooperation with the educational 
community and other amateur satellite groups.

Amateur Radio on the International Space Station (ARISS) is a volun-
teer program which inspires students, worldwide, to pursue careers 
in science, technology, engineering and math through amateur radio 
communications opportunities with the International Space Station 
on-orbit crew. Students learn about life on board the ISS and explore 
Earth from space through science and math activities. ARISS provides 
opportunities for the school community (students, teachers, families 
and local residents) to become more aware of the substantial benefits 
of human space flight and the exploration and discovery that occur on 
space flight journeys along with learning about technology and amateur
