ARISSat-1 Project Manager, Gould Smith, WA4SXM described the tasks
for the cosmonauts as they turn on ARISSat-1. The work to turn on
ARISSat-1 is scheduled to begin at 1430 UTC on April 11. This means 
that they will begin the procedure of getting the satellite, moving 
the antenna coax, adjusting the antenna switches in the ISS, then 
flipping the three switches on the satellite control panel to ON. 

These switches and the circuitry are designed to keep the satellite 
from transmitting for 15 minutes after all three switches are in the 
ON position. This was done so as not to pose any hazard to the cosmo-
nauts during the EVA to deploy the satellite. Based on this timeline
it is estimated that there will be no transmissions until around 1500 
UTC while the ISS is over the southeastern Pacific. Other than ships, 
southern South America should be the first area to hear the ARISSat-1/
RadioSkaf-V signals.

ARISSat-1 will be in Low Power mode, 40-60 seconds ON and 2 minutes 
OFF. An average 8 minute pass will only have about three transmission 
periods and two minutes can seem very long when waiting for a signal 
to appear. Be patient! The varying ON times occur because the ON timer 
expires depending on the current FM transmission item in progress. The 
ID, telemetry, greeting, SSTV will finish before the transmitter shuts 
off.

The ARISSat-1 team invites you to enjoy the event in celebration of 
the 50th Anniversary of man's first trip into space. Yuri Gagarin 
made the historic trip on 12 April 1961.

SB SAT @ AMSAT $ANS-101.02
First Call for ARISSat-1 Recordings

ARISSatTLM author Douglas Quagliana KA2UPW/5 has issued a first
call for ARISSat-1 audio recordings when the satellite is activated
aboard the ISS between Monday, 11 April 2011 at 14:30 UTC and con-
tinuing until 10:30 UTC on 13 April 2011.

The satellite will be running off of the battery, so the transmis-
sions will be only 40-60 second long. There will be a delay of about 
two minutes between transmissions. That is, about 40-60 seconds ON, 
then about two minutes OFF (silence).

If you are able to make an audio recording of the signals from 
ARISSat-1, Douglas would be very interested in obtaining a copy of 
your recording. He is most interested in recordings of the CW and 
BPSK signals, but if are able to record the voice and SSTV signals 
he is interested in those too.

If you can make an SDR recordings (I and Q) with a Funcube dongle, 
FlexRadio, or SDR-IQ, record at the highest rate that your hardware 
and software supports. If you are making a regular audio recording, 
set the sampling rate to the "highest quality." If you can choose 
sample sizes, for example between 8-bit and 16-bit samples, choose 
the largest size.

Douglas is interested in collecting as large of a sample set of
received ARISSat-1 signals as possible. Please save your recordings 
as .WAV files. Don't use MP3 format and don't convert the record-
ings into MP3 recordings. Leave the recordings as huge .WAV files.

If you successfully record ARISSat-1's signals, please contact Douglas
via e-mail for details on how to get the recording file(s) to him:
dquagliana@aol.com.

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 instit-
utions 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 
radio.
