<H1>Negai - reception reports needed</H1>
<P><FONT face=Tahoma><STRONG>Toyoshige Kamei JA3SGR</STRONG> has requested
reception reports from southern hemisphere stations of the 437.305 MHz beacon on
the Amateur Radio satellite <STRONG>Negai</STRONG> launched May 21.</FONT></P>

<H1>Amateur community needed to assist UNITEC-1</H1>
<P><FONT face=Tahoma>An informal network of ham radio experimenters, scientists
and CW enthusiasts called <STRONG>FlyVenusCom</STRONG> -- a nonprofit,
cross-cultural effort -- has been created to support communication efforts by
Japanese scientists with its CubeSat Venus probe,
<STRONG>UNITEC-1</STRONG>.</FONT></P>

<P><FONT face=Tahoma>UNITEC-1 was developed by 20 universities of the University
Space Engineering Consortium (UNISEC), the Japanese community developing
nano-satellites. Specifically, the Japanese UNITEC-1 team has called for ham
radio assistance worldwide in improving and testing two areas of the CubeSat’s
mission:</FONT></P>
<P><FONT face=Tahoma>* Technologies to receive and decode very weak and low bit
rate signal coming from deep space.</FONT></P>
<P><FONT face=Tahoma>* Technologies to estimate orbit and signal Doppler shift
of the satellite based on the received RF signal, essential for tracking and
receiving signals from a satellite in deep space.</FONT></P>
<P><FONT face=Tahoma>Bill Vartorella, KJ4ORX, is spearheading the informal
FlyVenusCom effort: “The wave of the future is increasingly small, inexpensive,
private and non-profit enterprise satellites. The trade-off is many of these
satellites will not have sufficient power for robust communications. Weak signal
challenges and research publications have been the hallmark of ham radio since
at least the 1920s. What should spur ham interest is that UNITEC-1 will transmit
an Amateur Radio telemetry beacon at 5.840 GHz. ‘Big dish’ participation is
already beginning to gel, but monitoring and reporting the signal is just part
of the equation.”</FONT></P>
<P><FONT face=Tahoma>Vartorella said that the signal from UNITEC-1 is mainly a
CW beacon of about 1 bps speed. “It would also be possible to duplicate the
received signals from several antennae to make the signal-to-noise ratio higher,
so that we can decode the signal from UNITEC-1 while flying further away from
the Earth. This experiment can also be performed in a competition style. We
would greatly appreciate it if radio amateurs would propose interesting
experiments or competitions, making the most of the UNITEC-1 launch and
operation opportunity.”</FONT></P>
<P><FONT face=Tahoma>At the core is the Japanese consortium’s emphasis is that
this is the first university-developed interplanetary satellite -- as well as
the first amateur interplanetary satellite -- that will provide what Vartorella
called “a unique and exciting opportunity for the radio amateurs all over the
world to enjoy reception of signals from deep space. Not many of us have either
a big dish in the back yard or access to one. With FlyVenusCom, we’re trying to
engage the broader Amateur Radio community for ideas, experiments, and weak
signal ‘home-brew’ experience to help not only the Japanese students’ efforts,
but the potential creation of disruptive technologies that will evolve into
shareware for all of us.”</FONT></P>
<P><FONT face=Tahoma>Vartorella said that FlyVenusCom is intended to serve as an
informal portal or clearing house for dissemination of information for the
Japanese team at Tokyo University, as well as a discussion list of challenges,
innovations and next steps: “There is already shareware available for weak
signal, and the Japanese are proffering support information. This is also a
great opportunity for the CW community worldwide to show off their talents and
innovative ideas. Vartorella said he is especially interested in one-page
research suggestions that can be forwarded to the UNITEC-1 team at Tokyo
University. </FONT></P>

competitions or other approaches on a listserv, may contact Vartorella via
