DX PACKETCLUSTER TUNE
DX PacketCluster is a packet network which consist
of nodes and stations who are interested in DXing
and contesting. If one station finds a DX station on
the air, he or she sends a notice to his or her node.
This node then passes the information to all its local
stations as well as another node. This transceiver
can display received DX information and hold the
latest information on up to 10 DX stations.

SATELLITE OPERATION
It was in December of 1961 when the first Amateur
satellite named OSCAR I was launched. OSCAR
stands for Orbiting Satellite Carrying Amateur Radio.
Since then quite a few of Amateur satellites have
been launched, and about 20 satellites are currently
in orbit serving thousands of hams throughout the
world.

Some Amateur satellites contain transponders that
receive analog signals in one band, amplify them,
shift their frequencies to another band, and retransmit
them. You can enjoy communications in SSB or CW
with other stations via these analog satellites. Most
of them are orbiting at relatively low altitudes and are
called LEOs (Low Earth Orbit).

with other stations via these analog satellites. Most
of them are orbiting at relatively low altitudes and are
called LEOs (Low Earth Orbit).
Amateur satellites receive (uplink) on one band and
transmit (downlink) on another. Different
combinations of uplink and downlink bands are
represented by modes such as A, B, and K. For
example, a Mode K satellite receives on the 21 MHz
band and transmits on the 29 MHz band. This
transceiver can handle the modes listed in the table.

transceiver can handle the modes listed in the table.
In order to work the satellites, you need a rotator that
allows azimuth and elevation control, plus a high-gain
directional antenna. Your antenna has to track
satellites which travel from horizon to horizon.
However, many hams have been successfully using
fixed omnidirectional antennas. If you are using a
directional antenna, it would be wise to obtain a pass
prediction program.

Doppler Shift is another aspect that you must take
into account when working the satellites. As a target
satellite travels away, frequencies on which you will
receive change. This transceiver has a function that
automatically keeps the sum or difference between
the two frequencies identical when you change the
receive frequency.

For further information, consult Internet Web pages
relating to Amateur satellites. On Internet search
engines, use “AMSAT” as key words to find those
Web pages. AMSAT (Radio Amateur Satellite
Corporation) is the world wide organization of
Amateur Satellite operators and supporters. From
AMSAT Web pages, you can also download a variety
of utilities, including pass prediction programs, which
will ease your satellite operations.
