SATELLITE OPERATION
Both Satellite Mode B (435 MHz uplink, 145 MHz
downlink) and Mode J (145 MHz uplink, 435 MHz
downlink) can be operated with the IC-9100, and
Mode L can be operated when the optional UX-9100

is installed.
Satellite communications is possible only when a sat-
ellite is in view and its transponder is operating.

1.
NEVER
set the output power too high. Too much
power will shorten the satellite’s life.
Set your transmit power so that your downlink sig-
nal level is lower than the beacon’s signal level.
2. Confirm a satellite’s operating mode in advance
through documentation (magazines, etc.) or via ap-
propriate satellite tracking software. In the wrong
mode, you cannot use the satellite, even if you re-
ceive its beacon signal.
3. Preamplifiers may be necessary to receive satel-
lite signals. Optional amplifiers, AG-25, AG-35 and
AG-1200* (for the UX-9100), can be used with the
IC-9100. (p. 71)
* AG-1200 has been discontinued, but it can be still be
used.
4. When you use a reverse tracking satellite in the
SSB mode, use LSB for the uplink frequency and
USB for the downlink frequency.

use USB for both the uplink and downlink frequencies.
Operating frequencies in the satellite mode can be se-
lected either before or after selecting the mode. Nor-
mal and reverse tracking are selectable.

/RBITINFORMATION
Orbit information describes satellite location, reach-
ing angles, etc. This information may be available in
ham magazines or organization publications, such
as those from ARRL, RSGB handbook, etc.
Satellite tracking software is also convenient.
