SATELLITE OPERATION

I Preparation

q Decide on a usable satellite.
w Confirm the approximate location of the satellite and
operating mode (e.g. "B," "J," etc.) through docu-
mentation (magazine, etc.) or via appropriate satel-
lite tracking software.
e Set the antenna direction for the desired satellite.
r Select satellite mode on the transceiver.
• Push [SATELLITE].
• Push [F-INP ENT
ing mode if desired.
t Select operating mode.

con frequency.
• Refer to a ham magazine or book for detailed informa-
tion.
• Adjust the antenna direction so that the S-meter shows
to its strongest level.
• The S-meter level should be noted for transmit power
adjustment during a loop test.

u Perform a loop test.
• Set the downlink frequency (MAIN band) to a vacant fre-
quency within the satellite's coverage.
• Push [SWP 0 Í] then, set the uplink frequency (SUB
band) while transmitting a single tone such as a whistle
to find your downlink signal and monitor your own signal
correctly. Push [SWP 0 Í] after setting.

i Set the desired frequency to begin your satellite
communications.
• Both the downlink and uplink frequencies are changed
simultaneously.
o When your downlink audio drifts (Doppler effect),
push [SWP 0 Í] then rotate the tuning dial to ad-
just the uplink frequency (SUB band) only.
Push [SWP 0 Í] again after setting.
• When a particular station's audio is off frequency, use
the RIT function (push [RIT]).
!0 To exit the satellite operation, push [SATELLITE].
CONVENIENT: As the transceiver has 10 satellite
memory channels, once set, desired satellite fre-
quencies can be recalled instantly.
NOTE: As the downlink (MAIN band) signal is ap-
plied to the SUB band unit in-circuitry in satellite
mode, an optional FL-133
essary to operate CW-N mode.
