Preparation
q
Decide on a usable satellite, and point your antenna
direction towards it.
w
Confirm the approximate location of the satellite
and operating mode (e.g. “B,” “J,” etc.) through a
publication (magazine, etc.) or an appropriate sat-
ellite tracking software.
e
Push [SATELLITE] to enter the satellite mode.
r
Push [NOR/REV](7 3) to toggle between normal
and reverse tracking.
t
Select the operating mode as listed below.
• To select the operating mode for the uplink, push [SUB]
before selecting the operating mode.

y
Select the desired downlink frequency in the MAIN
band to match the beacon frequency.
• Refer to a ham magazine or book for detailed informa
-
tion.
• Adjust the antenna direction so that the S-meter shows
its strongest level.
• The S-meter level should be noted to adjust transmit
power during a loop test.
u
Perform a loop test.
Loop test procedures
q
Rotate [MAIN DIAL] to select a vacant frequency,
within the satellite’s coverage, as the downlink
frequency on the MAIN band.
w
Push [PTT] on the microphone to transmit. (or
[TRANSMIT] on the transceiver)
e
Push [SUB](3.5 2), then select the uplink fre-
quency on the SUB band while transmitting a
single tone such as a whistle to find your down-
link signal and monitor your own signal correctly.
r
Push [SUB](3.5 2) again after setting.
NOTE:
To avoid excessive power, set the output
power so that the downlink signal strength is lower
than the beacon’s strength.
i
Select the desired frequency to begin your satellite
communications.
• Both the downlink and uplink frequencies change simul
-
taneously.
o
When your downlink audio drifts (Doppler effect),
push [SUB](3.5 2) then rotate [MAIN DIAL] to adjust
the uplink frequency (SUB band).
After adjusting, push [SUB](3.5 2) again.
• When a particular station’s audio is off frequency, use
the RIT function (push [RIT]).

To exit the satellite operation, push [SATELLITE].
✔
For your convenience
As the transceiver has 20 satellite memory channels,
once entered, desired satellite frequencies can be
recalled instantly.
