Satellite operation

When your own signal can be received with a loop
test, satellite communication can be performed.
1. Rotate
to set the frequency.
MAIN DIAL
2. When a frequency is shifted by the Doppler effect,
rotate
to tune to the frequency.
MAIN DIAL
• When you use beam antennas, you may need critical
adjustment of the antenna direction, especially when
communicating through satellites in low orbits.
Using the RIT
You can tune the downlink frequency ±9.99 kHz with
the RIT. (p. 4-1)
Communicating in the FM mode:
• Some satellites require the transmit signal with a
tone when communicating in the FM mode. Refer
to amateur radio websites for more information.
• The AFC function automatically compensates for
the frequency drift caused by the Doppler effect. (p.
7-2)
Communicating in the FM mode:
You can have a QSO with the crew of the ISS
(International Space Station) using the Split function. Refer
to related websites for more information.
SATELLITE COMMUNICATION
Satellite memories
The IC-9700 has 99 satellite memories to store both
uplink and downlink frequencies,
operating modes and other data.
L Tracking selection, normal or reverse, is not programmed
in the satellite memories.
L Refer to the ADVANCED MANUAL for memory
management details.

To resolve the issue where the Icom IC-9700 is not working on an independent frequency with the green Sub light on and the Dualwatch (DUB) function not functioning on 2 meters:

1. Confirm Dualwatch is Enabled: Hold down the OFF button for 1 second to turn the Dualwatch function ON. This activates independent monitoring of both Main and Sub bands.

2. Select the Proper Band: Touch the grayed frequency readout to select the active band. Ensure the Main and Sub bands are set to different frequencies and not both on 2 meters, as the same frequency cannot be set on both bands.

3. Check Band Settings: Ensure that the Sub band is not set to the same frequency or band as the Main. The IC-9700 supports independent operation on different bands, but not the same frequency on both Main and Sub.

4. Verify TX is on Main Band: Transmission is only possible on the Main band (except in Split Frequency mode), so ensure the Main band is the one you intend to transmit on.

5. Check for Mode Compatibility: Some functions only apply to the selected band and mode. Confirm that the correct mode (FM, SSB, etc.) is selected for the band in use.

Following these steps should allow independent frequency operation with Dualwatch enabled.
