Satellite communications outline
Both Satellite Mode B (435 MHz uplink, 145 MHz
downlink), Mode J (145 MHz uplink, 435 MHz
downlink) and Mode L (1270 MHz uplink, 435 MHz
downlink) can be operated.
Preamplifier (user supplied) may help receiving weak
signals.
Satellite information:
Satellite information describes satellite location, orbit
angles, and so on. Such information may be available in
ham magazines, organization publications or on web sites.
Satellite tracking software is also convenient.

• NOR: Both downlink and uplink frequencies
simultaneously increase or decrease in the same
steps when you rotate
• REV:
The downlink frequency follows the tuning dial
rotation, however, the uplink frequency changes in
the reverse direction to the
the same steps.

Questions and answers
Hi I cannot get my ic7900 to work on independe freq and green light sub is on plus I got main rev and sub in my screen .and cannot get my transceiver work with DUB function.on 2 meter please can you help ?
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.
