12 SATELLITE OPERATION ■ Satellite communications outline 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 1200 mhz band unit is installed. Satellite communications is possible only when a satellite is in view and its transponder is operating. Orbit information Orbit information describes satellite location, reaching 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. FUJI 3 (FO-29) 145 MHz band 435 MHz band 435 MHz band Uplink Downlink 145 MHz band Mode J operating diagram [Example]: F UJI 3 (FO-29), Mode J Uplink frequency : 145.9000-146.0000 MHz Downlink frequency : 435.8000-435.9000 MHz Tracking direction : Reverse CW beacon frequency : 435.7950 MHz ■ Satellite notes 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 signal level is lower than the beacon's signal level. 2. Confirm a satellite's operating mode in advance through documentation (magazines, etc.) or via appropriate satellite tracking software. In the wrong mode, you cannot use the satellite, even if you receive its beacon signal. 3. Preamplifiers may be necessary to receive satellite 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. • W hen using a normal tracking satellite in SSB mode, use USB for both the uplink and downlink frequencies. ■ Selecting the satellite mode Operating frequencies in the satellite mode can be selected either before or after selecting the mode. Normal and reverse tracking are selectable. D Transferring the VFO frequencies to the satellite VFO q S elect the downlink frequency (receive) in the MAIN band, and the uplink frequency (transmit) in the SUB band. w H old down [SATELLITE] for 1 second to transfer the frequencies, selected in step q, to the satellite VFO. • T he satellite mode is automatically selected after trans- ferring. • " " and the last operated tracking icon (" " or " ") appear. • V FO or Memory mode data is displayed on the SUB band during satellite mode. 153 [SATELLITE]
