Icom IC-9100 Instruction Manual - Page 41

3 BASIC OPERATION ■ MAIN and SUB Bands The IC-9100 can operate on the HF/50 MHz, 144 MHz, 430 MHz and 1200 MHz* frequency bands. These frequency bands can be assigned to the MAIN and SUB Bands for operating convenience. The frequency band, selected in either the MAIN or SUB Band, cannot be selected on the other Band. For example, if the MAIN Band is set to operate on any frequency within the HF/50MHz band, the SUB Band can simultaneously receive on only the 144 MHz, 430 MHz and 1200 MHz* frequency bands, or visa versa. *The optional UX-9100 is required for the 1200 MHz frequency band operation. Both MAIN and SUB Bands have independent features. MAIN Band : Used for both transmitting and receiving. The MAIN Band area is in the upper half of the LCD display. SUB Band : U sed for only receiving. The SUB Band area is in the lower half of the LCD display. About transmitting You can transmit on only the MAIN Band- not on the SUB Band. However, while operating in the Satellite mode, you can transmit on the SUB Band. D MAIN/SUB Band selection The LCD display shows both the MAIN and SUB Band frequencies. Both Bands can receive signals simultaneously, but not on the same frequency band. Set the frequency band you want to transmit or be called on, as the MAIN Band. ➥ Push [MAIN/SUB] to toggle the MAIN and SUB Bands.
