MAIN and SUB Bands
The IC-9100 can operate on the HF/50 MHz, 144 MHz,
430 MHz and 1200 MHz* frequency bands. These fre-
quency 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 fre-
quency 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 fre-
quency 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 : Used 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 simulta-
neously, 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.
