4 BASIC OPERATIONS Frequency Adjustment Using the [MULTI/CH] Control Turning the [MULTI/CH] control enables the frequency to be changed quickly. The frequency increases or decreases in increments based on the configured step size. Turn the [MULTI/CH] control to increase or decrease the frequency. The default frequency per step is 1 kHz in the SSB mode, 0.5 kHz in the CW/ FSK/ PSK mode, 5 kHz in the AM mode and 10 kHz in the FM mode. Switching the AM Broadcast Frequency in 9 kHz Steps In the BC band (medium frequency band) from 522 kHz to 1710 kHz and LF band (long frequency band) from 153 kHz to 279 kHz, the RX frequency can be adjusted in steps of 9 kHz by turning the [MULTI/CH] control. Configure in Menu [3-05] "9 kHz Step in AM Broadcast Band (Multi/Channel Control)" Setting Value Off (K type: default)/ On (E type: default) Rounding the Frequency When the frequency is adjusted by turning the [MULTI/CH] control, the new frequency is automatically rounded to the integer multiple of the step size. Rounding of the frequency can also be disabled. Configure in Menu [3-00] "Frequency Rounding Off (Multi/Channel Control)" Setting Value Off/ On (default) Configuring the Frequency Step Size of the [MULTI/CH] Control The frequency per step when the [MULTI/CH] control is turned can be configured or changed to a different value for each mode. SSB Mode Configure in Menu [3-01] "SSB Mode Frequency Step Size (Multi/Channel Control)" Setting Value 0.5/ 1 (default)/ 2.5/ 5/ 10 [kHz] CW/ FSK/ PSK Mode Configure in Menu [3-02] "CW/FSK/PSK Mode Frequency Step Size (Multi/Channel Control)" Setting Value 0.5 (default)/ 1/ 2.5/ 5/ 10 [kHz] FM Mode Configure in Menu [3-03] "FM Mode Frequency Step Size (Multi/Channel Control)" Setting Value 5/ 6.25/ 10 (default)/ 12.5/ 15/ 20/ 25/ 30/ 50/ 100 [kHz] AM Mode Configure in Menu [3-04] "AM Mode Frequency Step Size (Multi/Channel Control)" Setting Value 5 (default)/ 6.25/ 10/ 12.5/ 15/ 20/ 25/ 30/ 50/ 100 [kHz] . Adjusting Frequency in MHz Steps The frequency can be adjusted in units of MHz. 1 Press [MHz]. Pressing [MHz] each time toggles the MHz step function between ON and OFF. When the function is turned ON, > lights up. 2 Turn the [MULTI/CH] control while the function is turned ON. The frequency increases or decreases according to the MHz frequency step configured in Menu [3-06]. Configuring the Frequency Step Size in MHz Configure in Menu [3-06] "MHz Step" Setting Value 100/ 500/ 1000 (default) [kHz] Direct Input of Frequency Value If the desired frequency is far apart from the current frequency value, the fastest way is to input the frequency value directly using the numeric keypad. 1 Press [ENT]. A screen to input the frequency for the operable band appears with all the frequency digits displayed as "-". 4-6
