Setting a tuning step, Setting a frequency | Icom IC-R20 specification

■Setting a tuning step

The tuning step can be selected for each frequency band in- dependently, however, the tuning steps, 8.33 kHz and 9 kHz, only appear when setting the tuning step for the VHF air band and AM broadcast band, respectively. The following tuning

steps are available for the IC-R20.
• 0.01 kHz	• 0.1 kHz	• 1.0 kHz	• 5.0 kHz	• 6.25 kHz
• 8.33 kHz* • 9.0 kHz*		• 10.0 kHz	• 12.5 kHz	• 15.0 kHz
• 20.0 kHz	• 25.0 kHz	• 30.0 kHz	• 50.0 kHz	• 100.0 kHz

* Available for some frequency band only.

DTuning step selection

qPush [VFO MHz] to select VFO mode, if necessary.

wPush [BAND] to select the desired frequency band.

•Or, while pushing and holding [BAND], rotate [R-DIAL]to select the desired frequency band.

eRotate [R-DIAL]to select the desired frequency.

•The frequency changes according to the preset tuning steps. See the left section for setting the tuning step.

•Push [VFO MHz] for 1 sec. then rotate [R-DIAL]to change the frequency in 1 MHz steps, or push for 1 sec. again then rotate [R-DIAL]to change the frequency in 10 MHz steps. (Each push for 1 sec. toggles 1 MHz or 10 MHz tuning steps.)

• Or, while pushing and holding [BAND], rotate [R-DIAL]to select

the desired frequency band.

ePush [9 TS] for 1 sec. to enter tuning step selecting condition. rRotate [R-DIAL]to select the desired tuning step.

tPush [9 TS] to return to VFO mode.
