Frequencies can be selected with the tuning dial or di-
rectly with the keypad (p. 17). When using the tuning
dial, the frequency changes according to the set tun-
ing step. Tuning step defaults differ depending on op-
erating mode as shown below.
SSB/CW/RTTY: 10 Hz
AM: 1 kHz
FM: 10 kHz
Rotate the tuning dial clockwise to increase the fre-
quency; counterclockwise to decrease the fre-
quency.
When selecting a frequency that lies outside of a
band's specified frequency range, a warning beep
sounds.
This function can be turned off in set mode, if desired
(p. 61).
Tuning steps automatically change according to the
rate at which the tuning dial is rotated.
When rotated slowly, one complete revolution of the
tuning dial changes the frequency 5 kHz (10 Hz tuning
steps); when rotated quickly, one complete revolution
of the tuning dial changes the frequency 25 kHz (50
Hz tuning steps).
Rotate the tuning dial to change the frequency in 10
Hz steps or use the microphone [UP]/[DN] keys to
change the frequency in 50 Hz steps. The diagram
below illustrates how to change the tuning steps.
