This function is convenient when you operate 3 operating modes on one frequency band. For example, one register can be used for a CW frequency, another for an SSB frequency and the other one for an RTTY frequency. •  he frequency changes in 50 Hz steps when the T [UP]/[DN] switches of the microphone are used for frequency tuning (if the quick tuning function is not selected. ) Touch the Hz digits for 1 second 1 Hz indication 3-9 3 BASIC OPERATION Setting frequency (Continued) (Mode: SSB-D/CW/RTTY) The dial speed is reduced to 1⁄4 of the normal speed when the 1⁄4 tuning function is ON, for finer tuning control.
