Touch the MHz digits. • Band selection screen Enters the Direct input screen Cancel edit Operating mode Example: Touch “21” in the above screen DDUsing the band stacking registers The triple band stacking register provides 3 memories for each band key to store frequencies and operating modes. 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. If a band key or [GENE] is touched for 1 second once, the last used frequency and operating mode are called up. When the key is touched for 1 second again, another stored frequency and operating mode are called up. See the table below for a list of the available frequency bands and their default frequency and mode settings.
