Selects the displayed frequency shift function from
ON and OFF. (default: OFF)
When this function is activated, the audio pitch or
tones of the received signal will remain the same
even when the operating mode is changed between
SSB and CW.
The amount of frequency shift may differ according
to the CW pitch setting.
• ON
: The displayed frequency shifts when the op-
erating mode is changed between SSB and
CW.
• OFF : The displayed frequency does not shift.
