D D Offset frequency
Sets the duplex offset frequency for each frequency band in-
dependently within 0 to 159.99999 MHz range. During duplex
operation (–DUP or +DUP), the monitoring frequency (while
[SQL] is pushed) shifts the set frequency.
The default value may differ according to the selected fre-
quency band
(before accessing set mode)
The selected tuning step in VFO mode is used for the off-
set frequency setting.
