SET MODE
DD
Scope audio output
Sets the audio output function while scope operation.
The scope audio output is used for finding out the signals
while scope function are modulated, unmodulated or beet
signal etc.
DD
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) and receiver version.
The selected tuning step in VFO mode is used for the off-
set frequency setting.
DD
Duplex direction
Sets the duplex direction. The displaying frequency shifts the
programmed offset frequency (at left below) when monitor
function is in use (while pushing [SQL]).
• OFF : Simplex operation. (default)
• –DUP : The displaying frequency shifts down dur-
ing monitor.
• +DUP : The displaying frequency shifts up during
monitor.
