DScope 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.

DOffset 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.

OFFSET-FREQOFFSET-FREQ

---------------- ----------------

----0.000.00159.999.99

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.

SET MODE 10

DDuplex 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.
