9 SET MODE
New2001
DD
Offset frequency
Sets the duplex offset frequency for each frequency band in-
dependently within 0 to 159.995 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 frequency in offset frequency above when mon-
itor 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.
DD
Tone squelch
Sets tone or DTCS squelch operation and pocket beep capa-
bility, when waiting for the desired signal.
• OFF : Regular noise squelch operation. (default)
• TSQL : Using tone squelch. The squelch opens only
when a signal with matched subaudible tone
is received.
• P BEEP : In addition to the “TSQL” setting, alert beeps
will sound when a signal with matched tone is
received.
• DTCS : Using DTCS squelch. The squelch opens
only when a signal with matched DTCS code
is received.
• P DTCS : In addition to the “DTCS” setting, alert beeps
will sound when a signal with matched DTCS
code is received.
The subaudible tone frequency and DTCS code is pro-
grammed in the tone frequency and DTCS code item, re-
spectively.
