SET MODE

■Miscellaneous (others) set mode (continued)

QQuuiicckk DDuuaallwwaattcchh

When this item is set to ON, pushing [DUALWATCH]

for 1 sec. sets the sub readout frequency to the main

readout frequency and activates dualwatch operation.

See p. 31 for details.

OONN

Quick dualwatch ON

(default)

OOFFFF

Quick dualwatch OFF

QQuuiicckk SSPPLLIITT

When this item is set to ON, pushing [SPLIT] for 1

sec. sets the sub readout frequency to the main read-

out frequency and activates split operation.

See p. 33 for details.

OONN

Quick split ON

(default)

OOFFFF

Quick split OFF

RRFF//SSQQLL CCoonnttrrooll

The [RF/SQL] control can be set as the RF/squelch

control (default), the squelch control only (RF gain is

ﬁxed at maximum) or ‘Auto’(RF gain control in SSB,

CW and RTTY; squelch control in AM and FM).

See p. 3 for details.

FFMM SSPPLLIITTOOffffsseett((HHFF))

This item sets the offset (difference between transmit

and receive frequencies) for the quick split function.

However, this setting is used for HF bands in FM

mode only and is used to input the repeater offset for

an HF band.

The offset frequency can be set from –4 MHz to

+4 MHz in 1 kHz steps.

--00..110000MMHHzz

Minus 0.1 MHz offset

(default)

--44..000000MMHHzz

Minus 4.0 MHz offset

FFMM SSPPLLIITTOOffffsseett((5500MM))

This item sets the offset (difference between transmit

and receive frequencies) for the quick split function.

However, this setting is used for 50 MHz band FM

mode only, and is used to input the repeater offset for

the 50 MHz band.

The offset frequency can be set from –4 MHz to

+4 MHz in 1 kHz steps.

--00..550000MMHHzz

Minus 0.5 MHz offset

(default)

++44..000000MMHHzz

Plus 4.0 MHz offset

SSPPLLIITT LLOOCCKK

When this item is ON, the tuning dial can be used to

adjust the transmit frequency while pushing [XFC]

even while the lock function is activated.

See p. 32 for split frequency operation details.

OONN

Split lock function ON

OOFFFF

Split lock function OFF
