SET MODE
■ Others set mode
Sets the offset (difference between transmit and re-
ceive frequencies) for the quick split function. This set-
ting 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 –9.999 MHz to
+9.999 MHz in 1 kHz steps. (default: –0.500 MHz)
When this item is ON, the main dial can be used to
adjust the transmit frequency while pushing [XFC]
even while the lock function is activated.
(default: OFF)
The internal antenna tuner has an automatic start ca-
pability which starts tuning if the SWR is higher than
1.5–3:1.
Tuning of the internal antenna tuner can be started
automatically at the moment the PTT is pushed after
the operating frequency is changed (more than 1%
from last-tuned frequency). (default: OFF)
Selects the transverter operation condition from Auto
and ON. (default: Auto)
Sets the desired offset frequency for the transverter
operation within 0.000 to 99.999 MHz in 1 kHz steps.
(default: 16.000 MHz)
Selects the RTTY mark frequency. RTTY mark fre-
quency is switched between 1275, 1615 and 2125
Hz. (default: 2125 Hz)
2125 Hz is automatically selected when the internal
RTTY decoder is used.

See pages 6-6, 6-7 for split frequency operation de-
tails.
• OFF : The tuner remains OFF even when the SWR
is poor (1.5–3:1). (default)
• ON : Automatic tune starts even when the tuner is
turned OFF during HF bands operation.
• ON : Turn the transverter operation ON.
• Auto : The transceiver turns into transverter opera-
tion condition when 2 to 13.8 V DC is applied
to [ACC2–A/B] pin 6.
