■ Others set mode
Sets the transmission's timing for the HF bands.
When an external device, such as a vacuum tube lin-
ear amplifier or a receiver preamplifier, is connected
to the transceiver and you use the SEND line, a prob-
lem could possibly occur. If the device's transmit/re-
ceive switching time is slower than the time for the
Icom transceiver, the device may not yet ready for
a transmitted signal, and could be damaged by the
transceivers RF power.
If necessary to prevent damage to the external de-
vice, set an appropriate TX delay.
Sets the transmission's timing for the 50 MHz band.
See above TX Delay (HF) for more details.
Turns the Time-Out Timer function ON (3, 5, 10, 20
or 30 minutes) or OFF. If a continuous transmission
exceeds the selected time period, the transmission
will be cut off, to prevent a prolonged transmission.
(default: OFF)
NOTE: This function will be activated only when
you transmit using CI-V commands, or pushing
[TRANSMIT].
When this item is set to ON, holding down [DUAL-
WATCH] for 1 second sets the sub readout frequency
to the main readout frequency and activates dual-
watch operation. (default: ON)
When this item is set to ON, holding down [SPLIT] for
1 second sets the sub readout frequency to the main
readout frequency and activates split operation.
(default: ON)
Sets the offset (difference between transmit and re-
ceive frequencies) for the quick split function. 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 –9.999 MHz to
+9.999 MHz in 1 kHz steps. (default: –0.100 MHz)

• OFF : The transmission delay is disabled.
(default)
• 10 to 30ms: After transmit operation, the TX out-
put is delayed for the set period of time
(10, 15, 20, 25 or 30 milliseconds).
