TX Delay (Default: All bands; OFF)
Function > TX Delay (TX Delay)
Sets the transmission’s timing for each operating
band.
When an external device, such as a vacuum tube linear
amplifier or a receiver preamplifier, is connected to the
transceiver and you use the SEND line, a problem could
possibly occur. If the device’s transmit/receive switch-
ing 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 device,
set an appropriate TX delay.
• OFF: The transmission delay is disabled.
• 10 to 30ms: After pushing [PTT], the transmission is
delayed for the set period of time (10, 15,
20, 25 or 30 milliseconds).
Time-Out Timer (Default: OFF)
Function > Time-Out Timer (Time-Out Timer)
To prevent accidental prolonged transmission, the
transceiver has a time-out timer.
The function inhibits continuous transmissions longer
than the set time period.
• OFF: Turns the function OFF.
• 3 to 30 min: The transmission is cut OFF after the set
time period ends (3, 5, 10, 20 or 30 min-
utes).
PTT Lock (Default: OFF)
Function > PTT Lock (PTT Lock)
Turn the PTT lock function ON and OFF.
To prevent accidental transmissions, this function dis-
ables [PTT].
Quick SPLIT (Default: ON)
Function > SPLIT/DUP > Quick SPLIT (Quick SPLIT)
Turn the Quick Split function ON or OFF.
When this item is set to ON, hold down [SPLIT] for 1
second to shift the transmit frequency from the receive
frequency, according to the “SPLIT Offset” option as
described to the right.
• OFF: Turns the function OFF.
• ON: Holding down [SPLIT] for 1 second quickly se-
lects split frequency operation.
SPLIT Offset (Default: 0.000 MHz)
Function > SPLIT/DUP > SPLIT Offset (SPLIT Offset)
Set the offset* for the quick split function.
*The difference between transmit and receive frequencies.
The frequency offset can be set to between –9.999
MHz and +9.999 MHz in 1 kHz steps.
SPLIT LOCK (Default: OFF)
Function > SPLIT/DUP > SPLIT LOCK (SPLIT LOCK)
Turn the Split Lock function ON or OFF.
When this item is set to ON, you can use the Dial to
adjust the transmit frequency while holding down
,
even while the Dial Lock function is enabled.
To prevent accidentally changing the receive frequency
by rotating the main dial, use both the SPLIT LOCK
and Dial Lock functions.
See pages 6-8 to 6-10 for split frequency operation de-
tails.
DUP Offset
Function > SPLIT/DUP > DUP Offset (DUP Offset)
Set the offset* for duplex operation. You can set the re-
peater offset for each band.
*The difference between transmit and receive frequencies.
Before selecting this item, select the desired fre- ➥
quency band. Then, set the offset.
• The frequency offset can be set to between 0.0000 MHz
and 9.9999 MHz.
The default value may differ, depending on the se-
lected frequency band and transceiver version.
NOTE:
• The shift direction can be set with [DUP] on M1 (M1
Menu) screen.
• You can use this setting only when the Split function
is OFF.
• If the DR mode is selected before selecting this
item, editing is restricted.
One Touch Repeater (Default: DUP–)
Function > SPLIT/DUP > One Touch Repeater (One
Touch Repeater)
Set the one touch repeater shift direction.
• DUP–: The transmit frequency shifts down from the
receive frequency by the offset amount.
• DUP+: The transmit frequency shifts up from the re-
ceive frequency by the offset amount.
