ADJUSTING THE TX POWER
Reduce the transmit power as long as you can make a
QSO securely. This prevents you from interfering with or
disturbing other stations.
With this transceiver, you can adjust the transmit power
even while you are transmitting.
1
Rotate the
PWR
control to adjust the transmit power.
Clockwise increases the transmit power and
counterclockwise decreases it. The available transmit power
range varies, depending on the band and operating mode.
Refer to the following table.

TRANSMIT POWER LIMITER
You can place a limit on the transmit power of your
transceiver. This function prevents the transmit power
from exceeding the configured transmit power limit even
with further rotation of the
PWR
control. You can also set a
different
transmit power limit for the DATA mode.
1
Press
[MAX-Po]
(F) to open the
TX Output Limit
screen.

transmit power to be controlled.
As shown below, you can select the item to limit the transmit
power.
Max Power Limit
Transmit power limit for normal transmission.
Max Power Limit (DATA)
Enables the configuration for the transmit power limit while in DATA
Mode.
TX Tune Power
Enables the configuration for the transmit power limit for the
TX Tuning.

Press
[-]
(F6) or
[+]
(F7), or rotate the
MULTI/CH
control to select the limit value for the transmit power.
Press and hold

Press
[MAX-Po]
(F) or
[ESC]
to exit.
Note:
◆
If "On" (with the 5 W transmit power reduction enabled) is
configured in Advanced Menu 08, "TX Power Down with
Transverter Enabled",
[MAX-Po]
(F) on the right side of the main
screen and the wattage value on the key guide will disappear when
the transverter or drive-out is activated.
◆
If ANT1 is selected for the transceiver for use with an external
antenna tuner, the maximum transmit power is limited to 100 W.
Even if greater than 100 W is configured for the transmit limiter, the
display on the key guide of
[MAX-Po]
(F) remains as 100 W as well
as the display on the main screen (100 W).
