4 BASIC OPERATIONS

Preset

The tuning results can be stored as preset information in the built-
in antenna tuner according to the preset frequency categories.
When the built-in antenna tuner is ON, the preset information that
corresponds to the current TX frequency is automatically
configured for the built-in antenna tuner.
Press [AT].
• << >> appears on the screen. When the antenna
tuner is ON while receiving, <<
preset information that corresponds to the current TX
frequency is configured for the built-in antenna tuner.
• When the TX frequency is altered, the preset information that
corresponds to the preset frequency category is
automatically configured for the built-in antenna tuner.
• To turn off the built-in antenna tuner, press [AT] again.

Holding Transmission at the End of Antenna Tuning

Transmission can be held after antenna tuning has ended.
Configure in Advanced Menu [7] "TX Hold After
Antenna Tuning"
Setting Value Off (default)/ On
Off: Returns to receiving state after antenna tuning has ended.
On: Continues 10 [W] transmission in the CW mode after
antenna tuning has ended.
When transmission is held after antenna tuning has
●
ended, the held status will be canceled when
transmission operations such as [SEND] or PF [DATA
SEND] is performed or when [AT] is pressed.

Switching Antenna Tuner Behavior during Reception

Signals received may be made to pass through the built-in antenna
tuner. Turning ON this function may help to reduce reception
interference from other distant frequencies.
Configure in Advanced Menu [8] "Antenna Tuner
during RX"
Setting Value Off (default)/ On
Off: Signals received do not pass through the built-in antenna
tuner.
On: Signals received pass through the built-in antenna tuner.
When full break-in is ON in the CW mode, the antenna
●
tuner will function during reception regardless of the
above setting.
If the TX and RX frequencies are different during split
●
operation, the antenna tuner will not function during
reception regardless of the above setting.
Configuring the Built-in Antenna Tuner Behavior for
Each Band
Two options to either store the ON/OFF status of the built-in
antenna tuner separately for each band category or to store the
same status for all bands are available.
Configure in Advanced Menu [9] "Antenna Tuner
Operation per Band"
Setting Value Off (default)/ On
Off: Stores the same ON/OFF status of the built-in antenna
tuner for all bands.
On: Stores the ON/OFF status of the built-in antenna tuner for
each band category.

Connecting the External Antenna Tuner AT-300

To use the external antenna tuner AT-300, connect it to the ANT
1 connector and AT connector.
• AT-300 will not function if it is connected to the ANT 2 connector.
AT connector is a control terminal that is used exclusively for
AT-300. It cannot be used to control other external antenna
tuners. When an external antenna tuner other than AT-300 is
connected, make use of TX tuning.
AT-300 cannot be used with the 50/70 MHz band. When
●
using a 50/70 MHz band antenna, connect it to the ANT
2 connector.
When AT-300 is connected to the AT connector and ANT
●
1 is used, the signal bypasses the built-in antenna tuner
circuit.
Production of the AT-300 has been discontinued.
