Note:

XThe internal antenna tuner will not tune outside the available transmission frequency limits.

XPressing [AT (TUNE)] for more than 1 second while transmitting interrupts transmitting and starts tuning.

XWhile using CW Full Break-in, the internal antenna tuner will be in-line for both transmission and reception.

XTuning automatically turns OFF in approximately 60 seconds. “AT” disappears and the error beeps stop.

XTuning may still continue when the SWR meter indicates 1:1. This happens due to the tuning algorithm; this is not a malfunction.

XEven though the SWR meter shows more than one segment, the internal antenna tuner may not re-tune. This happens because of an SWR calculation algorithm tolerance.

XIf tuning does not finish even though the SWR meter indicates smaller than 3:1, adjust the antenna system to lower the SWR, then attempt to tune again.

XTuning may not reach an SWR of 1:1, depending on the transceiver conditions.

XThe AT-300 cannot perform tuning on the 50 MHz band.

After each successful tuning session, the internal antenna tuner Preset memory function stores the position of the tuning capacitor in memory. The position of the capacitor is stored for each of the antenna tuner bands (see the following table) and for each antenna connector (ANT 1 and ANT 2).

Press [AT (TUNE)].

•“” or “”appears, showing that the antenna tuner is in-line (not bypassed).

•Each time you go across the antenna tuner band, the internal antenna tuner Preset memory is automatically recalled to position the tuning capacitor without the need for retuning. If no preset data exists for a particular band/ antenna

Note: Tuning may restart in order to obtain the optimum matching condition even though the current antenna tuner band has the preset data.

You can configure a maximum of 32 frequency borders (VFO A and B) to change the operating mode automatically as you change the VFO frequency.

As a default, the following modes are programmed on each operating band.

0.03MHz ~ 9.5 MHz: LSB

9.5MHz ~ 60 MHz: USB

To add the frequency borders to the Auto Mode selection:

1With the transceiver power OFF, press and hold [LSB/USB] + [] to turn the transceiver ON.

• “AUTOMODE” appears on the sub-display.

2Select an Auto Mode frequency memory channel number by turning the MULTI/CH control.

• Auto Memory channels 00 to 31 are available.

3Turn the Tuning control to select a desired frequency border (or enter the frequency with the keypad {page 28}) to change the operating mode.

4Press [LSB/USB], [CW/FSK (REV)], [FM/AM (FM- N)], or [DATA] until the desired communication mode appears.

5Repeat steps 2 ~ 4 until you have added all the data.

6Press [CLR] to exit the Auto Mode frequency configuration.

To activate the Auto Mode function:

1Press [MENU], then press [Q-M.IN]/ [Q-MR]or turn the MULTI/CH control to select Menu No. 23.

2Press [M.IN] to select “on”.

3Press [MENU] to exit Menu mode.

Note: When using Auto Mode Frequency configuration, you cannot use the manual frequency entry function.
