•  If the SWR of the antenna system is extremely 

high (more than 10:1), an alarm (“SWR” in 
Morse code) sounds and the internal antenna 
tuner is bypassed.  Before attempting to tune 
again, adjust the antenna system to lower the 
SWR.

4  Monitor the display and check that tuning has 

successfully fi nished.

•  If the tuning was successful, “

” stops 

blinking and the red TX-RX LED turns OFF.

•  If tuning does not fi nish within approximately 

20 seconds, an alarm (“5” in Morse code) 
sounds.  Press [AT (TUNE)] to stop the alarm 
and tuning.

•  If you want the transceiver to stay in 

transmission mode after the tuning completes, 
access Menu No. 57 and select “on”.

•  To pass received signals through the internal 

antenna tuner, access Menu No. 58 and select 
“on”.  When this function is ON, “

” appears.  

This may reduce interference on the receive 
frequency.

◆

  The internal antenna tuner will not tune outside the available 

transmission frequency limits.

◆

 Pressing 

[AT (TUNE)] for more than 1 second while 

transmitting interrupts transmitting and starts tuning.

◆

  While using CW Full Break-in, the internal antenna tuner will 

be in-line for both transmission and reception.

◆

  Tuning automatically turns OFF in approximately 60 

seconds.  “AT” disappears and the error beeps stop.

◆

  Tuning may still continue when the SWR meter indicates 

1:1.  This happens due to the tuning algorithm; this is not a 
malfunction.

◆

  Even 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.

◆

  If tuning does not fi nish even though the SWR meter 

indicates smaller than 3:1, adjust the antenna system to 
lower the SWR, then attempt to tune again.

◆

  Tuning may not reach an SWR of 1:1, depending on the 

transceiver conditions.

◆

  The 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 
combination, then the default data of 50 

 is used.

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 confi gure 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.

0.03 MHz ~ 9.5 MHz: LSB

9.5 MHz ~ 60 MHz: USB

To add the frequency borders to the Auto Mode 
selection:

1  With the transceiver power OFF, press and hold  

[LSB/USB] + [ ] to turn the transceiver ON.

•  “AUTOMODE” appears on the sub-display.

2  Select an Auto Mode frequency memory channel 

number by turning the MULTI/CH control.

•  Auto Memory channels 00 to 31 are available.

3 Turn 

the 

Tuning control to select a desired 

frequency border (or enter the frequency with the 
keypad {page 29}) to change the operating mode.  

4 Press 

[LSB/USB], [CW/FSK (REV)], [FM/AM (FM-

N)], or [DATA] until the desired communication 
mode appears.

5 Repeat 

steps 

2 ~ 4 until you have added all the 

data.

6 Press 

[CLR] to exit the Auto Mode frequency 

confi guration.

To activate the Auto Mode function:

1   Press [MENU], then press [Q-M.IN]/ [Q-MR] or 

turn the MULTI/CH control to select Menu No. 27.

2   Press [M.IN] to select “on”.

3   Press [MENU] to exit Menu mode.

Note:  When using Auto Mode Frequency confi guration, you 
cannot use the Frequency Entry History function.
