15 OPERATOR CONVENIENCES

• If the tuning was successful, “AT ” stops

blinking and the MAIN band red LED turns off.

• If tuning does not finish within approximately

20 seconds, an alarm (“5” in Morse code)

sounds. Press [AT/ ANT1/2] to stop the alarm

and tuning.

If you access Menu No. 27 and select ON, received

signals will also pass through the internal tuner.

When this function is ON, “ ” appears. This may

reduce interference on the receive frequency.

Note:

◆

The internal tuner will not tune outside the available transmission

frequency limits.

◆

Pressing [AT/ ANT1/2] for more than one second while

transmitting, interrupts transmitting and starts tuning.

◆

If you would like to use a separate receiving antenna, access

Menu No. 18 and switch it ON. When this function is ON,

received signals bypass the internal antenna tuner.

◆

While using CW Full Break-in, the internal tuner will be in-line for

both transmitting and receiving.

◆

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 tuner may not retune. This happens because of an SWR

calculation algorithm tolerance between 10 W (approx.) transmit

power for tuning and 100 W transmit power.

◆

If 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.

◆

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

transceiver conditions.

■ Presetting

After each successful tuning session, the AT

Preset memory function stores the position of the

tuning capacitor in the 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/ ANT1/2] momentarily.

•“AT” will appear, showing that the internal

tuner is in-line (not bypassed).

• Each time you go across the antenna tuner

band, the AT 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 50Ω 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.

ATTENUATOR

The attenuator function is useful when extremely

strong signals exist nearby your receiving frequency.

When these type of signals exist nearby your

receiving frequency, the AGC function may be

erroneously controlled by the strong signals, rather

than by the target receiving signal. If this happens,

the target receiving signal can be masked and buried

by the strong signals. In this case, turn the

Attenuator function ON.

1 Press [ATT/ F LOCK].

2 “ATT” appears.

To return to the normal operation, press [ATT/ F LOCK]

again.

Note: If the same band is selected for both the main transceiver and

the sub-receiver, the Attenuator function is on for both receivers.

AUTO MODE

You can configure a maximum of 29 points (HF/

50 MHz), 9 points (144 MHz band), 9 points (430

(440) MHz band), and 9 points (1.2 GHz band) of the

main transceiver VFO (VFO A and B) frequencies to

change the operating mode automatically when you

change the frequency.

As a default, the following modes are programmed on

each operating band.

HF/ 50 MHz band

0.03 ~ 9.5 MHz: LSB

9.5 MHz ~ 60 MHz: USB

144 MHz band

142 ~ 152 MHz: FM

430 (440) MHz band

420 ~ 450 MHz: FM

1.2 GHz band (optional)

1240 ~ 1300 MHz: FM
