FUNCTIONS FOR RECEIVE
■ Spectrum scope screen
This function allows you to display the conditions of the
selected band, as well as relative strengths of signals.

FUNCTIONS FOR RECEIVE
■ Preamplifier
The preamp amplifies received signals in the front end
circuit to improve the S/N ratio and sensitivity. Set this
to preamp 1 or preamp 2 when receiving weak signals.
➥ Push [P.AMP] several times to set the preamp OFF,
preamp 1 ON or preamp 2 ON.
[P.AMP]
For all HF bands
High gain preamp for 24 MHz band and
above
✔ About the “P.AMP2”
The “P.AMP 2” is a high gain receive amplifier. When
the “P.AMP 2” is used during times of strong electric
fields, distortion sometimes results. In such cases, use
the transceiver with the “P.AMP 1” or “P.AMP OFF” setting.
The “P.AMP 2” is most effective when:
• Used on bands above 24 MHz and when electric
fields are weak.
• Receive sensitivity is insufficient during low gain, or
while using a narrow band antenna (such as small
loop, a Beverage antenna or a short Yagi antenna,
etc.) is used.
■ Attenuator
The attenuator prevents a desired signal from distortion when very strong signals are near the desired frequency or when very strong electric fields, such as
from broadcasting stations, are near your location.
➥ Push [ATT] several times to set the attenuator 6 dB,
12 dB, 18 dB or attenuator OFF.
➥ Push [ATT] for 1 sec. several times to set the attenuator 3 dB, 6 dB, 9 dB, 12 dB, 15 dB, 18 dB, 21 dB
or attenuator OFF.

FUNCTIONS FOR RECEIVE
■ Twin PBT operation
General PBT (Passband Tuning) function electronically
narrows the IF passband width by shifting the IF frequency to slightly outside of the IF filter passband to
reject interference. This transceiver uses the DSP circuit for the PBT function. Moving both [TWIN PBT]
controls to the same position shifts the IF.
➥ The LCD shows the passband width and shift frequency graphically.
➥ Push [FILTER] for 1 sec. to enter the filter set
screen. Current passband width and shift frequency
is displayed in the filter set screen.
➥ To set the [TWIN PBT] controls to the center positions, push [PBT CLR] for 1 sec.
[TWIN PBT] for main [TWIN PBT] for sub
The variable range depends on the passband width
and mode. The edge of the variable range is half of the
passband width, and PBT is adjustable in 25 or 50 Hz
steps.
[PBT CLEAR] for main [PBT CLEAR] for sub
• [TWIN PBT] should normally be set to the center positions (PBT setting is cleared) when there is no interference.
• When PBT is used, the audio tone may be changed.
• Not available for FM mode.
• While rotating [TWIN PBT], noise may occur. This comes
from the DSP unit and does not indicate an equipment
malfunction.

■ Split frequency operation
Split frequency operation allows you to transmit and
receive in the same mode on two different frequencies.
The split frequency operation is basically performed
using 2 frequencies on the main and sub readouts.
The following is an example of setting 21.290 MHz for
receiving and 21.310 MHz for transmitting.
q Set 21.290 MHz (USB) in VFO mode.
w Push [SPLIT] momentarily, then push [M=S] for
1 sec.

• The quick split function is much more convenient for selecting the transmit frequency. See the next section for
details.
• The equalized transmit frequency and “

• “TX” appears to show the transmit frequency readout.
[XFC] Main dial Sub dial
e Set the transmit frequency to 21.310 MHz with the
one of following ways.
➥ Rotate the main dial while pushing [XFC].
➥ Rotate the sub dial.
• When the split function ON
• The transmit frequency can be monitored while pushing [XFC] or using dualwatch.
r Now you can receive on 21.290 MHz and transmit
on 21.310 MHz.
To change the transmit and receive frequencies, push
[CHANGE] to exchange the main and sub readouts.
• When [XFC] is pushed
✔ CONVENIENT
• Direct shift frequency input
The shift frequency can be entered directly.
q Push [F-INP•ENT].
w Enter the desired shift frequency with the digit keys.
• 1 kHz to 1 MHz can be set.
• When you require a minus shift direction, push [GENE•.]
in advance.
e Push [SPLIT].
• The split frequency operation is ready
• The shift frequency is input in the sub readout and the
split function is turned ON.
[Example]
To transmit on 1 kHz higher frequency:
- Push [F-INP•ENT], [1.8•1] then [SPLIT].
To transmit on 3 kHz lower frequency:
- Push [F-INP•ENT], [GENE•.], [7•3] then [SPLIT].
• Split lock function
Accidentally releasing [XFC] while rotating the main
dial changes the receive frequency. To prevent this,
use both the split lock and dial lock functions to change
the transmit frequency only. The split lock function cancels the dial lock function while pushing [XFC] during
split frequency operation.
The dial lock’s effectiveness during split frequency operation can be selected in the set mode for both receive and transmit frequencies; or only the receive frequency. (p. 12-14)

FUNCTIONS FOR TRANSMIT
■ Quick split function
When you find a DX station, an important consideration is how to set the split frequency.
When you push the [SPLIT] switch for 1 sec., split frequency operation is turned ON, the sub readout is
equalized to the main readout frequency and enters
standby for transmit frequency input.
This shortens the time needed to start split frequency
operation.
The quick split function is ON by default. For your convenience, it can be turned OFF in set mode. (p. 12-14)
In this case, the [SPLIT] switch does not equalize the
main and sub readout frequencies.

• Split frequency operation is turned ON.
• The sub readout is equalized to the main readout frequency.
•“
” indicator appears and the sub readout enters standby for transmit frequency input.
e Enter the desired offset frequency from the keypad
then push [SPLIT], or set the transmit frequency with
the main dial while pushing [XFC], or with the sub
dial.

or the main/sub dial is rotated.
• Offset frequency setting with the keypad— example
To transmit on 1 kHz higher frequency:

To transmit on 3 kHz lower frequency:
- Push [F-INP•ENT], [GENE•.], [7•3] then [SPLIT].
D Split lock function
The split lock function is convenient for changing only
the transmit frequency. When the split lock function is
not used, accidentally releasing [XFC] while rotating the
main dial, changes the receive frequency. The split lock
function is ON by default, but can be turned OFF in set
mode. (p. 12-14)
[LOCK] indicator for main
q While split frequency operation is ON, push [LOCK]
for both main and sub band to activate the split lock
function.
w While pushing [XFC], rotate the main dial to change
