RECEIVING AND TRANSMITTING
Preampliers
The preamp amplies received signals in the receiver
front end to improve the signal-to-noise ratio and
sensitivity. A preamp is used when receiving weak
signals.
L Each band memorizes the Preamplier setting.
z Touch [P.AMP].
L Touching [P.AMP] selects “P.AMP 1,” “P.AMP 2,” and
“P.AMP OFF.”
P.AMP 1
Wide dynamic range preamplier.
It is most eective for the HF low bands.
• Gain is approximately 12 dB.
P.AMP 2
High-gain preamplier.
It is most eective for the higher bands.
• Gain is approximately 20 dB.
NOTE: When you use the preamp while receiving
strong signals, the receiving signal may be distorted.
In such case, turn OFF the preamp.
Attenuator
The Attenuator prevents a desired signal from
becoming distorted when a very strong signal is near
the frequency, or when a very strong electric eld,
such as from a broadcasting station, is near your
location.
L Each band memorizes the Attenuator setting.
z Touch [ATT] to set the Attenuator up to 18 dB in 6 dB
steps.
You can also set the Attenuator in 3 dB steps:
1. Touch [ATT] for 1 second.
Displayed
2. Rotate
MULTI
to adjust the Attenuator level of
up to 45 dB.
L If a strong signal is received and “OVF” (Overow) is
displayed, turn ON the Attenuator or Digital Selector
function, or decrease the RF gain until “OVF” disappears.
RIT function
The Receiver Incremental Tuning (RIT) function
compensates for dierences in frequencies of other
stations.
The function shifts your receive frequency up to
±9.99 kHz without shifting the transmit frequency.
1. Push
RIT
.
• The RIT function turns ON.
L While using the Fine Tuning function (p. 3-5), the
RIT frequency is displayed in 4 digits, instead of 3.
L Pushing
RIT
turns the RIT function ON or OFF.
2. Rotate
RIT/
TX
to set the RIT frequency to match
the received station’s transmit frequency.
L You can reset the RIT frequency to “0.00” by holding
down
CLEAR
for 1 second.
3. After communicating, push
RIT
to turn OFF the
RIT function.
RIT frequency (3 digits)
D RIT monitor function
When the RIT function is ON, you can directly monitor
the operating frequency by holding down
XFC
.
L While monitoring:
• The RIT function is temporarily turned OFF.
• The Noise Reduction, Notch lter, and Twin PBT
settings are temporarily turned OFF.
