■Spectrum scope screen
This function allows you to display the conditions of the
selected band, as well as relative strengths of signals.
The IC-7800 has two modes for the spectrum indica-
tion— one is center mode, and anther one is fix mode.
In addition, the IC-7800 has a mini scope screen for
regular scope indication.

■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.
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” set-
ting.
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 distor-
tion when very strong signals are near the desired fre-
quency 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 atten-
uator 3 dB, 6 dB, 9 dB, 12 dB, 15 dB, 18 dB, 21 dB
or attenuator OFF.

■AGC function
The AGC (auto gain control) controls receiver gain to
produce a constant audio output level even when the
received signal strength is varied by fading, etc.
The transceiver has 3 AGC characteristics (time con-
stant; fast, mid, slow) for non-FM mode.

(0.1 sec.) and AGC time constant cannot be se-
lected.

■Twin PBT operation
General PBT (Passband Tuning) function electronically
narrows the IF passband width by shifting the IF fre-
quency to slightly outside of the IF filter passband to
reject interference. This transceiver uses the DSP cir-
cuit for the PBT function. Moving both [TWIN PBT]
controls to the same position shifts the IF.
➥The LCD shows the passband width and shift fre-
quency 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 posi-
tions, push [PBT CLR] for 1 sec.
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.
• [TWIN PBT] should normally be set to the center posi-
tions (PBT setting is cleared) when there is no interfer-
ence.
• 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.
qSet 21.290 MHz (USB) in VFO mode.
wPush [SPLIT] momentarily, then push [M=S] for
1 sec.
• The quick split function is much more convenient for se-
lecting the transmit frequency. See the next section for
details.
• The equalized transmit frequency and “ ” ap-
pear on the LCD.
• [SPLIT] indicator lights.
• “TX” appears to show the transmit frequency readout.
eSet the transmit frequency to 21.310 MHz with the
one of following ways.
• When the split function ON ➥Rotate the main dial while pushing [XFC].
➥Rotate the sub dial.
• The transmit frequency can be monitored while push-
ing [XFC] or using dualwatch.
rNow 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.
qPush [F-INP•ENT].
wEnter 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.
• The split frequency operation is ready ePush [SPLIT].
• 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 can-
cels the dial lock function while pushing [XFC] during
split frequency operation.
The dial lock’s effectiveness during split frequency op-
eration can be selected in the set mode for both re-
ceive and transmit frequencies; or only the receive fre-
quency. (p. 12-14)

■Quick split function
When you find a DX station, an important considera-
tion is how to set the split frequency.
When you push the [SPLIT] switch for 1 sec., split fre-
quency 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 con-
venience, 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.
qSuppose you are operating at 21.290 MHz (USB) in
VFO mode.
wPush [SPLIT] for 1 sec.
• Split frequency operation is turned ON.
• The sub readout is equalized to the main readout fre-
quency.
• “ ” indicator appears and the sub readout en-
ters standby for transmit frequency input.
eEnter 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.
• “ ” indicator disappears when [XFC] is pushed
or the main/sub dial is rotated.
• Offset frequency setting with the keypad— 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].
DSplit 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)
qWhile split frequency operation is ON, push [LOCK]
for both main and sub band to activate the split lock
function.
wWhile pushing [XFC], rotate the main dial to change
the transmit frequency.
• If you accidentally release [XFC] while rotating the main
dial, the receive frequency does NOT change.

A maximum message length of 30 sec. can be
recorded into a receive channel and the total message
length of up to 209 sec., and a total message length of
up to 99 sec. can be recorded in transmit channels.
Providing a transmission memory is very convenient

up to 209 sec. can be recorded in receive channels.
However, the maximum recordable length into a

The voice recorder memory records the 30 sec.
(max.) of audio before [REC] is pushed.
For example, when recording 40 sec. of audio,
the first 10 sec. audio will be over-recorded with
the last 10 sec., so that the total of audio recorded
is 30 sec. only.
When you records a 21st audio, or when the total
audio length exceeds 209 sec., the oldest
recorded audio is automatically erased to make
room for the new audio.
