MEMORY OPERATION
■ Memo pads
The transceiver has a memo pad function to store frequency and operating mode for easy write and recall.
The memo pads are separate from memory channels.
The default number of memo pads is 5, however, this
can be increased to 10 in set mode if desired. (p. 1216)
Memo pads are convenient when you want to memorize a frequency and operating mode temporarily, such
as when you find a DX station in a pile-up, or when a
desired station is busy for a long time and you want to
temporarily search for other stations.
[MP-W] [MP-R]
Use the transceiver’s memo pads instead of relying on
hastily scribbled notes that are easily misplaced.
D Writing frequencies and operating modes into memo pads
You can simply write the accessed readout frequency
and operating mode by pushing [MP-W].
When you write a 6th frequency and operating mode,
the oldest written frequency and operating mode are
automatically erased to make room for the new settings.
Newest
Each memo pad must have its own unique combination of frequency and operating mode; memo
pads having identical settings cannot be written.
Oldest
Erased
In this example, 21.276 MHz (LSB) will be erased
when 7.067 MHz (LSB) is written.
D Calling up a frequency from a memo pad
You can simply call up the desired frequency and operating mode of a memo pad by pushing [MP-R] several times.
• Both VFO and memory modes can be used.
• The frequency and operating mode are called up, starting
from the most recently written.
Newest
When you call up a frequency and an operating mode
from memo pads with [MP-R], the previously displayed
frequency and operating mode are automatically
stored in a temporary pad. The frequency and operating mode in the temporary pad can be recalled by
pushing [MP-R] several times.
Oldest
MEMO PADS
• You may think there are 6 memo pads because 6 different
frequencies (5 are in memo pads and 1 is in the temporary
pad) are called up by [MP-R].
If you change the frequency or operating mode
called up from a memo pad with the main dial, etc.,
the frequency and operating mode in the temporary
pad are erased.

■ Voice squelch control function
This function is useful when you don’t want unmodulated signals pausing or cancelling a scan. When the
voice squelch control function is activated, the receiver
checks received signals for voice components.
If a receiver signal includes voice components, and the
tone of the voice components changes within 1 sec.,
scan pauses (or stops). If the received signal includes
no voice components or the tone of the voice components does not change within 1 sec., scan resumes.
➥ While a phone mode (SSB, AM or FM) is selected,
push [VSC] to switch the VSC (Voice Squelch Control) function ON and OFF.
• “VSC” appears when the function is activated.
• The VSC function activates for any scan.
• The VSC function resumes the scan on unmodulated signals, regardless of whether the scan resume condition is set to ON or OFF.

■ Scan set mode
When the squelch is open, scan continues until it is
stopped manually— it does not pause on detected signals. When squelch is closed, scan stops when detecting a signal, then resumes according to the scan
resume condition. Scan speed and the scan resume
condition can be set using the scan set mode.

ANTENNA TUNER OPERATION
■ Antenna connection and selection
The IC-7800 has 4 antenna connectors for the
HF/50 MHz bands, [ANT1], [ANT2], [ANT3], and
[ANT4].
[ANT]
For each operating band the IC-7800 covers, there is a
band memory which can memorize a selected antenna. When you change the operating frequency beyond a band, the previously used antenna is automatically selected (see below) for the new band. This
function is convenient when you use 4 antennas for HF
and 50 MHz bands operation.
• Antenna selection mode: “Auto”

ANTENNA TUNER OPERATION
10
■ Antenna tuner operation
The internal automatic antenna tuner matches the
transceiver to the connected antenna automatically.
Once the tuner matches an antenna, the variable capacitor angles are memorized as a preset point for
each frequency range (100 kHz steps). Therefore,
when you change the frequency range, the variable capacitors are automatically preset to the memorized
point.
CAUTION: NEVER transmit with the tuner ON when
no antenna is connected. This will damage the
transceiver. Be careful of the antenna selection.
D Tuner operation
➥ Push [TUNER] to turn the internal antenna tuner
ON. The antenna is tuned automatically when the
antenna SWR is higher than 1.5:1.
• When the tuner is ON, the “TUNE” indicator appears.
NOTES:
• NEVER transmit without an antenna properly connected to antenna port in use.
• When 2 or more antennas are connected, select
the antenna to be used with [ANT].
• If the SWR is higher than about 1.5:1 when tuning
above 100 kHz on an antenna’s preset point, push
[TUNER] for 1 sec. to start manual tuning.
• The internal tuner may not be able to tune in AM
mode. In such cases, push [TUNER] for 1 sec. to
manually tune.
[TUNER]
• MANUAL TUNING
During SSB operation at low voice levels, the internal
tuner may not be tuned correctly. In such cases, manual tuning is helpful.
➥ Push [TUNER] for 1 sec., to start manual tuning.
• A side tone is emitted and “TUNE” indicator blinks while
tuning.
• If the tuner cannot reduce the SWR to less than 1.5:1
after 20 sec. of tuning, the [TUNER] switch indicator
goes out.
• AUTOMATIC TUNER START (HF bands only)
If you want to deactivate the tuner under conditions of
VSWR 1.5:1 or less, use the auto tuner start function
and turn the tuner OFF. This function activates the
tuner automatically when the SWR exceeds 1.5:1.
This function is turned ON in set mode. (p. 12-14).

ANTENNA TUNER OPERATION
■ Antenna tuner operation (continued)
• PTT TUNER START
The tuner is always tuned when the PTT is pushed
after the frequency is changed (more than 1% from
last-tuned frequency). This function removes the “push
and hold [TUNER]” operation and activates for the first
transmission on a new frequency.
This function is turned ON in set mode. (p. 12-14).
• Antenna tuner of the IC-PW1
When using an external antenna tuner such as the ICPW1’s tuner, tune with the external antenna tuner,
while the internal tuner is turned OFF. After tuning is
completed, turn the internal tuner ON. Otherwise, both
tuners tune simultaneously and correct tuning may not
be obtained.
See the instruction manual included with each antenna
tuner for their respective operations.
D If the tuner cannot tune the antenna
Check the following and try again:
• the [ANT] connector selection.
• the antenna connection and feedline.
• the unaltered antenna SWR. (Less than 3:1 for HF bands; Less
than 2.5:1 for 50 MHz band)
• the transmit power. (8 W for HF bands; 15 W for 50 MHz band)
• the power source voltage/capacity.
If the tuner cannot reduce the SWR to less than 1.5:1
after checking the above, perform the following:
• repeat manual tuning several times.
• tune with a 50 Ω dummy load and re-tune the antenna.
• turn power OFF and ON.
• adjust the antenna cable length.
(This is effective for higher frequencies in some cases.)
• Some antennas, especially for low bands, have a narrow
bandwidth. These antennas may not be tuned at the edge
of their bandwidth, therefore, tune such an antenna as follows:
[Example]: Suppose you have an antenna which has an
SWR of 1.5:1 at 3.55 MHz and an SWR of 3:1
at 3.8 MHz.
q Push [TUNER] to turn the antenna tuner ON.
w Select CW mode.
e Turn OFF the break-in function. (p. 6-3)
r Push [TRANSMIT] to set to the transmit condition.
t Set 3.55 MHz and key down.
y Set 3.80 MHz and key down.
u Push [TRANSMIT] to return to the receive condition.
