ter to pick out a receive signal from interference

while the manual notch function is ON.

•Notch ﬁlter center frequency:

SSB : 0 Hz to 5100 Hz

CW : –900 Hz + CW pitch freq. to 4200 Hz + CW

pitch freq.

✔ What is the RIT function?

The RIT (Receiver Incremental Tuning) shifts the receive fre-

quency without shifting the transmit frequency.

This is useful for ﬁne tuning stations calling you on an off-fre-

quency or when you prefer to listen to slightly different-

sounding voice characteristics, etc.

INSTALLATION AND CONNECTIONS

I Unpacking

I Antenna connection

After unpacking, immediately report any damage to the

delivering carrier or dealer. Keep the shipping cartons.

For radio communications, the antenna is of critical im-

portance, along with output power and sensitivity. Se-

lect antenna(s), such as a well-matched 50 Ω antenna,

and feedline. 1.5:1 or better of Voltage Standing Wave

Ratio (VSWR) is recommended for your desired band.

Of course, the transmission line should be a coaxial

cable.

For a description and a diagram of accessory equip-

ment included with the IC-756PROII, see ‘Supplied ac-

cessories’ on p. 1 of this manual.

When using 1 antenna, use the [ANT1] connector.

I Selecting a location

CAUTION: Protect your transceiver from lightning

by using a lightning arrestor.

Select a location for the transceiver that allows ade-

quate air circulation, free from extreme heat, cold, or

vibrations, and away from TV sets, TV antenna ele-

ments, radios and other electro magnetic sources.

PL-259 CONNECTOR INSTALLATION EXAMPLE

The base of the transceiver has an adjustable stand

for desktop use. Set the stand to one of two angles de-

pending on your operating conditions.

I Grounding

To prevent electrical shock, television interference

(TVI), broadcast interference (BCI) and other prob-

lems, ground the transceiver through the GROUND

terminal on the rear panel.

30 mm ≈ ⁹⁄⁸in 10 mm ≈ ³⁄⁸in 1–2 mm ≈ ¹⁄¹⁶in

Antenna SWR

For best results, connect a heavy gauge wire or strap

to a long earth-sunk copper rod. Make the distance be-

tween the [GND] terminal and ground as short as pos-

sible.

Each antenna is tuned for a specified frequency

range and SWR may be increased out-of-range.

When the SWR is higher than approx. 2.0:1, the

transceiver’s power drops to protect the ﬁnal transis-

tor. In this case, an antenna tuner is useful to match

the transceiver and antenna. Low SWR allows full

power for transmitting even when using the antenna

tuner. The IC-756PROII has an SWR meter to mon-

itor the antenna SWR continuously.

RWARNING: NEVER connect the [GND]

terminal to a gas or electric pipe, since the connec-

tion could cause an explosion or electric shock.

VFO is an abbreviation of Variable Frequency Oscilla-

tor, and traditionally refers to an oscillator.

MODE

SWITCHES

The transceiver’s VFO is somewhat different. The VFO

of the IC-756PROII acts like a computer’s window and

can show one frequency and one operating mode.

•Differences between VFO mode and memory mode

VFO MODE

MEMORY MODE (pgs. 51–55)

VFO shows a frequency and operating mode. If the

frequency or operating mode is changed, the VFO

automatically memorizes the new frequency or new

operating mode.

Each memory channel shows a frequency and oper-

ating mode like a VFO. Even if the frequency or mode

is changed, the memory channel does not memorize

the new frequency or operating mode.

When a VFO is selected from another band or mem-

ory mode, the frequency and operating mode last

used for that VFO appear.

When the memory channel is selected from another

memory channel or VFO mode, the memorized fre-

quency and operating mode appear.

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. These controls function as an IF shift control

while in AM mode and when the RTTY ﬁlter is turned

ON. Only the inner control may function in this case.

IF shift is adjustable in 20/40 Hz steps in RTTY (RTTY

ﬁlter is turned ON) or 150/300/500 Hz steps in AM.

I 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 mode.

Current passband width and shift frequency is dis-

played in the ﬁlter set mode screen.

•[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.

➥ To set the [TWIN PBT] controls to the center posi-

tions, push [PBT CLR] for 1 sec.

•While rotating [TWIN PBT], noise may occur. This comes

from the DSP unit and does not indicate an equipment

malfunction.

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

The “P.AMP 2” is most effective when:

•Used on bands above 24 MHz and when electric

ﬁelds are weak.

RECEIVE AND TRANSMIT

I Automatic antenna selection

The transceiver covers 0.1–60 MHz over 10 bands.

Each band key has a band memory which can mem-

orize a selected antenna (ANT1, ANT2, ANT1/RX an-

tenna and ANT2/RX antenna). When you change the

operating frequency beyond a band, the previously

used antenna is automatically selected for the new

band. This function is convenient when you use 2 or 3

antennas.

•Antenna switch selection example

Under the following condition, “Auto” should be se-

lected as the [ANT] switch set mode item.

- When you use 2 antennas.

Under the following conditions, “Manual” should be

selected as the [ANT] switch set mode item.

- When using 1 antenna.

- When using an external antenna selector for more

than 3 antennas (except for receive antenna).

- When using an external antenna tuner.

To use the band memory, enter set mode and conﬁrm

that “Auto” is selected as the [ANT] switch item.

RECEIVE AND TRANSMIT

I Repeater operation

A repeater ampliﬁes received signals and retransmits

them at a different frequency. When using a repeater,

the transmit frequency is shifted from the receive fre-

quency by an offset frequency. A repeater can be ac-

cessed using split frequency operation with the shift

frequency set to the repeater’s offset frequency.

•Setting the repeater tone

Some repeaters require subaudible tones to be ac-

cessed. Subaudible tones are superimposed over

your normal signal and must be set in advance. The

transceiver has 50 tones from 67.0 Hz to 254.1 Hz.

Each memory channel can store an independent set-

ting.

For accessing a repeater which requires a repeater

tone, set the repeater tone frequency in set mode

as described below.

q Select FM mode.

w Push [TONE] for 1 sec. to enter tone set mode.

e Push [(F-1)∫] to select the repeater tone item.

RECEIVE AND TRANSMIT

I Antenna tuner operation

The internal automatic antenna tuner matches the

transceiver to the connected antenna automatically.

Once the tuner matches an antenna, the variable ca-

pacitor 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.

TUNER OPERATION

[TUNER] switch

➥Push the [TUNER] switch to turn the internal an-

tenna tuner ON. The antenna is tuned automati-

cally when the antenna SWR is higher than 1.5:1.

•When the tuner is ON, the [TUNER] switch lights.

MANUAL TUNING

Push [TUNER] for 1 sec.

During SSB operation at low voice levels, the internal

tuner may not be tuned correctly. In such cases, man-

ual tuning is helpful.

➥Push [TUNER] for 1 sec., to start manual tuning.

•A side tone is emitted and [TUNER] 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 func-

tion and turn the tuner OFF. This function activates

the tuner automatically when the SWR exceeds 1.5:1.

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. 70).

NOTES:

•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)

•Tuning a narrow bandwidth antenna

Some antennas, especially for low bands, have a nar-

row bandwidth. These antennas may not be tuned at

the edge of their bandwidth, therefore, tune such an

antenna as follows:

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.

•the power source voltage/capacity.

q Push [TUNER] to turn the antenna tuner ON.

w Select CW mode.

e Turn OFF the break-in function. (p. 5)

r Push [TRANSMIT] to set to the transmit condition.

t Set 3.55 MHz and key down.

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.

y Set 3.80 MHz and key down.

u Push [TRANSMIT] to return to the receive condition.

•adjust the antenna cable length.

(This is effective for higher frequencies in some cases.)

The AH-4/AH-3 matches the IC-756PROII to a long

wire antenna more than 3 m/10 ft long (3.5 MHz and

above) or more than 12 m/40 ft long (1.8 MHz and

above).

•See p. 19 for the transceiver and AH-4/AH-3 connection.

•See the AH-4/AH-3 instruction manual for AH-4/AH-3 in-

stallation and antenna connection details.

•When connecting the AH-4/AH-3, the antenna

connector assignments are [ANT2] for the internal

tuner and [ANT1] for the AH-4/AH-3. The antenna

indicator in the LCD displays “ANT1(EXT)” when

the AH-4/AH-3 is connected and selected.

•The AH-3 can be used for HF bands only. It can-

not be used for the 50 MHz band.

completed, turn the internal tuner ON. Otherwise,

both tuners tune simultaneously and correct tuning

may not be obtained.

MEMORY OPERATION

I Memo pads

The transceiver has a memo pad function to store fre-

The memo pads are separate from memory channels.

Memo pads are convenient when you want to memo-

rize 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.

The default number of memo pads is 5, however, this

can be increased to 10 in set mode if desired. (p. 71)

Use the transceiver’s memo pads instead of relying on

hastily scribbled notes that are easily misplaced.

DC POWER CABLE FUSE REPLACEMENT

If a fuse blows or the transceiver stops functioning, try

to ﬁnd the source of the problem, and replace the dam-

aged fuse with a new, rated fuse.

30 A

fuse

CAUTION:DISCONNECT the DC power cable

from the transceiver when changing a fuse.

The IC-756PROII has 2 types of fuses installed for

transceiver protection.

•DC power cable fuses ................................FGB 30 A

•Circuitry fuse ................................................FGB 5 A

CIRCUITRY FUSE REPLACEMENT

e Replace the circuitry fuse as shown in the diagram

below.

r Replace the PA shielding plate and top cover.

The 13.8 V DC from the DC power cable is applied to

all units in the IC-756PROII, except for the power am-

pliﬁer, through the circuitry fuse. This fuse is installed

in the PA unit.

Circuitry fuse (FGB 5 A)

q Remove the top cover as shown on p. 74.

w Remove 11 screws from the PA shielding plate,

then remove the plate.

I Clock backup battery replacement

The transceiver has a lithium backup battery

(CR2032) inside for clock and timer functions. The

usual life of the backup battery is approximately 2

years.

CR2032

When the backup battery is exhausted, the trans-

ceiver transmits and receives normally but cannot re-

tain the current time.

See p. 78 for battery location.

MAINTENANCE 11

I Tuning dial brake adjustment

The tension of the tuning dial may be adjusted to suit

your preference.

The brake adjustment screw is located on the right

side of the tuning dial. See the ﬁgure at right.

Turn the brake adjustment screw clockwise or coun-

terclockwise to obtain a comfortable tension level

while turning the dial continuously and evenly in one

direction.

I Frequency calibration (approximate)

A very accurate frequency counter is required to cali-

brate the frequency of the transceiver. However, a

rough check may be performed by receiving radio

station WWV, or other standard frequency signals.

u Push [(F-1)Y] several times to select the “Calibra-

tion marker” item.

i Rotate the tuning dial clockwise to turn the calibra-

tion marker ON.

•Side tone may be heard.

CAUTION: Your transceiver has been thor-

oughly adjusted and checked at the factory before

being shipped. You should not calibrate frequen-

cies, except for special reasons.

o Adjust the calibration pot on the right side panel of

the transceiver for a zero beat with the received

standard signal as shown below.

e Set the frequency to the standard frequency sta-

tion minus 1 kHz.

•Zero beat means that two signals are exactly the same

frequency, resulting in a single tone being emitted.

•When receiving WWV (10.000.00 MHz) as a standard

frequency, set the operating frequency for

9.999.00 MHz.
