INSTRUCTION MANUAL

HF/50 MHz

ALL MODE TRANSCEIVER

i756PRO™

This device complies with Part 15 of the FCC rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation.

IMPORTANT

READ THIS INSTRUCTION MANUAL CAREFULLY before attempting to operate the transceiver.

SAVE THIS INSTRUCTION MANUAL. This manual contains important safety and operating instructions for theIC-756PROII.

EXPLICIT DEFINITIONS

WORD

DEFINITION

Personal injury, fire hazard or electric RWARNING shock may occur.

CAUTION Equipment damage may occur.

If disregarded, inconvenience only. No NOTE risk or personal injury, fire or electric

shock.

RWARNING HIGH VOLTAGE! NEVER attach an antenna or internal antenna connector during transmission. This may result in an electrical shock or burn.

RNEVER apply AC to the [DC13.8V] jack on the transceiver rear panel. This could cause a fire or ruin the transceiver.

RNEVER apply more than 16 V DC, such as a 24 V battery, to the [DC13.8V] jack on the transceiver rear panel. This could cause a fire or ruin the transceiver.

RNEVER let metal, wire or other objects touch any internal part or connectors on the rear panel of the transceiver. This may result in an electric shock.

NEVER expose the transceiver to rain, snow or any liquids.

AVOID using or placing the transceiver in areas with temperatures below–10°C(+14°F) or above +50°C (+122°F). Be aware that temperatures on a vehicle’s dashboard can exceed 80°C (+176°F), resulting in permanent damage to the transceiver if left there for extended periods.

AVOID placing the transceiver in excessively dusty environments or in direct sunlight.

AVOID placing the transceiver against walls or putting anything on top of the transceiver. This will obstruct heat dissipation.

Place unit in a secure place to avoid inadvertent use by children.

During mobile operation, DO NOT operate the transceiver without running the vehicle’s engine. When transceiver power is ON and your vehicle’s engine is OFF, the vehicle’s battery will soon become exhausted.

Make sure the transceiver power is OFF before starting the vehicle. This will avoid possible damage to the transceiver by ignition voltage spikes.

During maritime mobile operation, keep the transceiver and microphone as far away as possible from the magnetic navigation compass to prevent erroneous indications.

BE CAREFUL! The heatsink will become hot when operating the transceiver continuously for long periods.

BE CAREFUL! If a linear amplifier is connected, set the transceiver’s RF output power to less than the linear amplifier’s maximum input level, otherwise, the linear amplifier will be damaged.

Use Icom microphones only (supplied or optional). Other manufacturer’s microphones have different pin assignments, and connection to the IC-756PROIImay damage the transceiver.

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.

What is the PBT control?

General PBT function electronically narrows the IF passband width to reject interference. This transceiver uses the DSP circuit for the PBT function.

3 INSTALLATION AND CONNECTIONS

Unpacking

Antenna connection

After unpacking, immediately report any damage to the delivering carrier or dealer. Keep the shipping cartons.

For a description and a diagram of accessory equipment included with the IC-756PROII,see ‘Supplied accessories’ on p. 1 of this manual.

Selecting a location

Select a location for the transceiver that allows adequate air circulation, free from extreme heat, cold, or vibrations, and away from TV sets, TV antenna elements, radios and other electro magnetic sources.

The base of the transceiver has an adjustable stand for desktop use. Set the stand to one of two angles depending on your operating conditions.

Grounding

To prevent electrical shock, television interference (TVI), broadcast interference (BCI) and other problems, ground the transceiver through the GROUND terminal on the rear panel.

For best results, connect a heavy gauge wire or strap to a long earth-sunkcopper rod. Make the distance between the [GND] terminal and ground as short as possible.

RWARNING: NEVER connect the [GND]

terminal to a gas or electric pipe, since the connec- tion could cause an explosion or electric shock.

For radio communications, the antenna is of critical importance, along with output power and sensitivity. Select antenna(s), such as a well-matched50 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.

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

CAUTION: Protect your transceiver from lightningby using a lightning arrestor.

Antenna SWR

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 transistor. 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. TheIC-756PROIIhas an SWR meter to monitor the antenna SWR continuously.

4 FREQUENCY SETTING

VFO description

VFO is an abbreviation of Variable Frequency Oscillator, and traditionally refers to an oscillator.

The transceiver’s VFO is somewhat different. The VFO of the IC-756PROIIacts like a computer’s window and can show one frequency and one operating mode.

You can call up a desired frequency to the VFO with the keypad, memo pad-readswitch (see p. 56) or the memory transfer function (see p. 54). You can also change the frequency with the tuning dial and select the operating mode with the mode switches.

During dualwatch or split frequency operation, the sub VFO is functional (non-outline,non-spotted,larger frequency characters). While pushing [XFC] during split frequency operation, you can change the transmit readout frequency with the keypad, memopad-readswitch or the memory transfer function.

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 mode. Current passband width and shift frequency is displayed in the filter set mode screen.

To set the [TWIN PBT] controls to the center positions, 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. 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.

• [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.

Accidentally releasing the [XFC] switch while rotating the tuning 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. 69)

[P.AMP] switch

Regarding the use of the “P.AMP 2” (Pre-amplifier2)

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.

5 RECEIVE AND TRANSMIT

Digital voice recorder

The transceiver has a total of 8 memory channels, 4 each for transmit and receive, of digital voice memories. A maximum message length of 15 sec. can be recorded in each receive channel, and a total message length of 90 sec. can be recorded in transmit channels.

Providing a transmission memory is very convenient for repeated CQ and number transmissions at contest times, as well as when making consecutive calls in DX’pedition.

Automatic antenna selection

The transceiver covers 0.1–60MHz over 10 bands. Each band key has a band memory which can memorize a selected antenna (ANT1, ANT2, ANT1/RX antenna 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.

To use the band memory, enter set mode and confirm that “Auto” is selected as the [ANT] switch item. (p. 70)

• Antenna switch selection example

Under the following condition, “Auto” should be selected 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.

A repeater amplifies received signals and retransmits them at a different frequency. When using a repeater, the transmit frequency is shifted from the receive frequency by an offset frequency. A repeater can be accessed using split frequency operation with the shift frequency set to the repeater’s offset frequency.

For accessing a repeater which requires a repeatertone, set the repeater tone frequency in set modeas described below.

qSet the offset frequencies (HF, 50 MHz) and turn ON the quick split function in set mode (others) in advance. (p. 69)

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.

RECEIVE AND TRANSMIT

5

CAUTION: NEVER transmit with the tuner ON

when no antenna is connected. This will damagethe transceiver. Be careful of the antenna selection.

TUNER OPERATION

Push the [TUNER] switch 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 [TUNER] switch lights.

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 [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 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. 70).

PTT TUNER START

The tuner is always tuned when the PTT is pushed after the frequency is changed (more than 1% from last-tunedfrequency). 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)

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-tunethe antenna.

turn power OFF and ON.

adjust the antenna cable length.

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

• Tuning a narrow bandwidth antenna

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:

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-infunction. (p. 5)

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.

RWARNING: HIGH VOLTAGE!

NEVER touch the antenna element while tuningor transmitting.

NEVER operate theAH-4/AH-3without an antenna wire. The tuner and transceiver will be damaged.

NEVER operate theAH-4/AH-3when it is not grounded.

Transmitting before tuning may damage the transceiver. Note that the AH-4/AH-3cannot tune when using a12 λ long wire or multiple of the operating frequency.

eThe [TUNER] light lights constantly when tuning is complete.

When the connected wire cannot be tuned, the [TUNER] light goes out and the AH-4/AH-3is bypassed. At that point the antenna wire connection rout is to the transceiver directly, and not via theAH-4/AH-3antenna tuner.

r To bypass the AH-4/AH-3manually, push [TUNER].

• ANTENNA TUNER OF THE IC-PW1

When using an external antenna tuner such as the IC-PW1’stuner, 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.

Memory channels

The transceiver has 101 memory channels. The memory mode is very useful for quickly changing to oftenused frequencies.

All 101 memory channels are tuneable which means the programmed frequency can be tuned temporarily with the tuning dial, etc. in memory mode.

Frequency transferring can be performed in either VFO mode or memory mode.

• Transferring in VFO mode

This is useful for transferring programmed contents to VFO.

q Select VFO mode with [VFO/MEMO].

wSelect the memory channel to be transferred with [Y]/[Z].

Memory channel screen is convenient for selecting the desired channel.

Memory channel contents appear in the memory chan-

nel readout (below the frequency readout).

•“--.---.--”appears if the selected memory channel is a blank channel. In this case transferring is impossible.

ePush [VFO/MEMO] for 1 sec. to transfer the frequency and operating mode.

Transferred frequency and operating mode appear on the frequency readout.

• Transferring in memory mode

This is useful for transferring frequency and operating mode while operating in memory mode.

When you have changed the frequency or operat-

ing mode in the selected memory channel:

Displayed frequency and mode are transferred.

Programmed frequency and mode in the mem-

Icom

ory channel are not transferred, and they remain in the memory channel.

qSelect the memory channel to be transferred with [Y]/[Z] in memory mode.

And, set the frequency or operating mode if required. w Push [VFO/MEMO] for 1 sec. to transfer the fre-

quency and operating mode.

Displayed frequency and operating mode are transferred to the VFO.

eTo return to VFO mode, push [VFO/MEMO] momentarily.

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. 71)

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.

Use the transceiver’s memo pads instead of relying on hastily scribbled notes that are easily misplaced.

• 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.

Each memo pad must have its own unique combi-nation of frequency and operating mode; memopads having identical settings cannot be written.

• 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.

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.

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 tuning dial,

etc., the frequency and operating mode in the tem-porary pad are erased.

Preparation

• Channels

For programmed scan:

Program scan edge frequencies into scan edge memory channels P1 and P2.

For ∂F scan:

Set the ∂F span (∂F scan range) in the scan screen.

For memory scan:

Program 2 or more memory channels except scan edge memory channels.

For select memory scan:

Designate 2 or more memory channels as select memory channels. To designate the channel as a select memory channel, choose a memory channel, then push [(F-3)SELECT]in the scan screen (memory mode) or in the memory channel screen.

• Scan resume ON/OFF

You can select the scan to resume or cancel when detecting a signal, in set mode. Scan resume ON/OFF must be set before operating a scan. See p. 61 for ON/OFF setting and scan resume condition details.

• Scan speed

Scan speed can be selected from 2 levels, high or low, in set mode. See p. 61 for details.

Fuse replacement

If a fuse blows or the transceiver stops functioning, try to find the source of the problem, and replace the damaged fuse with a new, rated fuse.

CAUTION: DISCONNECT the DC power cablefrom the transceiver when changing a fuse.

The IC-756PROIIhas 2 types of fuses installed for

transceiver protection.

• DC power cable fuses ................

FGB 30 A

• Circuitry fuse ........................

FGB 5 A

CIRCUITRY FUSE REPLACEMENT

The 13.8 V DC from the DC power cable is applied to all units in the IC-756PROII,except for the power amplifier, through the circuitry fuse. This fuse is installed in the PA unit.

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

wRemove 11 screws from the PA shielding plate, then remove the plate.

eReplace the circuitry fuse as shown in the diagram below.

r Replace the PA shielding plate and top cover.

Circuitry fuse (FGB 5 A)

Clock backup battery replacement

The transceiver has a lithium backup battery

(CR2032) inside for clock and timer functions. The

CR2032

usual life of the backup battery is approximately 2

years.

When the backup battery is exhausted, the transceiver transmits and receives normally but cannot retain the current time.

See p. 78 for battery location.

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 counterclockwise to obtain a comfortable tension level while turning the dial continuously and evenly in one direction.

Frequency calibration(approximate)

A very accurate frequency counter is required to calibrate the frequency of the transceiver. However, a rough check may be performed by receiving radio station WWV, or other standard frequency signals.

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. q Push [SSB] to select USB mode.

wPush [PBT CLR] for 1 sec. to clear the PBT settings and make sure that the RIT/∂TX function is not activated.

eSet the frequency to the standard frequency station minus 1 kHz.

When receiving WWV (10.000.00 MHz) as a standard frequency, set the operating frequency for 9.999.00 MHz.

Other standard frequencies can also be used.

INSTALLATION NOTES

For amateur base station installations it is recommended that the forwards clearance in front of the antenna array is calculated relative to the EIRP (Effective Isotropic Radiated Power). The clearance height below the antenna array can be determined in most cases from the RF power at the antenna input terminals.

As different exposure limits have been recommended for different frequencies, a relative table shows a guideline for installation considerations.

Below 30 MHz, the recommended limits are specified in terms of V/m or A/m fields as they are likely to fall within the near-fieldregion. Similarly, the antennae may be physically short in terms of electrical length and that the installation will require some antenna matching device which can create local, high intensity magnetic fields. Analysis of such MF installations is best considered in association with published guidance notes such as the FCC OET Bulletin 65 Edition97-01and its annexes relative to amateur transmitter installations. The EC recommended limits are almost identical to the FCC specified ‘uncontrolled’ limits and tables exist that showpre-calculatedsafe distances for different antenna types for different frequency bands. Further information can be found at http://www.arrl.org/.

• Typical amateur radio installation

Exposure distance assumes that the predominant radiation pattern is forwards and that radiation vertically downwards is at unity gain (sidelobe suppression is equal to main lobe gain). This is true of almost every gain antenna today. Exposed persons are assumed to be beneath the antenna array and have a typical height to 1.8 m.

The figures assume the worst case emission of constant carrier.

For the bands 10 MHz and higher the following power density limits have been recommended:

10–50MHz 2 W/sq m

In all cases any possible risk depends on the transmitter being activated for long periods. (actual recommendation limits are specified as an average during 6 minutes) Normally the transmitter is not active for long periods of time. Some radio licenses will require that a timer circuit automatically cuts the transmitter after 1–2minutes etc.

Similarly some types of transmitter, SSB, CW, AM etc. have a lower ‘average’ output power and the assessed risk is even lower.

Versions of the IC-756PROIIwhich display the “CE” symbol on the serial number seal, comply with the essential requirements of the European Radio and Telecommunication Terminal Directive 1999/5/EC.

This warning symbol indicates that this equipment operates in non-harmonisedfrequency bands and/or may be subject to licensing conditions in the country of use. Be sure to check that you have the correct version of this radio or the correct programming of this radio, to comply with national licensing requirement.
