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
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
Icom, Icom Inc. and the are registered trademarks of Icom Incorporated (Japan) in the United States, the United Kingdom, Germany, France, Spain, Russia and/or other countries.

TRIPLE BAND STACKING REGISTER
The triple band stacking register provides 3 memories in one band. 3 sets of a frequency and mode on each band are automatically stored when used.
If a band key is pushed once, the frequency and mode last used are called up. When the key is pushed again, another stored frequency and mode are called up.
This function is convenient when you operate 3 modes on one band. For example, one register is used for a CW frequency, another for an SSB frequency and the other one for an RTTY frequency.

■ 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.

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.
q Set 21.290 MHz (USB) in VFO mode.

SPLIT LOCK FUNCTION
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)
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.

24 MHz band and above.
[P.AMP] switch
Regarding the use of the “P.AMP 2”
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.

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
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
•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
r Push [TRANSMIT] to set to the transmit condition. t Set 3.55 MHz and key down.

■ 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.

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
• 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:
ABOUT CE 16
EIRP clearance heights by frequency band
1 | Watts | 2.1 m |
10 | Watts | 2.8 m |
25 | Watts | 3.4 m |
100 Watts | 5 m | |
1000 Watts | 12 m |
Forward clearance, EIRP by frequency band
100 Watts | 2 m |
1000 Watts | 6.5 m |
10,000 Watts | 20 m |
100,000 Watts | 65 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
Similarly some types of transmitter, SSB, CW, AM etc. have a lower ‘average’ output power and the assessed risk is even lower.
