This instruction
manual contains important safety and operating
instructions for the IC-706MKIIG.
RWWAARRNNIINNGG HHIIGGHH VVOOLLTTAAGGEE!! NNEEVVEERR
attach an antenna or internal antenna connector dur-
ing transmission. This may result in an electrical shock
or burn.
RNNEEVVEERRapply AC to the [DC13.8V] socket on the
transceiver rear panel. This could cause a fire or ruin
the transceiver.
RNNEEVVEERRapply more than 16 V DC, such as a 24 V
battery, to the [DC13.8V] socket on the transceiver
rear panel. This could cause a fire or ruin the transceiv-
er.
RNNEEVVEERRlet metal, wire or other objects touch any
internal part or connectors on the rear panel of the
transceiver. This will cause electric shock.
RNNEEVVEERRexpose the transceiver to rain, snow or
any liquids.
NNEEVVEERR allow children to play with the transceiver.
AAVVOOIIDD using or placing the transceiver in areas with
temperatures below –10°C (+14°F) or above +60°C
(+140°F). Be aware that temperatures on a vehicle’s
dashboard can exceed 80°C, resulting in permanent
damage to the transceiver’s front panel if left there for
extended periods.
AAVVOOIIDD placing the transceiver in excessively dusty
environments or in direct sunlight.
AAVVOOIIDD placing the transceiver against walls or putting
anything on top of the transceiver. This will obstruct
heat dissipation.
During mobile operation, DDOO NNOOTToperate the trans-
ceiver 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 start-
ing the vehicle. This will avoid possible damage to the
transceiver by ignition voltage spikes.
During maritime mobile operation, keep the transceiv-
er and microphone as far away as possible from the
magnetic navigation compass to prevent erroneous
indications.
BBEE CCAARREEFFUULL!!
The heatsink will become hot when
operating the transceiver continuously for long peri-
ods.
BBEE CCAARREEFFUULL!!If a linear amplifier is connected, set
the transceiver’s RF output power to less than the lin-
ear amplifier’s maximum input level, otherwise, the lin-
ear amplifier will be damaged.
Use Icom microphones only (supplied or optional).
Other manufacturer’s microphones have different pin
assignments and connection to the IC-706MKIIG may
damage the transceiver.
Beat signals may be heard on some frequencies.
These will occur as a result of circuit construction.
For U.S.A. only
CCaauuttiioonn::Changes or modifications to this transceiver, not
expressly approved by Icom Inc., could void your authority
to operate this transceiver under FCC regulations.

For a description and a diagram of accessory equip-
ment included with the IC-706MKIIG, see UNPACK-
ING on p. ii of this manual.
■GGrroouunnddiinngg
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.
For best results, connect a heavy gauge wire or strap
to a long earth-sunk copper rod. Make the distance
between the GROUND terminal and ground as short
as possible.
■AAnntteennnnaa
Select antenna(s), such as a well-matched 50 Ω
antenna, and feedline. The transmission line should
be a coaxial cable. 1.5 : 1 or better of Voltage
Standing Wave Ratio (VSWR) is recommended for

AANNTTEENNNNAA SSWWRR
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-
tors. In this case, an optional 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-706MKIIG has an SWR
meter to monitor the antenna SWR continuously.

FREQUENCY SETTING
■VVFFOO ddeessccrriippttiioonn
VFO is an abbreviation of Variable Frequency
Oscillator, and traditionally refers to an oscillator. The
IC-706MKIIG’s VFO can store a frequency and an
operating mode.
You can call up a desired frequency to a VFO with the
memo pad-read switch (p. 42) or with the memory
transfer switch (p. 42). You can also change the fre-
quency with the main dial and select an operating
mode with the [MODE] switch or call up previously
accessed frequency and modes with the band stack-
ing register (p. 19).
The IC-706MKIIG has two VFOs, specially suited for
split frequency operation. The VFOs are called VFO A
and VFO B. You can use the desired VFO to call up a
frequency and operating mode for operation.

The IC-706MKIIG uses the same control, [RF/SQL],
to adjust one of either the RF gain or the squelch.
[RF/SQL] adjusts either the RF gain or the squelch
depending on the operating mode selected and the
condition of the RF gain item in initial set mode (p. 51;
also see the table at right).
The RF (Radio Frequency) gain is used to adjust the
receiver gain.
•This control should be set to the 11 o’clock position for
normal use.
•Shallow rotation moves the S-meter to the right indicating
the signal strength which can be received.
The SQUELCH removes noise output from the
speaker (closed condition) when no signal is
received. The squelch is particularly effective for FM.
It is also available for the other modes.
•When operating in FM, first rotate the control fully coun-
terclockwise. Then, rotate the control clockwise to the
point where the noise just disappears. This is the best
position. The squelch does not open for weak signals
when it is set too deep.

The AT-180 automatic antenna tuner matches the IC-
706MKIIG 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.
NNoottee::
•The AT-180 cannot be used for the 144/430 MHz
band.
•When operating on the 144/430 MHz band, push-
ing the tuner switch selects the call channel (p. 39).
•The AT-180 can match both HF and 50 MHz bands.
However, operation is different for the HF and 50
MHz bands.

Push and hold [TUNER] to tune the antenna. If the
[TUNER] light flashes slowly while transmitting, push

MMAANNUUAALL TTUUNNIINNGG
During SSB operation on HF bands at low voice lev-
els, the AT-180 may not be tuned correctly. In such
cases, manual tuning is helpful.
Push and hold [TUNER] for 1 sec. to start manual tun-
ing.
•CW mode is selected, a side tone is emitted, and the
[TUNER] light flashes; then, the previous mode is select-
ed.
If the tuner cannot reduce the SWR to less than 1.5:1
after 20 sec. of tuning, the [TUNER] light goes out. In
this case, check the following:
•the antenna connection and feedline
•the antenna SWR (p. 26; meter function)
TThhrroouugghh iinnhhiibbiitt (HF bands only)
The AT-180 has a through inhibit condition. When
selecting this condition, the tuner can be used at
poor SWR’s. In this case, automatic tuning in the HF
bands activates only when exceeding SWR 3:1.
Therefore, manual tuning is necessary each time you
change the frequency. Although termed “through
inhibit,” the tuner will be “through” if the SWR is high-
er than 3:1 after tuning.
•TTuunneerr sseennssiittiivvee ccoonnddiittiioonn (HF bands only)

Split frequency operation allows you to transmit and
receive on two different frequencies. Split frequency
operation uses 2 frequencies, one in VFO A and the
other in VFO B.
Following is an example of setting 7.057 MHz, CW
mode in VFO A (for receive) and 7.025 MHz, CW
mode in VFO B (for transmit).
➀Select VFO A and set the frequency to 7.057
MHz/CW.
•[(F-2)A/B] is available when M1 appears.
•[(F-3)V/M] is available when M2 appears.
➁Push or push and hold [(F-1)SPL] in the M1 dis-
play.
➥Push [SPL]: activates split only.
➥Push and hold [SPL]: activates the quick split
below.
➂To change the receive frequency, rotate the main
dial; to change the transmit frequency, rotate the
main dial while pushing [(F-3)XFC].
•The transmit frequency can be monitored while pushing
[(F-3)XFC].
•Split operation is now set for receive on 7.057 MHz/CW
and transmit on 7.025 MHz/CW.
To exchange the transmit and receive frequencies,
push [(F-2)A/B] in M1.

quency during split frequency operation and [(F-3)Ñ]
allows you to change the transmit frequency.
•SSpplliitt lloocckk ffuunnccttiioonn
The split lock function is convenient for changing
only the transmit frequency. Otherwise, accidentally
releasing the [(F-3)XFC] switch while rotating the
main dial changes the receive frequency. The split
lock’s effectiveness can be selected in initial set
mode (item 12) for both receive and transmit fre-
quencies; or only the receive frequency. (p. 52)

In M1, when you push [(F-1)SPL] for 2 sec., split fre-
quency operation is turned ON and VFO B is auto-
matically changed according to the plus/minus pre-
programmed shift frequency set in initial set mode (or
equalized when 0 kHz is programmed as the split shift
frequency). This shortens the time needed to start
split frequency operation—great for DX’ing.
The quick split function is ON by default. If desired, it
can be turned OFF in initial set mode (p. 51). In this
case, pushing [(F-1)SPL] for 2 sec. has the same
effect as pushing [(F-1)SPL] momentarily as in normal

☞NNOOTTEE:: For packet operation the transceiver can
be set to one of two data speeds: 1200 bps or
9600 bps. Data speed is set in initial set mode (see
p. 54 item 29 9600 MODE).
Data speed is set in initial set mode (see p. 53 item 29
9600 MODE).When setting data transmission
speed to 9600 bps, the
DATA
signal coming from the
TNC is applied exclusively to the internal limiter cir-
cuitry to automatically maintain bandwidth.
NEVER apply data levels from the TNC of over 0.6
Vp-p, otherwise the transceiver will not be able to
maintain the band width and may possibly interfere
with other stations.
☞NNOOTTEE:: Read the instructions supplied with your
TNC carefully before attempting packet operation
with the IC-706MKIIG.
1. When using a level meter or synchroscope, adjust
the TX audio level (
DATA IN
level) from the TNC as
follows.
0.4 Vp-p (0.2 Vrms): recommended level
0.2 Vp-p–0.5 Vp-p (0.1 Vrms–0.25 Vrms):
acceptable level
2. When not using a measuring device.
➀Connect the IC-706MKIIG to a TNC.
➁Enter a test mode (“CAL”, etc.) on the TNC, then
transmit some test data.
➂When the transceiver fails to transmit test data or
transmits sporadically (TX indicator doesn’t appear
or flashes):
Decrease the TNC output level until the transmit
indicator lights continuously.
When transmission is not successful even though
the TX indicator lights continuously:
Increase the TNC output level.

The tuner tunes the antenna even when
the antenna has poor SWR (up to VSWR
3:1 after tuning). In this case, manual tun-
ing is necessary each time you change the
frequency although the tuner automatical-

INSTALLATION NOTES
For amateur base station installations it is recom-
mended that the forwards clearance in front of the an-
tenna 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-field region. 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 Edition 97-01
and its annexes relative to amateur transmitter instal-
lations. The EC recommended limits are almost identi-
cal to the FCC specified ‘uncontrolled’limits and tables
exist that show pre-calculated safe distances for differ-
ent antenna types for different frequency bands. Fur-
ther information can be found at http://www.arrl.org/.
•Typical amateur radio installation
Exposure distance assumes that the predominant ra-
diation 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 con-
stant carrier.
For the bands 10 MHz and higher the following power
density limits have been recommended:
10 – 400 MHz 2 W/sq m
435 MHz 2.2 W/sq m
EIRP Clearance heights by frequency band
Watts 10–2 m 70 cm 23 cm 13cm and above
1 2.1 m 2 m 2 m 2 m
10 2.8 m 2.7 m 2.5 m 2.3 m
25 3.4 m 3.3 m 2.7 m 2.5 m
100 5 m 4.7 m 3.6 m 3.2 m
1000 12 m 11.5 m 7.3 m 6.3 m
Forward clearance, EIRP by frequency band

10,000 20 m 18 m 11 m 7 m
100,000 65 m 60 m 35 m 29 m
In all cases any possible risk depends on the transmit-
ter being activated for long periods. (actual recom-
mendation 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 1–2
minutes 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-706MKIIG which display the
“CE” symbol on the serial number seal, comply
with the essential requirements of the European
Radio and Telecommunication Terminal Direc-
tive 1999/5/EC.
This warning symbol indicates that this equip-
ment operates in non-harmonised frequency
bands and/or may be subject to licensing con-
ditions in the country of use. Be sure to check
