INSTALLATION AND CONNECTIONS
IUnpacking
After unpacking, immediately report any damage to
the delivering carrier or dealer. Keep the shipping car-
tons.
For a description and a diagram of accessory equip-
ment included with the IC-706MKIIG, see UNPACK-
ING on p. ii of this manual.
IGrounding
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.
RWARNING:NEVER connect the [GND] ter-
minal to a gas or electric pipe, since the connection
could cause an explosion or electric shock.
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.
IAntenna
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
your required band. Of course, the transmission line
should be a coaxial cable.
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 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.
CAUTION: Protect your transceiver from lightning
using a lightning arrestor.

The noise blanker reduces pulse-type noise such as
that generated by automobile ignition systems. This
function is not effective for FM modes or for non pulse-
type noise. If you don’t want to use the noise blanker
for AM communications, the “AM noise blanker” item
in Initial Set mode must be turned OFF (ON is the
default setting—p. 53).
➁Push [(F-2)NB] to toggle the noise blanker ON and
OFF.

DPreamp and attenuator
The preamp amplifies received signals in the front
end circuit to improve the S/N ratio and sensitivity.
Turn this function ON when receiving weak signals.
Push [P.AMP/ATT] momentarily to turn the preamp
ON and OFF; push and hold to turn the attenuator ON.
•Lights green when the preamp is ON; lights red when
the 20 dB attenuator is ON.
The attenuator prevents desired signals from distort-
ing when very strong signals are near the desired fre-
quency or when very strong electric fields, such as
from broadcasting stations, are near your location.
•Only one of these functions can be activated at a time.

DOptional AT-180 AUTOMATIC ANTENNA TUNER operation
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.
MANUAL TUNING
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
tuning.
•CW mode is selected, a side tone is emitted, and the
[TUNER] light flashes; then, the previous mode is select-
ed.
CAUTION: NEVER transmit with the tuner ON
when no antenna is connected. This will damage
both the transceiver and the antenna tuner.
[TUNER/CALL]
Note:
•The AT-180 cannot be used for the 144/430 MHz
band.
•When operating on the 144/430 MHz band, pushing
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 for 1 sec. to start
manual tuning.
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)
TUNER OPERATION
•For the HF band:
Through inhibit (HF bands only)
Push [TUNER] to turn the tuner ON. The antenna is
tuned automatically during transmission when the
antenna SWR is higher than 1.5:1.
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.
•When the tuner is OFF, the [TUNER] light goes out.
[TUNER/CALL]
CONVENIENT
Lights to indicate the AT-180
is turned ON.
•Tuner sensitive condition (HF bands only)
If you require critical tuning at any time during trans-
mission, select the tuner sensitive condition. See
p. 55 for selection.
•For the 50 MHz band:
Push and hold [TUNER] to tune the antenna. If the
[TUNER] light flashes slowly while transmitting, push
and hold [TUNER] again to re-tune the antenna.
•Automatic tuner start (HF bands only)
If you want to turn OFF the tuner under conditions of
VSWR 1.5:1 or less, use “automatic tuner on” and
turn the tuner OFF. See p. 54 for turning the function
ON and OFF.

antenna wire is connected to the antenna connector on
the transceiver directly.
NEVER operate the AH-4 without an antenna wire.
The tuner and transceiver will be damaged.
NEVER operate the AH-4 when it is ungrounded.
Transmitting before tuning may damage the trans-
ceiver. Note that the AH-4 cannot tune when using a
1⁄2 λ long wire or multiple of the operating frequency.

DQuick split function
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 nor-
mal split operation.
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.

DRepeater 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
accessed using split frequency operation with the
shift frequency set to the repeater’s offset frequency.
Turn the quick split
function ON.
(Initial set mode default
is ON.)
➀Set the offset frequency and turn ON the quick split
function in initial set mode in advance (p. 52).

DAdjusting the transmit signal output from the TNC
ꢀ NOTE: 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).
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
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.
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 indictor lights continuously:
ꢀ NOTE: Read the instructions supplied with your
TNC carefully before attempting packet operation
with the IC-706MKIIG.
Increase the TNC output level.

MEMORY AND SCAN OPERATION 5
IMemo pads
The transceiver has a memo pad function to store fre-
quency and operating mode for easy write and recall.
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
station is busy for a long time and you want to tem-
porarily search for other stations.
The default number of memo pads is 5, however, this
can be increased to 10 in initial set mode if desired
(p. 53).
Use the transceiver’s memo pads instead of relying on
hastily scribbled notes that are easily misplaced.

THROUGH INHIBIT
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 automatically
starts tuning when the VSWR is higher
than 3:1. This setting is called “through
inhibit,” however, the tuner is set to
“through” if the VSWR is higher than 3:1
after tuning.

TUNER SENSITIVE CONDITION
The tuner tunes each time you transmit
(except SSB mode). Therefore, the lowest
SWR is obtained at any given time.
For SSB mode, the same condition as the
“D” position.

The tuner tunes when the SWR is higher
than 1.5:1. Therefore, the tuner activates

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.
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.
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-
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.
•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.
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
that you have the correct version of this radio or
the correct programming of this radio, to com-
ply with national licensing requirement.
The figures assume the worst case emission of con-
stant carrier.
