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.

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 transis­tors. 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

CCAAUUTTIIOONN::

ning using a lightning arrestor.

Protect your transceiver from light-

the antenna tuner. The IC-706MKIIG has an SWR
meter to monitor the antenna SWR continuously.

VFO is an abbreviation of Variable Frequency

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 fre­quency with the main dial and select an operating
mode with the [MODE] switch or call up previously
accessed frequency and modes with the band stack­ing 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

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 coun­terclockwise. 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.

•A segment appears in the S-meter to indicate the S-meter
squelch level.

Narrow filters help reject interference from adjacent

Wide filters provide improved audio for SSB opera­tion when no interfering signals are present.

Consult the table below to select a filter most suitable
for your operating needs.

Narrow filters for AM/FM modes are standard.

The AT-180 automatic antenna tuner matches the IC­706MKIIG to the connected antenna automatically.
Once the tuner matches an antenna, the variable

each frequency range (100 kHz steps). Therefore,
when you change the frequency range, the variable
capacitors are automatically preset to the memorized
point.

During SSB operation on HF bands at low voice lev­els, the AT-180 may not be tuned correctly. In such
cases, manual tuning is helpful.

[TUNER/CALL]

Push and hold for 1 sec. to start

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

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 high­er than 3:1 after tuning.

The transceiver has 105 memory channels (plus 2 call

All 105 memory channels are tuneable which means
the programmed frequency can be tuned temporarily

MEMORY AND SCAN OPERATION

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 initial set mode if desired
(p. 53).

➀

•Push [DISPLAY] 1 or 2 times to select S.

➁ Push [(F-2)MPW] to program the frequency into a

memo pad.

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.

NNoottee::

Each memo pad must have its own unique
combination of frequency and operating mode;
memo pads having identical settings cannot be writ­ten.

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 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.

S2

D

(default)

The tuner operating condition is set by S2
described below.

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 tun­ing 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.

NORMAL CONDITION

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

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-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 instal­lations. The EC recommended limits are almost identi­cal to the FCC specified ‘uncontrolled’ limits and tables
exist that show pre-calculated safe 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 – 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

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

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 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 1–2
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 Direc­tive 1999/5/EC.

This warning symbol indicates that this equip­ment operates in non-harmonised frequency
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.
