To prevent electrical shock, television interference

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

You can call up a desired frequency to a VFO with the

The IC-706MKIIG has two VFOs, specially suited for
split frequency operation. The VFOs are called VFO A

When neither the quick tuning step or programmable
tuning step, “Z,” appear, rotating the main dial
changes the frequency in increments of 1 or 10 Hz.
These tuning steps are only available in SSB, CW
and RTTY modes.
➀ Select SSB, CW or RTTY mode if necessary.
➁ Push [TS] for 2 sec. to toggle between the 1 and
17
10 Hz step settings.
•When the 1 Hz step is selected, the 1 Hz digit appears
in the frequency indication; when the 10 Hz step is
selected, the 1 Hz digit disappears from the frequency
indication.

The sub dial function allows you to change the operating frequency using the [M-CH] control. This gives
you more control in tuning since the [M-CH] knob is
detented—each click changes the frequency
according to the set tuning step. This function is
always available in FM, WFM and AM modes.
However, in SSB, CW and RTTY modes, the set
mode item “Sub dial function,” must be set to “FrEq.”
➀ Push [RIT/SUB] to turn the sub dial function ON.
•The [SUB] indicator lights green; if it lights red, the RIT
function is activated—sub dial function must be set in
initial set mode in this case.
➁ Rotate [M-CH] to change the operating frequency
according to the set tuning steps.
➂ Push [RIT/SUB] again to turn the function OFF.
•The [SUB] indicator turns off.

The quick band change function automatically stores
the last frequency and mode used for each band in a
band stacking register. This is convenient for contest
operation, etc. The tables below show the quick
band change default settings for each band.
➀ Select S3.
•Push [DISPLAY] when M or G is displayed.
•Push [MENU] twice to select S3.
➁ Push [F-1]–[F-3] to select a band stacking register.
•The default settings for [F-1]–[F-3] are 7, 144 and 430
MHz bands, respectively.
➂ To change the settings for [F-1]–[F-3] from their
defaults, push [F-1]–[F-3] for 1 sec. one or more
times to until the desired band appears in the display above the corresponding switch.
•The last-used frequency and mode for the selected
band are displayed.

The IF shift function electronically changes the passband frequency of the IF (intermediate frequency)
and cuts out higher or lower frequency components
of the IF to reject interference. The function shifts the
IF frequency up to ±1.2 kHz in 15 Hz steps in
SSB/CW/RTTY modes and up to ±250 Hz in 3 Hz
steps in CW-ã/RTTY-ã modes. The IF shift is not
available in FM and AM modes.
➀ Adjust the [SHIFT] control for a minimum interfer-
ence signal level.
•The audio tone may be changed while the IF shift is in
use.
➁ Set the shift control to its center position when
there is no interference.

The RIT (Receive Incremental Tuning) function compensates for off-frequencies of communicating stations. The function shifts the receive frequency up to
±9.99 kHz in 10 Hz steps without moving the transmit
frequency. The [SUB/RIT] switch in Initial Set Mode
must be set to RIT mode in advance (p. 51).
➀ Push [RIT].
•The [RIT] indicator lights red.
➁ Rotate the [M-CH] control to cancel the off-fre-
quencies.
•The transmit frequency is not shifted.
➂ To cancel the RIT function, push [RIT] again.
•The [RIT] switch indicator goes out.
