RECEIVE AND TRANSMIT

The IC-706MKIIG can measure SWR in 2 ways:
(A) Spot measurement; or (B) Plot measurement.

➀

Confirm that the output power is over 30 W.

➁

Push [MENU] one or more times to select 

M3

.

➂

Push [

(F3)

MET

] to select the SWR meter.

➃

Push [MODE] one or more times to select CW or
RTTY operation.

• Key down or push [PTT] to transmit; then read the actu-

al SWR from the meter:

➠

≤

1.5 well matched antenna

➠

>

1.5 check antenna or cable connection, etc.

(B) Plot measurement
Plot measurement allows you to measure the SWR
over an entire band.

q

Confirm that the output power is over 30 W.

w

Push [DISPLAY] twice to select 

G1

.

e

Push [MENU] to select 

G2

.

r

Set the center frequency for the SWR to be mea-
sured.

t

Push and hold [

(F1)

10k

] one or more times to

select the desired frequency pitch.

y

Push and hold [

(F2)

] one or more times to select

the desired step.

u

After selecting the desired pitch and step, push
[

(F3)

STR

] to measure the SWR.

i

Push and hold [PTT] to display the SWR in a bar
graph readout.

o

When [PTT] is released, the frequency marker and
frequency indication move to the next frequency to
be measured.

!0

Repeat steps 

i

.and 

o

to measure SWR over the

entire frequency range.

!1

When the measured SWR is less than 1.5, the
antenna is well matched.

■

The IC-706MKIIG has a built-in circuit for measuring
antenna SWR while in SSB mode—no external equip-
ment or special adjustments are necessary.

☞

NOTE: The SWR of ANT1 only can be read since
ANT2 has no measuring circuit.

D

The best match is in this range.
