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