The IC-7000 has a built-in circuit for measuring an-
tenna SWR—no external equipment or special adjust-
ments are necessary.
The IC-7000 can measure SWR in 2 ways—spot mea-
surement and plot measurement.
q
Select CW or RTTY operation with
[MODE]
.
w
Confirm that the output power is over 30 W.
e
Select the menu
S-1
.
r

one or more times to select the
SWR meter.
t
Key down or push
[PTT]

q
Confirm that the output power is over 30 W.
w
Set the center frequency for the SWR to be mea-
sured.

Push and hold
[F-4

for 1 sec. one or more
times to select the desired measuring step from 10,
50, 100 and 500 kHz.
t
Push
[F-2]
or
[F-3]
one or more times to select the
desired number of measuring steps from 3, 5, 7, 9,
11, and 13 steps.
y
Push
[F-1]
to start the measuring.
u
Push and hold
[PTT]
on the microphone to mea-
sure the SWR.
• Frequency marker, “

When releasing
[PTT]
, the frequency marker and
frequency indication move to the next frequency to
be measured.
o
Repeat steps
u
and
i
to measure SWR over the
entire frequency range.

When the measured SWR is less than 1.5:1, the
antenna is well matched with the transceiver in the
measured frequency range.
Push [F-1] to start
mesuring.
Push [F-2] or [F-3] to select number of
SWR mesuring steps.
Frequency marker appears and moves
after measurement.
Push [F-4] to Select
SWR mesuring steps.
