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.

times to select the desired measuring step from 10,
50, 100 and 500 kHz.
tPush [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.
yPush [F-1] to start the measuring.
uPush and hold [PTT] on the microphone to mea-
sure the SWR.
•Frequency marker, “∫,” appears below SWR graph.
•RTTY mode is automatically selected.
iWhen releasing [PTT], the frequency marker and
frequency indication move to the next frequency to
be measured.
oRepeat steps u and i to measure SWR over the
entire frequency range.
!0When 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.
