The IC-7200 has a built-in circuit for measuring an-
tenna SWR—no external equipment is necessary.

METER
for 1 sec. several times to
select the SWR meter.
r
Push
[PTT]
to transmit; then read the actual SWR
from the meter.
•
≤
1.5 well-matched antenna
•
>
1.5 may indicate an antenna out of its well-matched
frequency range. If much larger than 2.0, check an-
tenna and cable connections, etc.
