It is possible to read the measured SWR value by placing the marker onto the desired frequency (measure-
ment test point) of the SWR graph.
1. Press the [ 2/3.5
](
MARKER
) key to turn the marker
function on; the marker cursor will be displayed.
2. Use the [ 3/5
](
W
) and [
4/7
](
X
) keys to move the
marker line and select the desired frequency for
which you want to read the previously-measured
SWR.
Advice : Please use an antenna with the SWR be-
low 1.5:1. If the SWR is over 1.5:1, the final protec-
tion circuit activates, and the RF output power may
be reduced.
If the SWR is over 3.0 in the amateur band, there is
a possibility that the coaxial cable or the antenna
itself (antenna system) may have some problem.
Please take the necessary corrective action so as to
ensure optimum, safe performance in your station.
The antenna tuner in the radio can match the SWR
between the transceiver and the antenna; however,
keep in mind that this is not affecting the SWR at the
antenna feedpoint itself. In cases of higher-than-
desirable SWR, we recommend corrective action be
taken at the antenna itself.
When you want to clear the measured SWR value at
the marker test point, press the [
2/3.5
](
MARKER
)
key.
