It is possible to show the SWR characteristics and antenna performance on a graph by measuring the SWR at
various points across an amateur band.
In order to measure the SWR of the antenna system
correctly, please turn off the antenna tuner before
measuring the SWR.
1. Please confirm that the RF output is over 10
Watts. In order to measure the SWR correctly,
10 Watts of RF output will be required. The TX
RF output may be adjusted using the RF PWR
knob.
2. Please confirm that the test transmission will not
cause QRM to other stations (be sure to ask if
the frequency is clear, and identify in accordance
with regulations). Then press the [ 6/14 ]( SWR CK )
key.
3. Perform the above procedure several times
across the band, and the SWR measured at the
various test frequencies will automatically be plot-
ted on the chart, creating a performance charac-
teristic graph for the current frequency range.

Advice: For the purposes of plotting the SWR across
the band, the resolution of the graph is every 10 kHz
on the 1.8 ~ 24 .9 MHz bands, and 100 kHz on the
28/50 MHz bands.
If a measurement is done on the same frequency as
where a previous measurement was made, the old
data will cleared and the new measurement data will
replace it.
Always observe proper operating courtesy to oth-
ers, and check to be sure the frequency is clear
before performing any SWR measurements.
