Measuring SWR
The transceiver has an SWR meter. There are 2 ways
to measure SWR. One way is a spot measurement,
and the other is a plot measurement.
D Spot measurement
1. Turn OFF any antenna tuner.
L Perform this step if you want to measure the SWR of
the antenna itself.
2. Set the desired frequency band and a frequency
in the portion of the band that you use the most.
3. Select the antenna connector to which the
antenna you want to measure is connected.
4. Select the RTTY mode.
5. Set the RF power to 30 W or more in the Multi-
function menu.
6. Touch the meter, and then touch [SWR] to display
the SWR meter.
SWR meter
NOTE: Before transmitting, monitor the operating
frequency to make sure you will not cause
interference to other stations on the same frequency.
7. Hold down [PTT] to transmit, and then read the
SWR on the meter.
The best match is within this range. (1.5 or less)
L If the SWR meter indicates 1.5 or less, the antenna is
matched.
L If the SWR is a high value, adjust your antenna.
8. Release [PTT] to stop transmitting.
