By default, rotating to left (when set to the 12 o'clock
position) adjusts the RF gain, and rotating to right
adjusts the squelch level as described below.

RF gain
Adjust the RF gain to decrease the noise received
from a nearby strong station.
• Rotate counterclockwise to reduce the RF gain, which
reduces the receive sensitivity. "RFG" appears when
is set to the counterclockwise from the 11 o'clock

position. "RFG" indicates that the RF gain is reduced.
L If a strong signal is received and "OVF" (Overflow)
appears, reduce the RF gain until "OVF" disappears.
SQL level
There are 2 types of SQL levels, depending on the
operating mode.
• Noise squelch
Rotate the

• S-meter squelch
The S-meter squelch mutes the audio output from the
speaker or headphones when the received signal is
weaker than the specified S-meter squelch level.

Adjusting the transmit output
power
Before transmitting, monitor your selected operating
frequency to make sure you do not cause interference to
other stations on the same frequency. It is good amateur
practice to listen first, and then, even if nothing is heard,
ask if the frequency in use once or twice, before you start
operating.
D Adjusting the transmit output power
1. Set the operating mode to SSB, CW, RTTY or FM.

• The Po meter level changes according
to your voice level in the SSB mode.
• The TX/RX indicator lights red and
is displayed.
L Tune the antenna before you view the power meter
level on the meter. If the antenna is not tuned properly,
the meter will not reflect the power level. (p. 11-2)
5. Touch "RF POWER."
6. Adjust the transmit output power to between 0 and
100%.
Po meter
• The Po meter displays the RF output power in a
percentage. It becomes the S-meter while receiving.
