RF gain and SQL level
Rotate
AF
RF/SQL
(outer) to adjust the RF gain and
SQL level.
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” 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 level, depending on the
operating mode.
•
Noise squelch
Rotate the
AF
RF/SQL
(outer) until the noise just
disappears and the TX/RX indicator goes OFF.
•
S-meter squelch
The S-meter squelch disables the audio output from
the speaker or headphones when the received signal is
weaker than the specified S-meter squelch level.
Rotate the
AF
RF/SQL
clockwise from the 12 o’clock
position to adjust the S-meter threshold level.
L
You can change the
AF
RF/SQL
(outer) control type in

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.
