Adjusting the SQL control
Adjustment of the SQL control applies to all modes of
reception.
What the SQL control does
The SQL (squelch) control adjusts the threshold of the
signal intensity that opens the squelch.
When the receiver receives a signal above the threshold,
the squelch will open,
M
will appear in the display,
and you will hear the transmission sound.
When the squelch opens during scanning, the receiver
stops scanning. This is called a “scanning pause”.
As you turn the SQL control counterclockwise to MIN, the
receiver will pause scanning on weaker signals. But this
may cause the receiver to pause scanning on unwanted
noise signals.
As you turn the SQL control clockwise to MAX, the
receiver will cut off the weaker signals and receive only
stronger signals. If it is turned too far clockwise, on the
other hand, there may be no signal strong enough to cause
a scanning pause.
Adjusting the
SQL
control
Start from the MIN position and turn it
clockwise towards MAX to the point the
B
indication disappears in the display.

When there is a signal above the squelch threshold,
m
will light up and the receiver pauses scanning. Scanning
will resume automatically when the signal breaks off.
