Noise is heard. Noise disappears.
When the Squelch control is adjusted correctly, you
will hear sound only when the other station is
transmitting.
The point at which ambient noise just disappears (the
threshold) depends on the modulation mode and
frequency.
When receiving a weak signal, turn the control fully
counterclockwise.
Note:
If the Squelch control is turned fully clockwise, you
may
mistakenly think that receiver sensitivity is low or the transceiver is
fadmg
to
output sound. Normally, the Squelch control should be
set at the fully counterclockwise position unless in the FM or AM
mode.

RIT control
The Receiver Incremental Tuning control has two
functions:
• Receiver frequency shift
• Scan speed change
(1) Receiver frequency shift
With the RIT on, the receiver frequency is
adjustable without affecting the transmitter
frequency. Turn the RIT control clockwise, and the
frequency will shift up.
For details, refer to "RIT Operation" on page 41.
(2) Scan speed change
Using the RIT control. the scan speed can be
changed during memory or program scan. Turn
the RIT control counterclockwise, and the scan
speed will increase. When exiting scan, center the
RIT control.
For details, refer to page 40.
Note: Remember that the RIT control affects both the receiver
frequency shift, and scan speed. If you switch the RIT on after
using the scan, the receiver frequency may be shifted.
@ IF SHIFT control
Allows shifting of an interfering signal outside the filter
pass band to reduce or eliminate the adjacent signal
interference.
Normally, set the control to the center (detent)
position.
For details, refer to "IF Shift'· on page 43.
Note:
The IF SHIFT control functions
In
the SSB and CW
modes, and does not function in the AM and FM modes.
