3 OPERATING BASICS ADJUSTING THE SQUELCH The purpose of the Squelch is to mute the speaker when no signals are present. With the squelch level correctly set, you will hear sound only while actually receiving signals. The higher the selected squelch level, the stronger the signals must be to receive. The appropriate squelch level depends on the ambient RF noise conditions. Turn the SQL control when there are no signals present to select the squelch level at which the background noise is just eliminated; the green TX-RX LED will turn off. Many ham operators prefer leaving the SQL control fully counterclockwise unless operating on a full-carrier mode such as FM. The squelch level for the transceiver is preset at the factory to approximately the 9 o'clock position for FM and 11 o'clock for SSB and AM. MULTI-FUNCTION METER The multi-function meter measures the parameters in the table below. The S-meter and FILTER scales appears when the transceiver is in receive mode, and the PWR meter appears when it is in transmit mode. Each press of [METER (DRV)] cycles between the ALC, COMP, and SWR meters. Peak readings for the S-meter, ALC, SWR, COMP, and PWR functions are held momentarily. ALC TUNING A FREQUENCY Turn the Tuning control clockwise or press Mic [UP to increase the frequency. Turn the Tuning control counterclockwise or press Mic [DWN] to decrease the frequency.

MULTI-FUNCTION METER
The multi-function meter measures the parameters
in the table below.
The S-meter and FILTER scales
appears when the transceiver is in receive mode, and
the PWR meter appears when it is in transmit mode.
Each press of
[METER (DRV)]
cycles between the
ALC, COMP, and SWR meters.
Peak readings for the
S-meter, ALC, SWR, COMP, and PWR functions are
held momentarily.
ALC
COMP
SWR
Meter Name
Parameters Measured
S
Strength of received signals
PWR
Transmission output power
ALC
Automatic level control status
SWR
Antenna system standing wave ratio
COMP
Speech compression level when
using the Speech Processor
{page 31}
FILTER
IF filter width {page 38}
Note:
◆
The COMP meter functions only when the Speech
Processor is ON for SSB, FM, or AM mode.
◆
Peak Hold readings cannot be deactivated.
◆
The S-meter responds differently in FM mode, compared to
other modes.
This is not a malfunction.
ADJUSTING THE SQUELCH
The purpose of the Squelch is to mute the speaker
when no signals are present.
With the squelch level
correctly set, you will hear sound only while actually
receiving signals.
The higher the selected squelch
level, the stronger the signals must be to receive.
The
appropriate squelch level depends on the ambient RF
noise conditions.
Turn the
SQL
control when there are no signals
present to select the squelch level at which the
background noise is just eliminated; the green TX-RX
LED will turn off.
Many ham operators prefer leaving
the
SQL
control fully counterclockwise unless
operating on a full-carrier mode such as FM.
The
squelch level for the transceiver is preset at the
factory to approximately the 9 o’clock position for FM
and 11 o’clock for SSB and AM.
TUNING A FREQUENCY
Turn the
Tuning
control clockwise or press Mic
[UP
to increase the frequency.
Turn the
Tuning
control
counterclockwise or press Mic
[DWN]
to decrease the
frequency.
You may prefer directly entering a frequency using
the numeric keypad if the desired frequency is far
from the current frequency.
Press
[ENT]
, then press
the numeric keys as necessary.

“Direct Frequency Entry” {page 28}.
