4 OPERATING BASICS
SELECTING A FREQUENCY
There are two simple methods to select a frequency.
AManual Tuning
Turn the Tuning control or press Mic [UP]/[DWN] to
select the exact frequency.
BDirect Frequency Entry (Keypad)
Press [ENT], then directly enter the desired
frequency using the numeric keypad. For details,
refer to “Direct Frequency Entry” {page 29}.
FRONT PANEL METER
The multifunction meter measures the parameters in the
table below. The appropriate meters automatically
become functional according to which state the
transceiver is in. Peak readings for the S-meter, ALC,
SWR, COMP, and PWR functions are held for a brief
moment.

Note:
◆
The COMP meter functions only when the Speech Processor is
ON while using SSB, FM, or AM mode. When the COMP meter
appears, the SWR meter disappears.
◆
Peak Hold readings cannot be deactivated on this transceiver.
SELECTING A MODE
Depending on which operating mode you want to select,
press the [LSB/USB], [CW/FSK], or [FM/AM] button.
The second function on each button is accessed by
again pressing the same button. For example,
repeatedly pressing [LSB/USB] toggles between LSB
and USB modes.
In SSB mode, the transceiver automatically selects LSB
for frequencies lower than 9.5 MHz, and selects USB for
9.5 MHz or higher frequencies if the Tuning control, the
MULTI/CH control, or Mic [UP]/[DWN] is used to cross
the frequency of 9.5 MHz. This is also true if using the
front panel [UP] or [DOWN] button when the 1 MHz
Step mode is used.
ADJUSTING SQUELCH
The purpose of squelch is to silence audio output from
the speaker when no signal is present. When squelch
is set correctly, you will hear sound only while a station
is actually being received. The point at which ambient
noise on a frequency just disappears, called the squelch
threshold, depends on the frequency.
Turn the SQL control clockwise to just eliminate the
background noise when no signal is present. Many
operators prefer leaving the squelch control fully
counterclockwise unless operating full-carrier modes
such as FM or AM.
