4 OPERATING BASICS

1

SELECTING A MODE

Depending on which operating mode you want to select,

 

 

press the [LSB/USB], [CW/FSK], or [FM/AM] button.

 

2

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

 

6

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.

7

ADJUSTING SQUELCH

 

 

The purpose of squelch is to silence audio output from

8

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

 

9

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

 

10

operators prefer leaving the squelch control fully

counterclockwise unless operating full-carrier modes

 

such as FM or AM.

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.

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.
