Kenwood TS-570S, TS-570D Selecting a Mode, Adjusting Squelch, Selecting a Frequency

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.
3			LSB
			USB
			CW
4		FSK
		FM
			AM
5	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.

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.

Scale	Display	Functional State
S	Received signal strength	Receive
PWR	Transmit output power	Transmit
ALC	Automatic level control	Transmit
	status
SWR	Antenna system standing	Transmit
	wave ratio
COMP	Speech compression level	Transmit plus
	when using the Speech	SSB/AM/FM mode
	Processor {page 32}	plus [PROC] ON

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.
