5 BASIC COMMUNICATIONS

AM TRANSMISSION

Each mode used on the HF Amateur bands has its

own advantages. Although long distance DX contacts

may be less common while using AM, the superior

audio quality characteristic of AM operation is one

reason why some hams prefer this mode.

If necessary, refer to “OPERATING BASICS”,

beginning on page 10, for details on how to receive.

1 Select an operating frequency.

2 Press [FM/AM (FM-N)] until “AM” appears.

• If “AM” does not appear, select “FM” first, then

press [FM/AM (FM-N)]. The mode indicator

changes to “AM”.

3 Press [MIC (CAR)] to enter the Microphone gain

adjustment mode.

• The current gain level appears on the sub-

display.

4 Press and hold Mic [PTT].

• The TX-RX LED lights red.

• Refer to “VOX” {page 30} for information on

automatic TX/ RX switching.

5 Speak into the microphone and adjust the

MULTI/CH control so that the power meter slightly

reflects your voice level.

• Speak in your normal tone and level of voice.

Speaking too close to the microphone or too

loudly may increase distortion and reduce

intelligibility at the receiving end.

• You may want to use the Speech Processor.

Refer to “SPEECH PROCESSOR” {page 31}

for details.

6 Release Mic [PTT] to return to Reception mode.

• The TX-RX LED lights green or turns off,

depending on the SQL control position.

7 Press [MIC (CAR)] or [CLR] to exit the Microphone

gain adjustment mode.

Refer to “COMMUNICATING AIDS”, beginning on

page 28, for information on additional useful operation

functions.

Note: When the TX power meter reading exceeds the value that

you specified in the TX Power setting {page 56}, decrease the

microphone gain or adjust your tone and level of voice.

NARROW BANDWIDTH FOR FM

Select wide band or narrow band TX deviation

depending on whether the other station is using wide

band or narrow band filter for FM mode. While “NAR”

appears, the TS-590S transceiver transmits signals in

narrow band FM but the reception IF filter bandwidth

remains unchanged (Wide). The deviation selection

is crucial to avoid audio distortion or insufficient

intelligibility that the other station will encounter.

1 Press [FM/AM (FM-N)] until “FM” appears.

•

If “FM” does not appear, select “AM” first, then

press [FM/AM (FM-N)].

The mode indicator

changes to “FM”.

2 Press and hold [FM/AM (FM-N)] to toggle the

selection between wide and narrow TX deviation.

• “

” appears when narrow TX deviation is

selected.

CW TRANSMISSION

CW operators know that this mode is very reliable

when communicating under worst conditions. It may

be true that newer digital modes rival CW as being

equally as useful in poor conditions. These modes,

however, do not have the long history of service nor

the simplicity that CW provides.

This transceiver has a built-in electronic keyer that

supports a variety of functions. For details on using

these functions, refer to “ELECTRONIC KEYER”

{page 33}.

If necessary, refer to “OPERATING BASICS”,

beginning on page 10, for details on how to receive.

1 Select the operating frequency.

2 Press [CW/FSK (REV)] until “CW” appears.

• If “CW” does not appear, select “FSK” first, then

press [CW/FSK (REV)]. The mode indicator

changes to “CW”.

• To precisely tune in another station, use Auto

Zero-beat. Refer to “AUTO ZERO-BEAT”

{page 23}.

3 Press [SEND].

• The TX-RX LED lights red.

4 Operate the Keys or Paddle.

• As you transmit, you should hear a sidetone

that lets you monitor your own transmission.

5 Press [SEND] to return to Reception mode.

• The TX-RX LED lights green or turns off,

depending on the SQL control setting.
