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.

1Select an operating frequency.

2Press [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”.

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

•The current gain level appears on the sub- display.

4Press and hold Mic [PTT].

•The TX-RX LED lights red.

•Refer to “VOX” {page 30} for information on automatic TX/ RX switching.

5Speak 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.

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

•The TX-RX LED lights green or turns off, depending on the SQL control position.

7Press [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.

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.

1Press [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”.

2Press and hold [FM/AM (FM-N)]to toggle the selection between wide and narrow TX deviation.

•“” appears when narrow TX deviation is selected.

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.

1Select the operating frequency.

2Press [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}.

3Press [SEND].

• The TX-RX LED lights red.

4Operate the Keys or Paddle.
