6 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.

When looking for others operating on AM, check the

following frequencies first:

3885 kHz, 7290 kHz, 14286 kHz, 21390 kHz, and

29000 ~ 29200 kHz

If necessary, refer to “OPERATING BASICS”,

beginning on page 18, for details on how to receive.

1 Select an operating frequency.

2 Press [MODE] until “AM” appears.

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

press [MODE] (1 s). The mode indicator

changes to “AM”.

3 Press [MIC/ 5/ RF.G] to enter the Microphone gain

adjutment mode.

• The current gain level appears on the sub-

display.

4 Press and hold Mic [PTT].

• The LED lights red.

• Refer to VOX function for information on

automatic TX/ RX switching {page 36}.

5 Speak into the microphone and adjust the

MULTI 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 37}

for details.

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

• The LED lights green or turns off, depending

on the SQL control position.

7 Press [MIC/ 5/ RF.G] to exit the Microphone gain

adjustment mode.

Refer to “COMMUNICATING AIDS”, beginning on

page 34, for information on additional useful

operation functions.

Note:

When the TX power meter reading exceeds the value that you

specified in TX Power setting {page 65}, 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-480 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 [MODE] until “FM” appears.

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

press [MODE] (1 s). The mode indicator

changes to “FM”.

2 Press [FIL/ NAR] (1 s) to toggle the selection

between wide and narrow TX deviation.

• “NAR” appears when the narrow TX deviation

is selected.

NARROW BANDWIDTH FOR AM

When receiving AM, you can further decrease the

bandwidth to eliminate interference. However, the

transmission deviation of AM is not affected by this

selection.

1 Press [MODE] until “AM” appears.

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

press [MODE] (1 s). The mode indicator

changes to “AM”.

2 Press [FIL/ NAR] (1 s) to toggle the selection

between Normal and Narrow.

• “NAR” appears when the narrow bandwidth is

selected for the AM reception.
