Volume

12

Beep output level

You can adjust this to suit your

adjustment

 

 

preference.

13

Sidetone volume

For full break-in, it is easier to hear the

 

 

 

 

sidetone if you raise this volume.

 

14

VGS-1 message playback

You can check what has been

 

 

volume

recorded.

 

 

 

 

 

 

 

 

15

VGS-1 announcement

Switch this OFF if you do not need

 

 

volume

announcements while working the

 

 

radio.

 

 

 

 

16

VGS-1 announcement

You can adjust this to suit your

 

 

speed

preference.

 

 

 

 

 

 

 

RX IF filters

17

Use CW IF filter for SSB

This is useful for PSK31 operations.

 

 

reception

 

 

 

 

 

DSP

18

DSP RX equalizer

You can adjust frequency

equalizers

 

 

characteristics during reception. Select

 

 

the position that best suits your

 

 

 

 

 

 

external speaker/headphones.

 

19

DSP TX equalizer

As with #18, this is not as versatile as a

 

 

 

dedicated graphic equalizer, but it is

 

 

 

useful for tailoring TX frequency

 

 

 

characteristics to match your mic and

 

 

 

voice.

DSP TX

20

DSP TX filter bandwidth

As this is AF DSP, it is not as versatile

filters

 

 

as IF DSP, but it can be used to

 

 

remove low frequencies during

 

 

 

 

 

 

transmit.

 

 

 

 

Fine-tuning

21

TX power output control

You can choose between a 5W step

TX output

 

 

and a 1W step. Useful for fine

 

 

adjustment of output when using a

 

 

 

 

 

 

linear amp.

TX control

22

Time-out timer

This automatically terminates

 

 

 

transmission after a set time. Useful as

 

 

 

a failsafe for network (KNS)

 

 

 

operations.

Transverter

23

Frequency when using

You can change the frequency

 

 

transverter

displayed by the transceiver to the

 

 

operating frequency of the Transverter.

 

 

 

 

 

 

Unlike the TS-570, you can set any

 

 

 

frequency.

 

24

Output power adjustment for

Transverter output is fixed at 5W for

 

 

transverter

the TS-570, but with the TS-480 you

 

 

can choose output freely (within the

 

 

 

 

 

 

transmitter’s capability).
