8 TRANSMIT FUNCTIONS

Speech Processor

In the SSB mode, TX output power varies according to the
loudness of the audio from the transmitting transceiver, which may
sometimes cause audibility to deteriorate at the receiving
transceiver. A speech processor can be used in this case to
compress signals via digital signal processing to raise the average
power.
Similarly, using the speed processor in the AM or FM mode
stabilizes the degree of modulation regardless of the loudness of
the audio from the transmitting transceiver and helps to enhance
intelligibility.

Turning ON/OFF Speech Processor

1 Press the mode key to select either SSB, AM or FM
mode.
2 Press F [PROC].
Pressing F [PROC] each time toggles the speech processor
between ON and OFF.
• When the speech processor is set to ON, "PROC
OUT:nnn" is displayed at the top of the screen. [nnn: 0 to
100]
The speech processor also functions with respect to
●
audio input from the ANI terminal of the ACC 2 connector
or the (USB-B) connector on the rear panel of this
transceiver.

Configuring the Speech Processor Input Level

1 Press and hold F [PROC] to display the Speech
Processor configuration screen

Switching the mode at the transmitting end to a non-
●
audio mode while the Speech Processor configuration
screen is displayed ends the Speech Processor
configuration screen.

2 Press F2 [
3 Press F4 [–]/ F5 [+] or turn the [MULTI/CH] control
to adjust the input level.
Setting Value
4 Press and hold F [PROC] or press [ESC] to end the
process.
The speech processor input level is used to adjust the
●
input level of the mixed audio between the audio source
input configured for microphone gain and that configured
on the audio source input screen.
Switching the mode at the transmitting end to a non-
●
audio mode while the Speech Processor configuration
screen is displayed ends the Speech Processor
configuration screen.

Configuring the Speech Processor Output Level

1 Press and hold F [PROC] to display the Speech
Processor configuration screen.
2 Press F2 [
Time
• "Output" is not displayed when the transmitting transceiver
is in the FM mode.
3 Press F4 [–]/ F5 [+] or turn the [MULTI/CH] control
to adjust the output level.
• The output level can also be adjusted by turning the [MIC/
PITCH)] control.
Setting Value
4 Press and hold F [PROC] or press [ESC] to end the
process.
Configuring the output to a level that is too high causes
●
distortion to occur in the TX signals and deterioration in
the radio wave quality as a result.
The speech processor output level is applied to both the
●
audio input from the microphone as well as the audio
source configured on the audio source input screen.
The speech processor output level is fixed and not
●
changeable in the FM mode.

Configuring the Speech Processor Effect

It is possible to configure how TX signals are to be processed by
the speech processor.
Press F6 [EFECT].
Pressing F6 [EFECT] each time switches the effect type.
Setting Value
Hard: Places priority on raising the average power although
signals may remain distorted.
Soft: Places priority on reducing the level of distortion with minimal
effect on raising the average power.
The speech processor effect selected is the same in
●
each mode.
