COMMUNICATING AIDS
SPEECH PROCESSOR
The Speech Processor levels out large fluctuations in
your voice while you speak.
When using SSB, FM, or
AM mode, this leveling action effectively raises the
average TX power, resulting in a more
understandable signal.
The amount of voice
compression is fully adjustable.
You will notice that
using the Speech Processor makes it easier to be
heard by distant stations.
1
Select USB, LSB, FM, or AM mode.
2
Press
[PROC/ 9]
to turn the Speech Processor
ON.
•
“PROC” appears.
3
Press
[PROC/ 9] (1 s)
to enter the Speech
Processor input level adjustment mode.
4
As you speak into the microphone, turn the
MULTI
control so that the compression meter
indicates that the compression level is around
10 dB while you speak.
•
Using higher compression will not improve your
signal clarity or apparent signal strength.
Excessively compressed signals are more
difficult to understand due to distortion and are
less pleasant to hear than signals with less
compression.
5
Press
[PROC/ 9] (1 s)
to exit the Speech
Processor input level adjustment mode.
6
Press
[MIC/ 5/ RF.G]
to enter the Speech
Processor output level adjustment mode.
•
As you speak into the microphone, turn the
MULTI
control so that the ALC meter reflects
according to your voice level but does not
exceed the ALC limit.
Press
[MIC/ 5/ RF.G]
to
exit when you finish the adjustment mode.
XIT (TRANSMIT INCREMENTAL TUNING)
Similar to RIT, XIT provides the ability to change your
transmission frequency by
±
9.99 kHz in steps of 10 Hz
without changing your reception frequency.
If the Fine
Tuning function is ON, the frequency step size
becomes 1 Hz.
1
Press
[XIT]
.
•
“XIT” and the XIT offset appear.
2
If required, press
[CL]
to reset the XIT offset to
0.
3
Turn the
RIT/ XIT
control to change your transmit
frequency.
4
To turn XIT OFF, press
[XIT]
.
•
“XIT” and offset frequency display disappear.
The transmission frequency is returned to the
frequency that was selected prior to step
1
.
Note:
◆
If the Fine Tuning function is ON, you can adjust the frequency
within
±
9.99 kHz.
◆
The frequency shift set by the
XIT
control is also used by the RIT
function.
Therefore, changing or clearing the XIT offset also
affects the RIT offset.
◆
When the XIT frequency exceeds the limit of available
transmission frequency, the transceiver automatically stops
transmitting.
