COMMUNICATING AIDS
XIT (TRANSMIT INCREMENTAL TUNING)
Similar to RIT, XIT provides the ability to change your
transmit frequency by
9.99 kHz in steps of 10 Hz
without changing your receive frequency.
If the Fine
Tuning (
[FINE]
) function is ON, the step size is 1 Hz.
1
Press
[XIT]
.
°
±XIT² and the XIT offset appear.
2
If required, press
[CLEAR]
to reset the XIT offset
to
0.
3
Turn the
RIT/XIT
control to change your transmit
frequency.
4
To cancel XIT, press
[XIT]
.
°
The transmit frequency is returned to the
frequency that was selected prior to step 1.
Note:
The frequency shift set by the
RIT/XIT
control is also used by
the RIT function.
Therefore, changing or clearing the XIT offset also
affects the RIT offset.
SPEECH PROCESSOR
The Speech Processor levels large fluctuations in your
voice while you speak.
When using SSB, FM, or AM
mode, this leveling action effectively raises the average
transmit output 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.

[PROC]
to switch the Speech Processor ON.

Selectable range is 0 dB to 25 dB in steps of 5
dB.
The recommended selection and default is
