Speech Processor; Xit (Transmit Incremental Tuning) - Kenwood TS-570D, TS-570S Instruction Manual

8 COMMUNICATING AIDS

SPEECH PROCESSOR

1
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
2
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.

3 Access Menu No. 15 and select the desired level of
compression.

• Selectable range is 0 dB to 25 dB in steps of 5
dB. The recommended selection and default is
10 dB.
• Using higher compression will not improve your
12
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
13
compression.
4 To switch the Speech Processor OFF, press [PROC]
again.

disappears, and the SWR meter appears.

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].
• "XIT" and the XIT offset appear.
Time
2 If required, press [CLEAR] to reset the XIT offset
to 0.
3 Turn the RIT/XIT control to change your transmit
frequency.
Time
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.
