SPEECH PROCESSOR

XIT (TRANSMIT INCREMENTAL TUNING)

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.

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.

1Press [XIT].

• “XIT” and the XIT offset appear.

3Turn the RIT/XIT control to change your transmit frequency.

1Select SSB, FM, or AM mode.

2Press [PROC] to switch the Speech Processor ON.

“PROC” appears. The SWR meter disappears, and the COMP meter appears.

3Access 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 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.

4To switch the Speech Processor OFF, press [PROC] again.

“PROC” disappears. The COMP meter disappears, and the SWR meter appears.

4To 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.
