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.

1Select USB, LSB, FM, or AM mode.

2Press [PROC/ 9] to turn the Speech Processor ON.

¥ÒPROCÓ appears.

3Press [PROC/ 9] (1 s) to enter the Speech Processor input level adjustment mode.

4As 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.

5Press [PROC/ 9] (1 s) to exit the Speech Processor input level adjustment mode.

6Press [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.

1Press [XIT].

¥ÒXITÓ and the XIT offset appear.

2If required, press [CL] to reset the XIT offset to 0.

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

4To turn XIT OFF, press [XIT].

¥ÒXITÓ 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.
