7 OPERATING AIDS
SPEECH PROCESSOR (SSB/AM)
The speech processor functions by leveling the large fluctuations in your voice when you speak. This leveling action effectively raises the average transmit output power resulting in a more understandable signal when operating using SSB or AM. You will notice that using the speech processor makes it easier to be heard by distant stations.
1Select SSB or AM mode.
2Select the preferred processor characteristics via Menu No. 25 (PROC.LOW) and Menu No. 26 (PROC.HI).
•You can customize the low and high ranges of the speech envelope from

4Press [METER] to select the COMP function.
5While speaking at your normal voice level, adjust the PROC control for a level of 10 dB or less.
•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.

6Press [METER] to select the ALC function.
7The compression level affects the ALC setting for SSB; therefore, while continuing to speak into the microphone, adjust the CAR control for a reading within the ALC zone.
•Keep the meter inside the ALC zone for the cleanest transmit signal and to avoid interfering with other stations on adjacent frequencies.
8Press [METER] to select the COMP function to allow you to monitor the compression while transmitting.
9To switch OFF the processor, press [PROC] again.
•“PROC” goes out.
Note: Input audio that is controlled by the AGC will be clipped. Therefore, when mixing audio with the operator’s voice, lower the MIC gain control as necessary.
CHANGING FREQUENCY WHILE TRANSMITTING
Moving your frequency while transmitting is usually an unwise practice due to the risk of interference to other stations. While transmitting, if you select a frequency outside the transmit frequency range, the transceiver is automatically forced to receive mode. If transmit was selected using the [SEND] key, transmission will not be resumed until you select a frequency inside the transmit frequency range, and you transmit again.
TRANSMIT MONITOR
The Transmit Monitor function allows you to hear your own transmitted signal.
