4 RECEIVE AND TRANSMIT ■ Functions for receive D Squelch function The squelch function detects signals with voice components and squelches (mutes) unwanted signals, such as unmodulated beat signals. This provides quiet standby. When you need to receive weak signals, the squelch should be turned OFF. D Noise blanker The noise blanker function reduces pulse type noise, such as that coming from engine ignitions. The noise blanker may distort reception of strong signals. In such cases, the noise blanker should be turned OFF. D AGC OFF function The receiver gain is automatically adjusted according to the received signal strength with the AGC (Automatic Gain Control) function, to prevent distortion from strong signals and to obtain a constant output level. When receiving weak signals with adjacent strong signals or noise, the AGC function may reduce the sensitivity. In this situation, the AGC function should be deactivated. D Clarity control Voice signals received from other stations may be difficult to receive. This may sometimes happen if a station is transmitting slightly off frequency. In such cases, vary the receive frequency only, using the [CLARITY] control. Push [SQL] to toggle the function ON or OFF. DUP SQL • "SQL" appears when the squelch function is turned ON. Push [NB] to toggle the function ON or OFF. RX DUP NB • "NB" appears when the noise blanker function is turned ON. Push [AGC] to toggle the function ON or OFF. RX DUP AGC • "ê" appears when the AGC function is deactivated. Adjust [CLARITY] to improve the audio signal. [CLARITY] 9
