114RECEIVE AND TRANSMIT Functions for receiveDD Squelch functionThe squelch function detects signals with voice com-ponents and squelches (mutes) unwanted signalssuch as unmodulated beat signals. This providesquiet stand-by.When you need to receive weak signals, the squelchshould be turned OFF.➥ Push [F] then [2 SQL ] to switch the function ONand OFF.• “SQL” appears when the squelch function is turned ON.[2 SQL ][F]DD Noise blankerThe noise blanker function reduces pulse type noisesuch as that coming from engine ignitions, etc.The noise blanker may distort reception of strong sig-nals. In such cases, the noise blanker should beturned OFF.➥ Push [F] then [1 NB] to switch the function ON andOFF.• “NB” appears when the squelch function is turned ON.[1 NB ][F]DD AGC OFF functionThe receive gain is automatically adjusted accordingto received signal strength with the AGC (AutomaticGain Control) function to prevent distortion fromstrong signals and to obtain a constant output level.When receiving weak signals with adjacent strongsignals or noise, the AGC function may reduce thesensitivity. In this situation, the AGC function shouldbe deactivated.➥ Push [F] then [5 AGC ] to switch the function ONand OFF. • “ ” appears when the squelch function is turned OFF.A G C[5 AGC ][F]DD RF gain settingThe receiver gain can be reduced with the RF gainsetting. This may help to remove undesired weak sig-nals while monitoring strong signals.Usually, the AGC function reduces the RF gain ac-cording to the receive signal strength and these weaksignals are removed. However, during no signal re-ception, these weak signals may not be heard.In such cases, the RF gain may be useful for setting aminimum level at which to hear signals.q Push [F] then [6 RF - G ] to select the RF gain setmode, as shown at right.w Rotate [CH] selector to set the desired minimumcutting level.• “0” to “9” are available.• S-meter shows the minimum permitted level.e Push [SET] to exit the RF gain set mode. |
