6 ANALOG COMMUNICATIONS / 6.4 Adjusting the Reception Sensitivity of the Repeater (Squelch Level)103FUNC (E)/ Ver 2.00Note When the repeater is operated in the repeater mode, even if Squelch Off is enabled, the repeater does not transmitusing the Repeat PTT control unless the received signaling (the QT tone or DQT code) matches the signalingpreconfigured for the repeater (the QT tone or DQT code).6.4 Adjusting the Reception Sensitivity of the Repeater (Squelch Level)Squelch Level is the threshold receive level by which the repeater can determine that the received signal has acarrier.If the repeater is not receiving any signals, noise is automatically eliminated. Only when the repeater receives thesignal having the higher level than the configured signal level, the squelch opens and the received audio becomesaudible.The level of the received signal which unmutes the speaker can be adjusted by changing the value in Squelch Leveldepending on how the repeater is used; for instance, when an excessively interfering signal is present.If the repeater receives a signal, the speaker is usually unmuted and emits the received audio at the point adjusted bySquelch Open; however, if the maximum value of 9 is configured in Squelch Level, the speaker is unmuted at thepoint adjusted by Squelch Tight. If a value of 0 is configured in Squelch Level, the repeater is always placed inreceive mode.If no signaling used for reception (the QT tone or DQT code) is configured, the speaker is unmuted on a channel with“Analog” or “Mixed” configured in Channel Type.(Refer to Configuring the Reception Method of a Channel (Channel Type).)The squelch function can be enabled by the Squelch Off operation even on an NXDN channel. Although RX1 LEDlights on an NXDN channel, mute is not forcibly unmuted. The RAN is reset and the repeater is in the standby state forthe establishment of frame synchronization.Note・ Squelch Level cannot be configured on a DMR channel and NXDN channel. On a DMR channel and NXDNchannel, the repeater behaves with Squelch Level 1 fixed.・ The repeater does not perform the repeat behavior if no signal where QT/ DQT/ RAN/ Color Code matches isreceived even if Squelch Off is configured.・ On a channel with “NXDN” or “Mixed” configured in Channel Type, RX2 LED does not light green unless a signalwhere the RAN matches is received even if an NXDN signal is received while Squelch Off is configured.Configuration using KPG-D7・ Configuring Squelch Level ( Edit > Optional Features > Common Page 1 > Squelch Level)
