What is squelching? The purpose of squelch is to mute the audio output of your receiver when the signal from the transmitter is turned off or is too weak to be received. Without squelch you would hear radio noise in your earphone. The squelch function is preset and cannot be changed on the LR-300.
What is the function of SQ? To reduce noise of our systems, Listen now offers a noise reduction technology called ListenSQ.
