PL is encoding a tone or tone squelch or CTS or CTCSS on some radios. Check your instruction manual for info on Tones or PLs and it may clear up some confusion. When a PL is used on a repeater or on simplex to close its/your squelch, a transmitter must transmit to you the correct tone to open your squelch to allow you to listen to that transmission. Same for you to open another hams/repeater's squelch control if they have their receiver set for Tone Squelch mode. You need to transmit a tone to open their receiver.
