WebDownlink Tone. Tones are often attached to a repeater's uplink frequency to control access or limit noise/interference. In commercial radio applications and invented by Motorola, the term is known as PL, which was short for Motorola Private Line. In the amateur radio community, the non-propriety term of Continuous Tone-Coded Squelch System, or ... Tone squelch, or another form of selective calling, is sometimes used to solve interference problems. Where more than one user is on the same channel (co-channel users), selective calling addresses a subset of all receivers. Instead of turning on the receiver audio for any signal, the audio turns on only in the presence of the correct selective calling code. This is akin to the use of a lock on a door. A carrier squelch is unlocked and will let any signal in. Selective calling locks o…
