Communicating with a Specific Remote Station

Using the Tone Squelch Function

The tone squelch opens the speaker audio only when a signal containing the specified

CTCSS tone is received. Using the digital code squelch (DCS) opens the speaker audio

only when a signal containing the specified DCS code is received. When the tone squelch

function is active, signals from other stations not containing the specified code are not

heard. The receiver will be quiet while waiting for a call from a specific station over a long

period of time.
