Ctcss Operation - Vertex Standard VX-110 Operating Manual

Advanced Operation
Many repeater systems require that a very-low-frequency audio tone be superimposed on
your FM carrier in order to activate the repeater. This helps prevent false activation of the
repeater by radar or spurious signals from other transmitters. This tone system, called
"CTCSS" (Continuous Tone Coded Squelch System), is included in your VX-110, and is
very easy to activate.
CTCSS setup involves two actions: setting the Tone Frequency and then setting of the
Tone Mode. These actions are set up by using Menu Items #23 and #24.
