  • Page 55: Automatic Tone Frequency Id

    CONTINUOUS TONE CODED SQUELCH SYSTEM (CTCSS) CTCSS uses a subaudible tone to control the squelch of transceivers, and by this system you can reject signals from undesired stations. Suppose that only stations "A", "B", and "C" are programmed with the same tone frequency.

  • Page 56: Dual Tone Squelch System (dtss)

    DTSS provides a more refined method than CTCSS to selectively communicate with specific stations. The squelch on the transceiver opens only when the same 3-digit DTMF (Dual Tone Multi-Frequency) code is received that is programmed in this transceiver. You can select a 3-digit code from among 1000 combinations, 000 to 999.

  • Page 57

    USING DTSS 1 Select the desired band. 2 Press [F], [DTSS] to switch the DTSS function ON. • "DT" appears. 3 Select the appropriate DTSS code {page 50}. 4 When you are called: The squelch of your transceiver opens only when the stored DTSS code is received.

  • Page 58: Dtss And Repeaters

    DTSS and Repeaters Pressing Mic [PTT] transmits the DTSS signal after a short delay. When using repeaters with long response times, this delay helps the repeater avoid losing a portion of the DTSS code. The delay time is 350 ms during simplex operation.

  • Page 59

    Page also uses DTMF codes to address specific stations. When your transceiver transmits a DTMF code, the squelch of only the transceivers that have the same code programmed, opens. Unlike DTSS, Page allows you to choose whether you will call a single station or a group of stations. In addition, Page offers the added benefit of identifying who called you.

  • Page 60
