Applications



  • On-Site Communication: Provides clear, reliable communication for settings such as golf courses, warehouses, office buildings, factories, colleges, and universities.

  • Community Repeater: Each channel provides for quick and reliable decodes for up to 64 users with 50 CTCSS and 112 DCS codes available.

  • Trunking Systems: Excellent choice for interfacing LTR and Passport trunking controllers.

  • External Peripherals: Easily connects to your favorite telephone interconnects, DC remotes, external tone panels, and various signaling products.

  • Amateur Repeater: Both the VHF and UHF versions operate in their respective amateur region of the spectrum.

  • Link-Radio Ready: Connect a "Link- Radio" to the repeater for cross-band applications and interoperability.

  • GMRS Ready: Add a tuned internal duplexer and everything is set to put a GMRS repeater on the air.

  • Feature-Rich Base Station: 16 full-duplex channels that can support up to 64 users per channel.

  • Customizable: The CS-540 uses Flash Memory, which permits updates
