    Specifications FREQUENCY RANGE The COBRA 25 LTD ST transceiver represents one of the most advanced AM two- way radios ever designed for use as a Class D station in the Citizens Radio Service.

    Installation Location Plan the location of the transceiver and microphone bracket before starting the installation. Select a location that is convenient for operation and does not inter- fere with the driver or passengers in the vehicle. In automobiles, the transceiver is usually mounted to the underneath of the dash panel, with the microphone bracket beside it.
