Motorola CP1300

Creating a comprehensive frequency list for the requires a nuanced approach. Unlike a standard broadcast radio, the CP1300 is a programmable, professional two-way radio. It does not come with fixed channels; rather, it is a "blank slate" that is programmed via computer software (CPS) to operate on specific frequencies allocated by local authorities.

• Tone Frequencies: 67.0 Hz, 71.9 Hz, 74.8 Hz, 77.0 Hz, 79.7 Hz, 82.2 Hz, 85.4 Hz, 88.5 Hz
• PL Frequencies: 67.0 Hz, 107.2 Hz, 123.0 Hz, 127.3 Hz, 131.8 Hz, 136.5 Hz, 141.3 Hz, 146.2 Hz

Hotels typically use UHF for better penetration through guest room walls.

1. Rx (Receive) Frequency: The specific frequency the radio listens on.
2. Tx (Transmit) Frequency: The frequency the radio broadcasts on. In simplex operation, the Rx and Tx frequencies are the same. In repeater operations, they differ to extend range.
3. CTCSS/DCS Codes (Privacy Codes): Often mistaken for security features, these sub-audible tones (Continuous Tone-Coded Squelch System or Digital-Coded Squelch) act as a gatekeeper. They ensure the radio only opens the speaker when it receives a signal accompanied by the correct specific tone. A comprehensive frequency list must include these codes; entering the frequency without the correct CTCSS tone will result in hearing silence, even if signals are present.
4. Bandwidth: The CP1300 supports both Narrowband (12.5 kHz) and Wideband (25 kHz) settings. Modern regulations in many regions mandate narrowband usage to maximize spectrum efficiency.
