The Retevis RT24 uses digital encoding technology to transmit and receive signals. It utilizes Frequency Shift Keying (FSK) modulation to encode the audio and data signals, which allows for clear and secure communication. This encoding method helps to reduce interference and improve the overall audio quality of the communication. Additionally, the RT24 also employs digital encryption to further secure the transmitted data, making it suitable for professional and private use. **

The Retevis RT24 is coded using a unique identification code that is programmed into each radio. This code allows the radios to communicate with each other on the same frequency without interference from other radios. The coding also helps to ensure secure and private communication between users. Additionally, the RT24 has a built-in encryption feature that further enhances the security of the coded communication. **
