A tuner is an electronic device used to receive and tune in to radio broadcasts. It is designed to capture radio frequency (RF) signals transmitted by radio stations and convert them into audible sound. Tuners come in various forms, including standalone units, built-in tuners in audio systems, or even software-based tuners for computers and mobile devices. They typically feature a frequency tuning dial or digital display to select the desired radio station, and they may offer additional features such as presets, signal strength indicators, and stereo/mono modes. Tuners play a crucial role in providing access to a wide range of radio stations, allowing listeners to enjoy news, music, talk shows, and other programming. With the rise of internet radio and digital streaming services, modern tuners often incorporate online connectivity to access a broader range of audio content beyond traditional radio broadcasts.
