In a conventional radio system, a frequency is used for each channel of communication. To hear transmissions for what you want to listen to, you must have the specific frequency for that channel programmed into your scanner. For example, a local police department’s dispatch channel would be on one frequency and their car-to-car channel would be on another separate frequency.
In small towns/cities, police and fire agencies will have several frequency that they will use for daily operations. You will find a separate frequency for dispatch, car-to-car. For fire departments, they may have dispatch, response coordination, on-scene "fireground" tactical, all on one frequencies.
In large towns/cities, police and fire agencies will have several frequencies that they will use for daily operations. You will find a separate frequency for dispatch, car-to-car, tactical use, detectives and so on. For fire departments, you will find separate frequencies for dispatch, response coordination, on-scene "fireground" tactical use, paramedics, and so on.
