How do you modify your analog police scanner to hear digital?

To modify an analog police scanner to hear digital communications, you typically need to use a digital signal decoder or upgrade to a digital-capable scanner. Digital signals, such as P25 or DMR, require specific decoding that analog scanners cannot perform. Alternatively, some enthusiasts use software-defined radio (SDR) setups with appropriate software to receive and decode digital signals. However, ensure that you're compliant with local laws regarding scanning communications.
