Encryption means frequencies in your area are blocked and NOT listenable.


There are 2 types of encryption:

  1. PARTIAL encryption
    1. Example: SWAT team, FBI, narcotics, etc.
    2. Use: Most areas have partial encryption
  2. FULL encryption
    1. Example: 100% of Pennsylvania State Police are encrypted
    2. Use: Few areas in the US have full encryption


There are no scanners available that can monitor encryption; there are no tricky loopholes to work around full encryption*.


If your area has partial encryption there are still plenty of monitorable frequencies—just not encrypted channels.

*Breaking encryption codes is a federal offense.
