Trunking scanners are designed to monitor modern public safety radio systems used by many police, fire, EMS, and emergency agencies across the country. These advanced scanners automatically follow conversations across shared frequencies and can monitor many analog, digital, and APCO P25 trunked systems. Browse handheld, mobile, and base trunking scanners below to compare features and find the right scanner for your monitoring needs.
Many cities, counties and even entire states in the U.S. and Canada use "trunking" radio systems for public safety communications and these systems are usually digital as well. Trunking allows agencies to provide dozens or even hundreds of groups of users to share a small number of computer-controlled radio frequencies. The scanner radios above are all trunking models which also can scan regular (conventional) radio systems. The most expensive models are also digital which is required on many trunked and non-trunked systems. Visit the

Frequently asked questions about Trunking ScannersQ: What is a trunking scanner?
A: A trunking scanner is a scanner radio designed to follow conversations on trunked radio systems used by many police, fire, EMS, and public safety agencies. Unlike conventional scanners that monitor fixed frequencies, trunking scanners automatically track conversations as they move between shared radio channels.
Q: Do I need a trunking scanner in my area?
A: Many cities, counties, and statewide radio systems now use trunked communications. If your local public safety agencies operate on a trunked system, you’ll need a compatible trunking scanner to properly monitor their transmissions. Some areas may also require digital or APCO P25 support depending on the system type.
Q: Can trunking scanners also receive regular analog channels?
A: Yes. Most trunking scanners can also monitor traditional analog and conventional radio systems in addition to trunked systems. Many newer models also support digital APCO P25 Phase I and Phase II communications for expanded monitoring capability and long-term compatibility.
