Best Police Scanner for Boston (2026)
Boston Police Department went fully encrypted on August 9, 2025. BPD dispatch, tactical, and all operational channels are now dark to any scanner. But the Boston metro still has plenty of accessible communications — Boston Fire in the clear, state police patrol talkgroups on the statewide CoMIRS system, suburban departments, Logan Airport ATC, and regional mutual aid. Here's the honest picture of what you can still hear and which scanner you need to hear it.
Boston Police & BPD: Fully Encrypted Since August 9, 2025
Boston Police Department fully encrypted all radio communications on August 9, 2025. No scanner at any price can decode BPD transmissions. If you're buying a scanner specifically to hear BPD dispatch, stop — it will not work.

Logan Airport ATC
Boston Logan International Airport (BOS) air traffic control operates on public VHF airband frequencies. Approach, departure, and ground control are all receivable with any digital scanner on standard airband frequencies.
Massachusetts State Police
MSP operates on the statewide CoMIRS P25 system. Most troop patrol and dispatch talkgroups are in the clear as of June 2026, including in the Boston area — there's even a live MSP Metro Boston feed on Broadcastify. Check RadioReference for current talkgroup status.
Suburban Departments
Towns surrounding Boston — including Quincy, Newton, Waltham, Brookline, and Cambridge — operate on varying encryption levels. Many remain at least partially accessible on P25 digital systems. Status is mixed and can change.
Boston Fire
Boston Fire Department dispatch and fireground channels remain in the clear — multiple live Boston Fire feeds run on Broadcastify. Regional fire mutual aid channels are also accessible during multi-agency responses across Greater Boston.
MBTA Transit
Massachusetts Bay Transportation Authority operates rail, bus, and commuter rail communications. Some MBTA operational channels are accessible on their radio systems serving the Greater Boston area.
NOAA Weather
Boston area NOAA weather broadcasts on 162.400 MHz (WXL55 Boston) with storm alerts and marine forecasts for Massachusetts Bay, Cape Cod Bay, and surrounding coastal areas.
Scanner Recommendations for Boston
Which Scanner to Buy
You Need a P25 Digital Scanner
Nearly every law enforcement agency in the Boston metro operates on P25 digital radio, so you need a scanner capable of decoding P25 Phase I and Phase II trunked systems — the BCD436HP and SDS100 are both well-suited for the Boston metro. While BPD itself is encrypted, these scanners cover the state police, suburban agencies, and Boston Fire's conventional UHF channels.
Uniden SDS100: Best for Greater Boston Coverage
The SDS100's built-in GPS automatically loads nearby talkgroups as you move across the Boston metro and surrounding suburbs. If you're monitoring across multiple towns — or driving from Quincy to Cambridge to Waltham — the GPS-driven talkgroup loading keeps your scanner current without manual reprogramming. Battery-powered and highly portable.

For monitoring from a fixed location in the Boston suburbs, the BCD436HP delivers P25 Phase I and Phase II performance at a lower price point than the SDS100. Program it with CoMIRS state police talkgroups and suburban department talkgroups for your area. No GPS — you program it for a specific location — but the P25 decoding is identical.

The RTL-SDR V4 dongle with SDRTrunk software decodes P25 Phase I and Phase II on a Windows or Linux computer. At around $35, this is the lowest-cost entry into Greater Boston digital monitoring. It requires a computer running continuously and configuration work to set up CoMIRS and suburban talkgroups — but it works.

Frequently Asked Questions
When did Boston police radio go dark?
August 9, 2025. Boston Police Department fully encrypted all communications on that date. BPD now operates on an encrypted P25 system — no scanner at any price can decode BPD transmissions. This makes Boston one of the larger American cities to complete a full encryption transition.
What can I still hear in Boston?
Boston Fire dispatch (in the clear, with live online feeds), Logan Airport ATC on VHF airband, Massachusetts State Police (most patrol talkgroups are in the clear on the statewide CoMIRS P25 system), suburban departments in surrounding towns such as Quincy, Waltham, and Newton (status varies), MBTA Transit Police dispatch on CoMIRS, NOAA weather, and regional interoperability channels.
Do I need a digital scanner in Boston?
For police monitoring, yes. Law enforcement in the Boston metro — MSP and most suburban agencies — operates on P25 digital systems, so a P25-capable scanner such as the BCD436HP or SDS100 is required. Boston Fire still uses conventional UHF channels in the clear, which even analog scanners can receive, but a digital scanner covers both.
Is Massachusetts State Police encrypted?
Mostly not. MSP operates on the Commonwealth of Massachusetts Interoperable Radio System (CoMIRS), a statewide P25 network. As of June 2026, troop patrol and dispatch talkgroups are largely in the clear; encryption is limited to specialized functions. Check RadioReference.com for current CoMIRS talkgroup status by troop area.
What happened during the Boston Marathon after encryption?
The 2013 Boston Marathon bombing remains a landmark case in the public safety argument against encryption — open radio communications enabled real-time public awareness, media coordination, and civilian assistance during the response. BPD implemented full encryption in August 2025 despite that history, citing officer safety. Researchers and journalists continue to cite Boston as an example of encryption's accountability trade-offs.
