Best Police Scanner for Delaware: Frequencies, Systems & Recommendations
Delaware is the rare state where one system covers everyone.
A buyer's guide to Delaware's statewide P25 network and the right scanner for it
Delaware only has three counties, and that makes it one of the simplest states in the country to buy a scanner for. New Castle, Kent, and Sussex all ride the same statewide radio network, so there is no guessing which system covers your town. The catch is that Delaware just finished an eight-year, $63 million overhaul of that network, and Wilmington keeps its own city police system on top of it. Here is what changed, what is still open, and which Uniden scanner handles it best.
Delaware's Statewide System
Delaware's public safety radio has run on the State of Delaware Public Safety trunked system since 1993, an 800 MHz digital network built to APCO Project 25 (P25) standards. Unlike most states, this is not a patchwork of separate county systems. It is one network subdivided into three regions, one for each county, sharing a digital microwave backbone and three primary dispatch points at the county 911 centers.
In September 2025, the state completed a major modernization of that infrastructure, bringing the land mobile radio system fully up to current P25 standards after the legacy equipment became hard to maintain and parts became scarce. If you last researched Delaware scanning a few years ago, treat that information as outdated. There is also a second, separate layer worth knowing about: the Delaware Wireless Interoperability Network (DELWIN), which agencies use to communicate across jurisdictions during larger incidents rather than for day to day dispatch.
Because the whole state shares one architecture, a single P25 Phase II capable scanner covers Delaware State Police (DSP) and the great majority of county fire, EMS, and municipal police traffic no matter where you live or travel in the First State.
County by County
New Castle County
Delaware's most populous county, home to Wilmington, sits on the statewide 800 MHz P25 system for county and state agencies. Wilmington Police Department is the exception. It runs its own radio system separate from the statewide network, and a portion of that traffic is encrypted, which limits what you will hear from city patrol specifically compared to the surrounding county.
Kent County
Home to Dover, the state capital. Kent runs on the same statewide P25 trunked network as the rest of Delaware, with local control channels covering both dense areas near Dover and the surrounding farmland. Traffic here is largely unencrypted, and Kent shares mutual aid channels with both neighboring counties during weather events and larger incidents.
Sussex County
Delaware's largest county by land area, covering the beach towns along the coast. Sussex also rides the statewide 800 MHz P25 system for law enforcement, fire, and EMS. Listening here gets interesting in the summer and during hurricane season, when Coastal Highway traffic incidents and storm response bring heavy activity from multiple fire companies and mutual aid units at once.
How Much Is Encrypted?
Moderate, and mostly confined to one place. Delaware State Police and the county-level statewide system talkgroups remain largely accessible to a P25 scanner. The main exception is Wilmington PD, which keeps portions of its city system encrypted. That means the bulk of the state, including Dover, Sussex beach communities, and rural New Castle County, stays open, while Wilmington city patrol traffic specifically is more limited. This is a good example of why a single "is Delaware encrypted" answer does not tell the whole story. Always confirm current talkgroup status against RadioReference before you buy, since encryption decisions can change at the department level.
Which Scanner Should You Buy?
Since all three Delaware counties run on the same P25 trunked architecture, you do not need to shop differently based on where in the state you live. You need a scanner built for Phase II digital trunking, and Uniden's True I/Q platform is the strongest option on the market for exactly that.
Uniden SDS150
Our top pick for Delaware. Built-in GPS, phone control and audio, USB-C, a dock-style charging cradle, and the Waterfall display upgrade included from the box. If you travel between counties or want the least fiddling to get clean audio, this is the buy-once option.
Uniden SDS100
Same True I/Q decoding core as the SDS150 at a lower price. A great fit if you plan to keep the scanner mostly at home or in one vehicle and do not need built-in GPS or app control.
Not sure which counties to program, or want it ready to scan the moment it arrives? Our Expert Programming service covers Delaware State Police plus any county talkgroups you choose, so the scanner works out of the box instead of scanning every frequency in range.
"One statewide system means Delaware is one of the easiest states in the country to get right the first time, as long as you know Wilmington plays by its own rules."

Frequently Asked Questions
Do I need a different scanner for New Castle, Kent, and Sussex County?
No. All three counties run on the same statewide 800 MHz P25 trunked system, so one P25 Phase II capable scanner like the SDS150 or SDS100 covers the whole state.
Is Wilmington police radio encrypted?
Portions of it are. Wilmington PD operates its own city radio system separate from the statewide network, and part of that traffic is encrypted, which limits what a scanner picks up from city patrol specifically.
Is it legal to own a police scanner in Delaware?
Yes. Delaware has no state law restricting scanner ownership, use, or in-vehicle listening. Federal law still prohibits using scanner information to assist in committing a crime.
What changed with Delaware's 2025 radio upgrade?
The state completed an eight-year, $63 million project bringing its land mobile radio infrastructure fully up to current P25 standards, replacing aging equipment that had become difficult to maintain.
