: For those who want raw data, you can search license applications by location (ZIP code) or callsign to see what new bands have been allocated to local businesses or agencies.
: This tool specifically identifies potential digital audio frequencies by cross-referencing the FCC database, which is crucial for finding newer DMR or NXDN signals before they are widely listed.
: The gold standard for scanner enthusiasts. It features a comprehensive, user-vetted database of nationwide frequencies, including specific Talkgroups for digital trunked systems.
: Useful for locating physical towers within a specific radius of your address, helping you identify who is transmitting nearby. Common Digital Frequency Bands
Most modern public safety and commercial digital transmissions occur in these primary ranges:
The transition to is reshaping the radio hobby in 2026, driven by public safety agencies moving to complex trunked systems like P25 Phase II , DMR , and NXDN . While traditional analog scanning is fading in many urban areas, the availability of modern Software-Defined Radio (SDR) technology—found in top-tier scanners like the Uniden SDS100 and SDS200 —has made it possible to monitor these sophisticated digital signals with crystal-clear audio. Top Resources for Finding New Frequencies
Finding active digital channels requires using specialized databases rather than just "blindly" scanning the dial.
