United States Digital Radio Frequency Search Tools

The following search tools were created to help you find, scan, and identify digital radio frequencies in your area. All searches are by county and state. Data is from the FCC. More information is available on the individual search pages. I sincerely hope these tools are beneficial to you.

DMR Search The Digital Mobile Radio, DMR, search tool contains over 300,000 frequencies authorized for DMR voice use, including trunked system frequencies. DMR utilizes two-slot Time Division Multiple Access (TDMA). Newer consumer radio scanners and software radio solutions can receive DMR.
P25 Search The P25 search tool identifies Phase 1 and Phase 2 P25 Digital frequencies. Many of these frequencies will be part of trunked systems.
NXDN Search Search for frequencies authorized for NXDN voice use with this search tool. NXDN utilizes either a 12.5 kHz digital signal or a narrowband digital signal (6.25 kHz). The Whistler TRX scanners receive NXDN; there are also software radio programs that support NXDN decoding.
Quick Import The Quick Import tool prepares DMR, P25, or NXDN frequency data for quick and easy importing into scanner programming software. The Quick Import DMR Search produces data that is accepted by Whistler's EZ Scan, BuTel's ARC536, Uniden's BCDx36HP Sentinel, or FMP-DSD+.
