View the publicly visible RadioDNS data provided by broadcasters in the United States:
- A RadioDNS lookup is performed on every radio station listed in the NRSC PI code database (both full service and translator), which will discover all the associated Service Information (SI) files, Services, and Bearers. When a call sign in the PI codes database is found in the RadioDNS directory, it is listed on this web site. If a call sign is found but not associated to a Service, its Service name shall be blank. This means it’s registered in RadioDNS but with incomplete information.
- Service Information (SI) file – SI files are .xml files which includes information about radio stations needed for hybrid radio services.
- Bearers in the context of RadioDNS are channels over which audio is conveyed – there are FM bearers (analog FM audio), HD Radio bearers (main and multicast channel digital audio) and streaming bearers (streaming audio delivered over the internet). Every bearer needs to be associated with a radio station and a Service.
- Services in the context of RadioDNS may be thought of as programs; since some broadcasters use a particular service (program) on multiple stations, the total services count is always less than the total FM bearer count.
