FM DATABASE HELP
The WTFDA FM Radio Station Database is a listing of radio stations in the continental United States, Alaska, Hawaii and Puerto Rico, US territories AND Canada. The database is searchable on all major fields and can be sorted on any field by clicking on the field's header. Frequencies, callsigns, language, city, state/province, format, slogan and PI codes are all searchable.
This is the search box. Eight fields can be searched. Results can be viewed in either 25, 50 or 100 records per page. The default language on this database is English and empty fields denote English language. Select Spanish, French or other from the drop down menu. Fields are not case sensitive.
Enter your search data and press search. View your data, select clear form, enter new data and repeat.
Results are displayed below this display header. Each field is sortable. Most fields are self-explanatory except for a few fields. Place your cursor over the field name and an explanation should appear.
// - This short for parallel. Think of callsign // meaning "this station is // to another". If a callsign appears in the // field, then the first station is running the same programming as the second callsign. In the case of translators, station W212XX would be // to station WXXX, or WXXX is the originator for programming on W212XX.
The language field defauts to English and will be empty unless the station broadcasts in another language.
RDS info will be familiar to anyone using a receiver that displays RDS data. Each station using displays a unique PI code. PI codes are not shown on all RDS receivers and radios. Most DXers regard the logging of a station's PI code as a legitimate logging of a radio station. PTY codes indicate a station's format (program type). This is a standardized list and is mostly accurate however some stations may use an incorrect PTY code. Clear Channel FM stations also use their own PI codes beginning with 1xxx. These are referred to as bogus calls because decoding these results in the wrong callsigns.
The Mode field indicates monaural, stereo or HD reception. An empty field denotes stereo. HD or M is shown when the station broadcasts either in monaural or HD mode.
