J1HD - Southern California 🇺🇸

The call letters 'J1HD' do not align with the Federal Communications Commission's (FCC) assignment conventions for radio stations in the United States. US radio station call letters begin with 'K' or 'W,' depending on their location relative to the Mississippi River; 'J' call letters are used in other countries. Therefore, 'J1HD' is almost certainly not a legitimate FCC-licensed radio station in Southern California. The 'HD' portion might suggest HD Radio technology, a digital broadcasting method used in the US, but this does not affect the base call letters. Possible explanations for encountering 'J1HD' include a typo, an internal designation, or confusion with an internet radio station which is not regulated by the FCC. If you are seeking a specific radio station, search by frequency, station name, or genre. Websites such as Radio-Locator.com can assist you in finding radio stations by location and format. Double-check your original source for 'J1HD' and consider these alternative search methods.
