  • An Applicant callsign opens that callsign’s history; an Entity Name opens the applicant’s history.
  • A ULS File Number opens the application detail; a Receipt Date opens that day’s applications.
Notes:
  • Two dates or purposes in one row mean the application was amended or withdrawn: the latest change is on top, the original underneath.
  • “Granted” means the application was granted, not necessarily with this callsign.
  • Receipt dates more than a month old have a gray background.
