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.

Two dates or purposes in one row mean the application was amended or withdrawn: the latest change is on top, the original underneath.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.
