The Maidenhead Locator System (a.k.a. QTH Locator and IARU Locator) is a geocode system used by amateur radio operators to succinctly describe their geographic coordinates, which replaced the deprecated QRA locator, which was limited to European contacts. [1]
The codes are intended for use by air, ground, sea, and space operations personnel at the tactical level. Code words that are followed by an asterisk (*) may differ in meaning from NATO usage. There is a key provided below to describe what personnel use which codes, as codes may have multiple meanings depending on the service.
The Federal Aviation Administration location identifier (FAA LID) is a three- to five-character alphanumeric code identifying aviation-related facilities inside the United States, though some codes are reserved for, and are managed by other entities.
