La Grange FAA Radar Site

 (1959-Active) - A Federal Aviation Administration (FAA) Long Range Radar (LLR) site first established in 1959 near La Grange, La Grange County, Indiana. The site is used to identify and track military and civilian aircraft movements within a 200-mile radius and to provide air-ground radio communication with those aircraft. Assigned an FAA ID of QTZ. Active FAA Radar Site.

History
This site became an active FAA radar site in August 1959, furnishing radar track data to the FAA ARTCC's and to USAF Direction Centers. The initial FAA ARSR-1 search radar was eventually modified to an ARSR-1E configuration and remained in operation until it was modified to become a Common Air Route Surveillance Radar (CARSR) reportedly on 26 Jun 2012.

By 1990 the site was equipped with an ARSR-1E search radar and a CD-2A Common Digitizer. The La Grange CD-2 was scheduled to receive an upgrade kit to implement three level weather data processing on 14 Sep 1990.

CARSR Radar
At the time of the CARSR changeout, the legacy radar in place was an ARSR-1E and the CARSR conversion included a 7172 Antenna. The secondary radar for the site is the ATCBI-6 Beacon set.
