Lynch FAA Radar Site
Lynch FAA Radar Site (1963-Active) - A Federal Aviation Administration (FAA) Long-Range Radar (LRR) site first established in 1963 on Black Mountain near Lynch, Harlan County, Kentucky. 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 a SAGE System ID of Z-232 and an FAA ID of QRI. Active FAA Radar Site.
The contract for construction of the Lynch FAA Radar Site was awarded on 9 Feb 1962 to Schanche Construction Company of St. Louis for $84,289. Work was scheduled to begin on 19 Feb 1962 and was scheduled to be completed by August 1963.
This site furnished radar track data to the FAA ARTCCs and to USAF Direction Centers. The initial FAA ARSR-2 search radar remained in operation until it was modified to become a (CARSR) radar with a 7172 antenna.
A FYQ-47 Common Digitizer was probably placed in service by February 1973 when the USAF/FAA FST-2 to FYQ-47 replacement program was completed. By 1990 the site was equipped with an ARSR-2 search radar and a CD-2A Common Digitizer. The Lynch CD-2A was scheduled to receive an upgrade kit to implement three level weather data processing in September 1992.
The nationwide replacement program converting FAA legacy radar systems to the CARSR radar configuration was completed by 17 Aug 2015 and Lynch FAA Radar Site was a part of that program. Legacy FAA radars underwent a Service Life Extension Program (SLEP) that replaced key components in the vintage ARSR-1, ARSR-2, FPS-20, FPS-66 and FPS-67 radars. The CARSR program replaced legacy klystron radar transmitters with a solid-state transmitter as well as renovating the radar receiver and signal processor. The CARSR modification also included common digitizer functionality making a separate common digitizer unnecessary. The Lynch FAA Radar Site is now operating with the CARSR radar. At the time of the CARSR changeout, the legacy radar in place was an ARSR-2 and the CARSR conversion included a 7172 Antenna. The secondary radar for the site is the ATCBI-6 Beacon set.
The radar site data is now available to the USAF/NORAD Battle Control System-Fixed (BCS-F) operations centers (EADS & WADS) as well as the FAA Indianapolis ARTCC (ZID) and adjacent ARTCCs. Other federal agencies have access to the data under the Homeland Security umbrella.
