The LORAN-C transmitter Seneca was the master station of the Northeastern United States LORAN-C Chain (GRI 9960) and the X-Ray secondary station of the Great Lakes Chain (GRI 8970).
It was located within the Seneca Army Depot in Romulus, New York, south of Geneva.
[1] The station was operated by United States Coast Guard and was located on a 250-acre (1.0 km2) piece of land within the 10,587-acre (42.84 km2) facility.
It was the first LORAN station to use solid-state electronics versus vacuum tube components.
