It was designated a National Historic Landmark District in 2012, in recognition of the site's long role in the development of modern civilian and military electronic communications.

[12] RCA sold the site to the Monmouth County Pleasure Seekers Club which was closely tied to Arthur H. Bell and the Ku Klux Klan.

[13] The Young People's Association for the Propagation of the Gospel purchased the Belmar station in 1936,[14] and The King's College opened in September 1938 — when it was denied accreditation it relocated (currently it is in the Empire State Building).

In 1941 the Belmar radio site was renamed the Evans Signal Laboratory[19] after Wall Township purchased the original Marconi buildings and the surrounding 93 acres for the Army to move the SCRL.

[citation needed] The Camp Evans lab used VT-158 tube(s), developed by Harold A. Zahl, to adapt SCR-268s for picket ships,[18] modified the SCR-268 into the SCR-602 which detected Japanese kamikazes[22] (producing 12 renumbered AN/TPQ-3 developmental models)[23] and on the SCR-584 tracking radar, did preliminary testing in December 1941 and added identification friend or foe.

[28] Camp Evans' black engineers contributed[specify] to electronic research, development, product distribution and training.

[29] For instance, Dr. Walter McAfee at Fort Monmouth[30] first calculated the speed of the moon during Project Diana[31] (it took 40 minutes to travel 15 deg, the width of the fixed radar beam rotating with the Earth).

[32] After the World War II Peenemünde V-2s tracked by the giant Würzburg radar had reached space and their telemetry had been received (e.g., at burnout); during moonrise on January 10, 1946, Project Diana transmitted VHF radar pulses through the ionosphere to the moon and detected the reflection[33] [34][35] using a modified version of an experimental SCR-271[36] at the right of center Camp Evans.

[39] The 1952 Army Radiation Dosimetry Laboratory was established in building 9401 which had an underground vault, a Van de Graff machine, and AN/UDM-1A caesium-137 and AN/UDM-1 cobalt-60 calibration sources and a 130,000 Curie Cobalt-60 pool irradiator for radiac development.

[citation needed] In 1957, replacement equipment, on the frame of a captured German Wertzburg [sic] Reise radar, erected at the Project Diana site helped track the Soviet Union's Sputnik[5] (cf.
