Surface ships are more difficult to detect due to a number of factors such as signal return from waves (called in general ground clutter), distance to the horizon (due to the curvature of the Earth), elevation of the radar antenna, height of the target above the sea surface, and water vapor in the air. These factors serve to reduce the range at ...
The BC-348 is the 28 vdc powered version of the 14 vdc powered BC-224. The first version, the BC-224-A, was produced in 1936. [1] Installed in almost all USAAF (and some USN, some British and some Canadian) multi-engined transports and bombers used during the fifteen-year period from before World War II through the Korean War, BC-348 radio receivers were easy to operate and reliable.

The Videocomp was supported by a Spectra computer that ran the Page-1 and, later the Page-II and FileComp composition systems. RCA later sold the Videocomp rights to Information International Inc. RCA Victor became a major proponent of the 8-track tape cartridge, which it launched in 1965. Initially, the 8-track made a huge and profitable ...
The AN-FPQ 6 radar was built by RCA and was, effectively, a development of the AN-FPS 16. The Q6, as it was known by those who worked on it, was an amplitude comparison monopulse C-band radar, with a 2.8 MW peak klystron transmitter tunable from 5.4 to 5.8 GHz, which had a 9-meter parabolic antenna, having 52 dB gain, a 0.6 degree beam width, utilizing a Cassegrainian feed with a five horn ...
Three GE AN/FPS-50 Radar Sets were installed with antenna reflectors 165 by 400 feet (50 m × 122 m) that each weigh 1,000 short tons (910 t; 890 long tons). The "Building Two" middle transmitter building had the radar control room [ verification needed ] and room with the Sylvania AN/FSQ-28 Missile Impact Predictor Set .
Aspidistra broadcast on medium wave with 600 kW of power. The transmitter (originally 500 kW) had been built by RCA for WJZ radio in Newark, New Jersey, United States.But at the prompting of the United States Congress, spurred on by competition, [1] the Federal Communications Commission later imposed a 50-kW power limit on all US stations.
