Instead of the 500 kHz and 1 MHz frequencies common in shipboard radio at the time, Marconi was to use longwave frequencies of 37.5 kHz for transmission from Glace Bay, Cape Breton, Nova Scotia to Letterfrack and 54.5 kHz for transmission from Clifden, Ireland to Louisbourg in order to establish reliable transatlantic communication day and ...
RCA antique radios, and early color television receivers such as the RCA Merrill/CT-100, are among the more sought-after collectible radios and televisions, due to their popularity during the golden age of radio and the historic significance of the RCA name, as well as their styling, manufacturing quality and engineering innovations. Most ...
RCA Plugs for composite video (yellow) and stereo audio (white and red) RCA connectors , also known as phono connectors or phono plugs , are used for analog or digital audio or analog video. These were first used inside pre–World War II radio-phonographs to connect the turntable pickup to the radio chassis.
Radio-frequency (RF) engineering is a subset of electrical engineering involving the application of transmission line, waveguide, antenna, radar, and electromagnetic field principles to the design and application of devices that produce or use signals within the radio band, the frequency range of about 20 kHz up to 300 GHz.
These monitors featured BTSC system three-channel audio which had just been adopted by the Federal Communications Commission as the U.S. standard for stereo television transmission in 1984, the same year as the release of Dimensia. In 1985, RCA released a 40-inch projection monitor for the system with the 32 kilobyte microprocessors. This was ...

[1] The station was built in 1914 by Guglielmo Marconi (1874–1937) and taken over by RCA after World War I. [2] It is one of six Point Reyes sites listed on the National Register in ...
An antenna rotator (or antenna rotor) is a device used to change the orientation, within the horizontal plane, of a directional antenna. Most antenna rotators have two parts, the rotator unit and the controller. The controller is normally placed near the equipment which the antenna is connected to, while the rotator is mounted on the antenna ...
The RCA connector [3] is a type of electrical connector commonly used to carry audio and video signals. The name RCA derives from the company Radio Corporation of America, which introduced the design in the 1930s. [4] The connector’s male plug and female jack are called RCA plug and RCA jack. It is also called RCA phono connector [5] or phono ...
