It was used by Guglielmo Marconi during his work on radio waves, receiving the first ship-to-shore message from the East Goodwin lightship, the first ship-to-shore distress message (when a steamship ran into the same lightship, and the lighthouse relayed the message up the coast to the Walmer lifeboat), and the first international transmission (from Wimereux, France, in 1899).
Determination of the position of mobile vehicles, like f.e. vessels, using Syledis is accomplished by measurement of transit time of radio waves between mobiles and radio stations at known points.
Aguada transmission station is a facility of the US Navy for transmitting orders to submerged submarines near Aguada in Puerto Rico at 18°23'55"N 67°10'38"W by using radio waves in the low frequency range.
Earth-Moon-Earth communication, also known as moon bounce, is a radio communications technique which relies on the propagation of radio waves from an Earth-based transmitter directed via reflection from the surface of the Moon back to an Earth-based receiver.
In 1901 Fleming designed a transmitter for Guglielmo Marconi to attempt transmission of radio waves across the Atlantic from Poldhu, England, to Nova Scotia, Canada.
In 1979 he made Écoute voir... with Catherine Deneuve cast as a female detective investigating a gang looking to control people using radio waves.
They were used by Hertz to demonstrate the existence of electromagnetic waves, as predicted by James Maxwell and by Lodge and Marconi in the first research into radio waves.
While studying at the Sheffield Scientific School of Yale University, Hammond became interested in the new study of radio waves and he was taken under the wing of Alexander Graham Bell.
Ken's television credits include soap operas (Radio Waves, Close to Home) as well as stand-out episodes in the TV drama Mortimer's Patch including two episodes that were the most watched TV programme in New Zealand in their respective weeks: a feat that is unlikely to be repeated.
Night effect: radio waves reflected back by the ionosphere can cause signal strength fluctuations 30 to 60 nautical miles (54 to 108 km) from the transmitter, especially just before sunrise and just after sunset (more common on frequencies above 350 kHz)
A radio acoustic sounding system (RASS) is a system for measuring the atmospheric lapse rate using backscattering of radio waves from an acoustic wave front to measure the speed of sound at various heights above the ground.
Radio noise source, a device that emits radio waves at a certain frequency, used to calibrate radio telescope
This signal consists of true EM radiation (radio waves), and these leave the subject as RF radiation, but they are of such low power as to also not cause appreciable RF interference that can be picked up by nearby radio tuners (in addition, MRI scanners are generally situated in metal mesh lined rooms which act as Faraday cages.)
Reber Radio Telescope is a parabolic radio telescope built by astronomer Grote Reber in his back yard in Illinois in 1937, implementing an earlier proposal of Karl Jansky, the discoverer (1931) of radio waves emanating from the Milky Way.
Interplanetary scintillation, fluctuations of radio waves caused by the solar wind
The station was founded by Douglas and June Anderson as part of The Petros Radio Group who launched Discovery AM in 1994 and Radio Waves in 1995, then decided to go for the full scale local licence with the help of their neighbour George Mackintosh (who started Radio Tay in 1980) along with a consortium who also founded Kingdom FM in Fife with the assistance of IRG (The Independent Radio Group)
Radio, the wireless transmission of signals through free space by radio waves instead of cables, like telegraphs
