In telecommunications, [1] particularly in radio frequency engineering, signal strength refers to the transmitter power output as received by a reference antenna at a distance from the transmitting antenna. High-powered transmissions, such as those used in broadcasting, are expressed in dB-millivolts per metre (dBmV/m).
The show originated on Philips Radio's PCJJ shortwave station in 1928, continuing until 1940. After World War II Radio Netherlands broadcast the show from 1946 until it terminated in 1995. Producer and presenter Keith Perron of Taiwan-based PCJ Media revived Happy Station from 2009 until 2020.
Television interference (TVI) is a particular case of electromagnetic interference which affects television reception. Many natural and man-made phenomena can disrupt the reception of television signals. These include naturally occurring and artificial spark discharges, and effects due to the operation of radio transmitters.
A broadcast signal intrusion is the hijacking of broadcast signals of radio, television stations, cable television broadcast feeds or satellite signals without permission or licence. Hijacking incidents have involved local TV and radio stations as well as cable and national networks.
Live radio is sound transmitted by radio waves, as the sound happens. Modern live radio is probably [original research?] most used to broadcast sports but it is also used to transmit local news and traffic updates. Most radio that people listen to today is pre-recorded music, and the days of solely live broadcast music are generally not as present.
By 1928, RCA had scrapped plans for more longwave transmitters and instead built six shortwave transmitters, 2XT and WTT at 40 kw and WBU, WIK, WQO and WLL at 20 kw. The Radio Central complex was used to relay international broadcast programming received by, or sent from, RCA's broadcast stations in the United States.

For reception at frequencies below 1.6 MHz, which includes long and medium waves, loop antennas are popular because of their ability to reject locally generated noise. By far the most common antenna for broadcast reception is the ferrite-rod antenna, also known as a loopstick antenna. The high permeability ferrite core allows it to be compact ...
