Given the question: Information: - Video is an electronic medium for the recording, copying, playback, broadcasting, and display of moving visual media. - An audience is a group of people who participate in a show or encounter a work of art, literature (in which they are called "readers"), theatre, music (in which they are called "listeners"), video games (in which they are called "players"), or academics in any medium. Audience members participate in different ways in different kinds of art; some events invite overt audience participation and others allowing only modest clapping and criticism and reception. - In electronics, a vacuum tube, an electron tube, or just a tube (North America), or valve (Britain and some other regions), is a device that controls electric current between electrodes in an evacuated container. Vacuum tubes mostly rely on thermionic emission of electrons from a hot filament or a cathode heated by the filament. This type is called a thermionic tube or thermionic valve. A phototube, however, achieves electron emission through the photoelectric effect. Not all electronic circuit valves/electron tubes are vacuum tubes (evacuated); gas-filled tubes are similar devices containing a gas, typically at low pressure, which exploit phenomena related to electric discharge in gases, usually without a heater. - Radio is the technology of using radio waves to carry information, such as sound, by systematically modulating properties of electromagnetic energy waves transmitted through space, such as their amplitude, frequency, phase, or pulse width. When radio waves strike an electrical conductor, the oscillating fields induce an alternating current in the conductor. The information in the waves can be extracted and transformed back into its original form. - A radio station is a set of equipment necessary to carry on communication via radio waves. Generally, it is a receiver or transmitter, an antenna, and some smaller additional equipment necessary to operate them. Radio stations play a vital role in communication technology as they are heavily relied on to transfer data and information across the world. - Freinberg is a municipality in the district of Scharding in Upper Austria, Austria. The municipality has an area of 20 square kilometers and population of 1494 (on 31 December 2005). - Frank Conrad (May 4, 1874 December 10, 1941) was an electrical engineer, best known for radio development, including his work as a pioneer broadcaster. He worked for the Westinghouse Electrical and Manufacturing Company in East Pittsburgh, Pennsylvania for half a century. His experimental radio station provided the inspiration, and he acted in an advisory role, for the establishment of Westinghouse's first broadcasting service, over radio station KDKA. - A T-antenna, T-aerial, flat-top antenna, or top-hat antenna is a vertically polarized simple wire radio antenna used in the VLF, LF, MF and shortwave bands. T-antennas are widely used as transmitting antennas for amateur radio stations, long wave and medium wave broadcasting stations. They are also used as receiving antennas for shortwave listening. - The Freinberg Transmitter is a broadcasting transmitter on the Freinberg near Linz . It was established in 1928 as medium wave broadcasting station and used until 1936 a T - antenna , which hung up on two guyed masts , which were 45 metres tall . In 1936 , the T - antenna was replaced by a 165 metre tall mast , insulated against ground . In summer 1950 , the antenna mast was shortened to 120 metres , because it was too long for the new frequency and would have a bad radiation diagram . In October 1957 , the mast was again extended to 146 metres and in 1965 the transmitters were replaced by a new device . At the beginning of the 1980s , medium wave broadcasting ceased at Freinberg . The mast is now used for FM transmission . - A telephone, or phone, is a telecommunications device that permits two or more users to conduct a conversation when they are too far apart to be heard directly. A telephone converts sound, typically and most efficiently the human voice, into electronic signals suitable for transmission via cables or other transmission media over long distances, and replays such signals simultaneously in audible form to its user. - Broadcasting is the distribution of audio and/or video content or other messages to a dispersed audience via any electronic mass communications medium, but typically one using the electromagnetic spectrum (radio waves), in a one-to-many model. Broadcasting began with AM radio, which came into popular use around 1920 with the spread of vacuum tube radio transmitters and receivers. Before this, all forms of electronic communication (early radio, telephone, and telegraph) were one-to-one, with the message intended for a single recipient. The term "broadcasting", borrowed from the agricultural method of sowing seeds in a field by casting them broadly about, was coined by either KDKA manager Frank Conrad or RCA historian George Clark around 1920 to distinguish this new activity of "one-to-many" communication; a single radio station transmitting to multiple listeners. - Upper Austria (; Austro-Bavarian: "Obaostarreich") is one of the nine states or "Bundeslander" of Austria. Its capital is Linz. Upper Austria borders on Germany and the Czech Republic, as well as on the other Austrian states of Lower Austria, Styria, and Salzburg. With an area of and 1.437 million inhabitants, Upper Austria is the fourth-largest Austrian state by land area and the third-largest by population. - Linz is the third-largest city of Austria and capital of the state of Upper Austria. It is located in the north centre of Austria, approximately south of the Czech border, on both sides of the River Danube. The population of the city is , and that of the Greater Linz conurbation is about 271,000. - An electromagnet is a type of magnet in which the magnetic field is produced by an electric current. The magnetic field disappears when the current is turned off. Electromagnets usually consist of insulated wire wound into a coil. A current through the wire creates a magnetic field which is concentrated in the hole in the center of the coil. The wire turns are often wound around a magnetic core made from a ferromagnetic or ferrimagnetic material such as iron; the magnetic core concentrates the magnetic flux and makes a more powerful magnet. - Radio waves are a type of electromagnetic radiation with wavelengths in the electromagnetic spectrum longer than infrared light. Radio waves have frequencies as high as 300GHz to as low as 3kHz, though some definitions describe waves above 1 or 3 GHz as microwaves, or include waves of any lower frequency. At 300 GHz, the corresponding wavelength is , and at 3 kHz is . Like all other electromagnetic waves, they travel at the speed of light. Naturally occurring radio waves are generated by lightning, or by astronomical objects. - A conurbation is a region comprising a number of cities, large towns, and other urban areas that, through population growth and physical expansion, have merged to form one continuous urban or industrially developed area. In most cases, a conurbation is a polycentric urbanised area, in which transportation has developed to link areas to create a single urban labour market or travel to work area. - Amateur radio (also called ham radio) describes the use of radio frequency spectrum for purposes of non-commercial exchange of messages, wireless experimentation, self-training, private recreation, radiosport, contesting, and emergency communication. The term "amateur" is used to specify "a duly authorised person interested in radioelectric practice with a purely personal aim and without pecuniary interest;" (either direct monetary or other similar reward) and to differentiate it from commercial broadcasting, public safety (such as police and fire), or professional two-way radio services (such as maritime, aviation, taxis, etc.). - Communication (from Latin "commnicre", meaning "to share") is the act of conveying intended meanings from one entity or group to another through the use of mutually understood signs and semiotic rules. - The electromagnetic spectrum is the collective term for all known frequencies and their linked wavelengths of the known photons (electromagnetic radiation). The "electromagnetic spectrum" "of an object" has a different meaning, and is instead the characteristic distribution of electromagnetic radiation emitted or absorbed by that particular object. - Medium wave (MW) is the part of the medium frequency (MF) radio band used mainly for AM radio broadcasting. For Europe the MW band ranges from 526.5kHz to 1606.5kHz, using channels spaced every 9kHz, and in North America an extended MW broadcast band ranges from 525kHz to 1705kHz, using 10kHz spaced channels.
