	US Bazaar.com : Encyclopedia Pages : Radio transmitter
		In industrial process control a "transmitter" is any device which converts measurements from a sensor into a signal to be received, usually sent via wires, by some display or control device located a distance away.
		Transmitters may be damaged if operated without an antenna, so protection circuits must detect the loss of the antenna and switch off the transmitter immediately.
		To reduce transmission line loss the transmitter building is usually immediately adjacent to the antenna for VHF and UHF sites, but for lower frequencies it may be desirable to have a distance of a few score or several hundred metres between the building and the antenna.

	Transmitter Information - fm transmitter
		For example, in industrial process control a "transmitter" is any device which converts measurements from a sensor into a signal to be received, usually sent via transmitter wires, by some infrared transmitter display or control device located a distance away.
		Often the transmitter frequency build a fm transmitter fiber optic transmitter tv transmitter is not the frequency produced by the oscillator, but one of its harmonics.
		A minimum distance, which depends on the transmitter frequency, radio transmitter transmitter power, and the design of the transmitting antennas, is required to protect people from the radio frequency energy.

		In industrial process control a "transmitter" is any device which converts measurements from a sensor into a signal to be received, usually sent via wires, by some display or control device located a distance away.
		For microwave transmitters, special semiconductor components or vacuum tubes (such as the klystron, cavity magnetron or TWT) are needed, because signals of these frequencies and power levels cannot be processed with normal semiconductors.
		To reduce transmission line loss the transmitter building is usually immediately adjacent to the antenna for VHF and UHF sites, but for lower frequencies it may be desirable to have a distance of a few score or several hundred metres between the building and the antenna.

	Transmitter
		A transmitter usually has a power supply, an oscillator, a modulator, and amplifiers for audio (AF), intermediate frequency (IF) and radio frequency (RF).
		For example, in industrial process control a "transmitter" is any device which converts measurements from a sensor into a signal to be received, usually sent via wires, by some display or control device located a distance away.
		Further, the operating voltages, modulation factor, frequency and other transmitter parameters are monitored for protection and diagnostic purposes.

		The earliest radio transmitters were all longwave transmitters, because propagation of radio waves of higher frequency was not yet understood.
		In Europe, North Africa and Asia, longwave radio frequencies in the band 148.5 to 283.5 kHz are used for domestic and international broadcasting.
		In North America during the 1970's the longwave frequencies 167, 179 and 191KHz were used for a short lived network of Civil defence emergency broadcsting stations with stations at Ault, Colorado and Cambridge, Kansas.

	Allouis longwave transmitter - Wikipedia, the free encyclopedia
		The Allouis longwave transmitter first entered service, as France's central longwave transmitter, in 1939.
		Prior to its destruction in 1944 by German forces, it used an aerial with four masts and a transmitter rated at 500 kilowatts.
		Since 1977 the Allouis transmitter in Allouis has been used to transmit not only the France Inter radio channel, but also AMDS-mode time signals.

		transmitter, London]]A transmitter (sometimes abbreviated XMTR) is an electronic device which with the aid of an antenna propagates an electromagnetic signal such as radio, television, or other telecommunications.
		A good example of this is Waltham which broadcasts digital MUXES 5 & 6 on the same frequencies as Sandy Heath, another transmitter 50 miles SSE of it.
		For most large stations in the VHF- and UHF-range, the transmitter power is no more than 20% of the ERP.For VLF, LF, MF and HF the ERP is typically not determined separately.

	Paris - Eiffel Tower
		At the time of its construction in 1889, the Eiffel Tower was the tallest structure in the world, a title it retained until 1930, when New York City's Chrysler Building (319 m/1046 feet tall) was completed (although the Eiffel Tower was still taller if the respective spires of the two structures were excluded).
		The Eiffel Tower is the second-highest structure in France, after the 350 m Allouis longwave transmitter.
		They were connected to long-wave transmitters which were in small bunkers; in 1909, a permanent underground radio center was built near the south pillar of the tower and still exists today.

		Unless indicated otherwise, the accuracy of the serial timecode is in the range of a millisecond or two relative to UTC when corrected for the receiver internal delay and signal propagation delay from the transmitter to the receiver.
		Larger phase and frequency variation observed at the receiver are due to summation of ground and space waves.
		These clocks are set an arbitrary 100 microseconds ahead of UTC (Rugby) to cater for the unavoidable delays in drive generators and transmitters.

		We spotted the transmitter building next to the south pillar of the tower (it's mostly underground, but some power and ventilation equipment sits above the facility), and tried to follow the transmission lines up the tower.
