		Electric devices on them are fed via cables running through the coils of a parallel resonance circuit which is switched in parallel to the transmitter output.
		For high power transmitters in the MW range, masts with lengths around half of the radiated wavelength are preferred because they focus the radiated power better to the ground than constructions with heights of quarter wavelengths, which are preferred of economical reasons for low power medium wave transmitters.
		For longwave transmitters, however, the construction of masts with heights of half-wave wavelength is, because of economical reasons (and perhaps problems with the flight safety), in most cases impossible.

		The medium wave transmitter at Akraberg on 531 kHz has got a new transmitter tube and is now heard much better with their 100 kW signal (except during their news broadcast at 18.30-19.00 UT when the power is up at 200 kW).
		The tube was placed at the MW transmitter by Føroya Tele staff (Føroya Tele is the operator of this transmitter) and the transmitter resumed its regular service.
		Faroese Telecom, which is responsible for the maintenance of the transmitter, claims that it has requested funding for the replacement part in the past two years which has been denied by the Ministry of Trade and Industry who own the transmitter.

	DX LISTENING DIGEST 2002 ARCHIVE
		We have severe energy- related problems, in the rural zone of the transmitter plant, and operate our transmitters from a large group of accumulators, recharging them from rectifiers.
		So the operation of the system has considerably influenced the number of illegally used transmitters: the number of radioelectronic devices used without licences was 492 in 2000, and 1,020 in 2001.
		The engineer told us that the two transmitters are silent on July 23 till 25th during daytime, most likely 0610-1555 UT. The CW test on LF will be in the 136-137 kHz range of LF Ham R Band [secondary band usage], not on v153 kHz broadcasting band.

		However, many problems were encountered in the electronic and computer systems and so only two transmitters were taken into regular scheduling and the third was maintained for emergency usage, sometimes in hot standby.
		Ten years later again, two new transmitters at 250 kW were installed, and three years later again, the 300 kW transmitter VLK at Carnarvon was transferred to Darwin as VLT.
		The transmitter was in use at 0500-2300 serving a vast area from Rome to Barcelona along the Mediterranean Coast from Italy to France and Spain, also in daytime.

		The transmitter opened on this day was a 1 kW one compared to the previous one, which was only 1/2 kW.
		All the 10 KW transmitters were used for domestic broadcasting and all of them are inactive/discontinued broadcasting during the past few years.

	The Ultimate AM stereo - American History Information Guide and Reference
		There are two main classes of systems: independent sideband (ISB) systems, promoted principally by American broadcast engineer Leonard Kahn ; and quadrature amplitude modulation (QAM) multiplexing systems (conceptually closer to FM stereo), of which the best known is Motorola's C-QUAM.
		A famous European transmitter using AM stereo is Villebon sur Yvette on 864 kHz, which tranmits Radio Bleue.
		With the advent of digital radio technologies, particularly in-band on-channel systems, AM stereo will likely become obsolete.

		A better antenna would definitely help (this was on the radio in my truck, parked outside) and of course the state of propagation is everything.
		January, TDF broadcast Digital (DRM) and analogue tests on 1062 kHz from Villebon sur Yvette (12 miles south west Paris) with a power around 5 kW.
		The tests are not regular but at this time we have a continuous 4 minutes analogue program without identification, but with a dialogue in English with two people about "new technologies" and about "The futuroscope" in Poitiers (France).
