Longwave Transmitter Erching
The Erching transmitter was a longwave broadcasting facility of the Voice of America, established in 1953 near Erching, Bavaria, Germany. The transmitter used a guyed-steel-framework mast aerial, at the time of its inauguration the most powerful radio station in the world, with a transmitting power of 1000 kilowatts on 173 kHz. In 1973 the transmitter was shut down because of a relaxed political climate. In 1979 it was used for LORAN-D tests. The German Federal Post received a new frequency of 151 kHz for this transmitter and used it for broadcasting the programming of Deutschlandfunk. Because directional radiation was required at night time, a second aerial mast had to be erected. This was impossible because of the then-planned new Munich International Airport (opened in 1992), so the transmitter had to be shut down at night time. A new transmitter site was consequently placed at Aholming in 1985. After the completion of this new transmitter, Erching tower was shut down and d ...

Long-Wave Transmitter, Erching Copy
In radio, longwave, long wave or long-wave, and commonly abbreviated LW, refers to parts of the radio spectrum with wavelengths longer than what was originally called the medium-wave broadcasting band. The term is historic, dating from the early 20th century, when the radio spectrum was considered to consist of longwave (LW), medium-wave (MW), and short-wave (SW) radio bands. Most modern radio systems and devices use wavelengths which would then have been considered 'ultra-short'. In contemporary usage, the term ''longwave'' is not defined precisely, and its intended meaning varies. It may be used for radio wavelengths longer than 1,000 m i.e. frequencies up to 300 kilohertz (kHz), including the International Telecommunication Union's (ITU's) low frequency (LF, 30–300 kHz) and very low frequency (VLF, 3–30 kHz) bands. Sometimes the upper limit is taken to be higher than 300 kHz, but not above the start of the medium wave broadcast band at 520&nbs ...

Voice Of America
Voice of America (VOA or VoA) is the state-owned news network and international radio broadcaster of the United States of America. It is the largest and oldest U.S.-funded international broadcaster. VOA produces digital, TV, and radio content in 48 languages which it distributes to affiliate stations around the globe. It is primarily viewed by a non-American audience. VOA was established in 1942, and the VOA charter (Public Laws 94-350 and 103–415) was signed into law in 1976 by President Gerald Ford. VOA is headquartered in Washington, D.C., and overseen by the U.S. Agency for Global Media (USAGM), an independent agency of the U.S. government. Funds are appropriated annually under the budget for embassies and consulates. In 2016, VOA broadcast an estimated 1,800 hours of radio and TV programming each week to approximately 236.6 million people worldwide with about 1,050 employees and a taxpayer-funded annual budget of .

Bavaria
Bavaria ( ; ), officially the Free State of Bavaria (german: Freistaat Bayern, link=no ), is a state in the south-east of Germany. With an area of , Bavaria is the largest German state by land area, comprising roughly a fifth of the total land area of Germany. With over 13 million inhabitants, it is second in population only to North Rhine-Westphalia, but due to its large size its population density is below the German average. Bavaria's main cities are Munich (its capital and largest city and also the third largest city in Germany), Nuremberg, and Augsburg. The history of Bavaria includes its earliest settlement by Iron Age Celtic tribes, followed by the conquests of the Roman Empire in the 1st century BC, when the territory was incorporated into the provinces of Raetia and Noricum. It became the Duchy of Bavaria (a stem duchy) in the 6th century AD following the collapse of the Western Roman Empire. It was later incorporated into the Holy Roman Empire, became an ind ...

LORAN
LORAN, short for long range navigation, was a hyperbolic radio navigation system developed in the United States during World War II. It was similar to the UK's Gee system but operated at lower frequencies in order to provide an improved range up to with an accuracy of tens of miles. It was first used for ship convoys crossing the Atlantic Ocean, and then by long-range patrol aircraft, but found its main use on the ships and aircraft operating in the Pacific theater during World War II. LORAN, in its original form, was an expensive system to implement, requiring a cathode ray tube (CRT) display. This limited use to the military and large commercial users. Automated receivers became available in the 1950s, but the same improved electronics also opened the possibility of new systems with higher accuracy. The U.S. Navy began development of Loran-B, which offered accuracy on the order of a few tens of feet, but ran into significant technical problems. The U.S. Air Force worked on a ...

Deutsche Bundespost
The Deutsche Bundespost (German federal post office) was a German state-run postal service and telecommunications business founded in 1947. It was initially the second largest federal employer during its time. After staff reductions in the 1980s, the staff was reduced to roughly 543,200 employees in 1985. The corporation was dissolved in 1995 under two rounds of postal reforms that took place in the German Post Office in 1989 and 1995, respectively. Following the reforms, the former Deutsche Bundespost was broken into three publicly traded corporations: Deutsche Post AG (German Post), Deutsche Telekom (German Telecom), and Deutsche Postbank AG (German Post Bank). History Created in 1947 in the Trizone as a successor to the ''Reichspost'' (German imperial post office), until 1950 the enterprise was called ''Deutsche Post'' (German post office). Until 1989, the ''Deutsche Bundespost'' was a state-owned operation. Organization The ''Bundespost'' was developed according to a ...

Deutschlandfunk
Deutschlandfunk (DLF, ''Broadcast Germany'') is a public-broadcasting radio station in Germany, concentrating on news and current affairs. It is one of the four national radio channels produced by Deutschlandradio. History Broadcasting in the Federal Republic of Germany is reserved under the Basic Law (constitution) to the states. This means that all public broadcasting is regionalised. National broadcasts must be aired through the national consortium of regional public broadcasters ( ARD) or authorized by a treaty negotiated between the states. In the 1950s, the German Democratic Republic (GDR) began broadcasting its Deutschlandsender station on longwave. In response to this, the then-Nordwestdeutscher Rundfunk applied for a licence to operate a similar longwave service on behalf of the ARD. This was granted in 1956 and operated as Deutscher Langwellensender ("German Longwave Station"). On 29 November 1960, the federal government under Konrad Adenauer created ''Deutschlan ...

Aholming Transmitter
Aholming transmitter was a facility for formerly broadcasting the Program of Deutschlandfunk on 207 kHz with a power of 500 kW at day and 250 kW at night between Aholming and Ottmaring in Bavaria. It was (finally) shut down in the early Morning hours of January 1, 2015. It was demolished in 2018. The Aholming Transmitter, which could be received in most parts of Europe, was built between 1986 and 1988 as a Replacement for the older Erching transmitter. This became necessary as the Nighttime Operation on 207 kHz requires, according to the Geneva Frequency Plan a directional Radiation Pattern for whose Realization a second Mast was required. This Mast could not be built on the site of the former Erching, as it had to be cleared from tall Structures as in its Proximity the new Airport of Munich was under construction. The Aholming Transmitter, which entered into service on January 1, 1989, uses a directional antenna consisting of two grounded masts, which are g ...

List Of Masts
The tallest structure in the world is the Burj Khalifa skyscraper at . Listed are guyed masts (such as telecommunication masts), self-supporting towers (such as the CN Tower), skyscrapers (such as the Willis Tower), oil platforms, electricity transmission towers, and bridge support towers. This list is organized by absolute height. See List of tallest buildings and structures, List of tallest freestanding structures and List of tallest buildings and List of tallest towers for additional information about these types of structures. Terminology Terminological and listing criteria follow Council on Tall Buildings and Urban Habitat definitions. Guyed masts are differentiated from towers – the latter not featuring any guy wires or other support structures; and buildings are differentiated from towers – the former having at least 50% of occupiable floor space although both are self-supporting structures.
