Kingdom Of Romania
The Kingdom of Romania ( ro, Regatul României) was a constitutional monarchy that existed in Romania from 13 March ( O.S.) / 25 March 1881 with the crowning of prince Karl of Hohenzollern-Sigmaringen as King Carol I (thus beginning the Romanian royal family), until 1947 with the abdication of King Michael I of Romania and the Romanian parliament's proclamation of the Romanian People's Republic. From 1859 to 1877, Romania evolved from a personal union of two vassal principalities (Moldavia and Wallachia) under a single prince to an autonomous principality with a Hohenzollern monarchy. The country gained its independence from the Ottoman Empire during the 1877–1878 Russo-Turkish War (known locally as the Romanian War of Independence), when it also received Northern Dobruja in exchange for the southern part of Bessarabia. The kingdom's territory during the reign of King Carol I, between 13 ( O.S.) / 25 March 1881 and 27 September ( O.S.) / 10 October 1914 is sometimes referred ...

Oltenia
Oltenia (, also called Lesser Wallachia in antiquated versions, with the alternative Latin names ''Wallachia Minor'', ''Wallachia Alutana'', ''Wallachia Caesarea'' between 1718 and 1739) is a historical province and geographical region of Romania in western Wallachia. It is situated between the Danube, the Southern Carpathians and the Olt river. History Ancient times Initially inhabited by Dacians, Oltenia was incorporated in the Roman Empire (106, at the end of the Dacian Wars; ''see Roman Dacia''). In 129, during Hadrian's rule, it formed Dacia Inferior, one of the two divisions of the province (together with Dacia Superior, in today's Transylvania); Marcus Aurelius' administrative reform made Oltenia one of the three new divisions (''tres Daciae'') as Dacia Malvensis, its capital and chief city being named Romula. It was colonized with veterans of the Roman legions. The Romans withdrew their administration south of the Danube at the end of the 3rd century and Oltenia wa ...

Radio Broadcasting
Radio broadcasting is transmission of audio (sound), sometimes with related metadata, by radio waves to radio receivers belonging to a public audience. In terrestrial radio broadcasting the radio waves are broadcast by a land-based radio station, while in satellite radio the radio waves are broadcast by a satellite in Earth orbit. To receive the content the listener must have a broadcast radio receiver (''radio''). Stations are often affiliated with a radio network which provides content in a common radio format, either in broadcast syndication or simulcast or both. Radio stations broadcast with several different types of modulation: AM radio stations transmit in AM ( amplitude modulation), FM radio stations transmit in FM (frequency modulation), which are older analog audio standards, while newer digital radio stations transmit in several digital audio standards: DAB (digital audio broadcasting), HD radio, DRM ( Digital Radio Mondiale).

Shortwave Radio
Shortwave radio is radio transmission using shortwave (SW) radio frequencies. There is no official definition of the band, but the range always includes all of the high frequency band (HF), which extends from 3 to 30 MHz (100 to 10 metres); above the medium frequency band (MF), to the bottom of the VHF band. Radio waves in the shortwave band can be reflected or refracted from a layer of electrically charged atoms in the atmosphere called the ionosphere. Therefore, short waves directed at an angle into the sky can be reflected back to Earth at great distances, beyond the horizon. This is called skywave or "skip" propagation. Thus shortwave radio can be used for communication over very long distances, in contrast to radio waves of higher frequency, which travel in straight lines ( line-of-sight propagation) and are limited by the visual horizon, about 64 km (40 miles). Shortwave broadcasts of radio programs played an important role in the early days of radi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amateur Radio Call Signs
Amateur radio call signs are allocated to amateur radio operators around the world. The call signs are used to legally identify the station or operator, with some countries requiring the station call sign to always be used and others allowing the operator call sign instead. The International Telecommunication Union (ITU) allocates call sign prefixes for radio and television stations of all types. Since 1927 these have been used to uniquely identify operators and locate amateur stations within a geographical region or country of the world. Call signs meant for amateur radio follow the ITU's Article 19, specifically 19.68 and 19.69. Prefixes are assigned internationally, and a separating numeral plus suffix are added by a national body to produce this unique identifier. These prefixes are agreed upon internationally, and are a form of country code. Each country must only assign call signs to its nationals or operators under its jurisdiction that begin with the characters allocate ...

Radio Wave
Radio waves are a type of electromagnetic radiation with the longest wavelengths in the electromagnetic spectrum, typically with frequencies of 300 gigahertz (GHz) and below. At 300 GHz, the corresponding wavelength is 1 mm (shorter than a grain of rice); at 30 Hz the corresponding wavelength is (longer than the radius of the Earth). Like all electromagnetic waves, radio waves in a vacuum travel at the speed of light, and in the Earth's atmosphere at a close, but slightly lower speed. Radio waves are generated by charged particles undergoing acceleration, such as time-varying electric currents. Naturally occurring radio waves are emitted by lightning and astronomical objects, and are part of the blackbody radiation emitted by all warm objects. Radio waves are generated artificially by an electronic device called a transmitter, which is connected to an antenna which radiates the waves. They are received by another antenna connected to a radio receiver, which p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amateur Radio
Amateur radio, also known as ham radio, is the use of the radio frequency spectrum for purposes of non-commercial exchange of messages, wireless experimentation, self-training, private recreation, radiosport, contesting, and emergency communications. 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.). The amateur radio service (''amateur service'' and '' amateur-satellite service'') is established by the International Telecommunication Union (ITU) through the Radio Regulations. National governments regulate technical and operational characteristics of transmissions and issue individual station licenses with a unique identifying call sign, which mus ...

Commander
Commander (commonly abbreviated as Cmdr.) is a common naval officer rank. Commander is also used as a rank or title in other formal organizations, including several police forces. In several countries this naval rank is termed frigate captain. Commander is also a generic term for an officer commanding any armed forces unit, for example "platoon commander", "brigade commander" and "squadron commander". In the police, terms such as "borough commander" and "incident commander" are used. Commander as a naval and air force rank Commander is a rank used in navies but is very rarely used as a rank in armies. The title, originally "master and commander", originated in the 18th century to describe naval officers who commanded ships of war too large to be commanded by a lieutenant but too small to warrant the assignment of a post-captain and (before about 1770) a sailing master; the commanding officer served as his own master. In practice, these were usually unrated sloops-of-war of no ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Romanian Land Forces
The Romanian Land Forces ( ro, Forțele Terestre Române) is the army of Romania, and the main component of the Romanian Armed Forces. In recent years, full professionalisation and a major equipment overhaul have transformed the nature of the Land Forces. The Romanian Land Forces was founded on . It participated in World War I, together with the Imperial Russian Army in actions against the Central Powers and, despite initial setbacks, won the decisive battles of Mărăști and Mărășești. During most of World War II (until August 23, 1944) Romanian forces supported the Axis powers, fighting against the Soviet Union on the Eastern Front. From August 1944 until the end of the war, Romania fought against Germany under the control of the Soviet Union. When the communists seized power after the Second World War, the army underwent reorganisation and sovietization. Following the Romanian Revolution of 1989, due to shortage of funds, many units were disbanded and much equipment was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
