Amateur Station Operator's Certificate
Amateur radio or ham radio is practised by more than 22,000 licensed users in India. The first amateur radio operator was licensed in 1921, and by the mid-1930s, there were around 20 amateur radio operators in India. Amateur radio operators played an important part in the Indian independence movement with the establishment of illegal pro-independence radio stations in the 1940s. The three decades after India's independence saw only slow growth in the number of operators until the then Prime Minister of India and amateur radio operator, Rajiv Gandhi (VU2RG), waived the import duty on wireless equipment in 1984. Since then, numbers have picked up, and , there were more than 16,000 operators in the country. Amateur radio operators have played a vital role during disasters and national emergencies such as earthquakes, tsunamis, cyclones, floods, and bomb blasts, by providing voluntary emergency communications in the affected areas.

Indian Independence Movement
The Indian independence movement was a series of historic events with the ultimate aim of ending British Raj, British rule in India. It lasted from 1857 to 1947. The first nationalistic revolutionary movement for Indian independence emerged from Bengal. It later took root in the newly formed Indian National Congress with prominent moderate leaders seeking the right to appear for Indian Civil Service (British India), Indian Civil Service examinations in British India, as well as more economic rights for natives. The first half of the 20th century saw a more radical approach towards self-rule by the Lal Bal Pal, Lal Bal Pal triumvirate, Aurobindo Ghosh and V. O. Chidambaram Pillai. The final stages of the independence struggle from the 1920s was characterized by Congress' adoption of Mahatma Gandhi's policy of non-violence and Salt March, civil disobedience.

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 ...

High Frequency
High frequency (HF) is the ITU designation for the range of radio frequency electromagnetic waves (radio waves) between 3 and 30 megahertz (MHz). It is also known as the decameter band or decameter wave as its wavelengths range from one to ten decameters (ten to one hundred meters). Frequencies immediately below HF are denoted medium frequency (MF), while the next band of higher frequencies is known as the very high frequency (VHF) band. The HF band is a major part of the shortwave band of frequencies, so communication at these frequencies is often called shortwave radio. Because radio waves in this band can be reflected back to Earth by the ionosphere layer in the atmosphere – a method known as "skip" or " skywave" propagation – these frequencies are suitable for long-distance communication across intercontinental distances and for mountainous terrains which prevent line-of-sight communications. The band is used by international shortwave broadcasting stations ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Maharaja Of Mysore
The maharaja of Mysore was the king and principal ruler of the southern Indian Kingdom of Mysore and briefly of Mysore State in the Indian Dominion roughly between the mid- to late-1300s and 1950. In title, the role has been known by different names over time, from ''poleygar'' (Kannada, ''pāLegāra'', for 'chieftain') during the early days of the fiefdom to ''raja'' (Sanskrit and Kannada, king–of especially a small region) during its early days as a kingdom to ''maharaja'' (Sanskrit and Kannada, reatking–of a formidable kingdom) for the rest of its period. In terms of succession, the successor was either a hereditary inheritor or, in case of no issue, handpicked by the reigning monarch or his privy council. All rulers under the Sanskrit-Kannada titles of ''raja'' or ''maharaja'' were exclusively from the house of Wadiyar. As India gained Independence from British Crown in 1947, Crown allies, most of which were princely India, ceded into the Dominion of India by 1950. ...

DX-pedition
A DX-pedition is an expedition to what is considered an exotic place by amateur radio operators and DX listeners, typically because of its remoteness, access restrictions, or simply because there are very few radio amateurs active from that place. This could be an island, a country, or even a particular spot on a geographical grid. ''DX'' is a telegraphic shorthand for "distance" or "distant" (see DXing). History Early DX-peditions were simply exploratory and geographical expeditions in the late 1920s and 1930s, in which one or more radio amateurs participated to provide long-distance communications. At the same time they communicated with fellow radio amateurs who wanted to contact a new country. Most notable are the Antarctic expeditions of Admiral Byrd. Another example is the voyage of the schooner ''Kaimiloa'', which traveled the South Pacific in 1924. While the ship's wealthy owners enjoyed the islands, an amateur radio operator kept contact with, and sent QSL cards to, e ...

Mahatma Gandhi
Mohandas Karamchand Gandhi (; ; 2 October 1869 – 30 January 1948), popularly known as Mahatma Gandhi, was an Indian lawyer, anti-colonial nationalist Quote: "... marks Gandhi as a hybrid cosmopolitan figure who transformed ... anti-colonial nationalist politics in the twentieth-century in ways that neither indigenous nor westernized Indian nationalists could." and political ethicist Quote: "Gandhi staked his reputation as an original political thinker on this specific issue. Hitherto, violence had been used in the name of political rights, such as in street riots, regicide, or armed revolutions. Gandhi believes there is a better way of securing political rights, that of nonviolence, and that this new way marks an advance in political ethics." who employed nonviolent resistance to lead the successful campaign for India's independence from British rule, and to later inspire movements for civil rights and freedom across the world.
