ILERA
The International League of Esperantist Radio Amateurs ( eo, Internacia Ligo de Esperantista Radioamatoroj, ILERA). It was founded in 1970. It organizes radio programs in Esperanto Esperanto ( or ) is the world's most widely spoken constructed international auxiliary language. Created by the Warsaw-based ophthalmologist L. L. Zamenhof in 1887, it was intended to be a universal second language for international communi ... and publishes the ''ILERA bulletin''. Activities and practices Likely frequencies for Esperanto conversations on the air are 1866, 3766, 7066, 14266, 28766 kHz for Voice ( SSB), and 3640, 14166, 28266 kHz for CW, generally on weekends, according to Net Schedules published on the ILERA web site.

Nonprofit Organization
A nonprofit organization (NPO) or non-profit organisation, also known as a non-business entity, not-for-profit organization, or nonprofit institution, is a legal entity organized and operated for a collective, public or social benefit, in contrast with an entity that operates as a business aiming to generate a Profit (accounting), profit for its owners. A nonprofit is subject to the non-distribution constraint: any revenues that exceed expenses must be committed to the organization's purpose, not taken by private parties. An array of organizations are nonprofit, including some political organizations, schools, business associations, churches, social clubs, and consumer cooperatives. Nonprofit entities may seek approval from governments to be Tax exemption, tax-exempt, and some may also qualify to receive tax-deductible contributions, but an entity may incorporate as a nonprofit entity without securing tax-exempt status. Key aspects of nonprofits are accountability, trustworth ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Esperanto
Esperanto ( or ) is the world's most widely spoken constructed international auxiliary language. Created by the Warsaw-based ophthalmologist L. L. Zamenhof in 1887, it was intended to be a universal second language for international communication, or "the international language" (). Zamenhof first described the language in '' Dr. Esperanto's International Language'' (), which he published under the pseudonym . Early adopters of the language liked the name ''Esperanto'' and soon used it to describe his language. The word translates into English as "one who hopes". Within the range of constructed languages, Esperanto occupies a middle ground between "naturalistic" (imitating existing natural languages) and ''a'priori'' (where features are not based on existing languages). Esperanto's vocabulary, syntax and semantics derive predominantly from languages of the Indo-European group. The vocabulary derives primarily from Romance languages, with substantial contributions from Ge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Universal Esperanto Association
The Universal Esperanto Association ( eo, Universala Esperanto-Asocio, UEA), also known as the World Esperanto Association, is the largest international organization of Esperanto speakers, with 5501 individual members in 121 countries and 9215 through national associations (in 2015) and in official relations with the United Nations. In addition to individual members, 70 national Esperanto organizations are affiliated with UEA. Its current president is the professor Duncan Charters. The magazine ''Esperanto'' is the main organ used by UEA to inform its members about everything happening in the Esperanto community. The UEA was founded in 1908 by the Swiss journalist Hector Hodler and others and is now headquartered in Rotterdam, Netherlands. The organization has an office at the United Nations building in New York City. Structure and affiliated organizations According to its 1980 statutes (Statuto de UEA), the Universal Esperanto Association has two kinds of members: * individu ...

Single Sideband Modulation
In radio communications, single-sideband modulation (SSB) or single-sideband suppressed-carrier modulation (SSB-SC) is a type of modulation used to transmit information, such as an audio signal, by radio waves. A refinement of amplitude modulation, it uses transmitter power and bandwidth more efficiently. Amplitude modulation produces an output signal the bandwidth of which is twice the maximum frequency of the original baseband signal. Single-sideband modulation avoids this bandwidth increase, and the power wasted on a carrier, at the cost of increased device complexity and more difficult tuning at the receiver. Basic concept Radio transmitters work by mixing a radio frequency (RF) signal of a specific frequency, the carrier wave, with the audio signal to be broadcast. In AM transmitters this mixing usually takes place in the final RF amplifier (high level modulation). It is less common and much less efficient to do the mixing at low power and then amplify it in a linear ampl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Continuous Wave
A continuous wave or continuous waveform (CW) is an electromagnetic wave of constant amplitude and frequency, typically a sine wave, that for mathematical analysis is considered to be of infinite duration. It may refer to e.g. a laser or particle accelerator having a continuous output, as opposed to a pulsed output. Continuous wave is also the name given to an early method of radio transmission, in which a sinusoidal carrier wave is switched on and off. Information is carried in the varying duration of the on and off periods of the signal, for example by Morse code in early radio. In early wireless telegraphy radio transmission, CW waves were also known as "undamped waves", to distinguish this method from damped wave signals produced by earlier ''spark gap'' type transmitters. Radio Transmissions before CW Very early radio transmitters used a spark gap to produce radio-frequency oscillations in the transmitting antenna. The signals produced by these spark-gap transmitters c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
