Sweden Calling DXers
Sweden Calling DXers was a radio program on Radio Sweden, founded in 1948 by Arne Skoog. He reasoned that shortwave listening or DXing was a very young hobby, and that by providing information in a weekly program for shortwave listeners about their hobby, Radio Sweden was teaching its own audience about how to listen better. While the first program was based solely on Arne's own listening, listeners were encouraged to write in with their own news, and soon virtually all of the program was based on listener's letters (an early example of interactivity). The program was aired on Tuesdays in all of Radio Sweden's services (i.e. languages) except Swedish. After Arne Skoog When Arne Skoog retired in connection with the program's 30th anniversary in 1978, the program was taken over by George Wood, a member of the Radio Sweden English Service. After a number of years, as media changed, it began to cover less about shortwave, and more about satellite radio and television. Later coverage ...

Radio Sweden
Radio is the technology of signaling and communicating using radio waves. Radio waves are electromagnetic waves of frequency between 30 hertz (Hz) and 300 gigahertz (GHz). They are generated by an electronic device called a transmitter connected to an antenna which radiates the waves, and received by another antenna connected to a radio receiver. Radio is very widely used in modern technology, in radio communication, radar, radio navigation, remote control, remote sensing, and other applications. In radio communication, used in radio and television broadcasting, cell phones, two-way radios, wireless networking, and satellite communication, among numerous other uses, radio waves are used to carry information across space from a transmitter to a receiver, by modulating the radio signal (impressing an information signal on the radio wave by varying some aspect of the wave) in the transmitter. In radar, used to locate and track objects like aircraft, ships, spacecraft and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shortwave Listening
Shortwave listening, or SWLing, is the hobby of listening to shortwave radio broadcasts located on frequencies between 1700 kHz and 30 MHz. Listeners range from casual users seeking international news and entertainment programming, to hobbyists immersed in the technical aspects of radio reception and collecting official confirmations (QSL cards) that document their reception of distant broadcasts ( DXing). In some developing countries, shortwave listening enables remote communities to obtain regional programming traditionally provided by local medium wave AM broadcasters. In 2002, the number of households that were capable of shortwave listening was estimated to be in the hundreds of millions. The practice of long-distance radio listening began in the 1920s when shortwave broadcasters were first established in the US and Europe. Audiences discovered that international programming was available on the shortwave bands of many consumer radio receivers, and a number of magazines an ...

DXing
DXing is the hobby of receiving and identifying distant radio or television signals, or making two-way radio contact with distant stations in amateur radio, citizens' band radio or other two-way radio communications. Many DXers also attempt to obtain written verifications of reception or contact, sometimes referred to as " QSLs" or "veries". The name of the hobby comes from DX, telegraphic shorthand for "distance" or "distant". The practice of DXing arose during the early days of radio broadcasting. Listeners would mail "reception reports" to radio broadcasting stations in hopes of getting a written acknowledgement or a QSL card that served to officially verify they had heard a distant station. Collecting these cards became popular with radio listeners in the 1920s and 1930s, and reception reports were often used by early broadcasters to gauge the effectiveness of their transmissions. Although international shortwave broadcasts are on the decline, DXing remains popular among de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Satellite Radio
Satellite radio is defined by the International Telecommunication Union (ITU)'s ITU Radio Regulations (RR) as a ''broadcasting-satellite service''. The satellite's signals are broadcast nationwide, across a much wider geographical area than terrestrial radio stations, and the service is primarily intended for the occupants of motor vehicles. It is available by subscription, mostly commercial free, and offers subscribers more stations and a wider variety of programming options than terrestrial radio. Satellite radio technology was inducted into the Space Foundation Space Technology Hall of Fame in 2002. Satellite radio uses the 2.3 GHz S band in North America for nationwide digital radio broadcasting. In other parts of the world, satellite radio uses the 1.4 GHz L band allocated for DAB. History and overview The first satellite radio broadcasts occurred in Africa and the Middle East in 1999. The first US broadcasts were in 2001 followed by Japan in 2004 and Canada in 2 ...

Internet
The Internet (or internet) is the global system of interconnected computer networks that uses the Internet protocol suite (TCP/IP) to communicate between networks and devices. It is a '' network of networks'' that consists of private, public, academic, business, and government networks of local to global scope, linked by a broad array of electronic, wireless, and optical networking technologies. The Internet carries a vast range of information resources and services, such as the inter-linked hypertext documents and applications of the World Wide Web (WWW), electronic mail, telephony, and file sharing. The origins of the Internet date back to the development of packet switching and research commissioned by the United States Department of Defense in the 1960s to enable time-sharing of computers. The primary precursor network, the ARPANET, initially served as a backbone for interconnection of regional academic and military networks in the 1970s to enable resource shari ...

FUNET
FUNET is the Finnish University and Research Network, a backbone network providing Internet connections for Finnish universities and polytechnics as well as other research facilities. It is governed by the state-owned CSC – IT Center for Science Ltd. The FUNET project started in December 1983 and soon gained international connectivity via EARN with DECnet as the dominant protocol. FUNET was connected to the greater Internet through NORDUnet in 1988. The FUNET FTP service went online in 1990, hosting the first versions of Linux in 1991. The main backbone connections have gradually been upgraded to optical fiber since 2008. First 100 Gbit/s connections were put in production in 2015. FUNET is connected to other research networks through NORDUnet, and to other Finnish ISPs via three FICIX points.

SUNET
SUNET is the Swedish University Computer Network. SUNET provides high-speed Internet access to academic institutions in Sweden. The current incarnation of the network, Sunet C, provides 100 Gbit/s links between the cities hosting universities. It replaces the older network, OptoSunet, based mainly on 10 and 40 Gbit/s links. SUNET's upstream network is the Nordic NORDUnet. SUNET is governed by a board appointed by the Swedish Research Council (Vetenskapsrådet). In addition to the board there is a technical reference group and a development group, as well as people working at the participating universities. SUNET did operate one of Sweden's largest FTP archives, mirroring extensive useful material of 'academic' interest, similar to the UK Mirror Service hosted by the University of Kent. The service ftp.sunet.se is now hosted by Academic Computer Club at Umeå university. Before the service was down sized and domain was handed over to ACC, the service could handle more than 10,000 con ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
