Information:  - A subcarrier is a sideband of a radio frequency carrier wave, which is modulated to send additional information. Examples include the provision of colour in a black and white television system or the provision of stereo in a monophonic radio broadcast. There is no physical difference between a carrier and a subcarrier; the "sub" implies that it has been derived from a carrier, which has been amplitude modulated by a steady signal and has a constant frequency relation to it.  - A radio reading service or reading service for the blind is a service of many universities, community groups and public radio stations, where a narrator reads books, newspapers and magazines aloud for the benefit of the blind and vision-impaired. It is most often carried on a subcarrier, with radio receivers permanently tuned to a given station in the area, or an HD Radio subchannel of the offering station. Some reading services use alternative methods for reaching their audiences, including broadcasting over SAP, streaming Internet radio, cable TV, or even terrestrial TV.  - 6RPH Vision Australia Radio broadcasts on 990 kHz AM and was previously owned and operated by the Foundation for Information Radio of Western Australia Inc. It now broadcasts Vision Australia Radio and aims to provide access to printed information for Western Australians with a print disability . Vision Australia Radio is a member of RPH Australia . Its radio reading service is available on 990 AM throughout the wider Perth metropolitan area . However , in the early part of 2015 the station started to play a recorded music loop , together with a repeated announcement that its service had been suspended due to `` technical issues '' . In March / early April 2015 , 6RPH ceased broadcasting , but has since recommenced transmission with the Vision Australia Radio service on 990AM and on IRIS digital . Radio 6PM occupied the 990 kHz frequency until the late 1980s .  - HD Radio is a trademarked term for iBiquity's in-band on-channel (IBOC) digital radio technology used by AM and FM radio stations to transmit audio and data by using a digital signal embedded on-frequency immediately above and below a station's standard analog signal, providing the means to listen to the same program in either HD (digital radio with less noise) or as a standard broadcast (analog radio with standard sound quality). The HD format also provides the means for a single radio station to simultaneously broadcast one or more different programs in addition to the program being transmitted on the radio station's analog channel.  - A magazine is a publication, usually a periodical publication, which is printed or electronically published (sometimes referred to as an online magazine). Magazines are generally published on a regular schedule and contain a variety of content. They are generally financed by advertising, by a purchase price, by prepaid subscriptions, or a combination of the three.At its root, the word "magazine" refers to a collection or storage location. In the case of written publication, it is a collection of written articles. This explains why magazine publications share the word root with gunpowder magazines, artillery magazines, firearms magazines, and, in French, retail stores such as department stores.  - A newspaper is a serial publication containing news about current events, other informative articles (listed below) about politics, sports, arts, and so on, and advertising. A newspaper is usually, but not exclusively, printed on relatively inexpensive, low-grade paper such as newsprint. The journalism organizations that publish newspapers are themselves often metonymically called newspapers. As of 2017, most newspapers are now published online as well as in print. The online versions are called online newspapers or news websites. Newspapers are typically published daily or weekly. News magazines are also weekly, but they have a magazine format. General-interest newspapers typically publish news articles and feature articles on national and international news as well as local news. The news includes political events and personalities, business and finance, crime, weather, and natural disasters; health and medicine, science, and computers and technology; sports; and entertainment, society, food and cooking, clothing and home fashion, and the arts.   - Radio is the technology of using radio waves to carry information, such as sound, by systematically modulating properties of electromagnetic energy waves transmitted through space, such as their amplitude, frequency, phase, or pulse width. When radio waves strike an electrical conductor, the oscillating fields induce an alternating current in the conductor. The information in the waves can be extracted and transformed back into its original form.
