The only remaining station to launch with RCA 10 kW Ampliphase transmitters was Radio 270 from 4th June 1966, on-air some three months later than originally planned.

A Brief History of Radio Broadcasting in Africa
A Brief History of Radio Broadcasting in Africa Radio is by far the dominant and most important mass medium in Africa. Its flexibility, low cost, and oral character meet Africa's situation very well. Yet radio is less developed in Africa than it is anywhere else. There are relatively few radio stations in each of Africa's 53 nations and fewer radio sets per head of population than anywhere else in the world. Radio remains the top medium in terms of the number of people that it reaches. Even though television has shown considerable growth (especially in the 1990s) and despite a widespread liberalization of the press over the same period, radio still outstrips both television and the press in reaching most people on the continent. The main exceptions to this ate in the far south, in South Africa, where television and the press are both very strong, and in the Arab north, where television is now the dominant medium. South of the Sahara and north of the Limpopo River, radio remains dominant at the start of the 21St century. The internet is developing fast, mainly in urban areas, but its growth is slowed considerably by the very low level of development of telephone systems. There is much variation between African countries in access to and use of radio. The weekly reach of radio ranges from about 50 percent of adults in the poorer countries to virtually everyone in the more developed ones. But even in some poor countries the reach of radio can be very high. In Tanzania, for example, nearly nine out of ten adults listen to radio in an average week. -

INTERFERENCE FROM RADIO TRANSMITTERS A Guide for Radio Operators This brochure is primarily for amateur and General Radio Service (GRS, commonly known as CB) radio operators. It provides basic information to help you install and maintain your station so you get the best performance and the most enjoyment from it. You will learn how to identify the causes of radio interference in nearby electronic equipment, and how to fix the problem. What type of equipment can be affected by radio interference? Both radio and non-radio devices can be adversely affected by radio signals. Radio devices include AM and FM radios, televisions, cordless telephones and wireless intercoms. Non-radio electronic equipment includes stereo audio systems, wired telephones and regular wired intercoms. All of this equipment can be disturbed by radio signals. What can cause radio interference? Interference usually occurs when radio transmitters and electronic equipment are operated within close range of each other. Interference is caused by: ■ incorrectly installed radio transmitting equipment; ■ an intense radio signal from a nearby transmitter; ■ unwanted signals (called spurious radiation) generated by the transmitting equipment; and ■ not enough shielding or filtering in the electronic equipment to prevent it from picking up unwanted signals. What can you do? 1. -

It explains in some detail the advantages gained by radio broadcasters introducing the DRM ® Digital Radio Mondiale™ technology and some of the technical and commercial considerations they need to take into account in formulating a strategy for its introduction. The guide is a development of the previous ‘Broadcast User Guide’ and includes information on latest system and regulatory aspects for the introduction of the various DRM system variants. It also includes links to reports and articles on an extensive range of highly successful real-life trials. Digital Radio Mondiale (DRM) is the universal, openly standardised digital broadcasting system for all broadcasting frequencies up to 300 MHz, including the AM bands (LF, MF, HF) and VHF bands I, II (FM band) and III. -
