The FM broadcast band in Japan uses 76 to 95 MHz, and in Brazil, 76 to 108 MHz. The International Radio and Television Organisation (OIRT) band in Eastern Europe is from 65.9 to 74.0 MHz, although these countries now primarily use the 87.5 to 108 MHz band, as in the case of Russia. Some other countries have already discontinued the OIRT band ...
A broadcast translator is a low-powered (maximum of 250 watts) FM radio station that retransmits the programming of a parent station that operates on a different frequency. . Translators are not allowed to originate programming, and were originally designed to extend the coverage area of a primary analog FM stati
FM broadcasting started in Australian capital cities in 1947 on an "experimental" basis, using a (monaural) ABC national network feed, consisting largely of classical music and Parliament, as a programme source. [1] FM receivers were expensive and the audience consisted largely of hi-fi enthusiasts.
