The FM broadcast band, used for FM broadcast radio by radio stations, differs between different parts of the world.
In Europe, Australia and Africa, it spans from 88 to 108 megahertz (MHz) - also known as VHF Band II - while in the Americas it ranges from 88 to 108 MHz. The FM broadcast band in Japan uses 76 to 95 MHz. The International Radio and Television Organisation band in Eastern Europe is from 65.8 to 74.0 MHz, although these countries now primarily use the 88 to 108 MHz band, as in the case of Russia. Some other countries have already discontinued the OIRT band and have changed to the 88 to 108 MHz band.
If you want everyone to hear your broadcast, or at least as many people as possible, use the 88–108 MHz band, that's where all the commercially made, personal radio receivers work and all the commercial broadcast radios work.
