This is the Radio subforum of the Entertainment forum, which means the topic for this forum is radio
broadcasting. There are many other uses for radio signals which are not broadcasting, such as amateur radio and radio scanners. Although those forms of radio can be very entertaining, they are not specifically
entertainment. To avoid overlap with the
Hobbies and Recreation forum at City-Data, discussion of those types of non-broadcast radio will be off-topic in this forum. (A few threads from that forum and a few threads from
Self-Sufficiency and Preparedness which discussed radio broadcasting were moved into this forum today.)
If you have questions about whether something related to radio is on topic for this forum, feel free to send me a Direct Message to ask.
