If you have one of those radios that show FM station call signs right on the display panel, then you have what's called the radio data system feature with your radio. The Radio Data System or RDS, is available in many US cities. There's a similar system in Europe as well.
In the United States, each FM radio station is allocated two herds of bandwidth. So if a radio station is at ninety three point one on the FM dial, its frequency is ninety three point one million herds, and it has between ninety three point one and ninety three point three million hurts as its allocation. The station doesn't fill all that bandwidth with music there's some space left over on both sides. RDS is a completely separate radio signal
that fits between the station's frequency allocation. It's like there are actually two radio stations broadcasting. One has music and the other has data. The RDS signal carries digital information with a data rate of about eleven hundred bits per second. RDS transmits data simultaneously with a standard FM radio broadcast. Your radio picks up the music and sends it to the speakers, and then it separately picks up the data
signal and sends that data to the display. Possible uses include transmitting song titles, station call signs, and signaling when traffic and weather reports are being broadcast. For more on this and thousands of other topics, is it how stuff works dot com Jack Threads is the online shopping destination for dudes.
