| Did you know that most FM stations also have 1 or 2 other AUDIO channels which you can NOT hear with ordinary FM radio. Yes it is correct, there are many other useful audio channels on FM band . Just buy one of these SCA receivers ,Tune to your favorite FM station, flip the switch and listen to what you have been missing so far . SCA stands for Subsidiary Communications Authorization. It is commonly referred to as "subcarrier", because a subcarrier is used to transmit the information. A definition of subcarrier is now in order: A subcarrier is another modulated signal transmitted with the baseband audio. Think of it as another transmission modulating the station's audio. By the way, this is how the stereo information is also transmitted. What types of information is transmitted using SCA? Many different types. Actually, there's no limit as to what can be transmitted. Here are some examples: Background music. This is probably the most common transmission found. Reading services. Also very common. Newspapers/books/etc are read for the visually impared, along with other information. Foreign language services. Music, news, etc in a variety of foreign languages, aimed at ethnic groups. Data transmissions. Stock market data, sports results, etc can be sent. This data is supposedly encoded in some way. Any details would be greatly useful to the monitoring community. |
