Radio broadcasting requires various types of radio frequency (RF) equipment to do the job right. Remote pickup units (RPU) send program material from a remote location to the broadcast station using specialized high fidelity audio equipment. Studio-transmitter links (STL) send audio data from the station’s broadcast studio to a transmitter in another location. This is usually necessary because of discrepancies in where the signal originates and where it needs to be broadcasted. A radio data system (RDS) is a communications protocol standard which embeds digital information in FM radio broadcasts, providing information such as time, station and program information such as song and artist names. Lastly, broadcasting transmitters and exciters are at the heart of a radio broadcasting, performing core functions that bring the programming to consumers.
