"Decoding the Mystery: How Your Car Identifies Radio Songs"

Car radios now display song titles thanks to Radio Data System (RDS) or Radio Broadcast Data System (RBDS) in America, which sends data along with the FM radio signal. RDS transmits station IDs, program types, and song titles, allowing receivers to display this information. HD Radio, a digital and analog broadcasting technology, offers additional channels and data, including images. Gracenote, used in car head units, provides track information for Bluetooth streaming audio.

"Uncovering Discrimination in FM Radio Broadcasting"

An exploration of how FM discriminators work reveals the process of resolving frequency changes into amplitude changes for demodulation, using an old tube FM set as an example. The video simplifies the concept by redrawing the tube schematic with diode symbols, shedding light on the various methods of decoding FM and modulating carriers with information.

"Experience the Perseid Meteor Shower through Your FM Radio: A Unique Observing Opportunity"

You can track meteors by listening to them on your FM radio by finding a radio station transmitting from a city far enough from you. Meteors leave an ionized trail in the atmosphere that reflects FM radio signals. Radio observation allows for the detection of smaller particles than visual observations. While radio observation does not provide information on the direction of meteors, it can be done during cloudy nights or daylight hours. Different daytime meteor showers, such as the Arietids, Zeta Perseids, and Beta Taurids, can be observed using radio observation. The Perseid meteor shower, which peaks on the night of 13/14 August, is a favorite for many observers. Radio observations are best conducted overnight when human activity is low, and the number of detectable meteors increases after midnight. A step-by-step guide is provided for setting up and tuning into FM radio stations to listen to the Perseid meteor shower.
