I remember going to the drive-in movie theater in the 80's. You had to tune your car radio to a specific frequency to hear the movie audio. If this device had existed back then, you wouldn't have needed to tune your car radio at all. I doubt the neighbors would have liked that though. As an aside, I remember being jealous of the neighbors because they got to watch all these movies for essentially free. The irony is that today, we're bombarded by content, it's become essentially free.
- imoverclocked 2y ago> you wouldn't have needed to tune your car radio at all You still need to tune it but there are many "center frequencies" that can be tuned instead of just one. So, you wouldn't have to tune far but you would still have to tune :) If you had a knob like most radios in the 80's it would save you from cranking the knob several times to get the dial into the right range before fine-tuning.
- jedberg 2y agoI think the theory is that every car that has an FM radio has it tuned to something. So no matter what, as soon as you put on the FM radio, it would have the audio.
- imoverclocked 2y agoYeah, until you have a 5 year old (probably me in this case in the 80s) that plays with random knobs on the dash when they get in the car. Is it volume? Is it the tuner? We’ll know once the car turns on!
- monktastic1 2y agoIt's broadcasting on every valid ("odd") frequency. I guess it still depends on if you have an analog or digital dial.
- badc0ffee 2y agoAn analog tuner with PLL would work much like a digital one.
- dylan604 2y ago> You had to tune your car radio to a specific frequency to hear the movie audio. This was great because it allowed for stereo. This also replaced the earlier idea of taking the speaker from the pole next to the driver's window, and then hanging from the window inside the car. This was just a mono speaker, but it was also right next to the driver's head. It reduced the drive-in's repair bills from people driving away before placing the speaker to its host stand (and other hooliganism) *just to add some color
