Congress moves to preserve AM radio in cars
- josephcsible 3y agoWhy can't the government just use FM for emergency broadcasts?
- kelseyfrog 3y agoFM is a 90-year old technology. You can't expect the government to be at the cutting edge of things.
- op00to 3y agoYou can build an AM radio out of 4 resistors, 3 capacitors, a couple transistors that are present in most electronics and easily cut out, and a coil of wire. If you have a crystal, you might not even need a voltage source! I just looked it up, and there are FM circuits with similar component counts, so I guess I have no idea what I'm talking about! :)
- zamadatix 3y agoAM signal travels much farther and you, technically, don't need local power to listen to it. In cars the latter isn't really true though. If those aspects are the concern it would seem to make more sense to give everyone one emergency set rather than require every car to implement it.
- Jeema101 3y agoThey could but AM signals have a much larger range compared to FM. FM is mostly line-of-sight - AM signals aren't because they get bounced off the upper atmosphere back to the ground.

- indrora 3y agoBecause AM is frustratingly simple.
- PaulHoule 3y ago... if there is no AM radio where will people tune into right-wing talk?

- asdefghyk 3y agoAM radios ( in cars or not ) would be much more reliable than and mobile phone app OR using a PC
- Hippocrates 3y agoThe last time I heard AM radio was 25 years ago in my dads ~1990 civic hatch. The fact that some 50mm people still listen to it is mind blowing. Couldn’t one purchase a standalone AM radio for 10 bucks these days? Not everyone has a car anyway.
- sourcecodeplz 3y agoYou don't even need electricity to listen to some AM signals. It really is essential for emergencies.
