AM Radio in Cars

The cluster debates the value of retaining AM radio in new cars for emergency broadcasts and reliability in remote areas like mountains, contrasting it with FM radio's better sound quality but shorter range, amid proposals to remove AM receivers.

Switch to AM radio and you'll have your answer.

This sounds regressive and pointless. FM/AM vs. FM radio has to be pennies. In some mountainous areas, only AM radio works.

What's wrong with offering an AM radio as an option, though?

this is about am radio going away, not fm.

That sounds super complicated compared to good old FM radio.

Well, your AM receiver wouldn't support them anyway.

In your country maybe but in others not so much and conflicting with the FM radio will kill this application there.AM radio isn't dead either despite being barely used. Good luck though.(By my own experience, the power consumption isn't that great for FM modulation, you want the frequency range, not the modulation)

AM radios ( in cars or not ) would be much more reliable than and mobile phone app OR using a PC

The problem is there are parts of the US where cell signals and FM cannot reach but AM comes through just fine. Particularly mountainous regions, where weather and safety reports are important. Telling people driving around these areas to keep a second radio running in their car seems kind of stupid when the functionality can be included in the head unit for pennies.Preserving AM radio is important for a few reasons that go beyond cars. AM broadcasts have exceptionally long range with relativ

AM sounds bad because it’s amplitude modulated. So variation in amplitude (i.e. signal strength) results in noise when decoding. FM however is not sensitive to this issue because its frequency modulated - slight variations in signal strength have no effect on the encoded signal.And yes, we can always upgrade the equipment. That’s what we did when we transitioned TV to digital signals and FM to digital FM - we reserved some bandwidth for over-the-air while freeing up the rest to be used for ot
