    AM radio stations really killed AM radio. Prior to the 1990s, on an AM/FM combo, the AM station was typically a "full service", 24 hour live format and the FM many times was automated music...
    In the 1990s, most AM stations seem to make the shift from being local, "full service" to 24/7 nationally syndicated talk radio (large corporations taking over local radio as part of the 1996 Communications Act, likely play into that also), and those stations no longer were the community information hubs they once were.
    As far as sound quality, 10 Khz channels with CQUAM Stereo sounded really good on a receiver that had an equally wide bandwidth...But broadcasters and receiver manufacturers went narrower band and dropped the C-QUAM...
    Now broadcasting corporations just see AM radio licenses as a backdoor to "commercial LPFM" operation.
    The FCC is also to blame for not strictly enforcing Part 15 noise limits on consumer devices.
    No reason the equipment inside a Tesla can't be filtered to reduce RFI. The traditional internal combustion engine literally has spark gap transmitters firing thousands of times a second, and they are filtered to reduce RFI. If you look at a lot of retro computers, they have extensive RF shielding around them and small capacitors on lines for RF shunting, now you rarely see that, mostly as cost reduction measures (ok, the RF shunt capacitors are no longer there because data lines are shifting at UHF/SHF speeds) ..

      What you are describing would go against Tesla’ s, and most other Web 3.0 disruption based companies design tenants .. which is to push off that cost onto everyone else .. Tesla could build RF emission shielding into their cars, but won’t,. And if they were pushed they’d just say that everybody else needs to design more selective tuners.
      It’s basically what happened with Light Squares and their interference with GPS signals a decade ago .. they wanted to run LTE on their purchased frequencies, regardless of the fact that consumer GPS receivers would be jammed while in proximity .. the company pushed it off on everybody else to redesign their RF front end

    In Norway, AM has been dead for 40 years at least. FM has been dead for around 10 years, because DAB was supposed to be so much better. I don't listen to radio anymore because of it. I got tired of losing signal everywhere for no apparent reason. Some of the point of maintaining the FM radio here in Norway was to make sure there was as much coverage as possible, for emergency broadcasts EVERYONE (Insert Gary Oldman gif here :) ) could receive. Now, we have spotty coverage, and instead of having a bad but intelligible signal, we have perfect clarity or nothing at all. The excuse was that we were running out of frequencies on the FM, but... we're 7 mill. people and a handful or radio stations... I miss the local FM stations, and I wish we had AM as well. So I listen to radio on the interwebs, and get my FM/AM fix on CB.

It was amazing to be directly under an EL track and still not have a ton of noise blasting through it. Not only was the car quiet of noise that allowed me to install a HF Ham Radio in it, they put a good quality radio in the car, too. My Hyundai hybrid I have now is very noisy, however their AM analog and HD radio do work fine in it. It does pick up some noise, but not enough to interfere with even a weak station that I wouldn’t listen to very long anyway. The cars that have eliminated the AM radios in them beg the need to be measured to see if they are FCC compliant. I have noted that vehicles beside or near me at stop lights are a source for noise. The same for signage and other lighting. The less we deal with that, the more trouble we’re going to have as time goes.

    AM is not dead. The advent of digital AM radio has saved the band. It sounds as clear as braodcast FM and when you fall out of the digital range, the radio automatically drops back to conventional AM. AM is also many nation's default national emergency communication band because of its extreme range. It requires no networks to get the long range, unlike internet, cellular, and VHF/UHF communication. The aspects of AM broadcast radio being excellent for national emergency communication will likely keep AM broadcast alive a long time. International shortwave broadcasts are still done in AM with some SSB. The infamous citizen's band is mostly AM as well, which is also an excellent communication resource when networks are down. Aircraft communication is all AM ,from the air, because strong FM signals will drown out all distant and weaker FM signals, AM does not do that the same way. Some Satellite communication is done in AM as well. AM receivers are almost childishly easy to make, as well. I think AM may be around a long time. As for Tesla Motors, electric cars are only good for cities and near suburban areas. The battery range, charging time, charging station availability, and lack of portably storage ability, assures electric cars will not be used in far suburban, and rural areas.

    During a natural disaster with power out, the broadband RF hash that usually makes AM inferior disappears as all the noisy LED’s, PV panels and switch-mode power supplies stop working. Thus, the signal-to-noise ratio of AM increases. Even just one high power AM transmitter could be heard across an entire continent at night. AM is inferior most of the time but far superior and necessary for those rare events, when cell towers and internet goes down.
    I remember as a kid going on a road trip through the country. As blue sky gave way to grey clouds, you could hear faint static crashes listening to the local AM station - an early warning of thunderstorms. This was a time before smart phones and weather apps. And a portable/pocket AM radio with a ferrite bar can be rotated to find max signal strength for direction-finding (DF) - the same principle aircraft use as a navaid for NDB’s. It’s not just about content - AM can be used to predict weather, propagation and for navigation! It’s still incredibly useful for multiple reasons!

    AM radio was the very original radio system that has existed since the early part of the 20th century. One of the reasons that it still exists today is that no one wants the band of radio frequencies that the FCC assigned to AM radio a long time ago. Today it seems like AM is mostly used for talk radio and a few news stations. Also AM radio is still used for highway information. However since Edwin Howard Armstrong invented FM radio, FM radio has always had better sound quality since it is not subject to electrical interference. Also the truth is that electric car makers can do things that will reduce AM radio interference, however since that would cost extra money they are not likely to do it. One thing that was used for many years in cars to reduce AM radio interference was radio signal suppression spark plug wires.

    In the UK they retain (broadcast band) AM in addition to (VHF) FM and digital broadcasting. But since the 1920s there is a broadcast service on *Long Wave* (198 kHz) below the broadcast band. This requires a high transmitter power and a gigantic transmitter antenna. Long Wave propagation is different to that on the broadcast band. It is almost entirely by "ground wave" and there is very little "sky wave". This means that reception is constant, day and night.
    The advantage is that reception of the BBC (Radio 4) on Long Wave covers most of the country from a single transmitter. I reckon I could drive from Scotland to Spain and listen to the BBC most of the way without re-tuning.

Car stereos and cell phones from the last 3 years already cover the whole 76 to 108MHz band.

    I would say that AM radio is not dead, but it is terminal. Preserving it is an exercise in futility. That is not a bad thing. It is simply a technology who's time has past. That said, it is used for some pretty critical things. So what we need to be doing is asking the following question. What is going to replace it? For each use case, especially the critical infrastructure ones, we need to be working towards a new technology that not only replaces it, but improves upon it, even if this technology does not exist yet. We need to actively be working on the next thing that will check every single box that AM Radio checked, while also improving on some of the classic problems with the technology. Like your dad mentioned Amplitude Modulation lends itself to allot of interference due to how easily any kind of noise can affect the amplitude of the carrier signal. So as an example, interference is one of the issues the replacement should at least address if not fix.

DAB was supposed ro be the standard in Canada for digital radio, but being so integrated with the US, especially the auto industry, DAB lost out to FM HD Radio, but there's very few stations that support it, and even fewer that use multiple channels. Yes, I could use the RadioPlayer Canada (90% of Canadian radio stations), Tunein Radio, iHeartRadio Canada, and a host of other apps to stream AM, but why waste (albeit audio streaming likely wouldnt be a lot) my data?

    Elon Musk can bite me. AM provides unique programming that can't be found with other broadcast systems. It's also crucial to small towns and cities for local news and information.

    Damn hearing that bit about most AM radios not having a good decoder being part of botching the sound now I really wanna hear what a quality AM radio can do....

      Find a working McKay-Dymek AM Tuner, and connect it to a really good antenna (such as the accompanying rod antenna) , or a Wellbrook loop). You'll be pleasantly surprised.

    Here in Tucson I worked at five AM stations. Did you know that All Ford cars for 2024 will not have AM. You already know about the electric cars. You would think that the FCC would have something to say about the RFI interference. In the 50s my parents has a table lamp with a lot of coat hangar type of wire as the base and it always during the day picked up a local AM station not very loud but if you sat with in two feet you could hear it. We still have a AM station that transmits in stereo.

    I've been fiddling around AM radios for a good part of my life. Now I have more knowledge on how to get better reception, but it's sad to find fewer stations than I used to.
