Reception of each station of either AM or FM
I realized that I came across a mix of voice from two radio station sometimes, while car is driven. But, that was happened at a certain location and could be depending on antenna and radio design.

Madness, not progress
Yes, we should care. One area I want for AM is the hometown radio station, so as to put me in touch with the local community at a speed I can take in and without my being shackled to the computer. The advantage is human, not technological, and provides me with an outlet to slow down, not speed up.

One aspect of engineering that's seemingly been forgotten is the consumer's mental well-being as it relates to what the various technologies can provide (and, for whatever reasons, many reports suggest that mental illness is on the rise). There's definite good for me in technology that provides light talk and nostalgic music, versus TV and computer networks specifically designed to bring me 24-by-7 news/information that more often than not needlessly rattles my brain and is out of my control anyway. I don't need the "future shock."

Beyond that, instant feedback often makes for knee-jerk reactions (this is potentially disastrous in the battlefield). Ironically, it also makes for "paralysis by analysis" decision making (because there's too much information). I want old technology and what it traditionally brings. I want advanced technology when I really need it, not just because it's there.

Re: Madness, not progress
@Vincent--I think college radio is also all but gone too.

One counterargument is that nearly anyone can set up an internet "station" and stream content to end consumers.  Once all cars are connected with always-on IP links, then IP-radio and IP-TV will dominate.

I'm not sure the above is true, but food for thought.

Re: Madness, not progress
@eafpres1---From what I see initially, there are surprisingly about 20 college stations still on the air here in New Jersey, although virtually all of them are FM (one is listed as an AM station that apparently has since gone to an Internet radio format). Locally, we have one very active college station and a commercial AM station only a few miles away, for which I'm grateful.

Again, I much prefer old technology on this one, more for what it implies about lifestyle than anything else. But as for how signals get to my car in future and how "gadget/service of the day" technology imposes itself, I'll call it a draw as long as I can access my hometown talk and music station through a device I know as my car radio.

But they do not do the same time as they are not substitutes. I do not understand the comparison. CD players are for recorded music while radio is mainly transmitted live from the stations. They are not substitutes.

What If The Internet Is Down
I personally listen to AM every day to/from work (talk shows).  With that being said, if the demise of over the air radio is already taking place in favor of other forms of entertainment (via satellite or cellular data), what will we do when those methods of communication are not available due to a hurricane, ice storm, censorship, or something equally as bad?  During a recent ice storm here in the northeast, power was lost for over a week, cell service went down, and cable was obviously not available.  Many people were in the dark - some without even flashlights or a battery powered radio.  However, some of those people who were not prepared did remember they had a battery powered radio - the one in their car.  A boatload of important information was broadcast via the radio stations to those who could listen.

That seems to be the paradigm as there are radios in most of the smarthphones and they work very well. The challenge for the industry is not the technology, it is just that it is competing with many other choices and alternatives.

Satellite radio
Syrius Satellite radio continues to grow in market share across the overall radio market including automobiles, mobile devices and residences. No commercials, large selection, transmission in remote areas of US while driving. Can't beat it and prices can be negotiated down to $5 per month. I never listen to AM any more like an increasing amount of the population. News talk shows are being phased out in lieu of sport radio which is being shifted to satellite and FM now.

The "All American Five"
I don't think any discussion of old AM woukd be complete without mentioning the "All American Five", A.C. / D.C. radio. Early attempt at eliminating the power transformer. The tube filiments were set up so the 5 in series worked directly from the house 117 mains. The 35W4 and the 50C5, etc. One side of the line went right to the chassis. Depending on which way the plug was in the wall, maybe neutral or maybe hot. If a knob fell off and you touched the shaft, you knew when it was the hot side to the chassis. They must have taken the UL guy out to a long lunch to get that past :.)

 

Bill, I see you refered to the "switch" in the old car radio power supply as the interrupter. Avoided the popular term that could have a different meaning today :.)

Re: Vibrators.... :-)
@Martin....there, I said it!!  I had a 6V VW when I was young, and one day someone gave me an old valve (tube) car radio, with a vibrator power supply, that worked on 6V.  The power supply was in a large box under the hood, and the radio bit was about the same size as a normal car radio (just heavier).  It worked well for about a year, then some @#$%&*% stole the part in the car, thinking it was standalone, leaving me with the now useless power supply.   But I'd like to have seen the @#$%&*%'s face when he tried to make his stolen bit work!

Hi Marty--good point, in the sense of high data rate.  On the other hand, the internet of things has lots of nodes but low data rates.  Using AM would be great for the ability to transmit almost from anywhere and get signal.

AM may be unable to offer much data piped because of the data rate. I know there is the advantage of wider coverage but it suffers from data capacity issue.

Re: Even more super-broad band?
I'm not certain I understand what you are asking, upgrade what? AM radio? Using this 1 MHz of spectrum for something else?

AM radio is not very HI-FI because there is only 10 KHz channel allocations. You loose a lot of the high end frequencies in music. That's why people listen to music on FM that has wider channels and more audio bandwidth for snare drums and cymbols. So AM became talk radio, don't need a lot of audio band width for that.

 

Unless you want to add DSP and transform coders and get more "fake" audio bandwidth out of it that way. But this would not be compatible with the billion AM receivers out there.

"These are difficult times for the commercial broadcast-radio business, both AM and FM. According to various articles, such as this one from The Los Angeles Times, listener ratings are continuing to fall, and some carmakers -- where most radio listening is done, apparently -- are considering eliminating radios in the car completely, and not even offering it as an available option"

Bill, software defined radios or internet radios had taken oven the traditional AM/FM radio. In mobiles also FM radios are wide  popular. What i understood is back end technologies are still in place for FM, only the receiver end equipments are changed.

@Myankalog: I agree with you on this. Internet Radio has taken over the traditional radio in a lot of places but that has only happened in places where the cost of highspeed internet has fallen down and it's available on the go. In countries where that's not the case and people are not able to afford highspeed internet on the go, the traditional radio is still popular and mainstream.

   Consider a AM station located somewhere in Srilanka and we can tune into a Mediumwave to Shortwave using a receiver in lakshadweep.

While driving I too use only FM, because of the clarity and lots of events.  But occasionally tune to AM when at home.

Another reason why I don't like listening to AM while driving is since the AM bands are so closely spaced there is spurious spillover casuing a lot of distortion.  The antenna needs to be still otherwise the signal reception and signal strength won't be good making it nonpleasurable while driving.

  I don't know how does this HD or digital radio work out while driving.

Tzubair, here the bandwidth cost/usage has to bone by the user. If network is an issue; they can use FM radios over basic model; which won't fetch you anything more than the mobile cell power.

Practically, every Android phone has FM Radio. Unless there is something I do not know, it works just as the one from the FM frequency. As people buy phones with these capabilities, radio will be like watch - devices that will fizzle one day irrespective of what we may think about them at the moment.

How do you define "better"? If you can hear the thing, does it matter how it is deliverred. I do not see how AM will be better than the web if sound quality is all that matters in this.

certain superior properties
Say what you want about the creaky old AM bad, but it offers long distance coverage at night, and you can build your own radio from as little as a length of wire, a coil you can make yourself, a capacitor (ditto if you put your mind to it), sensitive headphones, and a diode... that you can also make yourself!  "Come the revolution", a regional long term power outage, or perhaps the killer earthquake in which California breaks off and everything else sinks into the Atlantic, we will be totally thankful for AM when the internet is kaput and cell coverage is dead.

@EMCGenius,

I still remember the little glass Germanium diode, OA79 with a cap and a long wire which I run from the second floor of my building. I used to listen the local AM station witth a headphone. I think we should have community radios running AM just to keep the technology which served us well even during wars.

@EMCgenius: I think the technology that powers commercial AM radio is also being used by other areas like police, ambulance networks etc. I don't think that technology is going to fade away. What the blog refers to is the use of AM Radio technology for commercial broadcasting and whether there's a need for that or not. As far as other applications of AM Radio technology are concerned, they do make the AM radio superior and I think it's going to stay. The commercial use for broadcasting on consumer radio sets, that I'm not sure about.

In my part of the world, FM radio has already taken over and AM radio is on the verge of a natural death. There's only one AM radio station being broadcasted and the quality of the content is not so great anymore. Had it not been owned by the government, even that would have ended long time back as there's no money to be made on it.

In most parts of sub Saharan Africa, AM radio is still very popular because of BBC which broadcasts quality news to local people even in their local languages. The fidelity and extensive wide coverage of AM radio cannot be replaced in a hurry especially in the Arab world where radio is still dominate.

Fasmicro, you may be right about Africa and Arab world. But when it comes to developed nations like US and EU, the old small radios are fadeout a decade ago. Majority are using internet radios over smartphones and Ipads.

@Myanalog, In developing nations  Internet is not accessible by everyone because Internet cost is pretty high. So people here still prefer AM radio over internet radio.

Sure cost of Internet is a big issue in most countries and that continues to affect how consumers consume digital data. Yet, the trajectory points to the one where we will expect to see a lot of these nations moving to do things on the web as cost of bandwidth continues to drop.

The big problem may not be the means of communication but the programs. I am not sure there are a lot of exciting things on radio for people to be overly concerned. Except my car, I do not think I will care which radio station is out there.

That is not the case in U.S. There are hundreds of stations one can choose in some cities in U.S. The problem I have with radio is the fact that except I am in the car, I do not see any other place I need to listen to it.

There is no debate over that. And I think over time, the Arab world and Africa will follow the same curve. There are many analog things that will not survive this age of disruption.

But that does not change what the consumer hears. The big question is not the underlining technology but the program. I know that without BBC, most parts of Africa will drop their radios. BBC Radio service remains a very important product in radio across Western and Central Africa

@fasmicro: That's true. Even in the rural part of my country, AM radio continues to exist and serve as a means for people to stay informed. The long range of coverage for AM network is certainly a big advantage when it comes to places like these where it may not be worthwhile to set up a large number of boosters.

You can argue that as countries become richer, they do away with radio. I am just thinking about this as most of the places where there are radios are largely developing nations.

Ue2014, you can connect your phone to the car info systems through audio Line-in cables. This can provide you a stereo or Dolby effect based on the type of speaker systems installed within your vehicle.

But many I.have seen here is comfortable with devices like pen drives and CD's as they use their phone even while driving for calls and sms. But I take your point, yes, it could be used as such too.

Ue2014, from USB and other devices you can replay only the stored music/videos. But if you jack your Smartphone, you can play FM radios  in live mode.

Re: Smartphones Vs Stereo
Yes....I agree. It depends on individual favor also sometimes. FM Radio's will allow you to be updated to date and provide you with a variety of programs including jokes, discussions etc. If anyone interested in the same, they would refer FM Radio's. On the other hand, USB like devices allows you to enjoy preferred selection of songs uninterrupted. Also if you are to use your phone for both music and calls/ sms purposes, it believe that could be little disturb.

Ue2014, you are right. Both have its own merit and demerit. One is lively in dynamic nature and the other one is passive but have the choice of selection.

Re: Internet radio
I had the Lucent Technologies worldwide account when I was at Burr-Brown and then TI as Corporate Account Manager/Field Apps Engineer.

I remember, in 2002, when Lucent Digital Radio system, in Warren, NJ (Right across the street from the TI NJ office), started out and used In-Band On-Channel (IBOC) technology which was designed to allow broadcasters to convert to an all-digital AM or FM broadcast system. The company planned that its digital radio would let listeners hear crystal-clear audio, while also providing new data services over regular broadcast signals. Lucent said that listeners would be able to hear IBOC, satellite, or Internet audio over the same receiver--whether in their car or at home--with wide varieties of programming and interactive services.

I frequently visited their NJ facility and worked with their designers to help incorporate TI solutions. Bell Labs in Murray Hill, NJ had a large satellite dish that supported this development as well at the time.
