This is a No win topic, Because your opinion of Am is just that opinion.Not the best link. A good case of "if it's on the web it is so." The reference to bandwidth is wrong. AM is allowed an overall 10khz (NRSC rules) plus occasional overshoots for "averaged" measurement. Part 15 AM's are not required to do this, (low power AM's, unlicensed, only the licensed ones.)
Also, the "cost by comparison....." "Cheaper?" Transmitters are transmitters. Electricity is Electricity. FM has expensive antennas on towers. AM has NO expensive antennas, JUST towers, but a grounding system. Nothing is 'stored' in an AM or FM signal, either. Embedded? perhaps, as part of the signal is divided to carry information OTHER than the audio on BOTH AM and FM. (as in HD on EITHER.)
I've paid $16k for NEW top of the line FM transmitters, and $45k for others. Depends on your needs, power output, features, brand, even manufacturer's location...not necessarily the AM vs. FM argument. .
Coverage for either AM or FM is dependent upon POWER output, and a combination of terrain, antenna, even processing. AM travels terrain better, but it's not got a "get out of jail free" for coverage vs. FM.
There's enough wrong there to put any broadcaster in orbit. Some good info, some total, well....
Does your car have an AM and FM antenna?I though AM and FM used different antennas.
1) Try listening to a good (AM) broadcaster for potential sound.
2) As a nearly 30 year radio veteran and combined 17 year owner, I know how it works. I live it every day on BOTH bands, and still put out a helluva product on AM.
3) People who spread DISinformation about broadcasting on the web do a GREAT industry a DIS-service, and that's exactly what you're doing to my industry.
4) Well done, AM can serve and sound just as good. If you would like, I can also comb the web for "facts." (notice the quotes.) Truth is, there are FM's out there with less quality than what you'll hear coming from my AM towers, and those of many other GOOD AM broadcasters! Again, you refer only to the "bad" side of your experiences, because you cannot speak to the "good" side and potential in a first-hand basis. Many good stations prove great sound and coverage every day, 24/7 from hard work and attention to detail including upkeep!
5) "If it was it would be no doubt a widely used band today, and they wouldn't needed to develop FM." Note the attachment. Wide use? Of commercial stations (meaning non-hobby REAL broadcasters) there's only 1671 more FM's than AM's out of a total the FCC counts at 14,355. I'd say we're pretty widely used/utilized.
6) AM is doing well and YOU should listen to a good one now and then. (sparring back at the "you should watch" comment.)
I know 'boards are for opinions, but it helps if the information presented has some degree of credibility in fact.

Technology changes but the laws of Physics stays the same.Shame on you for bringing the laws of physics into a religious discussion.
It's a Fact that AM RADIO will never be as good audio quality as FM Radio.
You can Google that until you are blue in the face and you will NOT find anything to disprove it.
You just proved me Right.
You are wrong. I found something to disprove it. CLICK HERE.
Now with that proven, the real issue here is with the majority of owners and operators don't want the invest in the equipment or spend the time constantly tweaking their equipment to get the best sound out of it possible. For them as long as they are getting their billable ad time sold then its all good.
I have been in many... many radio stations where the owners and management could not give a rats ass of what the programming was that was playing on their station as they told me point blank they are not in the business of selling music, they are in the business of selling ad time... anything that runs between the ads to them is filler.
This unfortunately is the norm and one of the big reasons why AM radio is failing. Under the correct control and operation it can be a positive community experience where listeners are entertained and informed and keep tuning back in. Its no secret that by using the radio is the best was for companies to get their message out there. More people listen to the radio every day then watch tv and read the newspaper.
AM is almost dead because of the boneheads that are beancounters and not radio guys. AM could be a much bigger success if the owners allowed to invest in the technology and spend properly to maintain to keep the sound great. But now its rare to have a radio station with its own engineer. In fact ts quite normal for a stations engineer to work on 10 stations in three different states.
To me those are the issues
I remember taking apart AM/FM radios in high school. Sometimes as part of a school project!Does your car have an AM and FM antenna?
They may use a different ones at the Radio stations.
But I'm fairly confident your radio does the tuning.
Yep, it is a Carver TX-11a as I recall but if not the B or C models which are similar. The TX-11b even being AMAX compliant with optional de emphasis for the curve used by many AM stations. It is what the FCC and NRSC call a "modified 75 uS curve" but in reality it closely resembles the European 50 uS FM curve. I first heard a recording from this tuner back in 2001 picking up WMNI 920 from Columbus Ohio in full stereo and playing one of those mid 1960s songs with very wide stereo separation. As someone who was used to poor quality AM and just then beginning to hear AM stereo for the first time I was blown away at the quality. It sounded very close to what I expected from FM at that time.Umm that IS a radio broadcast... not a feed from the board.

the "A" we use does have switchable AM de-emphasis and wide/narrow selections! It also contains a gain switch on the front. GREAT description of the Carver and it's capabilities in your post, by the way! As a mater of fact, the AMAX name is kind of a "downer" to a Carver. AMAX receivers which were branded with the NAB logo and sold by Denon offered a stock 7.5khz AM stereo bandwidth promised. Meanwhile, a well-maintained Carver will easily produce the 10khz needed for GREAT sound! Enjoyed your post and thanks for chiming in! It's fun presenting AM in it's best light through a receiver being used for the actual streaming source. Doing this brings us many communications from all over the world, and helps disbelievers to think a second time about AM's potential. Many of the comments we get by the way are here:
