![]() "Tony Meloche" wrote in message ... Horse hockey. I'm not saying Leonard's suit didn't hamper the reality of AM stereo, but if it had become a mainstream thing, "stereo lo-fi" would have never held it's own against "stereo hi-fi" (FM). Especially when the FM stations went to virtually ALL types of programming during the seventies. Prior to that, FM was classical, alternative (including what was known as "AOR") and as a vanguard, country. Nobody loves good old AM radio like I do, but there is no accident to the fact that AM radio today is very largely 24 hour news, sports, and talk radio formats. That had a whole lot more to do with changing technology than it did with Leonard Kahn. Classical music will always sound tremendously better on FM than AM because of the frequency bandwith. Classical music (as one example) in AM stereo will sound like stereo AM radio broadcast of classical music. A pale imitation of stereo FM broadcast of classical music. Tony There is absolutely no reason why AM stereo could not be just as high a fidelity as FM stereo, and in fact was in many cases. What gives AM broadcasting the characteristic 'telephone quality' sound it has is mostly the receiver. There is some pre-transmitter processing to limit the bandwidth used, but it doesn't need to be there for purposes of transmitting the signal, only for purposes of limiting said bandwidth. In Portland, we had several AMS stations with full frequency response (50-15K) just as FM. And AMS signals didn't degrade the way FM does when in the downtown area or on the 'dark side' of hills. Admittedly, AM signals can be noisier than FM on the fringes, but they are better in hilly terrain for the most part than FM. |

Regarding audio for computers,pick up a PC Magazine www.pcmag.com I
subscribe to the snail mail issues of that magazine and also Smart Computing magazine. www.smartcomputing.com (I have the magazine right here on the end table by my couch) for April 26,2005.Bill Machrone has a good article on page 45 in the magazine about audio for computers and he provides a website in the magazine to check out. http://machrone.home.comcast.net/pla...distortion.htm Comcast originated right here in Jackson,Mississippi.I bet y'all didn't know that.Enjoy my webtv toy,you say? I do enjoy useing my webtv "toy" but it is not a toy.I can learn and do all of those computer thingys you listed in your post,but the thing about that is,those thingys just do not interest me at all.Did I mention before I bought a new Velocity Micro,ProMagix tower computer last year from www.velocitymicro.com and I have broad band internet access? Do you think I am lieing about that? I never lie about anything.email me and I will forward information about my computer to you if you want to check it out.I bought my computer for $1,290.00 and I bought it for one thing and one thing only,World War Two gaming.My money and my computer and my decision. cuhulin |

The lack of fidelity has nothing at all to do with the mode of modulation, and everything to do with artificially restricting factors. |

That's the FCC's fault. There are too many stations and the bandwidths (both transmit and receive) have to be narrow or the splatter would drive the few remaining nut jobs that still listen to AM away. |

True enough - any "American Five" of the 1950's gave better AM performance than the AM tuner in any modern stereo receiver, for example. But the industry as a whole just didn't invest the time or effort in making AM as good a broadcast medium as FM, and there was certainly no consumer demand for it, either - or at least not enough to make a difference. When CD's came in, I was astonished at how quickly they swept away vinyl - even quicker than the most optimistic projections. The consumer market loved them, and that was that. AM stereo was one of those things that simply didn't "catch on", and as I said, largely (if not completely) because it was seen, understandably as "reinventing the wheel".

they swept away vinyl - As a matter of fact, when CDs came in, it was cassette tapes that they swept away. Cassettes had been out-selling LPs for several years before the arrival of CDs. AM stereo sounded as good as, or better than, your typical cassette tape, to my ears. There's no accounting for popular tastes! |

The average person can't tell the difference between a phone call and FM. |

CD's and DVD's can and often do get scratches.I see them all the time in
the thrift stores here.There are clear flexible plastic covers available at stores which sell electronics.I use them on my Scotch and Irish music CD's and my computer CD's. cuhulin |
