The problem with AM radio as a technology today is not fidelity. It's interference. Horrible, intolerable interference.
It's only a fidelity problem with stations voluntarily cut their bandwidth down to nothing, or worse, throw IBOC into the mix. While it'll never be fully on-par with FM, the sound quality of a well-processed AM signal-- even on an el cheapo dollar-store radio isn't all that bad. A spoken-word format on a decent-sounding station (like 990 here in Philadelphia, or 950 at night when IBOC's off) is fine if there's no interference. Stations like the CBS-owned ones sound absolutely fatiguing to me; it's as though every host sounds like a caller. But even that is only 1% of the problem.
I live in the heart of the Philadelphia market, on the second-most-traveled road in town. The entire AM band, save KYW and a few others, is pretty much inaudible within a half-mile of my home. Interference from everything-- the new LED traffic signals, street lights, power lines, and my own car's engine-- render stations like WIP and WPHT useless. Again, I'm not a "fringe signal" listener. I'm in the absolute target of those stations-- gender, age, income, and geographically. I can't listen. And these are the SUCCESSFUL stations on the band.
I stream out-of-town outlets (WAEB, WPGB Pittsburgh, 1200 in Boston, etc.) to hear basic syndicated programs that I can't hear in my home or office because 50,000-watt WPHT cannot overcome interference from the computers, modem, DVR units, etc. I also know whenever the refrigerator or air conditioner compressors kick in if I'm trying to listen to a Phillies game (I'm one of those who turn down the TV sound because I like Franzke and Andersen).
The radio geeks are so out of touch with this it's scary. Whenever I bring this up, I get a handful of E-mails from well-intentioned folks offering "simple tips" like using only battery-operated radios, re-arranging the room so not to have the computers nearby, ordering the $50.00 Selectenna, having a professional rip my car apart and re-shield the cables to the head unit in the dash, and my personal favorite-- move to a more remote area.
I'm a radio guy and I won't even do stuff like that. You think anyone under the age of 30 today will? Much less a female?
I spent the majority of my life as a DXer, listening to hours of faint, fading signals. I cannot even tolerate the offensive interference anymore. My wife (and everyone else) becomes downright upset when I drive around trying to listen to a program on AM because of the obnoxious noise. Can I blame her?
There are a few hosts I like to listen to on WIP when driving around-- but instead I'll often listen to 97.5 just because it's crystal-clear even when those hosts I like are on 610. Again, it's all about the interference. (Though WIP's fidelity makes a 16k dial-up stream sound good.)
The radio geek hears me complain about AM sound and immediately assumes "fidelity." I say interference. The geek then assumes I mean "from other stations" and often goes into a rant about how the FCC "sucks because they licensed too many stations." It's all hogwash. There has never been a problem with too many stations. We're living in a 500-channel world. Too many stations would actually be a good thing. The problem is man-made interference. And it's never going to get better; it's getting worse by the day as more and more items contain processors.
America's entire lot of AM stations could be [gradually] moved to Channels 5 and 6. I've been saying this for years, even before it became a trendy message board topic.
Those of you people who want to "save AM" I hope have a programming and sales plan for when all meaningful spoken-word programming is carried on frequency modulation-- and there's nothing left for the 90-year-old dial but foreign language, brokered religion, and perhaps an aging disco DJ willing to pay-for-play.
Despite AM's limitations on fidelity, it has an advantage over FM in that it can broadcast for hundreds of miles at night with the right amount of power.
Sorry, but nobody cares. Seriously. Even radio professionals today don't care. This is something only brought up by DX-ing radio geeks (of which I was one back when there were things worth listening to-- and it was possible here), a handful of old-timers, and perhaps a few FEMA bureaucrats. We can't even get most people to listen to full-power hometown AM and you're telling me about distant, fading signals laypeople in a given town have never even heard of?
Whenever there's an emergency which covers a significant portion of the country and radio service is destroyed in one community, other stations in a more distant community can compensate for the loss.
With what, their own feed of George Noory or Mark Levin to make up for the lost local one?
This is precisely what happened in 1989 when Hurricane Hugo ravaged the lower East coast. Many stations were knocked off the air and about the only means of communication was through the AM powerhouses!
So this is AM's business plan? Hope for a terrible disaster so people can be "served" by powerhouses? (Most AM stations, of course are not powerhouses.) Besides, in 1989 people still regularly relied on radio for important information. Radio threw that away by eliminating 99% of the news service that existed at that time. Maybe in another 22 years we'll have an instance where AM radio can shine.
To be fair, WWL did shine in '05. Just like it was supposed to. Props, as the kids would say. Meanwhile, every time there's a little storm somewhere we get these stupid industry-self-congratulatory stories in the trades about how a station "served the community" during the ordeal. "What, do you want a cookie for that?!" That's your job.
And daytimers? Are you kidding me? Try explaining to a non-radio person in the year 2011 the concept of ANYTHING that only works between sunrise and sunset. Not even a consistent schedule, like 6 AM to 6 PM. "Well, in June we come on at 6:15 but in July we're on 'til 8:30 but in December we have to shut down at 4:30 just as drivetime's starting-- got it?" Don't tell me about physics. Don't tell me about propagation. I know all about that-- remember I'm a recovering radio geek myself. Try telling it to listeners. Try telling it to advertisers. You can't. They won't even stick around for half the conversation.
Try hitting on a pretty girl in a bar by telling her, "I'm on AM radio." It hasn't worked since the early '70s. (Actually women today usually aren't even impressed if you're on FM-- but at least we could get away with using that into the '90s.)
Since there are already a billion AM sets in American hands right now, I have no problem designating clear channels for some kind of emergency service. Otherwise, I say turn the rest of the band over to the Part 15-ers and make it "CB Radio" people can actually use-- if they want to (and most won't because most don't give a damn about radio anymore). At least in the hands of amateurs there might be something worth listening to from time-to-time.
I love the idea of long-range listening. I even sometimes like the sound of AM radio (provided there's no interference). Really, I do. There's something "romantic" about hearing music on AM today (for example, on WHAT or WEEU).
But romantic isn't going to save the industry.
"I just want to save you while there's still something left to save."
Radio doesn't need rallies and flunkie NAB cheerleaders. What it needs is some tough love. It needs to be scared straight.
