Skip to comments.A Quest to Save AM (Radio) Before Itís Lost in the Static (caused by cellphones and other devices)

...at least one man in Washington is tuning in.
Ajit Pai, the lone Republican on the Federal Communications Commission, is on a personal if quixotic quest to save AM. After a little more than a year in the job, he is urging the F.C.C. to undertake an overhaul of AM radio, which he calls the audible core of our national culture. He sees AM largely the realm of local news, sports, conservative talk and religious broadcasters as vital in emergencies and in rural areas.
AM radio is localism, it is community, Mr. Pai, 40, said in an interview.
AMs longer wavelength means it can be heard at far greater distances and so in crises, he said, AM radio is always going to be there. As an example, he cited Fort Yukon, Alaska, where the AM station KZPA broadcasts inquiries about missing hunters and transmits flood alerts during the annual spring ice breakup.
When the power goes out, when you cant get a good cell signal, when the Internet goes down, people turn to battery-powered AM radios to get the information they need, Mr. Pai said...
...But why try to salvage AM? Critics say its decline is simply natural selection at work, and many now support converting the frequency for use by other wireless technologies. A big sign of AMs weakness is that one hope for many of its stations may be channeling their broadcasts onto FM.
... Im obviously bullish on next-generation technology, Mr. Pai said. But I certainly think there continues to be a place for broadcasting and for AM radio....
...Nearly every recently manufactured electronic consumer product... emits radio signals that can interfere with AM broadcasts....

Is AM revitalization a cover to force an all-digital transition?

The AM bandwidth is around 1 MHz...not much use for the types of bandwidth needed for cell phones/etc.
Plus, mod/demod for AM is infinitely easy. And...receiving a signal requires only wire, a headphone, and a crystal diode. (Yup, cell-kids, it’s the ultimate in simplicity - but beyond your texting abilities. Well, beyond most of you anyway.)
When Hurricane Ike hit Houston, it showed the folly of digital reception-ept-ept-s-——ept. So much for listening to storm updates.
And electric cars aren’t much good when parts of the city are without power for over 30 days (and a majority without power for up to 7 days).
Oh, go buy a generator and get some gas you say?
Interference to AM radio is common from switching power supplies used in most electronic equipment. Your AM radio will often work better in your car than in your home, because you are further away from the sources of interference.
Cellphones operate at much higher frequencies. Any internal switching supplies they have operate at very low power, so they are not the source of AM radio interference.
This is political, the leftist want to squash talk radio. This is a veiled attempt. Don’t be suckered.
We are being sold better-mousetraps not because they are actually BETTER (they come with tradeoffs) but they are mandated by Congress/Presidents.
Non-filament lightbulbs, low flow toilets, electric cars, freon-free cooling systems, digital television...
I am often told that CDs sound so much better than scratchy records. CDs can get scratched too (and digitally rot over time). A scratched CD can sound far worse (unplayable) than a scratched record (the player for which can be more forgiving). But the music companies made good bank rereleasing albums (at inflated wholesale costs for DECADES) on the “sexy” Compact Disc format. Today, they are rereleasing albums (at inflated wholesale costs) on the “retrosexy” vinyl format (petroleum price is a factor in costs, reduced number of pressing plants with a scarcity of replacement parts is also a factor) but not every company is seeking a $20-30 pricepoint for records these days.
Leftists have pretty much given up on their jihad against talk radio. The average talk demographic is now over 50. People under 40 have no idea what AM is. People under 30 don’t even listen to radio, and the Obamabots have largely captured them on their wireless devices.
They are just sitting back waiting for us and/or the technology to die off.
I’m still waiting for McCain and other to retire.
At least Red Ted Kennedy is gone. Orwell had him pegged.
Pretty much pseudo-science BS, about what you’d expect from the MSM/NYT.
True, the switching power supplies that have been forced upon us as part of “going green” emit all sorts of RF noise, but it’s manageable unless you’re in a really weak AM signal area. Computers and lots of other stuff make far worse, the bigger problem is that all these unintentional emissions are supposed to be be mitigated by the manufacturer, and the FCC does nothing to enforce their weak, self-adminstered rules.
There are many who’d like to force AM into a digital transition but there are better reasons not to. Not the least of which is obsoleting the entire installed base of radios back to the early 20th century, and in a time of emergency, our national interest is far better served by a radio transmission mode that can be picked up with a razor blade and piece of wire vs. on that requires millions of transistors in a costly and power-hungry digital decoder IC.
I call BS on it.
And...receiving a signal requires only wire, a headphone, and a crystal diode.
I thought you needed a wire (antennae), a simple lrc (inductor, resistor, capacitor) circuit with a variable resistor as the r, a battery or ac power with a ac to dc transformer, and an amplifier tube or crystal diode.
Right indeed: http://makearadio.com/crystal/index.php
I am old, I built them things and used them just for fun.
As long as there is an AM station in relative proximity, they work fine.
My last three new pickups have had increasingly bad AM radios. If I am in the mountains they get fair reception, but once I get next to a power line, there is huge static. I don’t remember power line static 30-40 years ago.
Driving alongside of any Metro bus in my cities results in audible AM radio static.
I guess the FCC isnt happy with how long its taking the old man to die, so they are wanting to take a big old needle full of Strychnine and put it right in a main artery to speed up the process.
Making obsolete every radio receiver that has been made in the last 100 years. Are they out of their mind?
Digital transmission on a crowded band that is ill suited for such transmission system. Are they out of their mind?
They know dang well what will happen. Just like they knew dang well what would happen with the digital TV transition.
I am sorry FCC, we dont want your medicine. AM radio has lasted a 100 years, and it will probably last another 100 without any help from you.
I am personally a little more paranoid on this. I think they want to force all mass communication to the Internet, where they can monitor who is watching/listening to/reading what.
They need to drive a stake through IBOC and leave AM alone. We need one long distance, reliable, technically simple, and untraceable means of mass communication.
Once upon a time, making a crystal radio was a rite of passage for every Boy Scout... but that was before the Faggotry and Twerking merit badges were created.
