And from elsewhere on the web:
Is AM revitalization a cover to force an all-digital transition?
Posted on April 17, 2013 by Paul Riismandel
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.)
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.
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.
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.
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.
