Howdy y'all:
Everyone needs to pass this on to other sites please!.
In my opinion going am digital is NOT very smart of the fcc!.
To many issues like range coverage, interference issues, etc!,
There biggest concern is to make better am radio receiver like the GE super tuner radios
Back in the 1980's!.
Watch video and get your inputs to the Fcc!.
Hope you like
Station 8

I agree 100% with you and have been in discussion with another forum member on one of the Facebook part 15 forums. I don't care about what the commercial stations do. Just preserving our hobby. This will be all voluntary if passed and our hobby is safe...sigh of relief! Even though part 15 doesn't specify a type of transmission(yet) there will never be transmitters at the hobby level in the digital format and I don't know exactly how it works but I don't think digital is in "bands" with space to go where there's no stations like analog. Not only that but everyone is not going to be drawn to radio that doesn't listen to it now or go out and buy a digital AM radio just because it's digital.
And why would a station like Zoomer 740 here in Toronto that can be heard all over the eastern half of the continent at night want to go to a format of transmission that will make them local coverage only. Plus with digital as soon as you are out of a certain range, the audio, like the picture on TV will break up where analog can be received with intact audio with a weak signal?
I just don't see it. Why digital?
Why doesn't the FCC enforce their own rules for devices not causing interference.
And I agree that the radio makers can make good quality AM sections better than they do now. The super radios are a good example.

During today's FCC meeting according to Michelle Bradley of recnet it looks like it was unanimous and it has been approved and a voluntary basis. Though the FCC is not forcing stations to do this I'm sure as more stations begin broadcasting digital we're going to see quite a bit of interference on the band.
I also have to wonder if new stations are going to try and play the trick of broadcasting digital between 1620 and 1700 kilohertz virtually killing any hobby broadcasters left. We will have to wait and see how this one plays out.
There's a lot of political rat's nest involved in this one.

I don't think they will flock to the top of the band. What would be the point? What's wrong with anywhere else?
There may not be interference as it wouldn't be "riding" on the analog signal like the hybrid system. Most of the HD stations are on the FM band anyways.

Am only please!.
Since it's a digital signal, I'd wonder how well it would work at the top end of the dial, where there are stronger propagation effects than the lower end? Signals start to skip earlier in the evening and distant signals hang in there later after daybreak, and those beat with local signals, and skywave seems stronger at the top end, with more selective fading.
It seems like so little is known about digital on the AM band, why hasn't it been tested over a larger set of stations to see if it should be approved, it still feels so experimental to me.
I'd also like the DRM digital radio system to be evaluated. I don't really like them politically, just another big company that wants world domination with their standard of digital radio, but in the spirit of technical competition, it should at least be looked at.
