Left behind thread was a mistke. Here is what I mean to say

I apologize for the previous post. I wrote the post below for this site and had sound questions for search engine optimization forum. The post above was meant to be pasted in that site and the following information is for radio- info I tried to modify it on this site but it would not let me
I thought HD frequencies are narrower that current frequencies but I read about the possibility of a HD station interfering with a analog station. Would someone explain this;

There are TV categorizes to post in but none about HD so I am asking here., With HD being mandatory what will happen to small market station who can't afford it.. Who knows they may be part of a government bail out tool. OK I am just kidding but seriously how will they afford it

"HD" is not mandatory. Only DTV is. HD Radio is pretty much an afterthought right now. It's simply not going to cut it in this dismal economy. Ibiquity will have to bring down their prices for the smaller stations, otherwise it will wither on the vine. (Which might be a good thing.) It would take at least another 10-20 years (maybe more) before digital were to go full-tilt and boogie (aka-"mandatory"). By then, better technology, other than I-BUZZ, will be available for even the smaller broadcasters to use. IMHO: It would be better for the smaller broadcasters to save their money for even better technology down the road.

The smaller (AM) broadcasters should be pushing for a mandatory AM receiver standard with C-Quam stereo, madatory noise blanker and full-auto adjustable bandwidth (or manual) out to 7.5KHz to as much as 10KHz in strong signal areas. That AM minimum receiver requirement would be a standard for any FM stereo radio, HD or not. That's what the little guys should push for, not HD-AM.

 

[Tom Wells]

There's no good good reason to stop at 10khz, if you read the actual bandwidth allocations plus protections as originally written by the FCC.
With a city grade signal, and properly controlled audio at the AM station so that "no" -100% occurs, 15khz is desirable.
As we must assume no one will ever build a proper analog tuner ever again, these digital radios need 4 or 5 steps for IF bandwith, 4 khz, 8khz, 10khz, 12khz, and 15khz.
Noise blankers should be switchable, as they often smear transients and punch, even when "level delayed" or gated.

While we're at it, we should make square-wave detection illegal for application in consumer AM radios in the United States.
You can NOT mix square waves and sine waves and expect the product not to be full of a multitude of harmonics.
They cannot be filtered out properly, and are another reason why consumers tire of "the sound of AM".

Johnny, I’ll “hi-five” you over your post... I AGREE! I recently purchased a Meduci AMX-2000 online from its inventor—Jeff Deck. It’s a “science-fair project” that actually is an exemplary AM receiver in disguise—the VERY BEST I have owned [including the famed Carver TX11]. The audio quality is exceptional... WIDEBAND and NEAR-ZERO DISTORTION... The PERFECT AM demodulator housed in this Radio Shack project box with a tuning mechanism reminiscent of a 60s-era 6-tansistor radio... ‘Looks “ancient” but WORKS! Maybe Jeff’s simplistic approach describes the technical requirements of “good ‘ole AM radio”... He certainly has achieved that... I’ll give him TEN STARS for his product.

As I type this, I am listening to my Meduci tuned to 1580 WIFE Connersville, IN—a station recently rebuilt with a new BE solid state TX and Omnia proc. Bob Hawkins is a “legend” in Indiana AM engineering and he directed the project—SUCCESSFULLY! It is so wonderful to hear GREAT QUALITY AM again. Let me add, I traveled north to Myrtle Beach, SC to listen to 910 WNMB’s oldies format in C-QUAM stereo on the Meduci tuner – SOUNDS AWESOME in AM stereo... ‘SHAME this system didn’t make it... HUGE LOSS for AM radio, but HUGE GAIN for those that find it today!

Let's "rattle the cage" and bring this back!
