Portable HD receivers are coming in 09

Well Coby Electronics have the first portable HD radio. Is it any good? Who knows.

It's a single speaker, bookshelf size radio that runs for a couple of hours on a charge. Wanna try jogging with that?

Jogging with the radio? How about the Yagi?

No worries, Clouseau. Actually we "went HD" two years ago 24-7 at WYSL.

Well, actually, we went "HD quality," and unlike IBOC I actually mean "High Definition."

We decided to dump the 6kHz bandpass recommended by our consultant for "maximum coverage and penetration" and defiantly opened the Omnia up to 10kHz. You know, precisely the opposite of the Jeff Littlejohn "prevailing wisdom" about bandpass and crappy consumer radios.

The improvement was dramatic. With the Nautel pumping out 21kw into the phasor, and the transmission lines carefully equalized, the station sparkles. Nice brilliant highs, thundering locomotive-solid low register, high intelligibility. Sounds great on wideband car radios. And you should hear it on anything from boomboxes to table radios to 1950s "All-American Fives." Blows away the local IBOC 50kw mudbox, even five miles from their transmitter. We get compliments from peers, listeners and clients all the time. I think it actually sounds better than many FMs in town. Given that the extreme processing on most FMs produces equivalent bandpass of 12 to 13 kHz, the 10kHz transmitted by WYSL is indistinguishable from those FMs by the average listener.

So much for "AM can't compete because the audio quality sucks."

And no expensive new, 4-hour battery-life radios are necessary to get that quality.

Mr. Savage, why are you trampling on the poor WBZ listeners in the Rochester area with 10khz audio? Instead of hearing a nice clean signal, they are hearing splatter from WYSL. How are the WBZ listeners near Avon supposed to null that out? ;D

That's determined by the way the tin foil hat is shaped. Dummy. Worn toward the antenna as you start your run and worn in reverse as you head home. Don't you know nothin'? It's the mobile ground that's the problem.
 
Len, you "card....." :D

WBZ listeners "in the local area" are actually gratified that "unlike some broadcasters utilizing IBOC" WYSL respects the RF territory occupied by our first-adjacent neighbors. Even with 10 khz audio we maintain strict adherence to modulation limits and of course use the NRSC pre-emphasis and filtering.

WBZ is perfectly listenable even within our main northern lobe at night. As long as you want to listen to telephone-quality analog audio with no highs or lows, that is.

Of course OTOH WBZ continues to stomp us, and KDKA, with its hellish digital noise extending to 1045+ kHz. All to "serve" the 14 listeners (including Mark Manuelian and WBZ personnel and competitors' engineers) in Boston listening in digital.
 
Mr. Savage, of course I was kidding. Your station sounded great when I traveled though WNY on the Thruway and US-20. As a recent politician said: "I feel your pain" with respect to WBZ. I suspect WBZ will cease to be a problem for you when the realization sinks in that AM IBOC is worthless considering all the damage it causes. However, as a AM DXer, I would like to see IBOC disappear as well as limiting stations to 5 khz audio. If the stations from Cuba and Mexico shut down, that would also help clean up the band. With that being said, I wish the posters here would lay off FM IBOC.

Why?
FM HD Radio is defective and deceptive too, and deserves no better fate then AM HD radio.
 
The FM system will not suffer the same fate as AM. I predict that the FCC will approve the 10% injection and IBOC will slowly be incorporated into radios. Digital broadcasting is superior to analog and if 10% injection interferes with the analog signal, perhaps it will hasten the conversion to an all-digital system.

This is what's known colloquially as a conspiracy against reality. With something between 800 million and 1 billion analog radios already in use in the US, ruining analog reception will result in the death of radio altogether long before there are enough HD radios in the hands of consumers to prevent said death. Further, the resulting backlash among radio users, who currently hear nothing wrong with the sound of their radios and who see no reason to switch to digital (as has already been more than adequately proven by the moribund sales of HD receivers), would doom any such conversion.

Proposing to ruin the medium where radio makes its money (and just for your reference, that would be the analog signals) is just plain stupid.
 
I believe FM iBlock will go away just as AM iBlock, it may take a little longer but it too will go, why? Because there's no good reason to keep it and many good reasons to dump it, like high fees, lousy range, artifacts, interference to other stations especially if that 10% injection increase is granted and also the fact that it rarely sounds better than analog to most people, so there really is no need for it. The HD-2 channels are almost universally lousy and sound like an afterthought, but the number 1 reason it will go is because still no one is buying the receivers and if no one is buying the receivers after all this time, they're not going to. The Hula Hoop came and went in less time than this, (and it did what it was supposed to do).
 
I can assure you that there will not be an HD receiver in MY house anytime soon... for the following reasons:

The sound quality available with a 32 kbps stream is significantly inferior to high quality analog transmission. It's not even in the same ZIP code as high fidelity! For those of you whining about S/N, my own Pioneer tuner was measured by a respected test lab at 90 dB in stereo... which is more than adequate for any listening environment available to me.

I will not give iNiquity the satisfaction of paying one dime for a receiver incorporating their inferior and interference-causing technology-- AM or FM band. And, by the way, HD Radio offers nothing that I want to hear. If the choices available to me on terrestrial analog broadcasting cease to meet my needs at some point, I plan to either purchase a satellite or Wi-Fi radio.

America is the land of the Almighty Dollar. Therefore, the way to stop this insanity is to vote with your pocketbook! Don't buy this junk! Don't patronize any organizations that support it. Don't listen to any broadcasting stations that use it. And while you're at it, tell your friends not to buy HD radio either! And tell them why!

Many posters here think (and hope) there will be this huge backlash, but that won't materialize. The only people affected will be the out-of-market listeners that listen to first adjacents.

So you think! Many of those so-called "out of market listeners" that will be negatively impacted are not out of market. But they are going to be disenfranchised by the big monopoly-owned stations nonetheless.

That's another aspect of HD radio that makes my blood boil-- it is nothing but a thinly-disguised spectrum grab by the greedy and powerful!

Don't need it, don't want it. Make it go away!

If that 10db increase is granted by the new FCC guaranteed there will be a back lash and also guaranteed the FCC won't give a hoot, it is our "inevitable digital future". Unfortunately I believe a lot of political and radio hacks have bought into that hype, it will be consumer apathy that finally does "The Great Fraud" in.
 
Len, I knew you were kidding. And I thank you for your generous comments about WYSL's audio. We do take pride in making our station clean, loud and legal.

Even if it's AM. And mono. And analog.

If you're ever in the neighborhood in your travels I invite you to stop by. We're the only radio station I know that showcases its transmitting and phasing plant through an expanse of plate glass right next to the parking lot.

I thought this forum was for expressing differing opinions on this subject! Making insulting and inflammatory comments is a reflection of your character.
