What You Pay For When You Buy an HD RADIO...

[radiopilot]

This is a very interesting article regarding REAL engineering test of the Sangean HDT-1 reciever and waht you get for your hard earn dollars...

What you will get is a real description of WHY IBOC causes the noise on analog and also why it would also produce noise in the HD mode...

Beware this is for TECHNICALLY inclined individuals....

http://users.tns.net/~bb/hdt-1.htm

Then the author goes on to describes ways to FULLY eliminate the HD noise... as simple as turning the stereo indicator to mono.... but alas millions perhaps billions of radio in the market now do not have this stereo to mono button, so they would receive the full noise from the HD sidebands...

Proven facts....

http://users.tns.net/~bb/hdrsn.htm

Then the Ibiquity corporation execs ACTUALY admit to the scrupulous dealings of HD and why everyone MUST use HD or you're SMOKIN' DOPE!

Utter bs is what it is. I'm not even going to read it, because I know the truth FROM PERSONAL EXPERIENCE WITH MY RADIO!

After spending an hour re-reading this article, which I think I read earlier, though this had a recent date...

I decided to get my headphones on, and listen to commercial FM, which I abandoned back about '85 with a
few exceptions. Like WNIB 97.1, now WDRV?, and WFMT 98.7.

Since then most FM listening has been from local college and universities, re-piped to pt 15 AM 1550 over various radios.

So I'd never been listening closely to what they were sounding like, they sounded "OK" as I'd tune by on the car radio,
maybe seeming a bit mushy to tune. Now that I listen for the whine to either side identifiying an HD signal,
then really listen to the noise floor (when there is dead air), and all the HDs have a low level of gently squishling mush,
sounding much like the noise floor of cheap cassetes, dirty viynl, or mild FM interpath.

As the article predicted, this noise is eliminated in mono, and sounds pretty much like the multipath effect I used to hear when I lived
45 miles from Chicago, and cleans up just the same by switching to mono.

Only now I am 7 miles from downtown, and should be able to decode FM stereo noiselessly here.
Indeed, on all HD signals, the "window" within which the stereo pilot lights is now razor-thin.
WLUP 97.9 (alone) will not lock into stereo ? but this may be an aberration, I am listening for a break to see if hear the pilot, it does
seem to be there..and indeed it is!

I now put the audio on AM 1550 w/unlimited hi-end audio, and presto we hear a 1 khz at 1569 off some 1570.
WLUP jock is now reading a reading an HD card. HA I can't even hear him in stereo anymore, and he wants me to buy a NEW radio?
Well, at least it's full meter signal, and clean mono, but the sidebands have wiped out my WLUP stereo.
Here's another good one....full signal meter, perfect center, and turning on the muting blanks the audio.
That's how much my Sansui TU 7700 likes HD on WLUP.
No monkeying with antenna rotor, pre-amp, bypass, and/or attenuator fixes this.

Thank goodness the the colleges and universities probably won't be able to afford this.

Thank goodness I don't use headphones for FM.
Will most people notice? Naw, just like the everything else made more cheaply than it's predecessor,
you sell 'em a new one on flash and style with marketing sizzle.
And hopefully you get them to keep buying a new one every so often.

It's just such an incredible thing that an FCC entrusted to manage the medium has put my stereo decoder on the fritz,
which I now notice causing occasional strange dropouts on the right channel of WCKG 106.1.

HD can now bring "fringe benefits" listening enjoyment to every analog radio right here in the city grade signal!

Built in multipath for no extra cost! Thank for all the mush on FM, ibiquity!
This sounds awful when you listen to voice only with headphones.

Bridge stereo at the audio outputs also seems to cancel all the noise.

HD = Headphones Decommissioned

I could still live with this ibiquity would come to its senses regarding the AM.
Mike, are you Really Sure you don't hear this at all on the best analog/HD signal you get, using headphones
and some other tuner you regard well?

I'm not saying it's "destruction" like some, but it IS there, on every one.

Consumers report one problem after another with HD stooge-radios as cheerleaders dissemble. And we wonder why this system stinks?

It's DOA. Let FCC bless it 'til the cows come home. Who cares? As with all scams, it will fail.

If you look at TSL or AQH during the past four to six years, especially among the lower demos, they're only going in one direction: down. I'm not saying it's the death of radio; I'm saying this is a question of growth and asset value. If you look at what Wall Street has done to our stock multiples during the past 18-24 months, it's also a question of the way we do business.

and, speaking about HD2:

Could this secondary audio channel be a subscription service?
Absolutely...... But this could take many forms, including premium services, concerts and who knows what else? The radio guys will decide this. [Entercom CEO] David Field is saying, “Let's string together some national networks and offer a satellite-like service, but do it better and cheaper. Maybe that's a way to combat satellite.” There are a lot of great business ideas out there, but out of the box, this appears to be the first killer app.

The opposite of what IBiquity supporters here have been claiming. So who has been "smokin' dope"?

When I buy a product I expect to get at least my money's worth... I have installed IF filters to receive DX signals on my tuners (I'm a FM DX'r) and I love doing all sorts of mods on radios so I get to see the guts of the radio... but to buy a Sangean, Boston Acoustics, or or HD radios to see the guts... and then see that it contains about $20.00 worth of OEM parts after spending upwards of $300.00 would send me off the roof!

Just go to the article on the Sangean HD-1 above linked and see what I mean... these HD mongrels have taken the once beautiful piece of radio engineering and turn it into digital crap.

Just look at some older pieces of radio tuners and see the guts of the tuners to see what I mean....

Then then the HD radio consortium will tell you that you have to 'scrap' that old analog radio (s) for some of us tuners which costs us anywhere from $100-3,000.00 maybe more for the new empty boxes devoid of any real engineering and beauty so that you can be overwelm by the NOISE!

I THINK NOT!

Terrestrial radio will be analog compatible for a very long time.

The FCC has neither guaranteed you nor broadcasters protection of distant signals in the daytime, and only to a few AMs at night. Ever.

I'm not talking about distant DXing or whatever anyone calls it, but right now in Savannah we get non-HD signals because no broadcaster is using HD transmitters so the noise is kept to a minimum even if alot of the programming isn't great.. you can read about it in the Georgia/Savannah section... but what happens when the HD consortium comes around and those stations I used to listen to noise free is now jammed with HD shower hiss? Am I to bow down and say the FCC doesn't protect me or the countless thousands here in Savannah? What then?

The only reason analog radio will sustain itself is because the broadcast industry will not self destruct and turn off the analog signal as that would be a death of terrestial as we know it... of course the mom & pop stations, college stations smart enough not to switch to HD, the part15's, and pirates as some called them would be the ones to reap the rewards....

Maybe it might be a good thing for the NAB to pull the switch on analog now!

Since you posted a 2005 artical earlier maybe one from today might update the story. What say we have a look, OK?

Yeah, I read that article earlier this morning... in fact I got the wheelbarrow collecting all my analog radios as we speak to take them to the dumpsters...

What does this change... You think NOW the general public will be scrambling to all the retail outlets to buy HD radios?

We'll see how much interference the listeners will enjoy at the massive level.. who knows in this business...
