HD In the fringes?

J

jras20

I gota question about the fringe areas, since i'm in one :( but how well will the HD signals travel through? I hear some say it wont work, but I can hear the digital noise in the sidebands when I tune in, would that mean it would work? Gues I could hookup a bigger antenna on my truck as well. But has anyone tried it in the fringe?
Thanks
 
How far are you from the station you want to hear? How much power is the station running and how far average terrain are you and the site? One last comment, if you can hear the sidebands and there isn't so much interference as to make the information beyong the radios error correction capabilities, there's no reason you can't receive the HD signal. I am guessing you are talking AM here. If you have a local store which sells the radios go in and ask for a demo.
 
Its about 86 miles from Houston, I can hear the digital noise in the FM bands, I can also hear it in the AM as well. The only problem is sometimes I will get skips from either Corpus or San antonio.
 
Jras20, I hope to buy the Radiosophy unit when it finally ships. I am also in a fringe area. I am 115-130 miles north of Albuquerque, New Mexico and I can hear some noise on sidebands, depending which radio I use, as well. If it's not too late for you then, I'll be sure to give you and everybody else here at Radio-Info a report. :)

As a VERY general rule, any type of radio transmission (analog or digital) will cause interference at a much greater distance than it will provide useful service.

I have a Boston Acoustics and live 18-30 miles from the Nashville stations. The four FMs are all Class C or C1 (100kw) and the one AM is 50kw. (WLAC 1510)

I can get one of the FM stations reliably if I put the radio in the ham shack & move the provided wire antenna *just so*. Otherwise, I have to hook up the TV antenna to get reliable FM HD reception. Reliable digital reception of WLAC-AM requires that I connect the 130-foot ham antenna; the provided AM loop antenna causes the "HD" indicator to blink and with considerable manipulation I can get a second or two of digital audio.

Reception of these powerful stations with an analog receiver is easy & reliable with the loops and whips provided with typical "boom box"-type radios.

YMMV - the Radiosophy may behave differently. I'm beginning to wonder if we'll ever find out!
 
Many of the HD Receptors have sensitivity issues. I know of one receptor which can only receive A 50 KW AM IBOC signal when placed inside the transmitter building. My HD is fine and I receive every NY area HD signal with the dipole B.A. mailed. I'm waiting to read some reviews about other HD radios before I conclude that there are transmission issues. I've heard the JVC HD 1 is really excellent. Can anyone with a JVC comment?
 
I didnt like my JVC analog FM tuner in my Truck it was not sensitive at all. It had a cd player on it also, I hardly used the cd player I mostly listened to the radio. I wasnt to pleased with the FM reception on it. So I took it out and put in my factory fm/am radio and it picks up a lot better! I want to get a bigger antenna if I could, does anyone know where they might sale fm antennas any more? I couldnt find nothing at Radioshack.
 
Unfortunately you can't compare an analogue radio manufactured by JVC with another model. There are too many variables. If you have an antenna on the fender of your vehicle that should work fine. I'd suggest finding a place which specializes in car radio installation
 
I'm wondering myself about the Radiosophy!
 
I have the JVC first generation HD radio in my car. HD reception in fringe areas is horrible probably because of the sensitivity of the radio itself and the low power of the actual digital signal. I notice stable HD signals of stations from Philly and NYC are limited to about 30-35miles (beyond this its variable based on terrain etc.) but this is over open flat terrain through hills, tees and buildings into the mix on fm even inside the primary service areas and the HD ditigal goes bye bye that on FM HD signals; AM are still plagued by overhead power lines making the HD signal go off. Just a waste of money if you spend your time in fringe areas. Seems like HD is well suited for stationary radios....

Yea, this technology is a real joke - once the digital signal drops out, after a short distance, the analog kicks in. If you go over to the Google Group, rec.radio.shortwave, and look at numerous threads, you will see that people are having all sorts of problems, with this technology ! HD Radio - what a joke ! Well, there is first-hand proof, folks !

Funny thing, with analog AM/FM radios, such as my Radio Shack model-12-898 digital PLL, with its internal ferrite-bar antena, I don't need an external antenna, and it is portable - I can take it anywhere with, "no muss no fuss" !

Again, first hand proof, with HD/IBOC adjacent-channel interference - this is just, "a tip of the iceberg" !

Please re-read the posts concerning the limited coverage of early current band FM. Radios have come a long way since FM first appeared. This fall there is talk of a second generation IBOC radio. We're at the infancy of this technology. You and other DXers obviously don't represent even 1% of the population and to be honest I might sympathize with your point, even though legally it holds no water, if you could only DX the broadcast bands. There's all sorts of spectrum out there to DX. Sometimes adjustments have to be made to live in the world with other people. This should be your biggest setback.
 
You need to post some links, to back up your claims. I was just thinking, with all that HD/IBOC digital hissing, you could pretend that you are Dxing, just like with the regular analog ! Oh, in the following link, I was just reading how auto manufacturers, not interested in HD Radio, are really excited about putting Internet connections in their automobiles - how cool is that ! Then, one could access EVERYTHING - Hi-Fi radio, to get stations from around the world, if stuck in traffic, one could check out the highways's web cams, and I guess, even look at porn ! How cool !

The iBiquity site has full data on the version 2.0 design specs, and the receivers wil be in stores in late August or September. Announcements from places like radio shack,, Best Buy and so on have been made about stocking many of them.

We will see, if that happens. But, still no interest, no HD radios ! Check out this graph - oh, well:

Since the marketing has not started, this would seem logical...

HD Digital Radio Alliance
Awareness Campaign Set

The HD Digital Radio Alliance has stepped up its efforts to accelerate consumer awareness of digital radio by launching a new branding initiative centered around the marketing slogan "Discover It!" A series of 30- and 15-second spots are scheduled to debut Monday on every station that's part of the alliance in 50 radio markets, and the commercials invite listeners to discover "new, free, digital quality radio programming" and new "stations between the stations" — HD2 and HD3 multicasts now on the air across the U.S. The new commercials are scheduled to air from July 31 through Oct. 1.

That will make no difference - no one will be interested, especially, with automakers excited about putting Internet connections in automobiles. Having wireless Internet conections everywhere, will also enable Wi-Fi everywhere, and both will kill Satellite and HD Radio - just look at the graph. Doesn't take a rocket scientist, or dummy like me (right, David), to figure that out !

The graph is of one study. A prediction, as it will. No one knows how this is all going to play out by 2020...it's just a study. And nothing on that graph shows the "killing" of satellite radio or HD radio... it just purports to predict market share.

And by the way, I'm not an "apologist" at all. I have no dog in this hunt, and I do think many are underestimating the impact of mobile Internet radio in the future.

But...a lot of things have to come together for that to happen, and it hasn't, yet. There is no sign, yet, of either A) widespread availability of Internet-connected car radios, even in the future or B) ubitquous WiFi or low-cost mobile Internet connections. (Yes, I know about WiMAX, and no, it's not widely available or even beyond the test phase at this point.)

IF all this stuff comes together, THEN I agree we've got a game changing scenario. I also believe the smart operators are already on top of this, and are moving to go beyond the transmitter/tower/over-air scenario.

Your problem on this board is that you are a one note poster, based on your login name (thanks for changing it, by the way). Your sole purpose here is to rant and rave against one digital technology. That lowers your credibility in my mind. I'd like an honest, open discussion about this without having to deal with someone whose username tells me everything I have to know.

I am amazed at the stuff you find convincing. You take opinions by people not in radio over those in the business, and graphs of interest in thi ngs not yet marketed (it starts tomorrow, BTW) as indicitive of behaviour. Gad!
 
Keep blowing hot air - everyone at rec.radio.shortwave have called your bluff - even Brenda Ann caught you in a lie ! Oh, I would say that Mark Ramsey is in radio - another bluff !
