IBOC sidebands JAM DFW's airport station

[rbrucecarter5]

DFW airport has just lost a valuable asset to the travelling public. All so a TALK station on 1700 can run stupid IBOC. It is very hard to even hear DFW's flight information until you are whizzing past the terminal where your flight departs - the whole sequence on 1680 takes several minutes, and you can no longer hear the DFW station that far from the airport.

This is a travesty when local stations jam valuable information to the travelling public - so they can have stereo musical beds and stereo commercials.

Oh please. If it was that valuable an asset you don't think the airport would have fought harder to keep it?

And in this day and age, don't you think most people are using that thing called the 'internets' to find out flight information?

Keep what?

TIS services on X Band channels have no rights at all.

TIS stations at airports give last minute parking and drop-off or pick up info, not flight schedules.

 

[little1]

Okay.
So apparently we have a guy who's complaining that a service that has 'no rights' is losing their 'right' (that they don't have) to broadcast so that a a station that does have rights to broadcast can use thier "rights". Is that a fair statement?

And as for the 2nd part- is there that much of a difference? If I'm picking soembody up at DFW I'm either checking the web to see what gate they're coming into or calling the person on their cell phone...I wouldn't even THINK of tuning into 1680 for flight info...so we're back top is this really that big of a loss, or is this some bitter old fart bitching because he doesn't think a station 'needs' AM stereo...

I'm with Bruce on this one. To allow any radio station to splatter across four adjacent channels is inexcusable. The F.C.C. only has one real function any more: to make sure radio stations don't interfere with each other. Allowing this hash to propogate during critical hour periods will ruin a lot of radio station reception.

1680 does not give flights. It gives data on the accessability of the terminals and parking facilities.

The 1680 airport station should simply change frequency. It has already done so once before, having been on 530 back in the 80's. It was forced off that frequency when KDFT 540 signed on in 1987.

No. Check Grantchester's post for the core issue at hand.

WRONG - it gives gate information. And when it is American - you can end up at the wrong terminal if you don't know the gate. Yes - people check the internet for gate information. But flights change gates all the time. It helps to know minutes before you arrive exactly which terminal - A, B, or C to park at, and where in each terminal to park (to avoid a half a mile walk).

If nobody uses 1680 - why do they bother broadcasting it? I have used the TIS stations for years.

My like or dislike of IBOC has no bearing on the issue. The issue is interference to 1680. All so a TALK station can have stereo commercials and stereo musical beds. EXCUSE ME if I think travellers going to the right gate at the airport is more important than stereo on a TALK station.

I must not get out enough, because I had no idea this service was available. ???

I am too. I live three hours away from DFW airport. When I leave home, gate information either isn't available, or it isn't correct. Yeah, I have a cell phone, but calling in for gate information and using your phone’s keypad to access the information while you are driving in the traffic around the airport is just plain dangerous. The TIS station is a big help and serves a public need. I’ll venture that a lot more listen to the TIS station every day than tune in the new HD-AM.

If an analog station splattered across four adjacent channels, it would most definitely be in violation of the rules. AM has enough problems from other man made interference without adding more of it from your fellow broadcasters. I'm all for digital radio, but there must be a more efficient way to do it.

I agree with Bruce and Grant on this one. I had to take my wife to DFW last June. We checked the internet info.,etc. By the time we got to the airport 45 min. later the information had changed in regards to gate number and parking. The DFW radio worked ! She didn't miss her flight or was late. The CONsultant was wrong on this one,once again. Grant is correct,ANY station causing interference to another should be investigated by the FCC.

 

[Tom Wells]

Same thing in Chicago, WBBM @AM 760-800 wipes out both the Midway and O'hare airport TISs at 800khz.

Funny, there USED to be enough room for all these signals. I wonder what's changed?

Oh, that's right, the "special intentional interference mode".

Love ya, ibiquity. Have a nice day. Die with dignity. May your fortunes be in keeping with your propriety.
If they'd only had the sense to keep this thing off AM.
Criminal trespass is the same in RF as any other property.
Count me as another who wants the IBOC AM nightmare to end.

If these info stations were worth adding, they are worth protecting, even if they were "shoehorned" into whatever spot was clear enough.

What a minute!!! HOW can 1700 be running IBOC when its MANDATED in part73 that X Band stations MUST run C-QUAM AM STEREO...thus preventing IBOC!! HMMMM me sees something funny here....

He aint the only one....AM IBOC was a mess from the start...and if ever gets nighttime authroization, it will be a TOTAL disaster..there are better ways to do it now. The jury is still out on FM IBOC in my book.

 

[little1]

Okay, so now that all you experts have weighed in again, can someone explain it real clearly for me, please.
We have a station 1700, that for whatever reason is broadcasting in stereo. And then you've got the airport info that is being broadcast at 1680. Which isn't an actual radio station, which means they don't have FCC protection from interference, etc, right?

And so you guys, posting on a radio board, are bitching about the radio stations actions, and not about the info service broadcast...Is that correct?

 

[oldiesfan6479]

IBOC is a four-letter word.

But unfortunately, it is one you can say--and transmit--on the radio.

Sounds like you have something to do with 1700. Refresh my memory, though. Talk is essentially a MONO process, right - every individual has only one mouth. So what possible benefit is STEREO to a talk station? A lot of FM talkers even turn OFF their stereo subcarriers. And the human voice is essentially limited to frequencies under 3000 Hz when one is talking. So what possible benefit could be derived from expanded bandwidth?

So 1700 insists on broadcasting HD, when there is absolutely no need - except for stereo musical beds and stereo commercials. And in the process - takes out 1680. Excuse me - but I do believe there is a "real" station there. It has a carrier, which is amplitude modulated. The format is a little - limited. But I know some non-comm stations that essentially are automation hooked up to CD players - not a whole lot more sophisticated than a voice loop. Yes, 1680 is "real" station. I dial the radio to 1680, I hear a station. I dial it to 1700, I hear a station. No difference between the two in my book, except 1700 is stomping all over 1680 for no good reason. You would be absolutely furious if it was the other way around.

Another poster had a good point. Expanded band stations MUST be C-Quam, so 1700 is presently in violation of the law. As are quite a few other expanded band stations. Perhaps as a conscientious citizen, I should file a complaint with the FCC alleging a violation since 1700 is not C-Quam.

What really is upsetting is that the alternatives to 1680 - fumbling with a cell phone on the way to the airport - actually create a safety hazard on the road. I don't think stereo commercials or musical beds can justify putting the air travelling public at risk on the way to the airport. VERY irresponsible of 1700 to wipe out 1680.
