93.7 FM NOW IN IBOC/HI-DEF ???

O

OldChicago

It sounds as if 93.7 FM is now transmitting in IBOC DIGITAL mode.
There is a buzzing sound on either side of the carrier which is usually
a sign that the station has a digital stream under their analog signal. Can someone confirm ??

KKRW is listed on Ibiquity's site as operating with their IBOC Digital system, as well as KLDE 107.5 and KPVU 91.3. I can't imagine unless you lived in far NW Harris County hearing KPVU in the Digital mode. Ibiquity does not list KIOL 103.7 which is definitly running IBOC. KIOL was just running an open carrier for maybe 15 seconds the other day and could pick up the digital hiss.

On the list with the Software and extortion money paid is KHPT, who I thought was supposed to be on the air with IBOC last year? Oh, that's right it is a Cox Radio station, no telling when they will actually get the IBOC on the air. KCHN-AM, Multicultural Radio Broadcasting's 410 watt daytimer has been listed forever as being licensed but not on the air, not that anyone would care. New to the list is KSBJ 89.3 and KRBE 104.1. Ibiquity does not do a very good job of keeping the list up to date though.

There was a poster on this board a few weeks ago that heard KKRW's morning show plug the HD Radio capability, but this is the first confirmation of such.

I've heard the hiss on either side of KKRW and KLDE, but not on KPVU, and I'm in NW Harris County...when the tropo dies down I'll check 91.3 again.

From what I've heard so far here and in DFW, FM IBOC is relatively harmless. On the other hand, the AM version is a bloody mess--on my last trip to DFW I checked KRLD 1080 and KMKI 620, and the IBOC was blanketing everything +/- 20kHz either side of the main signal. Same deal with WOAI 1200 when checked in Austin a couple of months ago.

Haven't heard anything about which Houston AM will be the first to launch AM IBOC.

Thanks to an earlier poster on this board with the update on the Senior Road IBOC update. Looks like we'll be seeing lots of FM IBOC signals by mid-September.
 
So that explains why my car radio...(Re: 93.7 FM NOW IN IBOC/HI-DEF ???)

...stops at 93.5 and 93.9 when doing a dial scan?

But I thought the adjacent channel problem was inherent only to AM.

BTW, my car radio scan does not stop at neither 107.3 nor 107.7<P ID="signature">______________

Mediafrog, the only AM station officially licensed by Ibiquity for Houston-Galveston is KCHN 1050. I would be surprised if they are the first IBOC AM station though. You can check what stations are licensed and/or on the air by going to www.ibiquity.com and clicking on HD RADIO at the top of the page, the next page click on STATIONS ON THE AIR on the left side. This will take you to a map of the US and you can click on each state and a listing by market and if the station is on the air on or not yet will come up. It is not up to date however, it does not show KIOL or KRLD on the list at all.

On the air AM US-74 stations from FCC TX-2 stations from Ibiquity..
FM US-311 stations from FCC TX-17 from Ibiquity.
This out of a total of 4761 AM stations and 6202 FM Commercial stations and 2551 FM Non-Commericial stations as of March 31st, 2005 released 6/7/05 by the FCC. Translators and Booster FM stations were not counted in the totals.

Distance to/from the transmitter plays a role in whether or not you'll hear the hash on the adjacent frequencies. As you get closer to Alvin, you'll start to hear the digital noise on 107.3 and 107.7. Obviously, the adjacent frequency noise doesn't go as far as the main frequency analog signal. <P ID="signature">______________

I was told that KHPT turned it on a couple of weeks ago, but I don't have a HD radio to verify.<P ID="signature">______________

Yes, they are running IBOC.
