Full Time IBOC has been approved

If and when nighttime AM DX begins, the only good thing I can think of is that I have a great new DX target...trying to get SOMETHING, ANYTHING in AM HD in a part of the country where there are no stations. I've tried in the "critical hours" (right after legal sunrise and before legal sunset), but so far, NOTHIN'! With more stations on at night, at least I'd have a shot of getting SOMETHING, sometime. So while I think nighttime operation is a bad idea, the dxer in me thinks it would make for some great new targets. Will a tuned loop, carefully aimed, be more likely to pull in digital AM than, say, a random longwire, or a Beveridge? Time, and patience, will tell.

Interesting thought. I know I used to DX AM Stereo years ago. Lots of fun. I too am hoping to get a listen to HDAM at night. It's going to be interesting.

No, he's not blowing smoke. The page on digital audio may not have changed (yet), but the R&O has been issued. It's linked from the main FCC page, www.fcc.gov . Multicasting is approved on FM HD without requiring notification to the FCC, and HD is approved for nighttime use on AM, subject to clearances from Canada and Mexico and the setup of a system to handle interference complaints. The rules now have to be written and posted in the Federal Register, and will become effective 30 days after publication.
 
AM stereo was also approved, but never accepted by the market. It's as good as dead. What happens with IBOC remains to be seen. Maybe it will be so successful in the long run that the FCC imposes a full digital mandate. Maybe it takes off on FM but becomes de facto dead on AM until stations can go full digital, or maybe the decision gets amended to require IBOC shutdown after drivetime regardless of sunset time on AM. Maybe it becomes the next AM stereo.

One thing's for sure. The Commission approved nighttime IBOC but did not change the protected skywave contours of the clear channels. Clearly they believe what Ibiquity says about it not causing interference in the real world. We'll see soon whether Ibiquity is correct or not. If they're wrong, let the lawsuits begin!
 
AM stereo was never on 2000 stations (which HD will be by the end of summer...based upon orders already placed). AM stereo never had the momentum of new radios that HD does (though it was installed in lots of cars...and still is in some).

I've made the point before that, while AM stereo is used as the prototypical example of marketplace failure, there were actually millions of radios sold. New models have been introduced THIS YEAR! And AM stereo is not only standard, but quite successful in much of the world (Japan LOVES AM stereo). Many would enjoy that kind of "failure". It (am stereo) never "set the world on fire" here in the us. Instead, it brought it to a slow simmer ;)
 
AM STEREO was not and is not a "marketplace" failure. It is an FCC failure. The FCC waited too late to adopt a standard. My station broadcasts in AM Stereo and we have many listeners who hear it that way every day. We'll keep broadcasting this way until we quit altogether. Someone needs to buy the FCC some power tools so it can screw AM even faster.

Well, at least they didn't make that mistake this time.

I own a few AM stereo radios. In my area the only station broadcasting in C-QUAM AM stereo is WREF. It's a 2500 watt daytime station that's over 40 miles from my location. It's signal is weak and hissy at this location. The NY stations which at one time ran AM stereo generators have taken them off line. I've been told that WFAN used there's as a door stop.

Hopefully, they'll be using their IBOC exciter as a doorstop in the not-to-distant future too!
 
I got hired at a station in NJ that used an RCA 77-DX for a doorstop. I asked why, and was told it's "old and ugly". I took it home, cleaned the beast up and placed it in my newsroom. The never-around owner called and wanted to know why "the new guy" sounded so much better than everyone else. They were using new AKG's, I was using a 1963 RCA.

Maybe the Motorola generators will be as prized in the future.
 
On the FCC notice for adoption of IBOC there was this point:

"Dismisses several pending Petitions for Reconsideration and Petitions for Rulemaking that
asked, inter alia, the Commission to reconsider the adoption of iBiquity’s in-band, on-
channel (IBOC) system as the technology chosen for DAB transmission;"

This seems to quash any hopes for CAM-D or FMeXtra being put on an equal status with IBOC or for an open standard policy for digital broadcasting.

The only hope now, if I read this point on the FCC notice correctly, is for Kahn and DRE to directly work with CE manufacturers to incorporate their technology in future digital radios along with HD-R.
