It's actual low frequency modulation on 1190, complementary in each sideband (so you don't hear it unless you're receiving one sideband only). I'd doubt you could hear it at night since there are so many other stations competing for the frequency, unless you're really close. Whether it's WOWO or not I can't say, but it seems to be most likely, since it's the only 1190 station really in competition for Central Ohio in the daytime. WFAN 660 had the same sort of thing for a couple of months last winter, only it was a phase modulation introduced by their broken power supply, inaudible unless you were hearing only one sideband.

Ok. There was a lot of discussion on some MW boards about the WOWO
IBOC this past week. Assumed it was IBOC going through some adjustments there. I have heard is described differently in terms of what it sounds like. I have listened to some clips and it is hard to describe. |

This sounds more like a low bandwidth digital subcarrier. I take it back. It's an on-frequency artifact of IBOC after all. WCOL 1230 Columbus (or whatever they're calling it now) has the same deal, a diesel engine idling sound when received either LSB only or USB only but no sound when both sidebands are received. It has IBOC, and in fact I spend a fair amount of time nulling its splatter into 1240 away to hear Zanesville Ohio. That 10 kHz off-channel splatter is the obvious component of IBOC. I hadn't noticed this on-channel artifact before. So it's a way to tell who is the IBOC splatter source : who has the diesel engine sound when received LSB (or USB) only. -- Ron Hardin On the internet, nobody knows you're a jerk. |
Zanesville,Ohio.Isn't that were they can go to the bridge and turn
right? cuhulin |

When Leonard sued and stopped AM stereo, AM still had over 50% of the audience. By the time the legal issues were solved, AM had half that and could never recover. Analog AM stereo, in the late 70's, could have helped keep the balance between AM and FM. The legal machinations stopped this. |

Analog AM stereo, in the late 70's, could have helped keep the balance between AM and FM. The legal machinations stopped this. Horse hockey. I'm not saying Leonard's suit didn't hamper the reality of AM stereo, but if it had become a mainstream thing, "stereo lo-fi" would have never held it's own against "stereo hi-fi" (FM). Especially when the FM stations went to virtually ALL types of programming during the seventies. Prior to that, FM was classical, alternative (including what was known as "AOR") and as a vanguard, country. Nobody loves good old AM radio like I do, but there is no accident to the fact that AM radio today is very largely 24 hour news, sports, and talk radio formats. That had a whole lot more to do with changing technology than it did with Leonard Kahn. Classical music will always sound tremendously better on FM than AM because of the frequency bandwith. Classical music (as one example) in AM stereo will sound like stereo AM radio broadcast of classical music. A pale imitation of stereo FM broadcast of classical music.
