WIZF signal problems

Does anyone know what's going on with the The Wiz's signal. I was visiting family in Cincinnati over the holidays and noted the station became full of static coming into Walton and never improved much after that. However, Mojo 100.3 came in just fine.
 
Hmm.. I am in Dayton and it is very static as well. Usually comes in much better. This may be a sign of them getting HD. This is what happened to Channel 94-5 here.
 
I have noticed that their processing sounded strange this past weekend. The audio sounded muffled no high end frequency response at all. I didn't hear any static or decrease in signal though.


I'm not sure if they are running IBOC HD or not since I don't own a HD receiver.
 
It seems odd given that they supposedly increased wattage and that Mojo puts out less power than them.

Then again, does The Wiz really need to put a signal into "Deliverance" land where few people would listen to them anyway? <half joke, half serious>
 
They have been running Iboc for a long time. I got my HD radio last January, and I'm pretty sure that they were already on.
 
I noticed some problems with their signal this past weekend driving on I-75 thru Warren county (around Franklin)...WSGS in Hazard KY was overwhelming their signal for a time until I was past Middletown. Typically the signal goes all the way into south Dayton until the CC tower near Dryden Rd bleeds over everything.

As a curiosity, why would installing HD have anything to do with a weak analog signal? The HD bands are not on the same frequency as the analog FM signal. They're two separate transmitters.

Maybe they forgot to pay their tower rent.
 
HD most certainly affects analog signals. The generic name for this type of transmission scheme is IBOC -- for In Band, On Channel.. and the whole point of it is the digital signal can be piggybacked onto an existing station frequency.

That said, a station with this system wouldn't be interfering with itself. As you get farther from the station, the digital signal, which is much less powerful than the analog, gets weaker just as the analog channel does, so the digital modulation is never enough to hurt the station's analog signal.

The same can't be said of another station's digital signal. The digital portion of signal on a neighboring frequency in a neighboring area could curtail WIZF's coverage in that direction. That's probably the number two complaint of critics of HD-Radio. (Number one is probably the very short range in digital mode.)

But people simultaneously reporting problems with Wiz's signal in a couple of different directions could indicate a different type of problem.

Quite correct, I was inaccurate technically. Separate exciters, not transmitters (due to low power requirements). However, the signal degradation comment is correct and is what I intended.

As for intermodulation, Clear Channel in Cincinnati just so happens to have frequencies that intermod on neighboring competitor's stations... go .8 Mhz up or down the dial from their properties and see what you find. It's not an accident. Also, intermod is not intermittent; it's a constant, so for it to have any effect on the WIZF signal, it would have had to be a new station on an adjacent frequency.
