Goodness, the nulling on that would have been insane even as the transmitter is quite a bit south of the FW metro.

I have seen other examples where a Class A AM station ended up reducing its licensed power after relocating its transmitter/antenna just a few miles. One is WBBM 780, also Chicago area. Are there ways to predict where blanketing complaints are likely to occur before spending the money on the engineering for the new facilities at the affected location?
For WOWO mentioned immediately above, wouldn't they have kept Class A status if they had taken that pattern given that the power would be over 10 KW?

I wish that there were some way to display the difference between the two on a map.
If it was already licensed as a Class B, they could increase it. I'd have to check on if that was filed before it was licensed at 9800 watts. It might have something to do with International designations. You'll see in applications a lot that there are a lot of stations designated Class A internationally that are operating as Class Bs. There are also a lot of allotments on Regional channels in other countries that are considered Class A. In Canada, most of those are vacated allotments.
You are correct regarding WTMJ's move.
I was simply wondering if its signal across the Milwaukee Metro was better, lesser or equal following its move. Certainly in places such as Green Bay its signal improved.
I suspect that if the multi node supercomputers used to design the three newer Downriver Detroit 50 kW arrays had been available when the six tower 10 kW WTMJ Night pattern was designed, it could have had a slight dogleg tower arrangement with more than 10 kW. The Day 50 kW pattern is four towers and only a shallow null toward what is now WAKY 620 Louisville, KY. The old three tower 5 kW array West of Milwaukee had a shallow null to the East toward Milwaukee. At the time it was designed, they had probably just upgraded from 1000 watts Night Nondirectional to 5000 watts Directional, and at the time, it wasn't determined to be a problem. The soil is mucky and loamy near the Union Grove site, with farmers' drains to prevent flooding for farming preventing them from being functionally wetlands, and very conductive, possibly exceeding the 15 mS/m shown on M-3 in some areas. They may also may have run into greater measured conductivity over Lake Michigan, which prevented them from using measured conductivity to allow the null to be shallower toward WAKY.

I heard that null first-hand driving between Columbus and Chicago last month. I admit I forgot all about there being a 620 in Louisville, but once I got a little south of Merrillville the phasing picked up on WTMJ. It was immediately recognizable that I was in a null and not simply losing the station naturally, so to speak.
Still, looping this back to WMVP, it sounded better at a much farther distance than how WMVP sounds in the some of the far western suburbs at night. I assume much of that WTMJ null falls over the lake or it's so shallow as not to terribly degrade reception in southeast Wisconsin.

Kind of like all the 1190s west of Fort Wayne (Kansas City, Dallas, Boulder until it downgraded, etc.) until you get to Portland and KEX, which is DA-N (a I-B under the old classification system) with a more basic three-tower setup.
Reputedly, the original nighttime pattern and power level of the station on 1190 in Kansas City were such that the station could not be received on the Country Club Plaza at night ... which happened to be where the station's studios were. I lived only a couple of miles from the Plaza and could hear that station at night, so this might just have been a tale.
If it's a housing development, it should be called Midland City Estates in honor of the most fantastic crime fighter the world has ever known...Chickenman!
Remember that Chickenman's given name was from across the Lake-Benton Harbor.
The WTMJ signal in the Milwaukee metro went from merely impressive to awesome when they moved the TX site from the western suburbs at 5kw to Union Grove (south of town) at 50/10kw. Unfortunately, however. The night signal at my location northwest of Chicago was dedgraded. Tough for this Packer fan to swallow. (But not as tough as the Pack eventually moving to WISN, which has no night signal here at all! LOL)
Packers are on their FM sister WRNW
Got it! Thanks. But just about as invisible most of the time for me. I listen online when I'm not able to catch them on TV. Or, if all else fails, I'm usually able to pick up WIBA (Madison), 1310AM.
WELLLLL
WIBA gets out quite well
Once I moved to NE Ohio from Florida [50+ years ago] I tried picking up WSUN out of the Tampa Bay area. Could pick it up rarely but usually wiped out by WTMJ. Listening one night in the 80s around 3-4 AM-ish, the overnight DJ was wondering if anybody was listening out in the boondocks. I called him and he was very surprised that he got a phone call and I was calling from NE Ohio. Nowadays, there's a religious station out of Knoxville that put an end of me being able to pick up WSUN/WDAE period and even though they have a null to the Northeast, I can still pick them up and for what it's worth WTMJ is almost non-existent at night nowadays.
Yeah. Surprisingly so. Even at my location about 80 miles to the southeast., it's listenable even usually at night.
WTMJ as become borderline unlistenable at my location at night. Used to be solid 24/7. I've never heard WSUN here morthwest of Chicago. CKRM (ex CKCK) from Saskatchewan sometimes blows out occasionally during winter months.
Unfortunately, WIBA's signal might not get out so well for much longer -- they have a construction permit to diplex with sister station WTSO. When they start transmitting from the WTSO site, WIBA will drop from 5kw day/night to 4.8kw day / 1.4kw nights, with tighter nulls to the southeast:
How's WRJN reception there in Crystal Lake?
Too bad iHeart isn't simulcasting the Packers on WISN, like they do in Madison on WIBA AM and FM.
Not anymore. As part of the FCC's AM revitalization plan, the "ratchet clause" was abolished. See page 15:
