AM Frequency of the week: 760

That's interesting. Jackson is farther west than Toledo, but not all that much, and certainly not enough where there should be that big a difference in the reception of Chicago stations. Of course, I was in Toledo in the late 1990s so maybe things had changed. I just know they are much easier to hear in Findlay and Lima than Toledo, both of which are roughly the same distance from Chicago (oddly enough, I used to struggle getting WOWO in Toledo as well when it came in much better to the south).

When I was in metro Cleveland a couple of weeks ago, WJR was almost as strong as a couple of the Cleveland signals 10-15 miles away. You had lightning interference as you would expect in the summer, but it came in very well. If JR still used HD, you could probably hear it there. It rated in the Cleveland book as recently as 5 years ago with as high as a .5.
 
...update...now KFMB decides not to proceed with their application to reduce to 10kw DA-nights, so they'll stick with their 50kw licensed night power. This article, however, makes it seem like they've been at lower power nights for a while for some unknown reason, and are preparing to raise power *back* to 50kw. Anybody know what's up with this?

San Diego’s KFMB/760 will keep the 50,000-watt night signal, after all.

...in a July 26 hand-delivered letter, Midwest TV’s attorney John Logan asked for “the withdrawal and dismissal of the construction permit application for a reduction in nighttime power.” He said KFMB “plans to return to full, licensed operation [at 50-kw] within the next few days.” Talk KFMB has an unusual facility – 5,000 watts daytime, but 50,000 watts at night.

Completely agree. As I said on the first page of the post, WJR is practically a local in Conneaut, 65 miles northeast of Cleveland (CKLW is equally as strong at all hours of the day and night). WJR is much stronger there than here in Columbus, which is a comparable distance from Detroit as Conneaut. Although Lake Erie is fresh water (insert joke here), I can't help but think the lake helps those two signals along.
 
Doug Vernier's MW propagation software shows WJR to have the following groundwave fields in these locations...

Conneaut (ZIP 44030) 0.95 mV/m
Cleveland (ZIP 44105) 2.4 mV/m
Columbus (ZIP 43026) 1.0 mV/m

Receiver performance and local noise levels in those receive locations will affect how noise-free those fields are.

I could hear WJR's daytime groundwave on a stock radio in a Volkswagen Beetle back in the mid-1960s when driving from Detroit to east of Pittsburgh at Somerset, PA.

Interesting, and thanks for those numbers. WJR is decent in parts of central Ohio, obviously better the farther north one goes, but not a powerhouse. Am a bit surprised that Conneaut is the lowest of the three purely because of what I've heard.
 
OTOH, there is a major azimuth sector where the radiation from CKLW toward parts of Ohio is much less than from the non-directional pattern radiated by WJR.

An example of this is that in Cleveland, CKLW has a daytime field of about 1.3 mV/m while WJR has a field of about 2.4 mV/m
 
I remember wondering why CKLW gave the temperature in Toledo Days and Cleveland Nights back in the 1960s. Didn't know the patterns were that different then. Very unusual design. Carl Smith most likely designed it.
 
I don't remember them doing Cleveland and Toledo at different times of the day (though sometimes they'd throw in Sarnia or somewhere like that). They'd have had reasonably good signals into Toledo and the western half of Cleveland both day and night.


That CKLW southwestern lobe was pointed right at me. When night pattern hit that lobe went away to protect XEROK.

As close in as Sandusky and Put-in-Bay, CKLW's southerly null is very noticeable. Sounds great in Toledo and up in the northeast corner of the state, but not in the middle.
 
Toledo Fields of WJR and CKLW

For Toledo ZIP 43606:

CKLW has about 14.8 mV/m Day and 2.2 mV/m Night.
WJR has about 14.3 mV/m Day and Night.
 
43606 is the zip for my college alma mater, and that's exactly how I remember it. No discernible difference in strength daytime, and while CKLW was (and is) still quite listenable at night in Toledo, there's QRM if you listen closely.
 
I had posted this on the Detroit board,
but I think it might have been more appropriate here.
Any guesses?
 
In Montville CT:
760 WVNE in Leicester Massachusetts, it's a 25kw Religious station that comes in fairly week despite being 70+ miles. It's a daytime only
At Night: WJR from Detroit, which seems to be received everywhere on the east coast. Some night it comes in better than others but it's always has at least a decent signal.
 
WJR Groundwave Coverage (re-posted due to "lost graphic" in 8/17/17 1st post)

Here is a plot of the 150 µV/m daytime groundwave contour of WJR, including the effects of earth conductivity for that region.

It includes parts of the states of Michigan, Ohio, Indiana, Pennsylvania, New York, and W. Virginia as well as part of the province of Ontario, Canada.

Here on Cape:

Days: WVNE 760, Leicester, albeit very weak.
Night: I *think* it's WJR, but it can get pretty muddy.

When I lived in STL:

Days: Muddy KCCV 760, Overland Park,KS. I barely could get it, but it did exist.
Night: WJR easily.
 
Yakima WA
Daytime - nothing
Nighttime - Usually a mix of KFMB San Diego (News/Talk) and KDSP Denver (Sports). Once in a great long while, CFLD Burns Lake BC (Adult Hits - 'The Moose') will mix, they used to be common in western WA...not here! And yes, a few times during the winter I'll hear WJR Detroit (News/Talk) but it doesn't come in every night. When WJR is in, the conditions are really good to the east.

Wanted...
KGU Honolulu (Business Talk - in my dreams?)
XEABC Mexico City (Spanish News/Talk - this must be easier than KGU...in fact I did hear faint SS on 760 last September during aurora...now if Mark Levin and KFMB would've faded away)
KTKR San Antonio (Sports - 50KW daytime should be well more than enough to hear this in the pre-sunrise period, maybe on a good morning in the near future. WOAI is common at night and when KKYX is on day power at night, they are EASILY noticeable under KNBR.)
