AM Frequency of the Week 640

Can we stop going off topic?
Besides being about 640, this is about a clear channel and the reception of stations on those frequencies at great distances is not unusual. So comparative reception situations with other clears is most appropriate.
 
No real harm in doing so on a frequency thread like this. Not much to comment on once everyone's reported what they're hearing on 640, so why not exchange a little MW DX chatter while waiting for additional loggings?
A well explained reason why Radio Discussions allows great leeway in taking subjects onto interesting side roads and alternate highways.
 
In my travels to many corners of North and Central America the most consistently receivable signals have been 650 WSM, 700 WLW, 1040 WHO, and 1120 KMOX. But as Mr. Eduardo said, the two reaching the most population may be WHO and KMOX due to their location and favorable ground conductivity.
 
Is there any reason WJR (760) hasn't been mentioned? It pounds into New England at night, stronger than WHO or KDKA. Is its overall range limited compared to the other clear channel stations discussed here so far?

Down here in Houston, XEABC is almost always dominant on 760 with WJR in the background. IIRC in California, San Diego usually owns 760.

KOA 850 has to be considered as well. I've heard it in the south (central Florida, despite stations in Gainesville and West Palm Beach), the west (Los Angeles) and it's a nighttime regular here at home (Chicago area). It's also audible on the Hawaii SDR. Again, it's the central location.

The same is true up here in the northeast part of the State, Jim. XEABC is awfully hard to null, but does make for some rather interesting listening when they go to playing English language hits of yesteryear. Nothing says broadcast from Mexico like Radiohead's "Creep" being sent out over the airwaves in all of its unedited glory.
 
I believe at one time it was determined to be WHO in Des Moines: high enough frequency for better night skywave and near the center of the US. KMOX would also be a likely candidate for this distinction.
I would agree. it's very close between these two. WHO has a slightly better central location , but for whatever reason, KMOX seems to have a more robust signal in more locations. At least that's my experience in nearly 40 years if travel around the U.S. and Canada.

I also share the viewpoint that we should take a broad view and permit secondary topics. In my opinion contrasting KFI's coverage with that of other "clears" may be a sidebar from the original topic But to my mind, there's still a connection there. Even if perhaps indirect.

Agreed. Over the years, KMOX has been more persistent in hanging around in the morning than WHO at my southwest suburban Chicago home. KMOX is about 50 miles closer, but a bit higher up the dial. About 15 miles south of home, KMOX can be around all day long, as WLW is in my driveway and sometimes in pockets of the house.
 
I see from Wikipedia that KTIB became "97.9 La Calle" April 2022. That would explain why I haven't noticed them in a while. When I hear Spanish on 640 I've assumed it's Progreso or one of the 2 regular Mexican stations!

Thanks for the programming update. I’ve never heard KTIB from San Antonio. XETAM “Romántica” in Cd. Victoria to my S/SW and R. Progreso to my SE are the only Spanish-language regulars these days, although I’ll occasionally hear XENQ in Tulancingo when XETAM fades. (This is all with splatter from local 630 KSLR.)
 
Rocklin, CA

Daytime: Splatter from KSTE
Nighttime: KFI Los Angeles with a weak signal

Vallejo, CA

Daytime: Nothing
Nighttime: KFI Los Angeles
 
True, but the absence of WBOW cleared the way for WMFM to move south to Chicago. Otherwise, there would have been interference to the WBOW signal in fringe areas.
The FCC had an auction for 640 in Terre Haute. Birach owned WMFN in Zeeland MI. He won the auction, shut down the Zeeland frequency, moved the Terre Haute license to Peotone with their current power, with no interference problems from Zeeland. IIRC.
 
Looonnng time ago, off a Zenith console with the Wavemagnet antenna in the back that I never figured how to adjust, I finally heard KFI back in Queens NYC. Most of the time it was Cuba, after CBN signed off. Never knew how to null a signal then, y'know?
I vaguely remember the KFI QSL being in the form of a tall blue-and-orange postage stamp. Again now, it was long ago, but the recall now was of TWO towers in an orange harvest field on the stamp. Can anyone here, uh, verify if that was so, or if I need a cognizant competence exam ?

That was an EKKO stamp, left over from the later (post-FRC) 20's and 30's when "everyone" was a DXer and people collected those things like postage stamps or baseball cards.


Here is an example:
