AM Frequency of the week: 750

This week, let's move down the dial to 750. What do you usually hear at that place on the dial?

Here in the far northwest suburban Chicago days, it's a fair-good signal from WNDZ, in far southeastern suburban Chicago. 15kw aimed in my direction. The signal seems weaker than it actually is, because it's sandwiched between two local blowtorches, WGN and WBBM.

Nights, WSB takes over. Solid and generally alone, although sometimes there's an unidentifiable signal underneath.

In the near north Chicago suburbs during the day I hear a good signal from WNDZ. At night a good WSB with sometimes a South American station weakly underneath.
 
From Houston - blank daytime with splatter from KTRH depending on where you live. Night, WSB with Spanish language stuff underneath.

Lubbock, TX in the early 00's with a five foot loop - WSB daytime with deep fades.

Daytona Beach FL in the early 90's, weak WSB daytime. strong WSB night.

Melbourne / Palm Bay FL in the late 90's - blank daytime. 80 miles made a lot of difference on WSB. It looks like 400 miles is about it for their groundwave. Still an impressive station.
 
Here around Columbus, Ohio, nothing during the day and all WSB at night, with varying signal strength.
When I lived in the Houston suburbs, WSB was listenable from my location (League City, southeast of downtown) with a turn of the radio because KTRH's very powerful signal came from north-northeast of me and allowed me to somewhat null it out.
I rarely hear the Caracas signal this far north, but it has happened from time to time during auroral events. I once heard it completely blanking WSB on a visit to Panama City, Florida in 2004.

That is an amazing feat in Houston daytime. I will have to try it, I am far enough from KTRH that I can null them completely. I don't doubt it could happen daytime under the right conditions, but the ground conductivity is poor compared to Lubbock - which explains the 1000 mile daytime reception with a large loop from there. It would likely take a large loop from Houston in spite of being closer to Atlanta.

Maybe - Caracas is the Spanish language station under WSB at night. I was on a cruise one time in the Carribean, and Caracas 750 was a monster, coming in all day on the ship when I went on deck. Often, it was the only station on the dial.

Sorry, I should have clarified that any WSB reception I had was at night!
 
Days, 750 is covered by our local on 740. I'm under 5 miles from the 740/WNOP transmitter, and they send a lobe my way. Wouldn't be anything to hear anyway.

Nights, I can null WNOP & it is all WSB. Never heard another station.

This should be an interesting frequency for someone at the right spot in Cali. Potential for a mix of 5 or 6 stations.

Maybe not for pianoplayer88key, what with KFMB on 760.
 
In eastern Iowa, daytime: often nothing, but sometimes WNDZ from northwest Indiana. Usually if I hear WNDZ, it's faint. One time in the last year or so, I heard a station that sounded like religious programming (in English) and thought it might be KMMJ from Grand Island, NE, which would be kind of a daytime catch. But I didn't hear an ID.

Nighttime, it's all WSB. Can't recall hearing any other stations at night on 750 other than WSB.
 
I have an RFI issue on this frequency, most noticeably when aiming the antenna NW/SE. It occurs in all portions of my house. I haven't tried turning off all power to pinpoint the source yet, but if I go out in the driveway or front yard at least 15 feet away from the house, the RFI disappears.

That's a moot point during the day, though, because IBOC trash from KTCK, 760 - The Ticket, makes 750 completely useless.

At night I get either a weak WSB or a weak XECSI, "Extasis Digital," in Culiacán. The latter is sort of like a "Jack FM" that plays only '70s and '80s hit pop/rock but with a much bigger playlist. Both stations typically have deep fades - one will be in for a long time, and then the other will take over while the other one drops out. I'm surprised at WSB's weak signal here because when I used to DX in my youth back in the late '70s, WSB usually had a fairly strong signal.

Around sunrise when WSB is totally gone, XECSI gets stronger and a lot more steady. Also, when away from the RFI around that time and aimed NW/SE, I've heard a faint station playing regional Mexican music that I've yet to ID. One time in April around sunrise, I snagged XEURM in Uruapan, a "Los 40 Principales" station.
 
Does KTRH ever give WSB any interference at night in San Antonio? The few times I have been to SA, I was never in a position to DX at night. I imagine SA is out of KTRH's cancellation zone.

Not at all. I get KTRH day and night, but it's never strong enough to cause interference on 750 or 730.
 
Here in Denver I've gotten the following at 750:

WSB - Atlanta, GA
CKGB - Timmons, ON
KMMJ - Grand Island, NE
KOAL - Price, UT

Mostly I get splatter from AM 760 KKZN - Thornton, CO
 
KXTG day (very weak)
Sunset - KERR Polson MT, KXTG
Night - mostly KXTG, but can also hear KOAL Price UT and CKJH Melfort SK on occasion
KHWG Fallon NV is rare, but when they forget to switch to night power, they are STRONG.

Would like to hear - KMMJ NE, WSB GA

Here in southern Pennsylvania ,WBMD out of Baltimore Maryland,a 1 kw daytimer,produces a strong signal with excellent coverage.Nightime it's WSB Atlanta.
 
I'm almost in the line of sight of WSB's transmitter, office being about 4 miles away, so it's WSB 24/7 for me!! Obviously the same at my house, which is about 10 miles from the transmitter. However, WSB's nighttime convergence / cancellation zone, because of the poor ground conductivity, is relatively close in, about a 60 - 175 mile radius of Atlanta. Beyond that, WSB is pretty much a given in much of the eastern half of the US!!

When I lived in SE Michigan back in the mid 80's, WSB was surprisingly strong at night, even with splatter from WJR 760. For whatever reason, WJR isn't nearly as strong in the Atlanta area as I've found WSB to be in the Detroit - Flint area.

As one who travels on business quite frequently, there have been very few places east of the Front Range of the Rockies where WSB was totally absent.
 
I've heard about the ground conductivity issue with WSB - but reception was reliable during the day in Daytona Beach with an un-modified, un-aided GE Superadio 2.
 
about 35 miles from WSB, I get WSB 24/7 of course. But many nights there is spanish under it. Also, some nights I get the selective fade from ground-wave/sky-wave cancelling each other out.
 
I suspect it is ground conductivity at the receiving site, not the transmitting site, that is the problem. In an area of very good conductivity - Lubbock, TX - I had no problem receiving it with a five foot loop during the day. I did this at different times of the year. Of course reception of that type is subject to deep, long lasting fades, but WSB was definitely there. I heard multiple ID's and Atlanta commercials.
