AM Frequency of the Week: 1140

Merry Christmas Everyone....or to paraphrase Frank, if you celebrate differently, here's hoping you enjoy your holiday and the Holiday season as a whole!

This week, as visions of good DX dance in your head, the question is what are you hearing these days on 1140?

Here 40 or so miles northwest of downtown Chicago daytime it's splatter from WISN. On a really good day with a really good radio, WVEL 5kw ND from the Peoria area can sometimes be heard and identified.

Nights, it's all WRVA. Alone and with a good signal. I've never been able to identify anything else on the channel at night, although at sunset after WISN powers down and WVEL signs off, I've heard KSOO a few times.
 
Where I am in the near north Chicago burbs I get light splatter during the day from WISN. At night all WRVA with a very good signal. I can't remember hearing anything else at this location.

I think you may be a little too far east to hear whatever might be left of WVEL from underneath the WISN splatter. Although it's probable that when i've heard WVEL, there's some daytime skywave going on. During my college days in southeast Iowa, they were a daytime regular (as WSIV) with a weak signal and a format that was a knockoff of Chicago's WAIT. "All Mantavoni, all the time"....or so it seemed!

It's possible I may have heard it back in the day, but as of right now I'm hearing nothing on 1140 this afternoon except light splatter.
 
Cuba used to have"buzzsaws" all over the island on 1140, especially around La Habana, but I think that now they put a lot of their domestic network stations on 1140 (as well as on 1180, 670, 710, and 1210).

As I recall they were on 1142 to jam WQBA...

Yes, it was a sawtooth wave transmitted upper sideband, and I will never understand why it was on upper sideband only.
Remember, all receivers back then were analogue, so a listener could tune down a bit and listen in the clear.
I think they ran a loud, low-pitched sinwave on 1180, maybe also USB.

I wonder if O.G. Villard's small anti jamming antenna could be adapted for such situations. I would think that it would have to be a lot larger for AM BC for the much longer wavelength.

O.G. Villard, Jr. had fascinating inventions, and fascinating family and professional connections. I talked to him once on the phone at Stanford, I think it was back in the early 1990s. I wish that he and John Kraus were still around and still inventing things. An anti jamming antenna becomes a DX antenna. And DX antennas extend the number of normally received stations greatly. When the TV industry and FCC were telling us that DTV would have the same range as analog, and I bought a converter and tried to DX, I knew that it was false, because I was a DXer. If you couldn't get a local consistently, we knew that it would be hard to DX. Not impossible but much harder.

Daytime - local station WBXR, Hazel Green, AL. Nighttime is a mishmash of signals but mostly WRVA. BTW, WBXR has great coverage in its directional southern lobe and have heard it in FL during critical hours.
 
A couple of years ago one morning when local WBXR was off the air in Huntsville AL, WLOD came in surprisingly very good here.

I am not familiar with his design, but most anti-jamming antennæ are effective for countering single jammers, not multiple ones from multiple directions.
Countries with large resources will often use several local groundwave jammers in population centers and skywave jammers to cover large areas.
