AM Frequency of the Week: 570

Back in the 1960s, one thing I always did when I visited the NWC/ORD Area, was to look at the newspaper radio station listings, especially in The Chicago American, which had a complete and very readable listing of all AM and FM stations. I remember that WILL 580 was listed, and one year, a new one, WYLO 540, which I had to find a radio and check out immediately. I was surprised that it came in very well, later discovering that it was just 250 watts, on a clock radio. I had the newspaper clipping for decades, but I don't know if I still do.

Is WYLL the modern day WAUK? I heard WAUK changed from ESPN to talk.

I should have mentioned that WILL did some advertising in Lafayette, IN (mostly buscards) even with WBAA there. Reason was WBAA had stopped carrying Morning Edition and All Things Considered for a time.

Didn't Purdue University just sell WBAA? I'm pretty certain that they did, but I'm not sure if the deal is closed yet.

Yes they did, basically merging it with Metropolitan Indianapolis Public Media, owner of WFYI, Indianapolis. Lafayette will still have some local staff.

I'd have to hear it to make an educated guess. If what icybluelake is hearing is a continuous tone, it's probably a het.

If it's a sound that's sort of like the blade of a saw being pushed back and forth, it's a "wobbler". Someone here more knowledgeable than me can explain how those are created.. Anyway, several months back a "wobbler" on 870 was being widely heard, and the most common theory was that the noise was emanating from Cuba. That line of thinking stemmed, in part, from the noise being strongest on the Key West SDR. I actually heard it a couple of times when I was at our beach location near Pensacola this past February. Although then the sound was well in the background of WWL.

When the "wobbler" was first heard about 10-15 years ago, it turned up on Channels that the Cubans might have an interest in jamming. But 870 is a frequency that Cuba shouldn't have any objections to. And WWL has a null 24/7 in the direction of Havana.

I think it's a het. That was my first reaction but I didn't feel confident in saying so. It's not the wobbler -- it's a continuous tone. I think it's there both day and night so it's unlikely to be the effect of WWL. It's very consistent from day to day and I'm wondering why now and for the last few months when I don't think I've heard it before on 570.
 
From NW San Antonio:

Day: I hear a weak but intelligible KLIF with XEBJB underneath it. There's a bit of splatter from 580 XELDRA.

Night: KLIF is still strongest and usually on top, but both it and especially XEBJB are subject to some skywave/groundwave cancellation. Occasionally XETD "La Patrona Escuinapa" in Tecuala will pop up. I logged it for the first time recently, but I may well have heard the station in years past thinking it was XEBJB when the latter played regional Mexican music. Aiming SE, I sometimes hear the time pips from Radio Reloj in Cuba.

Sunrise: XETD is stronger and takes over at times. Both it and XEBJB sometimes cover up KLIF for a while until skywave is gone.

DX/Retro: One-time loggings include KWML in Las Cruces, NM, just after sunset about 8½ years ago and WNAX at sunrise six years ago.

WAUK is now progressive talk on 540 with a translator on 101.1 FM (250 watts from an 1100 foot tower....(nice!). Apparently, the previous sports format is now exclusive to full signaM ilwaukee 94.5 FM. WAUK is now identifying itself as "Waukesha", a large suburb, about 20 miles west of downtown, Milwaukee, but the COL is still "Jackson, WI". Branding is "The Sha 101"
 
From the southwest suburbs of Chicago, an all-X listing for 570 over the decades:

WKYX Paducah, Ky. (500 watts night)
WAAX Gadsden, Ala. (500 watts night)
WNAX Yankton, S.D. (5 kW day)

I didn't keep a very detailed listing way back, but WKYX and WAAX have to have been heard with WIND off. I don't sit on 570 often because WIND is relatively close and bombs in.

Thanks for the tip on XETD. I've heard music under XEBJB/KLIF a few times and wondered what it was. XETD isn't listed on mwlist or the IRCA Mexican Log, but the Wikipedia article says the AM is still on and their website mentions 570.

WIND was off the air for a time in late 1985 as I recall, just before the Spanish format
 
Brought up a memory from the past. I am in Fort Worth, TX and the week after Thanksgiving 1990, the former WFAA-570 (Newstalk 57), after 3 failed formats in 6 years - rock as KRQX in AM stereo, oldies as KLDD, and simulcast of an FM "warm music" station as KKWM, finally sold itself to KLIF "the Mighty 1190" which would take over the 570 frequency 11/29/90. But for 2 or 3 days before that, 570 was off the air and driving home around 45 minutes before sunset (4:45 p.m. CST) WNAX 570 AM, Yankton, South Dakota 700 miles away was coming in like a regional channel 90 miles away. It was a jumble of stations by sunset. The next day, I ran out to my car during a coffee break at 2 p.m., and still was getting a solid signal, obviously ground wave.
