Bob-Ob-The-Job: Your comment about WNDE's signal to the south was right on the money. Columbus is in the dead-center of the southern lobe and they sounded great. I agree that the noise level on 1260 is horrible these days, but in the 70's it was great because, for years, when WIFE (Indy's 1310) switched to night facilities, they just disappeared and WCSI signed off. so all you could do was hope the ionosphere was right for WLS or other distant stations. WNDE actually sounded a little better when the switched to the night array, because those 5,000 watts were now focused onto 2 lobes, one of them pointing right into Columbus. After a while you could hear Cleveland's WIXY or the Edmonton Alberta station (1260 is a Canadian Clear Channel), but most of the time it was WNDE, crystal clear.
Now the noise level is so high you can't pick WNDE out of the mess. There aren't that many class B stations with night time facilities on 1260, so I'd guess there are lots of daytimers who don't cut power at sunset. I've heard the Dickson Tennessee station (5KW days/18 watts nights) many times, especially when they are doing high school football on Friday nights in September, so you know we're getting the full 5KW.
Getting back to my earlier post about WOWO and the drop-in on 1190 in Dallas, it holds the record for being the 'most directional AM station in America'.
They are 50,000 watts with a 4 tower directional array during the day, but at night they have a separate transmitter site with 12 towers and a 5,000 watt transmitter. There's a joke down there that you can drive down the North-Central Expressway listening to it clear as a bell, but as soon as you cross the line to exit, you lose the signal. Here's a link to the night plot:

I was in Dallas several years ago and I visited their transmitter sites and talked to the CE. He said it was a chore keeping everything going. With the studios in downtown Dallas, the daytime x-mitter site with a Harris DX 50 and 4 tower array 20 miles northwest of town, and the nighttime x-mitter site 20 miles northeast of town with a 5KW transmitter and 12 towers, not to mention the auxiliary facilities. That's a lot of hardware to keep running.
There are a couple of questions I have about the WOWO downgrade:
First, 1190 is a US clear channel, and the FCC keeps both Portland Oregon and Ft. Wayne 'notified' as the dominant stations on that frequency. Meaning, even though WOWO is now a class B, stations in Canada and Mexico must still protect Ft Wayne. That's probably why they still get out so well in the southeast US with slightly less than 10 KW. My question, why does Ft Wayne remain notified?
My other question, once Ft Wayne was officially downgraded, there were several daytimers on 1190 who applied for night time facilities. I saw apps from Atlanta's 1190 and Kansas City's 1190 (both are daytimers). I believe WOWO finally became a class B in late 1999 or early 2000, which was 7 years ago, yet the FCC has yet to allow any station on 1190 to get/improve night time coverage. Why?
