Early today here in NW San Antonio, starting at 00:45 CT, I logged what I presume was KSGL in Wichita, KS, on 900. I was hearing a weak signal in/out with adult standards music in an E/NE partial null of XEW.
Songs played were by Betty Hutton, Frank Sinatra, Martha Tilton, Mel Tormé, Ethel Ennis, Pete Fountain, and Harry James. There was occasional DJ talk between songs, but it was too down in the mud to understand; however, I was able to make out some "Great American Songbook" references.
KSGL is the only station I can find on 900 with an adult standards format. According to its website, it has mostly Christian talk programming during the day but "Music You Remember" overnight.
If this was indeed KSGL, it was probably on 250 watts day power rather than its regular nighttime 28 watts. The distance from me would be 565 miles.
