I used to get WHO regularly for many years here in Houston. However, when KEYH 850 went 24 hours along with Cuban interference I could no longer receive it. Back in the late 1960s, Mike Hoyer did an all night country music show, which I would hear a lot. At that time, there were three AM country stations in Houston: 650 KIKK, 920 KTLW (Texas City) and 1070 KENR; all daytimers.
You had do a lot of DXing to hear country music at night around here. 1050 XEG played country music at night with a show called "Country Music Time." The music was good, the announcer was just that, an announcer. Sometimes, we would get a good signal from WSM and of course, WBAP, which was country with Bill Mack after 11PM CST. 1130 KWKH was another source for country at night.
Sorry, I digressed.
