The first one that came to mind, w9wi and dxho, was WMMN In WV. I've heard them at various times on Long Island and in Norfolk in the 60's, and here in NEPA in the 90s.
I presume that dxho checked and found WMMN listed as Fox sports, not ESPN.
But Radio-Locator also lists WMMN as being 200 watts at night. Huh? Every old NRC log I have -- admittedly old NRC logs -- lists WMMN as 5000 watts day and night. Considering the possibility that Radio-Locator is incorrect listing them as 200 nighttime watts, might their situating of WMMN as Fox sports be (as it were) off-base, too?
