"ESPN 690" mentioned a few times but no discernible station ID call letters, Sports talk @ 05:12 UTC , commercial block promoting "Japanese Whiskey" then back to the syndicated talk show hashing over all the NCAA conference championship football games. Thinking this is probably WOKV out of Jacksonville but I've never picked them up before and their broadcast pattern doesn't lend itself to southern Wisconsin.
Maybe WJOX out of Birmingham AL. ?
