8/25/08, 0100 UTC (approx.), during WNKR relay on 6925 AM (low power signal), UNID transmission in 6925 USB with yodeling song, a long pause, then some sound fx with pitch/speed shifting/flanging, and V2 Spanish numbers YL (apparently recorded off-air, badly modulated - note to Arnie...). SINPO - 31235 (extra credit for amusement value). (N. Central TX)
