The beacon you heard on 50.075 is probably AA1OV. He's in DM41tw, or Sierra Vista, running 50 W. He transmits a CW ID every *4 minutes*. I can always here him at about 559 just on a vertical, here on the NE side of town at DM42pg. With a quick check today, although I hear AA1OV, I don't hear any other signals on the band.
