Topband: Mystery Signals on 160

[Lee K7TJR]

     On occasion I hear the triple beep signals here on the low end of
 160. I too believe it is a Hyperfix navigation system. Hyperfix has
 several modes and therefore not all systems sound alike. I believe it
 to be coming from the Bering sea area. It definitely arrives hear
 toward JA as well. The loudest one here is on 1813.3 and another
 around 1814. Sometimes I have heard several.
