   Mike and others,
   Those signals are NOT fishnet beacons. They are as one here said a version 
of a navigation system similar to Hyperfix. The reason you hear three "dings"
Is that there are three transmitters for each one that transmit in sequence and 
the electronics aboard ship measures the time of arrival for each pulse 
providing harbor navigation.
  How do I know this, I have heard them from the NW  here in OR many times and 
looked them up years ago. There have been at least two discussions about this 
here on top-band reflector over the years. And as mentioned they NEVER ID. They 
are also low power.
Mike I would suggest you Google Hyperfix.
   Lee   K7TJR  OR
