Old Great Lakes Low Frequency Marine Beacon List

During what decade were these beacons activated?

By 1996 all of these beacons had been decommissioned by the USCG.

Normally radio direction finding (RDF) is not a topic for this site, but
the list is peripherally related to radio communications on the Great
Lakes so it has been included.

Andy Robins, KB8QGF, extracted this list from a much larger beacon
list compiled from multiple sources by Dave Tomasko who granted
Andy, permission to submit it.  These gentlemen DX beacons of all
types, and are members of the Beaconworld organization.
