Sea and air LF communication and navigation stations

Low Frequency Communication and Navigation Stations

Most of these stations can be received by the Salt Lake City receiver at night during winter months when the lightning-strike static level is low. (Note: The Salt Lake City receiver has been moved to Newport, Oregon. This page has been retained for the benefit of Salt Lake City area visitors.)
