Low Frequency Communication and Navigation Stations

These stations often can be received by the Newport, Oregon receiver at night during winter months when the lightning-strike static level is low. Low-frequency radio propagation conditions vary considerably at different times of day and at different times of year. Noise levels also vary widely at different times, especially noise due to lightning. Lightning-caused static propagates over long distances in this part of the radio spectrum and often makes summertime reception of weak low-frequency signals difficult or impossible.
