Modification of the LF transmit site at dixon to support RF propagation and ionosphere research

There remains significant interest in understanding the spatial and temporal effects ionosphere disturbances have on radio wave propagation. In particular, RF propagation in the low frequency bands from 30 to 300 kHz is susceptible to ionospheric variations caused by volcanic and seismic activity as well as ionosolar eclipses. These variations modify the Earth-Ionosphere waveguide resulting in changes to the amplitude and phase difference along different transmission paths. The goal of this paper is to determine the feasibility of using an existing LF transmitter to support ionosphere-radio wave propagation studies in the future.
