This paper presents the results of Investigation of effects of Variation of Soil Conductivity on FM Signal
Distribution and Coverage Area in Ondo State. Sixteen radial lines were drawn on the map of Ondo state, and
measurements were taken in all towns and villages along all the radials. The signal distribution of two FM stations; a
high power transmitting station (OSRC, 18 kW) and a low power transmitting station (FUTA, 587W) were
measured using Geberit GE 5499 Digital Field Strength Meter and DBC BC 1173 Digital Signal Level Meter. The
various terrain elevations were measured using Etrex Garmin GPS and GPS 72 Personal Navigator. The soil
conductivity of each measurement location was computed from measurement taken with Kyoriotsu Digital Earth
Resistivity Meter using Wenner’s array method. The results showed that at both low and high transmitting level, soil
conductivity did not significantly affect the propagation of FM radio signals as it affects AM radio signals.
