FCCCurves

This little program finds signal strength values (in dBu) by using the FCC’s F(50-90), F(50-50) and F(50-10) tables (Sec 73.333.) Type in the power in ERP, antenna height (above average terrain) and the desired signal contour level and the program will give the exact distance to the contour. This program will also predict the signal strength of a station at a given distance from an antenna. FCCCURVES uses the actual FCC FORTRAN algorithms to produce the answers to your distance to contour applications, so the answers it produces are the same numbers the FCC gets in Washington.
