Freeware: Field Strength Pro
Latest version: Field Strength Pro Ver2.0
Field Strength Pro Ver2.0 is a free software to calculate
Expected Field Strength Value of multi-hop sky-waves and ground-wave at a fixed point. Field Strength Pro is applicable for calculating
field strengths of LF/MF waves for frequencies from about 40 to 500 kHz
over ground ranges up to 16000 km. Field Strength Pro is primarily based
on the wave hop method in Rec. ITU-R P.684 for the sky-waves and on Rec.
ITU-R P.368 for the ground-wave.
