Calculation program: Field Strength Pro
- Field Strength Pro Ver.1.0
- Notice (Field Strength Pro Ver.2.0)
- Field Strength Pro Ver.3.1 (Beta version)
Field Strength Pro Ver.1.0 is a free software to calculate Expected Field Strength
Value. 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 4000 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.

Beta version is not offered now.
Field Strength Pro Ver.3.1 (Beta version)
Field Strength Pro Ver.3.1 calculates Expected Field Strength Value of multi-hop sky-waves and ground-wave at a fixed point. It 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.
