I'm still skeptical about this formula:
Field Strength (uV/m) = 10 ^ ( (107 - |dBm| ) / 20 )
Is this valid? I saw this formula somewhere and jotted it down.
_______________

uV/m = 10^[(dBm - G + 20*log(F) + L +75)/20]

where

dBm = signal level at receiver input in dB with respect to 1 mW
G = receiving antenna gain in dBd
L = line loss in decibels
F = Frequency in MHz
