Maybe you’re joking, NounosSon, but I’ll bite.
First of all, field strength is in uV/m, not uV. Field strength is not a voltage, but a voltage gradient. I’ve seen many misunderstandings and arguments about this point on Part 15 forums. Suffice it to say that the chart is supposed to be in uV/m, not in uV.
Where RadioBrandy uses yellow highlighting represents an excellent receiver with a sensitivity of about 2 uV/m to a monaural signal. Range is considerably less for stereo reception. Many receivers have much poorer sensitivity than 2 uV/m for mono. The lower field strengths shown in the chart would require a receiving antenna with gain, such as a Yagi.
