nothing mentioned about 3 meters and 100 milliwatts, curious!
Here are some numbers if this operator claimed to be operating under Part 15.219…
With 50 ohms total coil and r-f ground loss and 75 mW of transmitter output power applied to a resonant, base-fed, 3-m radiator at ground level, the maximum inverse distance field at 57 meters would be about 2,220 µV/m — which is only about 10% of the field measured by the FCC.
So in order to produce the field measured by the FCC for these rather typical coil/ground losses, this system used either more transmitter power, an elevated antenna, or possibly both.
So the FCC had their choice of rules to apply, but the operation wouldn’t have been compliant in any case.
