General exam question G0A12
Subelement G0, ELECTRICAL AND RF SAFETY· Group G0A · 47 CFR §1.1307(1)(b)(3)(i)(A)
What stations are subject to the FCC rules on RF exposure?
- A.All commercial stations; amateur radio stations are exempt
- B.Only stations with antennas lower than one wavelength above the ground
- C.Only stations transmitting more than 500 watts PEP
- D.All stations with a time-averaged transmission of more than one milliwatt (correct answer)
WhyAll stations with a time-averaged transmission of more than one milliwatt are subject to the FCC rules on RF exposure. Per 1.1307(b)(3)(i)(A), the FCC's RF exposure rules apply broadly, to any station whose time-averaged transmitted power exceeds a very low one-milliwatt threshold, which in practice covers essentially every amateur station, answer D. Amateur stations are not exempt (ruling out A), the applicability isn't limited to antennas below one wavelength or to stations running more than 500 watts, so B and C are also wrong.
