- A.Gain is less than 23 dB when driven by power of 10 watts or less
- B.The equipment dealer assembled it from a kit
- C.It was manufactured and certificated in a country which has a reciprocal certification agreement with the FCC
- D.The amplifier is constructed or modified by an amateur radio operator for use at an amateur station (correct answer)
WhyA dealer may sell an uncertificated external RF power amplifier capable of operating below 144 MHz if it was constructed or modified by an amateur operator for use at their own station. §97.315 lets a dealer sell an external RF power amplifier capable of operating below 144 MHz without FCC certification if it was built or modified by an amateur operator specifically for use at their own amateur station, since that's a homebrew unit rather than a commercial product being marketed, answer D. A low-gain design, kit assembly by the dealer, or manufacture under a foreign reciprocal certification agreement don't by themselves exempt an amplifier from needing FCC certification when a dealer is the one selling it.
