Hello, I am inquiring about a kit used for AM broadcasting and the kit”s spec are 100mw to the final stage with the included antenna of 3 meters and the ground…. Now Part15 Rules 15.3 indicates (p) Kit. Any number of electronic parts, usually provided with a schematic diagram or printed circuit board, which, when assembled in accordance with instructions, results in a device subject to the regulations in this part, even if additional parts of any type are required to complete assembly. and Part 15.219 indicates: Sec. 15.219 Operation in the band 510-1705 kHz. (a) The total input power to the final radio frequency stage (exclusive of filament or heater power) shall not exceed 100 milliwatts. (b) The total length of the transmission line, antenna and ground lead (if used) shall not exceed 3 meters. (c) All emissions below 510 kHz or above 1705 kHz shall be attenuated at least 20 dB below the level of the unmodulated carrier. Determination of compliance with the 20 dB attenuation specification may be based on measurements at the intentional radiator”s antenna output terminal unless the intentional radiator uses a permanently attached a! ntenna, in which case compliance shall be deomonstrated by measuring the radiated emissions. Now does this mean as long as I buy one kit, build it under the manual for assembly and set it according to the above specs… am I legal to transmit under Part15 Rules? Please indicate where I would be violating the rules? Thank you Nicolas Rios Fuels Systems V22 Boeing Helicopters.
Yes, It is legal to transmit under part 15 Rules with a kit (used for AM broadcasting) that you build under the manual for assembly and set it, which meet the specification.
