It gets messy. Part 15.19 says that devices subject to certification or validation need to be labelled.
Now the hard part. Is this transmitter one of these devices? Some say yes and some say no. Check Part 15.23 and 25. Notice here they talk about authorization and not certification or validation. Right now I am not in the mood to read the whole Part 15 regs. to find if they equate certification to validation to authorization. If someone else wants to I will welcome their comments.
Don’t worry about it. Just go ahead and use it. If I am on the jury, I will vote that these labelling rules apply to the manufacturers and not the users. You, as a user, have to keep the power input right, the antenna right, the out of band stuff right (don’t overmodulate), and don’t interfere. You are not responsible for the label, but you are responsible for the proper operation of the transmitter.

I’ll respond to this issue of the certification or authorization as I was instrumental on clearing up this issue on Radio-Info regarding the AMT3000 or any other ‘kit’ for AM tramsmitters…. Below is the actual letter and response from the Chief Engineer in charge of OET (Office of Engineering Technology)….

Subject: Response to Inquiry to FCC (Tracking Number 621612)
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.

Thanks for posting your letters. I had read this before and was pretty sure I was on the right track with my answer. It was pretty late and I just didn’t dig around for it.
Though the question has been address many times on the boards, it is good to remind us of your communications.
