The only legal way to transmit on this band is:
- by purchasing a device which has gone through the approval process above. described in FCC part 15.
- to be a manufacturer developing a product using good engineering practices to keep radiation to a minimum.
- to construct home-built experimental device defined under 47 CFR 15.23 and constructed with good engineering practice and Part 15 emission limits
- to be a licensed amateur radio operator using commercial or home-built equipment operating according to power and out-of-band emission limits.
- an approved ISM (industrial, scientific or medical) non-intentional radiator - FCC part 18.

I can trace 4 of those 5 to specific sections, but not the "manufacturer developing" case. Do you happen to know whether/where/how that's addressed in the regulations?

(I'm not subject to FCC jurisdiction, but am interested in understanding the approach to various problems as background for discussions with our own regulator.)

Roland,

Since this is an off topic discussion I will keep it brief. Manufacturers of RF equipment in the USA are subject to the rules laid out in the code of federal regulations (CFR) 47 2.805 when testing their products prior to approval by the FCC. The rules changed in 2013 to be more restrictive fro certain types of products. Links below.

(CFR) 47 2.805
2013 update

In order to abide by the rules for this group this will be my last post on this subject.

Roger
