Sean:

Go to http://www.linxtechnologies.com/f_applic.html #00140 -- The FCC Road:
Part 15 from concept to approval, Adobe Acrobat PDF (35K).  This document
provides all the information on what is required for FCC certification of
license-free wireless devices.  I believe they will even perform the
necessary testing for certification if you're willing to pay the cost.

Good luck.

Dennis

Subject: [EE]: Kits?


Hi all,

I am now quite a bit of the way through the tutorial on wireless comms
for microcontrollers (which was discussed here back in March).  I was
planning on making the tutorial itself freely available on the web and
then sell kits for the major design examples.

I have been doing some research of FCC rules and I noticed that they make
a rather sharp distinction between purely home-build devices and kits.
Home-built devices do not need any kind of certification, provided that
you only build 5 of them and use good engineering practice to try to meet
the specs.

It appears, though, that if I were to sell kits, I would have to apply
for FCC certification for an intentional radiator (for the transmitters,
anyway) and possibly regular certification for any of the devices which
use frequencies higerh than 1.7MHz. Is this correct? I have bought quite
a few kits during my time as an electronic experimenter, and I never
remember any FCC data on them (even for transmittes). Is this rule
generally not enforced and ignored, or am I interpreting it correctly? If
it is ture, can I get around it by just selling a PCB and offering a
selection of parts which would just happen to allow you to build the
devices on the site? While I am putting a lot of effort into this and I
think the result will be very useful to people, I am working on a rather low
budget and I don't think I could afford to make all th measurements
needed for the certification process.

Thanks in advance for any advice,

Sean
