looking for a PIC

Keep in mind I know totally nothing about FCC and other certifications

I already knew that. I was responding to languer.

Read the FCC Part 15 Regulations. They spell out in great detail what is acceptable along with test procedures. A friend with more recent experience as a radio engineer tells me enforcement has been very lax for the past 15-20 years as budget cuts have left them with fewer people.

For unintentional radiators you want to try and shove yourself (I think) into "§15.103: Exempted devices". In my experience we mostly work with "digital device utilized exclusively in any transportation vehicle including motor vehicles and aircraft". However, the "certificate of conformity" comes in the form of a slew of regulatory tests not required for FCC, but required for a different agency.

Looks like the stuff you're doing is not commercial (i.e. you're not making money or commercializing it), and may perhaps fall under "§15.23: Home-built devices" if you claim that each one you modify is unique in of by itself.

I have not worked creating part-15 devices outside my normal work (where we normally are exempt because of all the additional regulatory testing done anyways); but I'm always interested in hearing how other people approach it.

A couple of useful links:
http://www.arrl.org/part-15-radio-frequency-devices (look into the Verification section)
http://www.part15.us/ (a place for questions)

Thanks.

I've used the home-built exception for some kits I designed and a grandson sold several years ago but, in this case, I do not want to put these volunteers cross-wise with the FCC so I'm going to tell them I don't think we should proceed and recommend they spend their funds on some $100 (probably less in volume and even less if there are tax advantages for the manufacturer) units that will dial 911 + 4 other numbers. Perhaps they can use the pendant-less units for spares.
