[Discuss-gnuradio] US no-license for USRP info?

[Michael Dickens]

Looking at < http://www.ettus.com/faq.html >:
"The USRP is sold as test equipment, which has no licensing  
requirements."

Can someone with experience in this area please explain to me the  
relevant -specific- portion(s) of the US law/code regarding the  
USRP?  Please do not say "Part 15" since that's a large chunk of  
writing.  I'm looking for (example) "15.103 (c)" as a specific  
portion (which, btw, is interesting but IMHO not applicable to the  
USRP).  Thanks in advance! - MLD
