Have a look at
http://www.hallikainen.org/cgi-bin/section.pl?section=15.103 for exempt
devices. This may even be exempt as being in an aircraft (though a small
one). If you can get the clock down to under 1.705 MHz and operate on
batteries, it's also exempt. You are exempted from labeling under
http://www.hallikainen.org/cgi-bin/section.pl?section=15.105 if you are
exempt under 15.103.
