[chirp_users] Legal Frequencies?

"Type Acceptance" is the big concern, and the FCC'S way of imposing limits.
IIRC, even if the channel width, emission type, signal width, modulation specs (% and freq limits)  are met, specific 'type acceptance' might still bite you in the butt.
AFAIK, FRS does not require a licensed operator, but some of the FRS freqs are shared with GMRS and that service DOES require licensing.  FRS is also limited to PwrOut, and maybe even ERP, differing from GMRS.

I'm QRT on this topic now.
