WRT FCC radio license
Go to the FCC website (poorly designed, btw) and apply for a FCC Restrictec Radio Operator's License. It is mostly for the Feds to get $60 out of you, otherwise a useless piece of paper. OTOH, necessary for Int'l ops. I just got an Asian validation and my 42 year old, well-worn, been in the ocean at survival school license wasn't good enough for them-- got another one. Expensed it, though.
