First time doing this.I am taking an Icom IC-746Pro to Belize with me.I planned to do it as a carry on.
Above all else, remember to put an
original copy of the instruction manual on top! It
must be the first thing any inspector sees when (s)he opens the case!
Trust me on this: you'll have a much easier time of it when the people who are questioning you have an instruction manual that clearly shows they are looking at a "packaged good", i.e., something manufactured for a specific purpose with a well-known, and well-defined, set of capabilities.
Second, and
almost as important, is to have
large copies of
both your U.S. and Belize Amateur licenses, clipped to the back of the instruction manual so that the inspector sees them as soon as (s)he turns the instruction manual over.
Your job is not to get a <mysterious and complicated electronic device> past customs. Your task is to remind a bored, tired public servant of how special (s)he felt when (s)he first heard a BBC shortwave signal.
FWIW. YMMV.
