A question slightly OT: If a GP328 is programmed with PMR446/FRS/GMRS frequencies. This would enable me to use the correct license free frequencies at different countries and prevent any interferences. As in locally, I use the GP328 with 446 frequencies at 500mW and overseas as in US, I use FRS/GMRS frequencies at 2W or 4W. Would I run foul of any law ? Please advise. Thanks.
