Sorry one other thing I need to add here to make this easy....
If you have a radio that is capable of being used on Marine frequencies, it CAN be legally modified to work in HAM bands (if you're a ham radio operator).
Any radio can be legally modified by amateurs to work in the ham bands. But you can't modify a "ham only" to work in OTHER bands (legally).
