Here is a good article about licensing requirements for VHF and other radio types commonly found on boats: http://www.southwindssailing.com/articles/0304/boatradio.html

I am always surprised when I read these forums and find people asking for info that is readily available on the internet if they would just type in key words and do a search. I know they have internet access since they are posting on this forum. I am prejudiced that sailors are smart people but I often find evidence here to the contrary!

If anyone is thinking about a radio purchase, now is a good time as Boat U.S. and West Marine both have some pretty good discounts on them in current sales, including the Standard/Horizon model (HX470S) that receives VHF, MURS, and FRS bands. And guess what? You do not have to have a store near you to take advantage of the sale since you can look at those offers and order items via the internet!
