HI there as a ham operator I would suggest getting a study guide and getting at least a Technition license first. THEN start looking for a 2 meter [144-148 megahertz] or a dual band 2 meter/70 centimeter radio [144-148 &440-448 megahertz]
Study guides are easy to get I think Radio Shack MIGHT have them stil,l or go on line to HRO [Ham Radio Outlet] and look up their study guides. [you can order and they can send you what you need to study. ALSO since most if not all who work there are Hams themselves they can tell you what you need for study guides].
Don't buy a radio thinking you'll be able to learn off it. You DO need a study guide, as you need a license to LEGALLY operate it.
