I am looking into getting an amteur radio license and purchase a mobile radio mostly for travel in the midwest and western United States. I currently use CB and find it usefull for highway traffic, but I would like to find something that would be usefull for emergencey situations especially in areas with limited cell service, not really looking to make contacts. I plan on GMRS hand helds for hiking as well. For the mobile what bands or frequecies would be usefull? Should I look into APRS? What power levels? Which level license would I need? I appreciate any advice on the subject. Thank you
