Retevis has been putting out some very cool options for lower cost radios. These are no exception. If you need a VHF (Murs) radio for outdoor use, these are great. VHF gets better range outdoors, than FRS, and other UHF options, and with no license needed, it's a great option.
Isaac talks about the different radio types, radio bands, and radio licences that you may need, and how to build a bigger emergency communication plan for your community.
