"Why worry about which type of radio is best for emergency and prepper use, when you can have them all at once? In one radio! Turn your walkie talkie into a super SHTF survival radio with HAM-FRS-GMRS-MURS-MARINE-WEATHER-BUSINESS channels. The secret is in the programming.
In an emergency, you may need to communicate with others on the channels they have in their radios. Are they using an FRS radio? Or is it MURS or GMRS? Or are they on HAM? Whatever it is, you are now prepared with all those channels in your radio. Just dial them up and talk.
A Prepper SHTF Survival Comms frequency file for programming VHF-UHF handheld transceivers (VHF-UHF HT) is provided here. This file turns your HT into a wonderful HAM-FRS-GMRS-MURS-MARINE-WEATHER-BUSINESS radio...."
