Replace the radios that manage to disappear when in the field or stream. Handy when you are hunting + fishing with buddies.
a rule of thumb on any radio, its 1 mile per watt. Using that rule these radios need to be transmitting at 26 watts. I don’t think so.
Typically this type of radio will have at most 1 watt of transmit power and will work on FRS as well as GMRS and yea you do need to have a license to use the GMRS channels.
