As the title says , I am finally giving in & will give the sds a go , Now with being a software radio , I would imagine it is a good idea before messing with it ,..to copy or clone the firmware & sd card it comes with ? I would assume the manual explains how to do this as well , then a screen protector of some sort ,..& I think I have a case that will allow cooling ,.Is there anything else I should know ? I know it is water resistant ,..but does anyone what kind of drops it is rated for ? water resistance is nice but how tough is it if it takes a tumble ? I am going to try to avoid charging within the radio , & using external antennas ,Im not sure if the external charger is smart charger or just a timer that should be monitored more closely , I just want to know the best care & feeding instructions to keep this thing alive
