I've recently been looking into getting a CDM1250 and I'd like to make the equivalent of a HAM Go Box, but for a commercial band radio. This would be for public safety and commercial use. I remember seeing a few on eBay a while back that were pre-built but I have been unable to find them since. I'm interested in building my own but I am unsure whether this would even be a feasible option. My hope is to have a unit that could be charged from a standard wall outlet but have its own dedicated power supply. Could anyone point me in the right direction?
