in this video https://youtu.be/QUWm3PIJKnE I show you this is the power supply I am going to use for the GMRS two-way radio repeater/amp. It's adjusted DC voltage up to 14 volts with 30amp output. I will post power supply links on where to buy this. Once I get everything tested. NOTE: it does not come with a power cord, but you can make one very easy!!
