Just got mine yesterday, checked out at 21.5 watts transmiting, installed in the Rv replacing the handheld I was using there, so far so good, looking forward to using it as mobile base station out in the wilds, talking to the KG1000g in the Jeep or one of the handhelds being used on a hike by people in the family when camping, Since first posting this I have cleaned up the wiring with split wire loom tubing
