yes voltage was 13.8 at 30 amps. I got it to come back on after setting for a week with no mic and no power but something isn't right. it keeps keying up for 1 or 2 seconds over and over with nothing hooked up to it. vox is off. idk I think I need to call btech. I noticed the radio says its a GMRS 50v2 on the housing but on power up it says its a GMRS 50x1 on the screen. so, I think I got got. the 50x1 has all sorts of issues. and its cheaper.
