Warning: The TYT 9000D 2 meter, 220, and 440 radios all are built the same. I have ruined 4 of them the same way. If the radio is turned on and for any reason the power drops out, that radio is DEAD, DEAD, DEAD. There is a fix for the problem but you better be really good at working on really small components. I didn't throw mine away because one day I might get the gumption to completely remove the circuit board and install a jumper across the offending component. If you own one of these radios, make sure you TURN it OFF before removing power to it. I had the lights in my house BLINK off and back on and it took out my 2 meter TYT 9000D, my 220 TYT 9000D, and my 440 TYT 9000D. I even lost one in the car because I forgot to turn the radio of and the car battery went dead. All happened a while back and I'm just getting around to bringing it everybody's attention. If you have one and the brains get scrambled, don't junk it because it actually can be fixed.
