Just for giggles, I sent an email to TYT about the 3 radios that got their brains scrambled due to a voltage dropout while they were turned on. Apparently, TYT radios don't like to have the voltage drop out and then come right back on. They actually answered me and ask for a picture of the display that's scrambled. Then they sent another email in response to my picture email and asked for my mailing address so they can send me the repair parts. We'll see how this goes. I hope I can get the radios back up and running. That would be great. They are all outside of the 6 month guarantee.
