Sorry about the wording earlier, 1 uit works the other 3 dont. Thanks for the info that there probably isn't a parameter that disables the uit. If they were swapped then it was done by tk. Hopefully not intentionally because I know a lot of tk guys and they are great guys and I don't think they would maliciously do something like that just because they lost a contract. I've fixed problems before by reading the manual and reloading software on tac 32's. This was easy because I was trained by tk on how to do this year's ago when the 32's just came out. It was not possible to try this the other day because all the backup thumb drives had been removed from the job before we took over. My question now would be if I make backup thumb drives with the existing software and try to reload will I just be replacing corrupt software with corrupt software?
