i am new to scanner and I purchased a 346xt about a year ago and had it programmed for sacramento county and it worked fine. Then i dowloaded freescan and tried to add some new talk groups, then it would not work at all. I have not been able to use it at all, I have read the easy manual but i just dont understand i have a hard time reading some thing and understanding , if i do it i pick it up fast but reading i just get confused. Any help would be great
