Two days ago Lake County Sheriff's Department updated their radio system to the newer 800 Mhz frequencies, my old analog scanner that we have had since the 1980's is now obsolete. I do not know enough about scanners (other than how to program my old one) to know what I need to update my scanner. I am in hopes that someone can recomend a reasonably priced digital scanner and how to obtain the right frequencies. Our sheriff mentioned it is a "trunked" system, but I am not sure what that means. Thank you for the help.
