I have a pro-96 and im wondering now since i have it will it descramble the fbi and other goverment frequencies in ohio etc. Im also still wondering weather marrysville prison would be on the marcs system, or does it have its own set of frequencies, im sure someone in that area would be monitoring them???? seems like it would be good to monitor if i could find it out. thanks every one for the help, Bill wc8i@yahoo.com
