I am sorry but I do not even know my model! It is a blue portable. When I click on scan I have the option to click on FIRE/POLICE. After I click on FIRE/POLICE it will do great until I get into the 800mhz range. Once it gets to 800mhz it will find a channel and make a weird noise. I am also interested in getting a mobile scanner for my car. What model would you folks get? I need to know what kind of antenna as well. I really don't want to drill holes, but I have seen a mount that I really like. It slips on the side of the trunk lip. I plan on listening to all different departments ranging from 140-800mhz. I come from Northern Ohio and they have a system called MARCS. Will I be able to listen to this MARCS via a scanner? Thank you for all of the help ahead of time. If I posted this in the wrong section please let me know. Have a good one!
