Re: Can I upgrade to recieve marks system.
If you mean the State of Ohio MARCS system, then you need a digital trunking scanner. The Radio Shack Pro-96 and PRO-2096 will work as will the new GRE 500/600 units and a couple of Uniden Bearcats. They must say "Digital Trunking" or "P-25" for it to work on Ohio MARCS.
