What type of DIGITAL scanner do you have? Ohio MARCS is digital. If it is Radio Shack, program ALL of the control channels for Summit, Stark, Wayne...everyone around. If it is Uniden, you'll have to program-in all the freqs. in the system, not only the control channels. I get OSP all the way from Akron to Cincy. with the PRO 96 using CC only.
From N. Canton you should get Stark Sheriff, Summit/Akron, Canton, Ohio MARCS (all ore APCO 25 digital) as well as Green/Springfield/Uniontown on an analog trunked system.
