I just now noticed your location.
The first thing you should have done is download the latest database version, as well as the latest firmware. If it is a new scanner it may not have the updated programming for Ross County.
Ross County recently switched to the Ohio MARCS-IP P25 system. Make sure the scanner is scanning that system and it is not avoided. The old analog frequencies are no longer used. Reduce your range to zero. Hold on the system if the scanner it is scanning other outlying areas.
I pick up Ross County on the south side of Grove City on my HP-2, and I can actually receive them in downtown Columbus on my Unication G4.
