It appears that the Conway Sheriff, Morrilton PD, and Plumerville PD use DMR digital which the 1065 cannot decode. There is a P25 digital law dispatch talkgroup on the AWIN statewide trunked system that is used for interop and backup for the UHF DMR frequencies.
With your WS1065 scanner you can monitor analog frequencies plus the statewide AWIN P25 system (until it's fully upgraded to P25 Phase II) and desired talkgroups on it but the db shows Conway Co to utilized some DMR (digital mobile radio) mode communications which the WS1065 will not receive.
