Larry, you're probably referring to 851.325 and 853.3375, license WQAM394. Those are licensed to the State rather than to Newberry, so I would be surprised if either of those frequencies were used by a municipality on a full-time basis. Typically these conventional repeaters licensed by the state are used for the state wireless data network for MDT systems. Someone would have to monitor them to see if they're carrying voice or data. I have had 851.325 programmed for Newberry for quite a while and never hear anything on it when I pass through the area every once in a while.
This inquiry prompted me to look through licenses for Newberry County. It seems that they have licensed some new frequencies for repeaters in the last few years that are probably worth checking for activity. Anyone within monitoring range of Newberry, please report what you hear, if anything.
