I've been observing a new TGID on MARCS 36416 off of the Dayton and West Alexandria tower sites. Yesterday, traffic was sporadic starting mid morning, nil heard through most of the afternoon. It picked up quite a bit overnight though. This appears to be an agency in Preble County, possibly a TAC for the Sheriff's Office, as the light traffic doesn't seem to make it a dispatch channel. RID for the base unit is 2080 and lots of mentions of 68-### units used by Preble County. Base unit sounds like the SO Dispatcher heard on 155.6100. We will need further monitoring/observation from members in or near to those tower sites. The College Corner site is also a good possibility for traffic.
