Hi:
I'm also in Clermont county. Union Township Fire Department typically uses 154.1750 for their frequency. I haven't heard them on any other frequency. Years ago, I believe the county used to use some various frequencies.
I'm assuming you're in Clermont county too. If not, maybe just inside Hamilton county. What scanner are you using? Do you have the new Marcs IP 700 frequency system programmed or the simulcast of the Marcs 800 system? Have you tried using both and which works best for you?
Also I was wondering if anyone knows if Union Township PD switched to Marcs IP. I still hear the FD on their regular frequency, bit don't hear the PD since the county switched over to Marcs IP.
Any information would be appreciated. Thanks.
