They are using the Ohio Marcs-IP system. Sometimes they (The ems-vfd's) still use the county east 155.415 and they do still use the 155.295 for fire paging but 99% of the time they are on Marcs-IP
You're best bet is to listen to the Belmont C.I. site if you can hear it cause it will have most of Harrison co. sheriff and most vfd's and some times cadiz pd
they use ohio marcs cause i live in cameron and im able to pick up harrison county sheriff and sometimes harrison county fire and ems and its coming from the bridgeport tower site up on kirkwood heights road
