Interesting... Maybe they decided to fix it after all. I know Clayton said he could fix it, and surely that's a whole lot cheaper than installing a new siren.
On another note, I found a 7th EOWS 1212 while doing a virtual siren hunt earlier - this one is about 4 miles north of the one in Ross near the intersection of Cincinnati-Brookville Road and Alert-New London Road in Shandon, in front of the old Morgan Township fire department (their FD is now located further up 126 in Okeana).
