Putnam Co uses the channel on occasion, it's a backup to SAFET. Brownsburg still uses 155.5350 daily. Johnson County Sheriff also uses their VHF almost daily. The real question is how many will continue once they have been forced to narrow banding in 2013. Thats when many may disappear from the air forever.
Truth is most departments are still using their VHF channels, maybe not all the time but they do use them, and in many cases they are using those for surviellence and so forth now because they think no one monitors those channels any longer. I have two radios that have nothing but VHF channels from the whole state in them and hear things all over the state, even from departments that are primarily on SAFET.
