It looks like Calhoun Sheriff has moved over to MPSCS. Dispatch seems patched to the VHF channel but the units seem to be using MPSCS TG 3235 (Not encrypted). Battle Creek Police seem to have moved to TG 3875 and are usually encrypted. I have also heard TG 3874. This is not listed in RR but is one lower than BCPD and heard in Calhoun County.
I heard some traffic on both of these on the Paw Paw tower a couple of days ago. 3875 was completely encrypted, while on 3874 it appeared that dispatch was encrypted, but the mobiles weren't. Unit numbers in 700's heard.
