Notes:
1) I can’t find licenses in the FCC WTB database (http://gullfoss2.fcc.gov/cgi-bin/ws.exe/genmen/index.hts) for 155.595, 154.83, or 155.37. They all show as expired back on October 13, 2000, and were previously under the callsigns KNHA834 and KNHA835. I e-mailed CCSD about this on 12/12/01, with no response so far. UPDATE 01/18/02: CCSD responded to me, and apparently, the radio maintenance company that the county uses forgot to renew the licenses.
2) Sheriff F-1 and F-2 are repeaters; F-3 and F-4 are simplex. Sheriff F-1 tends to get a lot of skip from across the lake in Cook County, Illinois, and I don’t know if they use CTCSS or DCS on the repeater to reduce the interference.
3) I’ve heard Sheriff F-3 called “three”, “LEIN”, and “two” on the air, so my channel numbers for CCSD F-2 and F-3 may be incorrect.
4) The license for Sheriff F-4 is held by the City of Dowagiac. 155.61 used to be the primary dispatch for Dowagiac Police (and Edwardsburg/Ontwa Township Police as well, if memory serves), until all the dispatching was centralized through CCSD a few years ago.
5) “KO5139” is NOT a callsign – it’s a code to indicate that everything is OK. They’ve been using it since the 1970s.
6) “Signal 100” or “100” is the signal to clear the air of all except emergency traffic. This code, too, has been used since the 1970s.
7) Cass County Courthouse security also uses Sheriff F-1, but I don’t know if they are county employees or contracted help. I’ve never heard them use a unit number; the same thing goes for the radio repair people. UPDATE 01/18/02: Courthouse security does not use a unit number at all. Officers are referred to by name over the air, and are usually directed to use F-4, though they do monitor F-1.
8) Fire/EMS F-1 is simplex. Why? I have no idea. IMHO, it should be a repeater system. Also, I don’t know what freq they use for fireground/on-scene comms.
