Really?, Interesting.
Do you know exactly what kind of system it is? I didn't know those "MIKE" / IDEN networks were still around.
I thought they may be on, or about to migrate to a NXDN system or the like, as I have often seen public works people walking around with Kenwood HT's, however they appear to still be used only on analog. You can some times hear them chime in on PW analog freq. but main operations seem to be strictly on what ever they are using now.
