Conventional: air freqs, US Forest Svc 168.725 and CS fire station paging MAY still be simulcast on 154.13. City, county, state MA, LE and fire are on P25 systems.
CSFD does not simulcast on the old VHF freq. Some of the county FD's still occasionally use their old VHF/UHF conventional freqs, but other than that, you'll need a digital scanner.
