The Wisconsin State Patrol has jurisdictions
on the State's Interstates, US & State Highways. (However Milwaukee
County Sheriff patrol the freeways in that county). Additional channels
are in the patrol radios for the primary area covering the local agencies.
If a radio system is on other than VHF high band, a radio is supplied from
that agency
Troopers identify with three digit numbers with the first digit
being their district number, for example, 255 is in District 2. Inspectors
have four digit numbers with the first two digits being the district number,
for example, 1105 is in District 1.
To call the district communications center, mobile units call
the nearest tower, for example, "255 Delafield." Dispatch calls the mobile
unit like this: "Delafield 255". Mobile units are repeated from one (in
small districts) or two towers. This means that it is possible to hear
the base and not the mobile or vice versa. |
