Update 03-15-2017
Early this morning this system became active with a number of talkgroups from the current analog system being patched into this system. At this moment, these are not full-time patches.

Current users of the 2 analog systems will be migrating to this digital system within the next couple of years.


The OASIS radio system is going to be a joint radio system with two connected zones, one for Waukesha County and one for Milwaukee County. Both systems are now on the air with control channels. So far, only radio testing is going on. Here are a few other 'knowns' about the system:

-- The Milwaukee County zone will consist of at least 18 frequency pairs and will be phased in over a 3 to 4 year period.
-- The Waukesha County zone will consist of at least 15 frequency pairs. There will be 2 additional 800MHz frequency pairs used for siren alerting and knox box activation.
-- There will be many shared/interoperability talkgroups on the system (County Chase / Firegrounds / Etc)

Here are some links related to the system:

Click Here For the Milwaukee County's "Radio Advisory Council" (RAC). There is some nice (Albeit dated) information regarding the new system.
