New Johnson County P25IP system less than one month away

We’re less than one month away from the opening of the new Johnson County Joint Emergency Communications Center (JECC). The JECC is apparently still on schedule to make its July 1 deadline. Most of the towers for the simulcast 700/800P25^IP network are up and running. Now here’s the fun part for Johnson County scanner enthusiasts — mapping out the system to root out new talkgroups and figure out which agency they’re assigned to.

Already there’s a thread over at RadioReference with a pretty decent chunk of talkgroups figured out. If you’ve been listening to the system, collaborate and share your notes with others. Talkgroups can be figured out by running Unitrunker or by just listening.

If you’re interested, Johnson County EMA will be holding an open house of the JECC on June 19th from 1 to 3 p.m. The JECC is located at 4529 Melrose Avenue in Iowa City. More information can be found on this PDF flier.
