MARCER is starting to try to make the migration from the old 800 system to the new P25 system, but with little success. I've heard KCK and KCMO EMS units trying to call KUMed, OPR, Providence, Children's Mercy, and Children's Mercy South, but with no responses, except from Children's Mercy this week (in fact, they're now regularly replying on the new digital talkgroups to all units that call in on them as opposed to the old system with the other area hospitals). Give it a few more months, and I'm sure that most of the other hospital EDs will start migrating.
FYI for all...MARCER will be making the full P25 transition on Thursday March 15 sometime during the morning hours. This comes from a very reliable source, so watch for new talkgroups to start popping up.
