Hearing this talkgroup active today off the Ottawa Simulcast. Not sure how long this has been in use but they are all Muskegon county radio IDs. I'm hearing things like Medic 10, medic 8, medic, 14, medic 13 all stating "arrival" or "en-route back to Hackley". I know Muskegon County is building a simulcast system but I don't think that is ready yet. Anyone have any info?
