For a couple nights HCSO's dispatch talkgroups were simulcasting on the P25 system with the same TGID's as EDACS.
On the west system there are two control channels, one with SID of 1 and another with SID of 5. I haven't been able to get the east system so I can't tell if there's been any activity.
I can tell HCSO dispatchers have different console equipment based on the voice compression on their EDACS transmissions.
