Cool, do they have like a cross band rpt from each talk group to the old equivalent VHF freq. Say Dispatch talk Group to VHF Dispatch, TG TAC 1 to VHF Firegrounds 1, etc. or is everything sent on just one VHF channel and you hear a mish mash of the TGs? It would be nice if Wake did that and we could still use all our old VHF Portables etc. and not have to buy expensive new mobiles, etc. Prolly a lot of upfront cost for the county, but saves the departments a heap of money.

In Rowan here's how we've got it set up........
RFD DISP (Rowan County Fire Disp) on the TRS is linked fulltime to the RFD DISP VHF transmitter. Anything said across the 800 TG is transmitted across our VHF dispatch channel/frequency. Vice versa, anything transmitted using VHF in turn goes across 800. When dispatching a call here in Rowan our comm center (Rowan) actually keys the VHF transmitter for dispatch, not the 800 TG though as I said it's transmitted across 800 because of the patch.
EMS DISP is exactly the same way as RFD DISP so I'll not type that all over again.
Here in Rowan we have 35 OPS talkgroups that are shared between Rowan County FD's, and the City of Salisbury FD. Salisbury uses OPS 1-11, while 12-35 are assigned to the county. We are still licensed for our old VHF fireground channels but they rarely get used at all, but the ability to patch them is there. They aren't linked to the system unless communications does it, or a few of the departments that still have the Motorola RIC's installed from back in 1996 when county fire moved to 800. The old fireground channels (4 of them) are more like a "party line" these days. Just about every department in the county still have VHF's in their apparatus for back up.
In Mooresville AFAIK the last I heard they have no fireground channels linked to the 800 system fulltime. That may have changed since I last did radio work over there.
**My apologies for veering off topic and talking about Rowan. Just wanted to give an idea of how we do it, and how Mooresville has a similar set up.**
