I drove through Hartford twice on my way to and from NYC. For Hartford, the police were still on the EDACS. Audio was pretty good, but I don't know what how well the system works for the police in the field. For the FD, dispatch was clear on 154.310. I heard tones, but nothing else on the "Dispatch" TG on the EDACS and nothing on the 800Mhz system.
The W. Hartford P25 system worked much better than their analog system ever did. At least to my ear.
The CSP system, worked well from the MA state line all the way down to the NY state line. I found that setting the filter on my SDS200 seemed to improve reception. I'll have to update my CT FL file as more local systems come on line with the new system.
