It looks like the Lake County Public Safety system is a P-25 Phase II system. Your Pro-652 scanner only receives P-25 Phase I, you need a scanner that receives P-25 Phase II.
A Phase II system does not mean that a Phase II scanner is required. As far as what the DB says,
Lake County Public Safety Trunking System looks to be operating with P25 Phase I, assuming that all the new updates to the database are completely accurate since it is new and still being updated. Having a Phase II scanner wouldn't be a bad idea for such a system since they have the potential of switching over at anytime.
I am trying to import the Lake County Indiana consolidated dispatch system (Lake County Public Safety) and it will not broadcast. Can anyone look and let me know if this scanner will work. I have researched it and the scanner is P-25 compliant but it just worn t work.
Since it looks like it is a new system, perhaps things have not settled as of yet. Are you able to TUNE to the control channel and hear anything? Does your scanner display anything on the control channel?
There is a fairly large possibility that you're running into
simulcast digital distortion. This is especially true if you can hear the control channel and see full bars, but the scanner struggles to decode anything. Attenuation might help with reception by a little, but it's largely suggested that being able to point a directional antenna at a particular tower would be better.
