You should select your county, then check for available systems. Generally, trunked systems are listed under the county heading, with only a few exceptions. That will show you the systems that the database has listed as existing in your area.I don't know, it won't tell me
You are correct about AEP being the only trunked system in Northeast KY.The only "trunked" system I found in KY is American Electric Power, is this the system you are downloading?
What County are You located in?I'm sorry, I didn't see the other replies.. I can see by the replies that I should have tried the conventional system first and that is where I'm going now.
