It was really easy to do. You ned to have a computer that can run 24/7, a scanner (programed to your area) and the software from radio reference. The only cost I had was a wire that ran from my scanner head phone jack to the mike line on my computer. It only cost me about $17 and I was up and running.
You have to apply for the software and you will need to fill out all the questions in the way that they are wanting them done.
Make sure that you go to the live feed tap at top of the radio reference hme page to get all the info. and form to fill out.
