Did you wonder what the colors mean on the Radio Reference Database? Why are some states or counties green, others yellow, and some grey or white? I'll explain how to decode when new data is added to the database just by looking at the colors on the map. If you have a question about Radio Reference or their Database, let me know in the comments and I'll create a video for you with an answer. #scannerradio #policescanner #hamradio #hamr #radioreference | Scanner School
