This unit has only been tested to my ability and limited knowledge of scanners. I've had it powered on and in scan mode all morning. I'm in a rural area and I'm hearing mostly fire and EMS calls including tones and talking. I don't know how to test beyond that so feel free to message me with any questions or if you want a specific test performed. This scanner comes with the Uniden power supply, a bnc antenna and an external speaker.
