I'd bet half the traffic you hear in any large metropolitan area is not even licensed. Particularly in the Las Angeles basin area. And i would even stretch that to include actual repeaters. I'm even hearing a lot of business using GMRS now, like Motels, Grocery Outlets, Construction Co, Landscaping Companies.. I've had a few landscaping companies try to use my repeater, they are hard to get rid of, they don't care. But when you learn who they are and get in touch with their owner and educate them on the FCC laws they will disappear. Self Policing the GMRS repeater Bands and getting harder and harder, sometimes i just turn it off. Thank goodness for the remote access.
