Amazing. I've been out of the scanner world for so long I never thought I'd understand this BCT15, but I finally do. Quick keys are like little scanners of their own. You can stack them with anything you want. They remind me of banks but you have 99 of them instead of 10. I have all kinds of aircraft channels in key 4 for instance. If I want to listen to the Atlanta route I just move it into it's own key and scan it. Well, I don't have to tell you old timers this but It was like it just dawned on me what this scanner can do. Money well spent. Now if I can only decide on a base antenna.
