Just got my r1 today. I'm using advanced mode. I have k band down to 30 percent for false alerts. I know for a fact there are places close that use k band. My question is, what would be worse. K band at 30 or attempting to use k narrow. I feel like I should up k band to at least 40 if not 50. Looking for something that's reliable enough to catch a legit alert but keep it as quiet as possible/reasonable. Also, how bad would be be to use city mode full time legit alerts wise. Does it nerf it that bad? On a side note, what's up with the menu beeps? They're obnoxiously loud. Ear peircing. Lol.
