I am a new Redline 360 owner. I am in the Cleveland OH area. I am noticing that my Redline doesn't seem to go off when I pass some local PD and State Troopers, they are clearly shooting radar but the detector stays quiet. I know it works because when I pass stores or some digital signs, or sometimes seemingly randomly it will go off. But even today I passed two locals on the highway clearly shooting radar and nothing, passed right next to them even. Passed right next to a trooper shooting radar the other day and nothing either. I have been made aware of them sitting thanks to Waze and the Highway Radar app. K-Notch is not on, I am thinking about turning it on though, I am not sure what frequency OH uses. Honestly, I haven't used a detector since probably 2007. I used to always use the Cobras and never had issues then. What made me recently get one was because I was visiting my friend in OK and she has a Cobra Road Scout and it seemed to pick up radars from 1-2 miles or better. Browsing YouTube seems like people have been having success with the Redline 360c. I am just getting back into the radar detector game so excuse my ignorance with some things. Can anyone help, are my settings wrong, or should I just try and return it and get a Cobra? Thanks in advance.
