Was moving our cars around tonight and accidentally left my Ka radar on in my car while moving my wife's vehicle with the X50 in expert mode. I use spec all the time when i use my X50. It showed 1 bar at first then 2 bars as i got closer to my vehicle. Ka band antenna was facing forward and one antenna was only used. Did tried it the 2nd time and did the same thing. Ka radar was a kustom golden eagle and showed 35.515 in spec mode.
