Ohio here, also the 1st to report radar detector issues. X band always ON, also, s far as I can tell, it seems to do it more on just certain 700-800 MHz freqs. It's really had to replicate as sites and freqs change, plus probably some other unknowns.
I'm also looking at a R7, but I have seen some reports that it also may do this.
If I could 100% replicate it would be a dream to analyze, I just can't I've also tried moving an external mag mount to different locations with, so far, no joy.
I have not tried the 200 mobile to see if it does the same or not.
