Today I was sitting in my garage messing around with the settings on both the RD's, I turned on X band on both the V1 and the 8500. The V1 does not false when near the 8500 but as soon as I turned on X band the V1 went crazy reporting X. Then I decided to take a little drive to see what if any falses the 8500 would create with the V1. Right after I left the neighbor hood I got a K hit on both the RD's, I look down at the V1 display and it shows 2 threats 1 K (real LEO shooting from fire station) and an X band. I pull into the parking lot of Rainbow Foods and I get 3 K band and an X band from the V1. It seems like when ever the 8500 alerts to anything the V1 picks up a X false, when the 8500 looses the signal the V1 stops alerting to X band. I am wondering if it is safe to run both RD's as long as X band is turned off on the V1. Sometimes I do run both RD's at the same time, and so far I have not seen any interference between the 2. Even though the V1 isn't showing any interference there might be, in detection range right?
