I have had my RD for almost a year. I know exactly where Ill get X and K band falses on my drive to work in back. I had it setup to show me all the Bands and how many for the longest time. Tonight I switched it over so it would show the frequency of whichever band. I passed by my usual spot that would set off a false K and nothing happened. Any reason? It has set it off EVERY single time I pass by there. Ill give a shot the next couple of days and see what happens.
