I may have missed references to this topic in other discussions, and I apologize if this has already been addressed, but I am curious if anyone knows if the Escort's TSR "tune up" is of any value, and whether the supposed K band false alarm filtering works, or if it may also suppress frequencies that are actually being used by LEOs.
My 8500 X50 has given me fantastic performance for many years, and I'd hate to mess with near perfection. But if I can eliminate K band falsing associated with the construction zone radar in my area and not have to pay for a 9500 or C100, etc., I thought it might be worth considering. I haven't seen anything on this site singing the TSR praises, so I'm curious to hear from anyone who may know about this. In particular, I'm curious about what the upgrade actually consists of and its pros and cons.
