As the title says, have you narrowed down the detectors that cause Ka falsing and are labeled as "J" by the V1? Is this happening because they do some form of broadcasting for RDD-defense purposes (for example)?
Lastly... is there an "advanced search" anywhere on this Forum? I use that feature a LOT on other forums and tweaking searches by title or using wildcards often helps me find the exact answer I was looking for. I couldn't find that feature on here.
