I Had 2 "J" alerts lately with 35.5 as the signal fades. I have not experience this with 34.7. There are 2 towns where i work where local LEO uses kustom GE. It doesn't happen all the time but noticed this lately having J'd a LEO source with 35.5. Try to notice this too guys if in case you encounter 1.
I brought this up because this is the second time it J'd LEO and i was able to ID the radar unit used.
