I have no idea what this could be but the curiosity is killing me. I've noticed this happen on the same stretch of road for YEARS on several radar detectors.
Every time I pass a very specific part of this freeway, my Ka band lights up like a christmas tree, full bars, then goes back down to nothing. There is no construction sign or anything like that, or any "your speed is" signs
About a mile down the same freeway, it happens with K band.
I experimented tonight using special mode and here are my findings:
Ka Band: 34.732 Ghz
K Band: 24.132 Ghz.
I have an x50 Rev. 5 hard-wired to my Mustang. The voltage reading looks good, about 13.5v when the car is running.
Any ideas what this could be???
Day to day in the city I'm pretty happy with it, but on this particular stretch of this particular highway it seems to false alot.
For anybody reading this in the metro Detroit area: The spot I am referring to is 696 right around the woodward / main exit and generally in that area for Ka band going nuts, and for K band just up 696 a bit further around Couzens/10 mile exit.
I will post this in the Michigan area too just in case.
