So I was driving out on 80 today with my V1 in A mode. I got one or two X-Band falses and a mini save from PA State Police I/O K Band...got a few blips and decided to slow down and he pulled out in front of me from the middle of the highway to go nab someone else.
While I was driving I noticed two of those K band speed signs where it has the speed limit posted and then a "Your Speed" readout underneath it.
However, I also was picking up strong Ka-Band signals from those signs that they put on the side of the road when there is construction or when they close a lane, etc. Is this something new?...I must have passed like 4 of them and I picked them up on both sides of the road. They had no message on them, just a blank, black looking "screen". My V1 showed a full Ka-Band signal when I passed them...followed by the arrows switching to behind...the rear antenna picked up the signal for a good mile after.
I did a quick search but couldn't find anything about blank construction signs with radar on them, so I'm sorry if it has been answered already or is a common occurance...I'm still fairly new to all of this.
