I was driving in a national park in Utah. The road had an outrageously low speed limit.
As I crested a hill, V1 encountered strong X-band. Almost immediately, I also received a Ka-band hit straight ahead.
Two for the price of one, you might say. Because right behind the “Your Speed Is…” sign was a ranger running Ka-band. Pretty good trick, hiding behind that X-band false, but not sneaky enough to fool my Valentine.
