No, they do not have to be working. I can pick up a signal sitting in the garage or driving by but just one way. I have mentioned this before and Roy and Jim were surprised that my opener emits X band but when I moved in 98 I took the opener with me so it emitted X band at my old house as well.
Also a lot of things use X band, we have a trail that runs for several city's and at some street crossings there is a double X band motion sensor that turns on yellow caution lights if someone is coming to the crosswalk.
Fortunately we don't have to put up with X band falsing as we have X off in CA.
