The speed limit on that part of I-12 was 60 so I was not there for very long. If he was standing out on the highway I would think he was using POP or Lasar.
Question 1) My Pro78 did not go off at all, so can you explain why?
My thinking on this is that maybe he was using POP, and maybe he did not have the trigger pushed at the time I was passing him. BTW, my Laser setting was turned to the ON position so I would not think it was a Laser gun.
More than likely he was using LIDAR (laser). It is extremely difficult to detect laser when you're close because the beam is so narrow that it doesn't reflect up to the sensor in your RD. If you were close enough to see he wasn't squeezing the trigger, it was way too close to detect LIDAR without a jammer.

Your RD would have given you a brief K-band alert, but no POP warning. In other words, it would treat the signal like a normal k-band signal. I have confirmed this with my Pro-78.

Also, sometimes it does not beep at all when the store is closed at night, so am I picking up a automatic door opener or possibly a Alarm system.
Question 3) What do you think about this?
That part's easy. The Pro-78 detects K and X on the same sweep, and this sometimes results in some confusion of the two bands, so sometimes with the X-band off, the RD will incorrectly ID an X-band signal as K-band. Also, it is possible there are two signals there: a strong X-band and a weak K-band. In that case, with X on, your Pro-78 will alert to X-band first because it is the stronger signal. With X-off, it would alert only to the K-band signal.
