im traveling south on the florida turnpike yesterday when i start getting a J alert one after another. i look back and there is a cheap cobra in a car right behind me. every minute it gets J'ed out and then waits a minute and j's out again. it does this like 10-12 times like clock work. then all of a sudden i get another ka alert - then the J - then an immediate ramp up for a FHP sitting in the median. it picked up the real KA radar at 2.3 miles while at the same time J'ing out the cobra behind me. i was totally amazed to say the least. never seen this before - really threw me for a loop. what an amazing piece of equipment.Thank you mike valentine.
