Just for kicks & giggles, I set my X50 to POP ON the other day. My detector falses in all the normal places like usual (supermarkets, hospital, pharmacy). How does it detect POP? Will it flash POP on the display, or will it give either a K or Ka alert (with appropriate signal strength or frequency number - mode depending)? Also, I thought that by putting the X50 in POP mode that it would be MORE susceptible to false alerts. So far, it doesn't false any more than usual. Any advice would be helpful!!!
