My 940 cried "POP!" for the first time tonight, and I did not know it was even in use in my area. I have been using City-lowX, SWS on, and now POP on as settings.
Can anyone confirm/deny POP use in SoCal (Orange Co., Riverside Co., San Bernardino Co. -- the alert occured at the line between OC and RC). No apparent source ever sighted. Could it be I detected somebody's Cobra RD or what?
