Another interesting question to ask you.
Recently, I have been detecting several Ku band alerts after re-arming the Ku band detection again following the advise of my friend who had gotten Ku alerts with their XTR-585. On 3 occassions LEOs were around. This is on Knight Street in Vancouver, BC, Canada, especially on Knight and 49th & Knight and Broadway for you Vancouverites.
On 1 occassion, the officer had his gun pointed towards us and my Whistler just went crazy with the Ku band alert. Very troubling, because I was expecting either a K or Ka band alert.
I thought Ku band isn't used in North America at all. Is my Whistler malfunctioning or our cops here testing with Ku guns?
Any insight on this would be much appreciated.
