I remember when Ka/Wide/Superwide band was being released in early 90's and the inital report (with SW Ka) was that the possibility that the police radar units would have the capability to easily change the frequency slighty within the unit to make it difficult for detection. In other words, the entire SWKa spectrum was wide open.
I have not kept up with the changes in KaSW band operation over the last 13 years, but reading many posts on this forum, it appears that Ka is operated in only 3 frequencies within the SWKa frequency range allotted by the FCC for police radar? Is this correct?
Any comments/observations appreciated.
