the real problem is that radar detector designers are lazy bums,
and every detector made today for X and K bands stole the basic
CMI design that uses 11.5Ghz; the detector detector boxes used
in Canada take advantage of this, as it means that they only have
to look for one single frequency.  a detector used an appropriately
chosen alternative frequency (or frequencies) would not be
detectable with the current detector detector.
