Not so.  Europe, Asia, and even some parts of Canada use radar frequencies that
differ from X, K, and Ka band that we have here in the U.S.  Bel used to make
a European version of one of their detectors - it worked on the 3 common
bands used in Europe.  Europe has about a dozen or more different bands
licensed.  A number of the bands are right around 10 GHz, so some U.S.
detectors will see this other frequency as an X-band signal.  It will
depend on the bandwidth of the detector are to whether or not it will
pick up the off-band signal.  In general, don't trust a U.S. detector
to work in other places.  After all, every country has their own version of
the FCC which dictates what frequencies are to be used for radar.  They
don't coordinate their frequencies with each other.
