My newly acquired RX65, M4, v6.1 (I've yet to see anyone post with this version), has a setting between Pop and LSR identified as "Ku".
I searched the Forum and found nothing. A search of the web indicates that:
"The Federal Commumications Commission (FCC) has allocated 13.45 GHz in the Ku band for traffic radar use in the United States, however Ku radars are not sold or used in the U.S. Some European countries are reported to use Ku band (13.45 GHz) traffic radars."
Is the above statement true? Has anyone seen Ku radar used in the U.S.?
