   Because neither the FAA nor the FCC have many technical experts left.  So   
   it takes a long, long time for technical issues to trickle up from the few   
   technical people through all the lawyers up to the top.   
      
   European countries dealt with this quickly and efficiently.   
      
   And the honest truth is that for modern radar altimeters this isn't a   
   problem.  But there are plenty of planes out there flying whose radar   
   altimeter receiver is just a horn and a diode detector.  They were designed   
   that way because there wasn't any use of adjacent bands so nobody bothered   
   putting money and effort into making them any better.
