The short  answer  is  'No  they  have not'

There is  no  interference  in free  space unless  you  transgress  into 
partial  physics   and  then  the  theories  are  held  together  with 
string
, there  is  that  experiment  with   2 paths , did  a  wave  do  this  or a 
particle ... interference patterns etc

to  get a  resolve  , something  has  to  be  non linear  ,  in this  case 
the  detector  in the  radio , and  the  recovered  signal will  be the 
vector   sum  of the  two  carriers / time    and for  a  spectrum  , then a 
reference is needed to  recover the  modulation  , CIO , to  give 
freq/amp/time    , or  a  complex   w/f  / time  for  a  detector alone
