Re: LF: Radio signals

[Alex Deligiannis <sv8qg@otenet.gr>]

...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
That's exactly how VOR works
