   Not a problem.  There are 2 different problems that you may be talking   
   about.  The difference in phase of the RF signal will have no effect.   
   The RF part of the signal is taken out in the receiver and only the   
   audio is there to be affected by the location of the 2.  And that will   
   have no effect, because the wavelength of audio signals is over 9 miles   
   for the high end (20 kHz) frequency and goes up from there as the   
   frequency goes down.  There will not be enough difference to have   
   any effect.   
      
   And it isn't even April 1.
