   Technical qustion about wave valleys and troughs and if two radio   
   playing the same station will be in phase wrt all frequencies, or if   
   some will cancel out?   
      
   And why is it low frequencies are famous for cancelling out when out of   
   phase when high frequencies are just as likely, 0.5, I think, to cancel   
   each other out?   
      
   Can I just turn off one radio for a few seconds and turn it on again so   
   that the total odds over both times have increased that by the second   
   time the radios will be in phase?   
      
      
   I have a radio and tv in one bathroom but neither in the other, which is   
   smaller and adjoins the bedroom.  Sometimes I want to hear the radio   
   which only gets 'loud' if you are in the same room. I can hear it from   
   the bathroom but not enough to understand what is said.   
      
   I have another table radio, KLM, expensive, that I had for about 33   
   years when the speaker switch started to fail**, and I turn that one on   
   too, to the same station, also at maximum volume, and I can hear in the   
   bathroom just fine, but I wonder if some frequencies are out of phase   
   from one radio to the other, cancelling each other, and I'm not hearing   
   them.   
      
   It seems to me, if one radio is farther from the transmitting antenna,   
   by 1/2 wave length, the speakers in the two radios will always be going   
   in the opposite direction from each other.  Maybe.   
      
   In my case, the radios are one above the other, so the distance from the   
   xmtr is very similar.   But what about within the radio, when the   
   heterodyning frequency starts.  What if it starts have a cycle after the   
   first radio?   
      
      
      
   **So I bought the second radio.  The first one has a pushbutton switch   
   meant to connect/disconnect a wooden-cabinet stereo speaker, which I   
   have no room for, and unless I get the switch just right, no sound comes   
   out at all.  (even the on/off momementary contact switch no longer works   
   well, after only 33 years, maybe using it at most 6 times a day, so that   
   6x365x33=66,000 times.  Aren't switches supposed to last into the   
   millions of times?  --- It's failing isn't nearly as bad, because I just   
   keep pushing until it works.  The speaker switch OTOH has a spring that   
   pushes it out, past its sweet spot, so now it's hard to get to connect   
   at all.
