That night  there  was  heavy   icing  in ny-state , so  the  final  power to the ae , was round 300 watts  , was expecting   500 , but at  that  level, things started to  light up ...... by the  erp listed , must be  up round the  1kw   ,   x4  the  previous   power level , Bob's  PA for  500  is much larger than  the  136

 

But , yes  with  50%  m/s ratio  , energy  drop's  again by  50%   , so  to  test  with  equal  energy , then the  power  has to  be  x2  compared to  a 100% carrier  system   , so all the   equal power tests  are  really   50% biased  before the  start ..

 

So in  static same power min level testing  , its  expected that  a  bias will  show , but  over  longer real  path , then  , I think the  decode  profile has  a bigger  role to  play  ...  ' Horses for  Courses '   as the  saying go's  .......( er,  that's  race  courses  and  not part of  a menu )

 

A  flutter  test  would be  interesting , would  need  some  one with a  'large'  signal  to  run   OP0.5  at  100%   -20 dB s/n min , and  see  what  decode s/n variations where , that  would  give  a 30  second sample  window    , op1  would  give 60 seconds  , but that  may  be too  course
