Yes that's  true , but  for  HF , then  Doppler and  delay  need  to  be 
tested  or  the  mode  will  not  survive  transit
and  500  has  phase distortion in  qsb   , could be  seen  using  Murrays 
psk   propagation   time  delay  measuring  software
seemed to  explain  why  psk31  did  not  work  very  well  at  range (or 
over the  pole  on hf ?)
