Gaham,
 
>50 ?  That's  quite  low ,  I was  expecting  much  higher  ? that's  for  a  'large'  system ?  do  you  have  a  >ball park figure  for the  max  frequency   change  on that  ?
 
For a SWR BW of 1.5 RFsim says around 1.1kHz,that's to say +/- 550Hz,assuming
all losses are represented by the 50Ohm total loss resistance.
For a SWR-2-BW it's 1.9kHz.
