Thanks Rick,

I've just been experimenting and the numbers do bounce around.  Using the rejection percentages as you suggest looks good.  In my case, they follow a downward trend with increasing SH and I got 0.032% and 0.069% and the MNR was less than 0.5% from the no-rejection figure so I didn't bother going further.  Thanks for the help!

Cheers
Charles

Sounds good, Charles!  It doesn't take long to get a good feel for what amount of rejection is "right" for your particular kit and typical targets.

Cheers,
