Thanks to all who've addressed this question too. Changed the 
DOPPLER.SQF file just before the 18:30 pass, and it worked fine. All the 
help is certainly appreciated by this new satellite operator. I'm up to 
71 grids worked now, and hoping for more.

My latest foray is into the exciting world of attempting real time 
packet QSO's via ISS.
