I just had a pass (and worked PD5DJ, thanks!) and I also noted a downward
shift in frequency as I had to select the next downward shifted frequency
earlier than gpredict was showing. Gpredict has the default 436.7950 in
its configuration.

I can't give exact numbers as I was busy trying to hear/make a contact but
there is some downward shift.
