InstantTrack uses an interface for Doppler tuning similar to the Kansas City Tracker interface for rotator control. The details are provided with InstantTrack in the file INTSPEC.TXT. One extra hint: your radio driver interrupt handler must copy the range rate information into its own memory space, since the information is overwritten immediately after the interrupt handler returns. An example program (rrdemo) is available to demonstrate the technique.
