First of all, the SAT DigiMod isn't going to do anything except show you what birds you're locked onto, as well as signal strength.
second of all, is the GPS jittery when you're stationary or mobile? If it's when you're mobile, it's likely lag time in processing the plotting of the NMEA data due to slower hardware or somesuch.
If it's when you're stationary, it's normal.
