They are sudden (happen within 10 ms) and they happen about once a 
second.  I visualize them by continuously acquiring a GPS signal and 
watching the peak move along the freq axis in the 3D plot of frequency 
vs. chip offset vs. power

These are the DBSRX (MAX211x) parameters as they are in Greg Heckler's 
c++ driver:

d_fdac = 127
d_gc2 = 31
d_diag = 5
d_div2 = 1
d_n = 6304
d_m = 2
d_dl = 0
d_ade = 0
d_adl = 0
d_osc = 3
d_cp = 1
d_r_int = 3
