Hi LF,
 
a rare and remarkable selective fadi= ng=20 effect on SXV is currently visible on the LF grabber http://members.aol.com/df6nm/Grabber.htm=  .=20 The period and slant of the colour ripples seem to indicate a second=20 component, which is currently Doppler shifted by -0.05 Hz and delayed = ;by=20 about 5 milliseconds. Still lacking an explanation...
