I did a detailed signal analysis of the Langrange-4 datasets with baudline and posted it to my blog. The target is the Sun-Earth L4 position at the 1420, 2008, and 3991 MHz frequencies. Found many interesting signals. Some with modulation characteristics. Several demo videos too.

Some previous discussion

Some previous discussion about the strange Lagrange-4 3991 MHz signal:

http://setiquest.org/forum/topic/weird-maybe#comment-1459

It is some sort of wideband modulated signal with a ∆1267.226 Hz spacing between tones. The 3991 MHz is further analyzed and discussed in more detail and here:

Here is a plot from the date

Here is a plot from the date of the signal collection showing that NASA's STEREO A & B probes were approximately at the L4 and L5 points.
STEREO L4 equilateral
It is still a mystery how STEREO's 8.4 GHz signal could get down-converted to 3991 MHz by the ATA. Maybe it is some sort of sideband / distortion / artifact? Any thoughts about this?

As far as I can tell there is

As far as I can tell there is no way to tell what the actual center freq is on  data sets so maybe it is a typo.  I thought it would be automatic but I guess someone has to type it in.  It seems the bytes that are supposed to tell you are all the same no matter what data set you look at.  When I tried to read the bytes the way rob explained it always returned 1413.4464.
