If I am right, it means the transmitter is sending ..010101010101.. at 50 
baud.  It spends 20mS on F1 then 20mS on F2, where (F2-F1)=50Hz. This is 
eqivalent to a carrier half-way between the two which is being coherently FM 
modulated with a 25 Hz squarewave, so you see a tone in the middle, two 
either side at +/-25Hz, then two more a little lower in level, and maybe a 
few more pairs further out if you look hard enough.
But I am guessing a bit. I can't hear it at all!
