Hi Minto,
 
I recently tried the same device for a local WSPR 15 test and had the same concern about DDS step size, but it decoded ok immediately.

I am currently TX-ing WSPR-15 @ 472800..
Just finished WSPR-15 programming in my PIC controlled AD9850 + 100W TX
'Normal' WSPR works fine (got lots of spots today) but with a tone
separation of only 0.1831 Hz for WSPR-15 the error in FSK tone separation is
nearly  5%:
Minimum stepsize of the AD9850 = 125.000.000 / (2^32) = 0.0291 Hz. 6 *
0.0291 = 0.1746 Hz in stead of 0.1831 = -4.6% too low

We'll see.
