That’s good to hear. So it seems that WSPR is more forgiving than the
documentation suggest and I expected (giving the tone separation with a 4 digit
accuracy...)
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.
