Hi Matt
Further to below, I tried your suggestion, and still it didn't work.
In fact, I have now found that the only thing that does work now is to use a
pre-compiled binary that I downloaded for txr
?
Best Regards
Ian.

I tried to change to get the external reference frequency to be 36
MHz, by setting B to 50 (i.e. 0x32) and R to 36 (i.e. 0x24). To do
this, I modified lines 43 and 85 respectively to the following:
ad9510_write_reg(0x06, 0x32); ad9510_write
Best Regards
Ian.

want to read the AD9510 datasheet to help with selecting values.
