It seems there is no way for me to contact Paul through his Blog. I too have some AD9850 DDS modules working now and would like to do the same thing with a BitX. However, the 1Vpp DDS output seems too low to properly drive the BitX first mixer (for example). Perhaps Paul can share how he interconnects the DDS modules with the BitX. Thanks, David WB4ONA
