      Hi all,

      After that,the PIC of DDS was broken suddenly.
      I changed that and I can see the spurious@7040KHz is almost gone!

      Any very small spurious can be seen now.
      So I think the spurious cause by the DDS-985X's charactristics and
      also the PIC helps that.

      New PIC(16F84A) is good working.
      Clear spectrum.
