This is a full kit containing all on-board parts including blue backlit LCD and the DDS chip comes pre-installed on the PCB. If you have a project that you would like to see here, I can add it to my list. 10 postage; From United Kingdom; 0-55MHz DDS Signal Generator Digital Module Shortwave AD9850 For Ham Radio VFO. All I can say is that this kit worked well for me and both transmit and receive audio is excellent. Almost direct connection to an NE602 as vfo (CMOS version tested). It supports a 16x2 line LCD display showing the operating frequency, band and step size. The VFO tunes freely until you stop turning the knob, when it snaps to the nearest of many closely-spaced lock points. Francesco has had several articles published in the Italian Amateur Radio Society journal.
