Project : DDS VFO

Construction of my DDS VFO has started 
Below is the front panel with LCD display in place



Below is front panel from behind



Below is every Tuning knobs output and power switch in place




What the back looks like for now , DDS not connected up yet. Just the arduino board and display connected.



Testing software program in the Atmega 328 is working and showing frequency on LCD, so far so good.




Arduino board and ad9850 board in place



Side and back covers on , power switch wired up



Looking good so far, software is working



Nice output level 5.60v Pk-Pk , should be good to drive the ade-1 and SBL-1 mixers
