“DDS60 VFO Controller”
 

Overview

The Midnight DDS60 VFO Controller Kit is an outgrowth of previous designs from Steve Weber KD1JV in which he developed small multi-function boards to control the earlier DDS-based VFO boards from the AmQRP Club.  In this latest version, Steve accommodates the AD9851-based “DDS-60” VFO board, achieving a ‘clean’ 60 MHz sinusoid signal and providing a multitude of VFO, transceiver and keyer functions for the homebrewers.  Further, a 3D printed design of a sample enclosure is available, as is the re-introduction of the DDS-60 in kit form to enable a lower-cost means to finish off the kit.

Note 1: This kit requires soldering 1206-sized surface mount parts, including a rather small 32-pin FPGA controller chip.

Note 2: ‘Offshore’ AD9851 VFO boards may also be used with the DDS60 VFO Controller Kit.

Note 3: DDS-60 Kits (and assembled boards) may be purchased separately here.
