#32: Quick test of completed DDS-60 from AMQRP/NJQRP
I assembled this AMQRP DDS-60 synthesizer kit for a fellow ham. It uses an Analog Devices DDS chip, a reference oscillator, RF output buffer and voltage regulator. I built a quick jig to program the device using the parallel port of an old computer.
