ARDUINO NANO DDS VFO 

ARDUINO NANO DDS VFO built by Carl, WB0CFF. Thanks Carl, excellent work . As you can see this VFO puts out a stable and healthy signal on 7 MHz. Next step is to build a 49er QRP transceiver, and swap out the crystal oscillator circuit with this DDS VFO. If that works out, I will post another video. By the way, Carl programmed the DDS to tune in steps down to 1Hz for CW, I will show that later. 73 Lynn NG9D
