Hi, I'm trying to reconstruct the raduino (DDS-VFO) for a BITX40. I used an arduino nano, a 16x2 display, a 10K multiturn potentiometer and a Si5351a card. All provisionally mounted on a breadboard. The scketch used is the raduino_v1.27.7 version
I copied the schematic connections and the arduino and the display work. Except that the frequency range is around 7.060 to 7.160 instead of 7,000 to 7,300 and I haven't tried it yet if something comes out of the Si5351!
Has anyone already tried to do it again ???
Thanks and sorry for my English.
