Mixer and audio amp work! Don’t have the rest of the Soldersmoke direct conversion receiver done yet. But I used the digital VFO for my 2m radio homebrew project to feed the LO port on the mixer. Used my 2m FM HT to give some signal toward the exposed end of the coax. At first I heard just screeching. Then realized one side of one toroid was backward phase. Fixed that and could hear myself on the speaker! 🔊 #HamRadio #AmateurRadio
