The Ethernet transformer mixer with 1N4148 diodes works great! There鈥檚 a contest on 40 today and I have heard Italy, Spain, Russia, Germany, Britain, Belgium, the Netherlands, Switzerland, and Sweden on this radio with that mixer in the last hour. My transformer package contains two sets of transformers. Here I鈥檓 using only one set. But for a superhet radio you鈥檇 have two mixers worth in a small package. #HamRadio #AmateurRadio
