WebDec 11, 2024 · Schematic Semantics The DC40 was originally designed by Ashhar Farhan as a receiver that’s easy to construct using parts that are easily and inexpensively available in India. For that he is to be applauded, and his BITX20 design was designed similarly. The parts list calls for things like TV balun cores, nylon tap washers, and 50uF capacitors. WebThe schematic is based on parts that are easily available in India. The transformers are on TV balun cores, and the front end filter is wound on a nylon washer. Those parts are actually harder to come by unless you happen to have them in your junk box. I don’t. how did taco tuesday start
