1-30 MHz Concept Receiver: AM/SSB/CW with Plug-In Resonators, Filters or Crystals
A “concept circuit” is rare among most designers, who usually stick to proven designs. Occasionally, someone builds something novel that proves valuable. This receiver is one such design — offering broadband USB reception without the complexity of typical circuits. SDR-based options exist, but tend to be costly and time-intensive. This one is simple, affordable, and highly effective.
