• Homebrew radio receiver
  Detailed plans of my homebrew receiver. Frequency coverage is from below 300kHz to 30MHz. Pictures, schematics, board layouts, parts lists and more can be found here.
• 40 meter CW/SSB Receiver
  The K9GDT 40m receiver
• A 80/40m Direct Conversion HF Receiver with DDS VFO
  Juha (OH2NLT) and Matti (OH7SV) have designed JUMA-RX1, an award winning 80/40m direct conversion HF receiver with highly accurate direct digital synthesis VFO. The receiver is very compact, because it constructed using surface mount components. No coils need to be wound to construct this receiver!
