Product information "50Ohm Dummy Load Kit – Compact QRP Dummy Load for Ham Radio & Beginners"

The 50Ohm.de Dummy Load is more than just a practical accessory – it’s the perfect soldering project for newly licensed ham radio operators, training stations, or portable operations. Developed by DL1FLO (Florian Schmid) and DL9MJ (Matthias Jung) in cooperation with the DARC AJW department and blinkyparts, this open-source kit combines functionality and learning.

What is a Dummy Load?

A dummy load is used to safely test a transmitter without radiating RF energy – the power is converted into heat. Perfect for radio checks, power measurements, and training purposes.

Why this Dummy Load?

  • Compact sandwich design with minimal stray inductance
  • Optimized for QRP operation (not suitable for high power)
  • Handy BNC connector
  • Built-in measurement circuit (diode + capacitor)
  • Two identical PCBs for easy assembly
  • 50ohm.de as a learning platform
  • Lovingly hand-packed in Germany

Kit Contents

  • 2x identical PCBs
  • 20x 1kΩ resistors (3W, 5%)
  • 1x BNC connector (50 Ohm)
  • 1x 10nF capacitor
  • 1x Schottky diode (BAT41)

Perfect for:

  • Young and newly licensed ham radio operators
  • Training & educational stations
  • Outdoor and QRP portable operations
  • Soldering beginners (with detailed manual)

Our motto: "Soldering connects!"

With the dummy load kit from 50ohm.de and blinkyparts.com, you're not only getting a functional RF test device, but also a fantastic learning experience – perfect as a gift or for your own skills development.
