• DIY 1KW Dummy Load - F5NPV explores the construction of a cost-effective 1KW dummy load for radio enthusiasts. Purchasing a commercial dummy load can be expensive, but with basic materials such as a metal can, resistors, mineral oil, and a heat dissipator, you can build your own. The article provides a simple guide to assembling the load, including the importance of testing for inductance. The DIY dummy load yields impressive performance, with an SWR of 1.2:1 across multiple bands and the ability to handle up to 1KW of power. This budget-friendly solution is a valuable addition to any radio shack.
